NEW QUESTION # 19
Site templates are to be used for the large-scale deployment of 100 Prisma SD-WAN branch sites across different regions.
Which two statements align with the capabilities and best practices for Prisma SD-WAN site templates?
(Choose two.)

• A. Once a site has been deployed using a template, its configuration can be updated or modified by applying an updated version of the template.
• B. The use of Jinja conditional statements within a site template is not supported, thereby limiting dynamic customization options.
• C. Site templates offer the capability to pre-stage device configurations by creating a device shell.
• D. Mandatory variables for any site template include the site name, ION software version, and at least one ION serial number /device name pair.

Answer: C,D

Explanation:
Comprehensive and Detailed Explanation
Site Templates (often referred to as Site Configuration Templates) are a critical tool for the Zero Touch Provisioning (ZTP) of large-scale deployments in Prisma SD-WAN.
1. Device Pre-staging (Statement C):
One of the primary capabilities of Site Templates is the creation of Device Shells. A device shell is a configuration container that exists in the controller before the physical hardware is installed or connected. By using a template, an administrator can pre-provision the entire configuration (interfaces, routing, subnets) for the "Site" and "Element" (Device). When the physical ION device is later connected to the internet and claimed (associated with the shell via its Serial Number), it immediately inherits this pre-staged configuration, enabling a true "plug-and-play" deployment.
2. Mandatory Variables (Statement B):
To successfully instantiate a functional site from a generic template, specific unique identifiers are required in the variable data set (typically a CSV file).
* Site Name: Identifies the location in the portal.
* ION Software Version: Ensures the device boots to the specific validated code version required for the deployment, preventing inconsistencies.
* ION Serial Number / Device Name: Required to bind the logical configuration (Shell) to the physical hardware. Even if the serial is added later during the claim process, the structure of the template and the deployment workflow mandates these variables to ensure the device can be uniquely identified and managed within the fabric.
Note on Option D: While it is technically possible to re-deploy a template, the Best Practice for "Day 2" operations (updating or modifying configuration after deployment) is to use Prisma SD-WAN Stacks (Network Stacks, Security Stacks, etc.). Stacks allow for granular, policy-based updates across multiple sites without the destructive or rigid nature of re-applying a full site initialization template. Therefore, D is not the aligned best practice.

NEW QUESTION # 20
A branch manager reports slow network performance, and the network administrator wants to use Prisma SD- WAN Copilot to quickly identify if a specific user, by source IP address, is consuming excessive bandwidth as well as which applications are contributing to this consumption. How can Copilot assist in this investigation?

• A. It can identify the top applications being used across the entire branch and can be correlated with Flow Browser to attribute specific application usage or total bandwidth consumption to individual source IPs.
• B. It will redirect the administrator to the WAN Clarity "Top N: Source IPs" report and the "Flow Browser" utility, suggesting correlation between these tools to determine a user's specific application usage.
• C. It can directly process a natural language query such as "Show top bandwidth source IPs at SD-WAN Branch X over last 3 hours," provide summarized views of the top-consuming source IPs, and view the primary applications they are using.
• D. It will automatically generate and email a "User Bandwidth Consumption" report for the specified branch, which the administrator can use to find the top user and the application details.

Answer: C

Explanation:
Prisma SD-WAN Copilot is an AI-powered operational tool designed to simplify network management through Natural Language Processing (NLP). Traditionally, identifying a bandwidth "hog" required manual navigation through multiple dashboards, such as WAN Clarity and the Flow Browser, to correlate source IP addresses with specific application flows and timestamps. Copilot transforms this workflow by allowing administrators to interact with the system using conversational queries.
When an administrator inputs a query like "Show top bandwidth source IPs at SD-WAN Branch X over last 3 hours," Copilot leverages its underlying machine learning models and integrated data lake to aggregate telemetry across the entire fabric. It instantly identifies the specific source IPs responsible for the highest throughput and correlates that data with application visibility. Instead of providing a static report or redirecting the user to other tools, Copilot presents an interactive, summarized view directly within the interface. This view highlights the top-consuming users and breaks down their consumption by application, such as YouTube, Netflix, or business-critical SaaS tools.
This capability significantly reduces the Mean Time to Resolution (MTTR) for performance issues. By bypassing the need for manual data correlation, Copilot provides immediate "Day 2" operational insights. It effectively acts as a virtual assistant that understands the context of the network topology, site names, and time ranges, allowing the administrator to quickly determine if a branch's slow performance is due to an individual user's behavior or a broader infrastructure issue.

NEW QUESTION # 21
A multinational company is deploying Prisma SD-WAN across North America, Europe, and Asi a. The data centers in the North America region have served all regions, but regional policies are now being enforced that mandate each of the regions to build their own data centers and branch sites to only connect to their respective regional data centers.
How can this regionalization be achieved so that new or existing branch sites only build tunnels to the regional DC IONs?

• A. Remove the circuit labels and apply new circuit labels for in-region circuits only.
• B. Create a new cluster for each regional DC ION and move the sites from the existing cluster to the new cluster.
• C. Disable the auto-tunnel feature globally on the Prisma SD-WAN portal and manually create all necessary tunnels exclusively between IONs within their designated regions.
• D. Assign WAN interfaces to distinct Virtual Routing and Forwarding (VRF) instances for each region on the DC IONs, ensuring that branches only connect to the WAN interfaces/VRFs designated for their region.

Answer: B

Explanation:
Comprehensive and Detailed Explanation
To achieve strict regional isolation where branch sites only form VPN tunnels with Data Centers in their specific region (e.g., EU branches to EU DCs only), the correct architectural feature to utilize is VPN Clusters.
In Prisma SD-WAN (CloudGenix), a Cluster defines a logical security and topology boundary for the overlay network. By default, devices may be placed in a "Default" cluster where they attempt to form a mesh or hub-and-spoke topology with all other reachable devices in that context.
To enforce the new policy:
Logical Partitioning: The administrator should create separate VPN Clusters for each region (e.g., "Cluster-NA", "Cluster-EU", "Cluster-Asia").
Assignment: The Regional Data Center IONs and their corresponding Branch IONs must be moved into their respective clusters.
Result: The Prisma SD-WAN controller dictates that devices can only establish Secure Fabric (VPN) tunnels with other devices within the same cluster. This effectively segments the global network, ensuring that an Asian branch never attempts to build a tunnel to a North American DC, satisfying the compliance requirement without complex access lists or manual tunnel configuration.
Option B (Manual Tunnels) is administratively unscalable and negates the benefits of SD-WAN automation.
Option C (Circuit Labels) is primarily for path selection and traffic steering, not for hard topology segmentation.
Option D (VRFs) is used for local Layer 3 segmentation (routing isolation) within a device, not for controlling WAN overlay tunnel formation scope.

NEW QUESTION # 22
A network installer is at a remote branch site to deploy a new ION 3000 device. The device has been racked, cabled to the internet, and powered on. The installer has the "Claim Code" displayed on the email sent by the administrator.
When the administrator enters this Claim Code into the Prisma SD-WAN portal, what is the immediate status of the device before the configuration is fully pushed?

• A. Provisioned
• B. Claimed
• C. Active
• D. Online

Answer: B

Explanation:
Comprehensive and Detailed Explanation
In the Prisma SD-WAN (CloudGenix) Zero Touch Provisioning (ZTP) lifecycle, the device status transitions through specific stages that indicate its readiness and connectivity.
When an administrator enters the Claim Code (or Serial Number/Claim Code pair) into the portal, the device status immediately updates to "Claimed".
This status confirms that the portal has registered the device's unique identity and associated it with the customer's tenant. However, "Claimed" does not necessarily mean the device is fully operational or passing traffic yet. It simply signifies that the ownership is verified.
Once the physical device at the site successfully connects to the internet and reaches the Prisma SD-WAN Controller (using the call-home function), it will authenticate using its installed certificate. Upon successful authentication and the establishment of the secure control channel, the status will transition from "Claimed" to "Online".
Only after the device is "Online" can the controller push the specific site configuration (Device Shell), policies, and IP addressing required for the device to become "Provisioned" and eventually "Active" in the data path. If the device remains in the "Claimed" state for an extended period, it indicates that the hardware has not yet successfully contacted the controller, which prompts troubleshooting of the physical internet circuit or firewall rules upstream.

NEW QUESTION # 23
By default, how many days will Prisma SD-WAN VPNs stay operational before the keys expire when an ION device loses connection with the controller?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: D

Explanation:
Comprehensive and Detailed Explanation
The Prisma SD-WAN (CloudGenix) solution is designed with a separation of the control plane (Controller) and the data plane (ION devices).1 In the event that an ION device loses connectivity to the Cloud Controller (often referred to as running in "headless mode"), the device continues to forward traffic and maintain existing VPN tunnels using the keys it currently holds.2 However, for security purposes, the VPN session keys (shared secrets) used for the Secure Fabric have a finite validity period. The system is designed such that these keys are rotated regularly.3 If the controller is unreachable, the ION device can continue to rotate keys locally and maintain the VPNs for a maximum default period of 72 hours (exactly 3 days).4 If the connection to the controller is not restored within this 72-hour window, the keys will eventually expire, and the ION will be unable to retrieve new authorized key material from the controller.5 Consequently, the VPN tunnels will go down, and the "out of shared secret key" error will be observed in the VPN status logs. This mechanism ensures that a permanently compromised or stolen device cannot maintain network access indefinitely without central authorization.

NEW QUESTION # 24
An administrator is configuring an ION 2000 device for a deployment where high availability is required, but the site has only a single internet circuit. The administrator configures a Bypass Pair (Fail-to-Wire) on ports 1 and 2 connecting the ISP modem to the legacy firewall.
If the ION device loses power, what is the resulting behavior of the traffic flowing through this Bypass Pair?

• A. Traffic is blocked to prevent uninspected packets from entering the network (Fail-to-Block).
• B. The device reboots into "Safe Mode" and acts as a Layer 2 switch.
• C. The internal relay closes, physically bridging Port 1 and Port 2, allowing traffic to flow transparently between the modem and firewall.
• D. Traffic is rerouted to the LTE modem automatically.

Answer: C

Explanation:
Comprehensive and Detailed Explanation
The Bypass Pair feature on Prisma SD-WAN ION devices (specifically supported models like ION 2000, 3000, 7000, 9000) is a hardware-based resiliency mechanism known as Fail-to-Wire.
Operation: A "Bypass Pair" logically groups two physical interfaces (e.g., WAN 1 and LAN 1). Under normal operation, the ION processes traffic between them.
Power Loss: In the event of a total power loss (or critical software failure), a mechanical relay inside the device physically closes the circuit between the two ports.
Result: This creates a direct electrical connection (like a patch cable) between the upstream device (ISP Modem) and the downstream device (Legacy Firewall or Router). This ensures that internet connectivity is preserved for the site, even if the SD-WAN appliance is completely dead. This is critical for single-point-of-failure deployments where maintaining basic dial-tone is more important than SD-WAN optimization during a hardware outage.

NEW QUESTION # 25
Two branch sites, "Branch-A" and "Branch-B", are both behind active NAT devices (Source NAT) on their local internet circuits.
What requirement must be met for these two branches to successfully establish a direct Dynamic VPN (ION-to-ION) tunnel over the internet?

• A. Both sites must disable NAT and use public IPs on the ION interface.
• B. One of the sites must have a Static Public IP (1:1 NAT) to act as the initiator.
• C. The ION devices automatically use STUN (Session Traversal Utilities for NAT) to discover their public IPs and negotiate the connection.
• D. Dynamic VPNs are not supported if both sides are behind NAT.

Answer: C

Explanation:
Comprehensive and Detailed Explanation
Prisma SD-WAN supports Dynamic VPNs (Branch-to-Branch) even when both endpoints are behind Source NAT (e.g., typical broadband connections).
To achieve this, the ION devices utilize standard NAT Traversal techniques, specifically leveraging STUN (Session Traversal Utilities for NAT).
Discovery: Each ION communicates with the Cloud Controller (which acts as a STUN server/signaling broker). Through this communication, the controller observes the public IP and Port that the ION's traffic is coming from (the post-NAT address).
Signaling: The controller shares this public reachability information with the peer ION.
Hole Punching: The IONs then attempt to initiate connections to each other's discovered public IP/Port. This "UDP Hole Punching" allows them to establish a direct IPSec tunnel through the NAT devices without requiring static 1:1 NAT mapping or manual port forwarding on the provider routers, enabling mesh connectivity in commodity internet environments.

NEW QUESTION # 26
Which configuration requirement must be met to allow two branch ION devices to automatically establish a direct Dynamic VPN (branch-to-branch) connection for traffic flow, bypassing the Data Center?

• A. The Data Center ION must be offline to trigger the dynamic failover.
• B. The "Standard VPN" path policy must be selected.
• C. A static "Gre Tunnel" must be manually configured between the two sites.
• D. Both ION devices must be members of the same VPN Cluster.

Answer: D

Explanation:
Comprehensive and Detailed Explanation
Dynamic VPNs (also known as ION-to-ION or Branch-to-Branch VPNs) allow Prisma SD-WAN devices to establish direct, on-demand secure tunnels between branch sites to optimize latency for peer-to-peer traffic (e.g., VoIP calls between offices).
To enable this capability, the primary architectural requirement is the configuration of VPN Clusters.
A VPN Cluster defines a logical group of devices that are authorized to communicate with one another.
By default, or if devices are in different clusters without peering, the topology typically defaults to Hub-and-Spoke, where branches only talk to the Data Center.
When two branch ION devices are placed into the same VPN Cluster (or peered clusters), the controller shares the necessary reachability and cryptographic information between them.
Once in the same cluster, the ION devices monitor traffic. If a user at Branch A tries to contact a server at Branch B, the ION devices detect this interest. If a direct path is available (e.g., via public internet), they will dynamically negotiate a direct VPN tunnel, bypassing the Data Center hub. This offloads the hub and reduces latency. Option B is incorrect because SD-WAN eliminates manual GRE config. Option C is incorrect because dynamic VPNs are a performance feature, not just a disaster recovery feature.

NEW QUESTION # 27
What is the number and structure of Prisma SD-WAN QoS queues supported per WAN interface?

• A. 12 queues
  4 classes1
  3 application criteria within each class
• B. 8 queues
  2 classes
  4 application criteria within each class
• C. 8 queues
  1 priority queue
  7 non-priority queues
• D. 16 queues
  4 classes
  4 application criteria with each class

Answer: D

Explanation:
Comprehensive and Detailed Explanation
The Prisma SD-WAN (ION) QoS engine utilizes a hierarchical queuing structure designed to provide granular control over application performance. Each WAN interface on an ION device supports a total of 16 QoS queues.
This 16-queue structure is derived from a matrix of 4 Classes (often referred to as Priority Classes) multiplied by 4 Application Criteria (Traffic Types).2
* 4 Priority Classes: The system defines four high-level business priority categories:3
* Platinum (Highest priority)4
* Gold
* Silver
* Bronze (Lowest priority/Best Effort)5
* 4 Application Criteria (Sub-queues): Within each of the four priority classes, the system further categorizes traffic into four specific application types to ensure proper handling (e.g., ensuring voice doesn't get stuck behind bulk data even within the same priority level):6
* Real-Time Video
* Real-Time Audio
* Transactional
* Bulk7
Calculation: 4 Priority Classes × 4 Application Types = 16 Total Queues per interface. This structure allows the scheduler to ensure that a "Platinum" voice call is prioritized over "Platinum" bulk data, and both are prioritized over "Gold" traffic.

NEW QUESTION # 28
For how many hours are Prisma SD-WAN VPN shared secrets valid?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: A

Explanation:
In the Prisma SD-WAN architecture, security is built directly into the AppFabric using a centralized, controller-led approach to key management. Unlike traditional VPNs that rely on manual Internet Key Exchange (IKE) or static Pre-Shared Keys (PSKs) which can be administratively burdensome and security- vulnerable, Prisma SD-WAN automates the entire lifecycle of encrypted tunnels. The Prisma SD-WAN Controller acts as the central authority for identity and key distribution for all ION (Instant-On Network) devices within the tenant's fabric.
Specifically, the VPN shared secrets used to secure these tunnels are ephemeral and are valid for exactly 24 hours. This 24-hour validity period is a security best practice implemented by Palo Alto Networks to limit the
"blast radius" or window of exposure in the unlikely event that a key is compromised. The controller automatically handles the generation, distribution, and rotation of these secrets. Before the 24-hour timer expires, the controller pushes new keys to the ION devices, which then perform a hitless rollover. This ensures that the data plane remains active and encrypted without requiring manual intervention from a network administrator. If an ION device loses its control plane connection to the controller, it will maintain its existing tunnels using the current keys until they expire, at which point it must re-authenticate with the controller to receive a new set of valid secrets. This automated rotation is a core component of the Prisma SD- WAN Zero-Trust security model.

A multinational company is deploying Prisma SD-WAN across North America, Europe, and Asia. The data centers in the North America region have served all regions, but regional policies are now being enforced that mandate each of the regions to build their own data centers and branch sites to only connect to their respective regional data centers.

• D. Assign WAN interfaces to distinct Virtual Routing and Forwarding (VRF) instances for each region on the DC IONs, ensuring that branches only connect to the WAN interfaces/VRFs designated for their region.

Answer: B

Explanation:

NEW QUESTION # 30
Which statements accurately describes how the Prisma SD-WAN zone-based firewall functions within a branch network?

• A. East-west traffic between the zones can be explicitly blocked, but traditional Access Control List (ACLs) are required to block north-south traffic.
• B. North-south traffic is handled by application-aware policies, while east-west traffic requires traditional Access Control List (ACLs).
• C. North-south traffic (internet/WAN egress) is handled by zone-based firewall and relies on external firewalls for east-west segmentation.1
• D. Security zones enable granular control over both WAN-to-LAN and LAN-to-WAN as well as east-west (LAN-to-LAN) traffic flows within the branch.

Answer: D

Explanation:
The Prisma SD-WAN (ION) device includes a native, application-aware Zone-Based Firewall (ZBFW) that provides comprehensive security within the branch without the mandatory requirement for additional hardware.2 The fundamental principle of this architecture is the grouping of interfaces and sub-interfaces into logical Security Zones.3 Once these zones are defined (e.g., LAN, WAN, Guest, IoT), the administrator can create security policies that govern the traffic permitted to flow between them.4 Unlike traditional routers that rely on stateless Access Control Lists (ACLs) which are difficult to manage and lack application visibility, the Prisma SD-WAN ZBFW is stateful and application-aware.5 This means it can apply granular control over North-South traffic (flows moving between the LAN and the WAN/Internet) and East-West traffic (flows moving between different segments within the LAN, such as from a Guest zone to a Corporate zone).6 By using security zones, an ION device can ensure that even if two local networks are connected to the same physical appliance, they remain completely isolated unless a specific policy explicitly allows communication.
This "Zero Trust" approach at the branch edge allows organizations to segment vulnerable devices (like IoT) from critical internal resources and strictly control how users access the internet or the corporate data center.7 The ZBFW works in tandem with the global controller to ensure that security postures are consistent across all branch locations, eliminating the complexity of manual ACL management at each site.8

NEW QUESTION # 31
When deploying a branch gateway, secure fabric VPN tunnels are automatically established between which two site types? (Choose two.)

• A. Branch to branch gateway (same domain)
• B. Branch gateway to data center
• C. Branch gateway to branch gateway
• D. Branch to branch gateway (different domain)

Answer: B,C

Explanation:
In the Prisma SD-WAN (Instant-On Network) architecture, the "Secure Fabric" is a key feature that simplifies VPN orchestration through automation. When an ION device is deployed at a site and associated with a specific role, the Prisma SD-WAN Controller automatically manages the establishment of encrypted VPN tunnels without requiring manual IPsec configuration.
The most fundamental tunnel type is Branch gateway to data center (Option B). By default, the system follows a hub-and-spoke model where every branch ION device automatically attempts to build secure tunnels to all available Data Center clusters within its domain. This ensures that branch locations have immediate, redundant connectivity to centralized corporate resources and applications as soon as they are brought online.
Additionally, Prisma SD-WAN supports automated Branch gateway to branch gateway connectivity (Option C). Unlike traditional architectures that backhaul all traffic through a central hub, the Prisma SD- WAN fabric can dynamically establish "spoke-to-spoke" tunnels between branch gateways to facilitate direct communication. This is particularly useful for latency-sensitive applications like Voice over IP (VoIP) or video conferencing. While this can be configured as a "full mesh" where all sites build tunnels to all other sites, the controller intelligently manages these connections based on the defined site roles and domain configurations to optimize resource usage and performance. Options A and D are incorrect because the fabric orchestration logic is primarily focused on the functional roles of the gateways (Branch vs. Data Center) rather than "domains" in the context of tunnel initiation.

NEW QUESTION # 32
An administrator wants to configure a Path Policy that routes all "Guest Wi-Fi" traffic directly to the internet using the local broadband interface, bypassing all VPN tunnels.
Which Service & DC Group setting should be selected in the policy rule to achieve this "Direct Internet Access" (DIA) behavior?

• A. Standard VPN
• B. Direct
• C. Any-Private
• D. Default-Cluster

Answer: B

Explanation:
Comprehensive and Detailed Explanation
In Prisma SD-WAN Path Policies, the Service & DC Group (Destination) field determines where the traffic is sent.
Direct: This is the specific keyword/object used to instruct the ION to route traffic directly out to the local WAN interface (Local Breakout) towards the Internet, without encapsulation in a VPN tunnel. This is the correct setting for Guest Wi-Fi, SaaS applications (like Office 365), or any public web browsing that does not need to be backhauled.
Standard VPN / Default-Cluster: These options direct traffic into an IPSec overlay tunnel destined for a Data Center or another ION. Selecting these would "backhaul" the guest traffic, which contradicts the requirement for DIA.
When "Direct" is selected, the ION uses its available "Internet" category links. The policy can further specify which internet link to use (e.g., "Use Broadband, avoid LTE") via the path preference list, but the Destination type must be "Direct".

NEW QUESTION # 33
An administrator is configuring a BGP peer on a Data Center ION to learn routes from the core switch. The goal is to have the ION learn these prefixes and then advertise them to all remote branch sites across the SD- WAN overlay.
Which setting must be configured on the BGP Peer to ensure these learned routes are redistributed into the SD-WAN fabric?

• A. Set the "Admin Distance" to 20.
• B. Enable "Graceful Restart".
• C. Set the "Scope" to "Global".
• D. Configure a "Prefix List" to deny all.

Answer: C

Explanation:
Comprehensive and Detailed Explanation
In Prisma SD-WAN routing configuration, the Scope setting on a BGP Peer (or a Static Route) controls the redistribution logic for the prefixes learned from that source.
* Local Scope: If a BGP peer is configured with "Local" scope, the ION device will install the learned routes into its local routing table for its own reachability, but it will not advertise (redistribute) these routes to other ION devices via the Secure Fabric. They remain local to the site.
* Global Scope: To advertise reachability to the rest of the network, the BGP peer must be configured with "Global" scope. This tells the ION that any prefixes learned from this specific neighbor (e.g., the DC Core Switch) should be propagated across the SD-WAN overlay to remote branches. This is the critical setting for enabling branch-to-DC communication for applications hosted behind that BGP peer.
Without "Global" scope, the branches would never learn the routes to the data center subnets.

NEW QUESTION # 34
A network installer is attempting to claim a new ION device using the "Claim Code" method. The device is connected to the internet, but the status in the portal remains stuck at "Claimed" and does not transition to
"Online". The installer connects a laptop to the LAN port of the ION and can successfully browse the internet, confirming the uplink is active.
What is the most likely cause of the device failing to reach the "Online" state?

• A. The "Circuit Label" has not been applied to the WAN interface.
• B. The upstream firewall is blocking outbound TCP port 443 or UDP port 123 (NTP).
• C. The device has not yet downloaded the latest software image.
• D. The device is missing the "Site" assignment in the portal.

Answer: B

Explanation:
Comprehensive and Detailed Explanation
The transition from "Claimed" to "Online" depends entirely on the ION device's ability to establish a secure, persistent management tunnel to the Prisma SD-WAN Controller.
* Connectivity Requirements: The ION device initiates an outbound connection to the controller on TCP Port 443 (HTTPS). It also requires accurate time synchronization to validate SSL certificates, necessitating access to NTP (UDP Port 123).
* Scenario Analysis: Since the installer can browse the internet from the LAN, we know the physical link and basic routing/NAT are functional. The issue is specific to the management plane traffic.
* Root Cause: If an upstream firewall (e.g., a corporate edge firewall or ISP filter) is inspecting SSL traffic or blocking specific FQDNs/Ports required by the ION, the device cannot complete the handshake. Consequently, it remains "Claimed" (registered in the database) but cannot go "Online" (active management session). Options A, C, and D prevent provisioning (configuration push) but generally do not prevent the device from initially checking in and going "Online" if the pipe is open.

NEW QUESTION # 35
Which troubleshooting step should be taken when users at a branch site are experiencing a maximum throughput of 200 Mbps for Direct Internet Access (DIA) traffic on a 1 Gbps internet connection?

• A. Ensure QoS policy is applies to the site.
• B. Ensure the WAN interface is set to 1 Gbps or auto mode.
• C. Ensure the circuit configuration at the site level is properly set.
• D. Ensure performance policy is applied to the site.

Answer: C

Explanation:
In Prisma SD-WAN, the effective throughput for any given circuit is fundamentally dictated by the Circuit Configuration defined at the site level. When a branch experiences a "throughput ceiling" (e.g., traffic capped at 200 Mbps on a 1 Gbps physical link), the most likely cause is that the software-defined bandwidth limit for that circuit has been set incorrectly in the Prisma SD-WAN Controller.
Prisma SD-WAN ION devices do not simply forward traffic at the maximum physical line rate by default; they rely on the administrator-defined Upstream and Downstream bandwidth values to perform traffic shaping, policing, and path selection. If a circuit is physically capable of 1 Gbps but is configured in the portal as having only 200 Mbps, the ION device will enforce this 200 Mbps limit to prevent oversubscribing the link and to ensure that Quality of Service (QoS) and path selection calculations remain accurate based on the assumed capacity.
To resolve this, an engineer must navigate to the Site Configuration, locate the specific WAN circuit, and verify that the bandwidth settings match the actual service provider's handoff. If these values are set lower than the actual link speed, the device will artificially throttle the traffic. While ensuring the WAN interface is set to the correct speed/duplex (Option B) is a valid physical layer check, and QoS/Performance policies (Options A and C) manage how that bandwidth is used, it is the Circuit Configuration that defines the total available bandwidth for the SD-WAN fabric to utilize. Correcting this configuration allows the ION device to scale its throughput to match the full 1 Gbps capability of the broadband connection.

NEW QUESTION # 36
When using the CloudBlade to integrate Prisma SD-WAN with Prisma Access, how does the system ensure that the IPSec tunnels between the branch ION and the Prisma Access Security Processing Node (SPN) are kept alive during periods of no user traffic?

• A. The CloudBlade automatically configures the ION to send Synthetic Probes (ICMP/HTTP) across the tunnel.
• B. Prisma Access initiates the connection to the branch every 60 seconds.
• C. The IPSec tunnel uses standard DPD (Dead Peer Detection) and the ION sends keepalives.
• D. The administrator must configure a continuous ping script on a branch PC.

Answer: C

Explanation:
Comprehensive and Detailed Explanation
The stability of VPN tunnels in the Prisma SD-WAN + Prisma Access integration relies on standard IPSec mechanisms.
Dead Peer Detection (DPD): The CloudBlade configuration automatically enables DPD on the IPSec tunnels it provisions.
Mechanism: DPD is a standard keepalive mechanism where the ION device sends periodic "R-U-THERE" messages to the Prisma Access gateway (and vice versa). If no acknowledgment is received after a specific count/timer, the ION marks the tunnel as down and attempts to re-key or switch to a backup path.
Synthetic Probes (B): While Synthetic Probes (part of ADEM or Path Quality monitoring) can be configured to measure latency/loss, the fundamental mechanism that keeps the IPSec security association (SA) active and detects link failure is DPD, not an application-layer probe.

NEW QUESTION # 37
The UI triggers incident DEVICESW_CONCURRENT_FLOWLIMIT_EXCEEDED for a branch site. Based in the image below, which tool can be used to identify the host?

• A. Run tcpdump under the LAN interface
• B. Monitor # Activity # New flows
• C. Monitor # Activity # Transaction Stats
• D. Monitor # Activity # Flows

Answer: D

Explanation:
When a Prisma SD-WAN ION device triggers the
DEVICESW_CONCURRENT_FLOWLIMIT_EXCEEDED incident, it indicates that the number of active sessions has reached the hardware or software-defined capacity limit of that specific appliance. In the provided graph, we can see a massive spike in concurrent TCP flows on May 13th, reaching nearly 500k, which is a clear indicator of anomalous behavior-likely a "top talker" host, a malware outbreak, or a misconfigured application generating excessive connections.
To identify the specific host responsible for this surge, administrators should navigate to Monitor # Activity
# Flows. This interface, commonly known as the Flow Browser, provides the most granular visibility into real-time and historical session data within the Prisma SD-WAN fabric. Unlike "Transaction Stats," which provide high-level summaries, or "New Flows," which only show the rate of session initiation, the Flows view allows an engineer to filter and sort the active session table by metadata such as Source IP, Destination IP, Application, and Site.
By utilizing the Flow Browser, an administrator can quickly group flows by "Source IP" to pinpoint exactly which internal host is consuming the most flow table entries. This is the standard "Day 2" operational workflow for troubleshooting performance and capacity incidents. While running a tcpdump (Option A) is a valid diagnostic for packet-level analysis, it is inefficient for identifying a single host among hundreds of thousands of flows and can further tax the device's CPU during a high-load event. The Monitor # Activity # Flows tool is designed specifically for this type of scale, providing the necessary visibility to remediate the flow limit exhaustion and restore normal network operations.

NEW QUESTION # 38
User-ID integration is configured for a Prisma SD-WAN deployment. Branch-1 has the user-to-IP mappings available, and User-1 is mapped to IP-1.
To which two use cases can User-ID based zone-based firewall policies be applied? (Choose two.)

• A. User-1 accessing a private application within Branch-1, and source User-ID based zone-based firewall rules on Branch-1 ION
• B. User-1 accessing a private application in Branch-2 via SD-WAN overlay, and destination User-ID based zone-based firewall rules on Branch-2 ION
• C. User-1 accessing a private application in data center via SD-WAN overlay, and destination User-ID based zone-based firewall rules on DC ION
• D. User-1 accessing a SaaS application on direct internet and source User-ID based zone-based firewall rules on Branch-1 ION

Answer: A,D

Explanation:
Comprehensive and Detailed Explanation
In Prisma SD-WAN (CloudGenix), Zone-Based Firewall (ZBFW) policies rely on the device's ability to map an IP address to a User-ID to enforce identity-based rules. The key to this question is understanding where the mapping exists and which direction the policy attributes (Source User vs. Destination User) apply to.
1. Mapping Location (Branch-1): The prompt states that Branch-1 has the user-to-IP mapping for User-1.
For the most effective and scalable security enforcement, policies should be applied at the source (ingress) device where the traffic originates and where the user identity is known. This prevents unauthorized traffic from consuming WAN bandwidth only to be dropped at the destination. Therefore, the Branch-1 ION is the correct enforcement point for User-1's traffic.
2. Source vs. Destination User:
* User-1 is the Source: In all scenarios, User-1 is the initiator of the traffic. Therefore, the security rule must match on Source User-ID.
* Options C and D are incorrect because they suggest using Destination User-ID based rules to control User-1. Destination User-ID rules are used when the target of the traffic is a known user (e.g., VoIP calls to a specific user's phone), not when filtering based on the sender. Furthermore, relying on the DC or Branch-2 ION to enforce policies for User-1 would require the propagation of User-ID mappings across the overlay, whereas local enforcement at Branch-1 is the standard architectural model.
3. Valid Use Cases (A and B):
* Option A (SaaS/Internet): The Branch-1 ION acts as the internet gateway. It can use the local mapping (IP-1 = User-1) to allow or deny access to specific SaaS applications (Direct Internet Access) based on the user's identity (e.g., "Allow Marketing Group to access Social Media").
* Option B (Internal Segmentation): The Branch-1 ION can enforce policies for traffic moving between local zones (e.g., from a "Users" VLAN to a "Servers" VLAN within the branch). Since the ION routes this traffic and holds the mapping, it can enforce Source User-ID policies to secure local private applications.

NEW QUESTION # 39
BGP core peers on data center IONs are learning only a default route from the core router. Which action will protect the SD-WAN network from getting isolated in the event of BGP misconfiguration on the core routers?

• A. Configure BGP max-prefix limits on the ION devices to prevent them from accepting too many routes from the core routers.
• B. Enable BGP Bidirectional Forwarding Detection (BFD) on the core peer sessions to rapidly detect BGP neighbor failures.
• C. Add a static default route with higher admin distance pointing to the core peer IPs.
• D. Implement BGP route filtering using prefix lists and route maps on the ION devices to only accept specific, known prefixes from the core.1

Answer: C

Explanation:
In a Data Center (DC) deployment, the ION device typically peers with a core router via Border Gateway Protocol (BGP) to exchange reachability information between the SD-WAN fabric and the legacy corporate network.2 When the ION is configured to learn only a default route ($0.0.0.0/0$) from the core, the entire SD- WAN fabric relies on this single BGP-learned route to reach internal resources not directly connected to the ION.
The primary risk in this design is network isolation caused by a BGP misconfiguration or a "soft failure" on the core router. If the BGP session stays "Up" but the core router stops advertising the default route due to a configuration error, the ION device will remove the route from its routing table. Without a valid path to the core, the branch sites connected to the DC ION will lose connectivity to all data center resources.
To mitigate this, the recommended best practice is to add a static default route with a higher Administrative Distance (AD) pointing to the core peer IPs.3 This acts as a "floating static route." Under normal operations, the BGP-learned default route (typically with an AD of 20 for eBGP) remains active in the routing table. If the BGP advertisement fails, the static route with the higher AD (e.g., 250) becomes active.
This ensures that the ION device maintains a persistent gateway toward the core infrastructure, preventing total fabric isolation and providing a fail-safe mechanism while the BGP peering issue is remediated. While BFD (Option A) helps with fast peer failure detection, it does not solve the issue of a missing prefix advertisement. Static route redundancy provides the necessary architectural "safety net" for the data center's reachability.

NEW QUESTION # 40
In the Prisma SD-WAN portal, an administrator is viewing the "Media" analytics for a branch site to troubleshoot complaints about poor voice quality.
When calculating the Mean Opinion Score (MOS) for voice traffic, which two metrics does the system prioritize active monitoring for, even when no user voice traffic is present on the link? (Choose two.)

• A. Packet Loss
• B. Jitter
• C. Latency (One-Way)
• D. Throughput

Answer: A,B

Explanation:
Comprehensive and Detailed Explanation
Prisma SD-WAN calculates the Mean Opinion Score (MOS) to provide a standardized metric (1-5) for voice quality. To ensure the system always knows the "voice readiness" of a path-even before a call starts-it uses Active Probes (synthetic UDP packets).
While latency is measured, the MOS calculation algorithm is most heavily penalized by Packet Loss (D) and Jitter (B).
Packet Loss: Even a small amount of loss (e.g., >1%) dramatically reduces voice clarity, causing dropouts.
Jitter: High variance in packet arrival time (jitter) causes the "robotic" voice effect and buffer underruns.
The system continuously measures these specific metrics on all WAN links using synthetic probes. If the packet loss or jitter exceeds the threshold defined in the "Path Quality Profile" (e.g., Voice Profile), the path is marked as non-compliant, and the MOS score drops, triggering a policy action to move the flow. Throughput (C) is less critical for voice as calls consume very little bandwidth (e.g., 64-100 Kbps), making congestion (loss/jitter) the primary enemy, not raw speed.

NEW QUESTION # 41
While designing a greenfield Prisma SD-WAN solution for a retailer, the risk management group requires segmentation of the retail network to avoid one large fault domain.
The following data points are provided:
* Two data centers and all sites need to access applications in both data centers
* 1000 retail branches with stores concentrated in multiple metropolitan areas
* Data Center 1 and Data Center 2 have different sets of applications that are not replicated
* Maintaining application availability is the primary goal
Which action will segment the retail network and reduce regional outages?

• A. Create more than one data center cluster for a larger pool of resources and resiliency.
• B. Implement a single, large data center cluster spanning both data centers to centralize management and optimize resource use.
• C. Add more data center aggregation devices within the same cluster to enhance the scalability and resilience.
• D. Create more than one data center cluster in each data center and assign sites to clusters so nearby retail locations can be spread on separate clusters.

Answer: D

Explanation:
In large-scale Prisma SD-WAN deployments, such as a retail network with 1,000 branches, architectural resilience is achieved through a strategy known as Hub Clustering. A Data Center Cluster is a logical grouping of ION devices at a hub site that provides termination for branch-to-DC VPN tunnels. To prevent the creation of a massive, single fault domain, Palo Alto Networks best practices recommend segmenting the branch population across multiple clusters.
By creating more than one data center cluster in each data center and strategically assigning sites to these clusters, an administrator can effectively isolate failure events. In a metropolitan area where stores are concentrated, spreading nearby retail locations across different clusters ensures that a localized resource failure or a cluster-specific misconfiguration only impacts a subset of the stores in that region rather than causing a complete regional outage.
This design directly addresses the requirement for maintaining application availability. Since Data Center 1 and Data Center 2 host different applications, each branch site must maintain active paths to both DCs. By using multiple clusters at each DC, the risk management group's goal of avoiding a large fault domain is met through "blast radius" containment. If Cluster A at Data Center 1 fails, the 1,000 sites are not all affected simultaneously; instead, only the specific sites bound to Cluster A lose connectivity to that hub, while their neighbors bound to Cluster B remain functional. This approach provides the highest level of regional resiliency and operational stability for high-density retail environments.

NEW QUESTION # 42
When integrating Prisma SD-WAN with Prisma Access, what is the specific role of the Service Connection (SC)?

• A. It is the peering link between different Prisma Access regions to optimize global traffic.
• B. It is the IPSec tunnel that connects a Branch site to the Prisma Access gateway for internet access.
• C. It connects the Prisma Access cloud infrastructure back to the customer's Headquarters or Data Center for access to internal private resources (e.g., AD, DNS, Intranet).
• D. It is the SSL VPN portal used by mobile users to connect to the network.

Answer: C

Explanation:
Comprehensive and Detailed Explanation
In the Prisma Access architecture (integrated with SD-WAN), distinct connection types serve different purposes.
Remote Networks: These are the connections from your Branch sites (using ION devices) into the cloud. They allow branches to get to the internet or other branches.
Service Connections (SC): This is a specialized high-bandwidth connection used to bridge the Prisma Access Cloud to your Private Data Center or Headquarters.
The primary use case for a Service Connection (Option A) is to allow mobile users and branch users (who are connected to the Prisma cloud) to reach private, centralized resources that still reside on-premise, such as Active Directory controllers, legacy databases, or mainframes. Without a Service Connection, users in the cloud would be able to reach the internet and each other, but not the servers physically located in your HQ data center. The CloudBlade automates the creation of these tunnels, but architecturally, the "Service Connection" is the "cloud-to-HQ" bridge.
