NEW QUESTION # 13
You are a security administrator for your company's Oracle Cloud Infrastructure (OCI) tenancy. Your storage administrator informs you that she cannot associate an encryption key from an existing Vault to a new Object Storage bucket.
What could be a possible reason for this behavior?
- A. The secret for the key was not created beforehand
- B. There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key.
- C. The Object Storage bucket policy lacks the necessary Access Control List (ACL).
- D. The storage administrator forgot to select "Encrypt using Oracle managed keys" while creating the bucket.
Answer: B
Explanation:
There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key. The explanation is that when you create an Object Storage bucket with encryption using a customer-managed key from Vault, you need to have an IAM policy that allows the Object Storage service to use the key on your behalf. The policy should look like this:
allow service objectstorage-<region> to use key in compartment <compartment-name> where <region> is the region where your bucket resides and <compartment-name> is the compartment where your key resides.

- E. Creating and managing WAF rules
- F. Viewing all zones
Answer: A,B,F
Explanation:
Explanation
Creating and managing records, creating and managing zones, and viewing all zones are three capabilities that are available with the OCI DNS service. Records are data elements that map domain names to IP addresses or other information. Zones are collections of records that correspond to a domain name or a subdomain name.
The OCI DNS service allows users to create and manage records and zones for their domains or subdomains, as well as view all zones in their tenancy. The other options are not capabilities of the OCI DNS service, but of other OCI services such as WAF, IAM, and Networking. References: [DNS Service], [Records], [Zones]
NEW QUESTION # 15
As a network architect you have deployed a public subnet on your Virtual Cloud Network (VCN) with this security list:
You have also created a network security group (NSG) as shown in the table here, and assigned it to your bastion host:
You have confirmed that routing is correct but when you SSH to the VM from your home over the Internet you are unable to connect.
What could be the problem?
- A. Internet traffic should be allowed only on the NSG.
- B. User will be able to SSH to the VM from the Internet as SSH is open on the NSG.
- C. SSH traffic is not allowed in the security list nor on the NSG from the Internet.
- D. Public subnet does not have a route rule to the Internet Gateway.
Answer: C
Explanation:
SSH traffic is not allowed in the security list nor on the NSG from the Internet is the correct answer. This is because the security list only allows ingress traffic from 10.0.0.24 on port 22, and the NSG only allows ingress traffic from 10.0.0.0/16 on port 22. Neither of them allows ingress traffic from 0.0.0.0/0 (the Internet) on port 22, which is required for SSH access. The other options are not correct, as they do not explain why SSH access is not possible. Reference: [Security Lists], [Network Security Groups]
NEW QUESTION # 16
In which two ways can Oracle Security Zones assist with the cloud security shared responsibility model?
- A. Deny public access to Oracle Cloud Infrastructure resources, such as databases and object storage buckets.
- B. Encrypt storage resources with a customer-managed key.
- C. Add or move a standard compartment to a highly secured security zone compartment.
- D. Allow access to an unsecured compartment, which is moved from a standard compartment.
Answer: A,B
Explanation:
Oracle Security Zones is a service that helps you enforce best practices and prevent misconfigurations on your OCI resources by applying predefined policies and controls. Some of the benefits of using Security Zones are:
Encrypt storage resources with a customer-managed key: Security Zones require that all storage resources, such as block volumes, boot volumes, file systems, and object storage buckets, are encrypted with a customer-managed key from Vault. This ensures that you have full control over the encryption and decryption of your data at rest.
Deny public access to OCI resources, such as databases and object storage buckets: Security Zones prevent you from creating or updating OCI resources that have public access enabled, such as databases and object storage buckets that are accessible from the internet. This reduces the risk of unauthorized access or data leakage.

NEW QUESTION # 19
You want to create a policy to allow the NetworkAdmins group to manage Virtual Cloud Network (VCN) in compartment C. You want to attach this policy to the tenancy. The compartment hierarchy is shown below.
Which policy statement can be used to accomplish this task?
- A. Allow group NetworkAdmins to manage virtual-network-family in tenancy
- B. Allow group NetworkAdmins to manage virtual-network-family in compartment B:C
- C. Allow group NetworkAdmins to manage virtual-network-family in compartment C
- D. Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C
Answer: D
Explanation:
Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C. The explanation is that when you attach a policy to the tenancy, you need to specify the full path of the compartment where you want to grant permissions. In this case, the compartment C is a sub-compartment of compartment B, which is a sub-compartment of compartment A, which is a sub-compartment of the root compartment (tenancy). Therefore, the full path of compartment C is A:B:C. The virtual-network-family resource type includes all the resources related to VCN, such as subnets, route tables, security lists, gateways, etc.

NEW QUESTION # 23
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
- A. Each VNIC can only have one private IP address.
- B. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
- C. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
- D. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
Answer: B,D
Explanation:
Explanation
By default, the primary VNIC of an instance in a subnet has one primary private IP address. A private IP can have an optional public IP assigned to it if it resides in a public subnet. The explanation is that a private IP address is an IPv4 address that is assigned to a VNIC and belongs to the CIDR block of the VCN or subnet.
By default, the primary VNIC of an instance in a subnet has one primary private IP address, which is automatically assigned by OCI and cannot be changed. However, you can also assign secondary private IP addresses to a VNIC, either manually or automatically, up to a maximum of 31 per VNIC. A private IP address can have an optional public IP address assigned to it, which allows the instance to communicate with the internet. A public IP address can be either ephemeral or reserved, depending on whether you want to keep it after stopping or terminating the instance. A private IP address can only have a public IP address assigned to it if it resides in a public subnet, which means that the subnet's route table has a route rule that directs traffic to the internet gateway.

Which is NOT a valid option for an Oracle Cloud Infrastructure (OCI) compute shape?
- A. Bare Metal
- B. Exadata Virtual Machine
- C. Dedicated Virtual Machine Host
- D. Virtual Machine
Answer: B
Explanation:
Explanation
Exadata Virtual Machine is not a valid option for an OCI compute shape. Exadata Virtual Machine is a deployment option for Exadata Cloud Service or Exadata Cloud@Customer, which are services that provide dedicated Exadata infrastructure for running Oracle databases in OCI. Exadata Virtual Machine allows you to create multiple virtual machines on each Exadata compute node and isolate them from each other using Oracle VM technology. The valid options for OCI compute shapes are:
Bare Metal: A bare metal instance is a physical server that gives you direct access to the underlying hardware and full isolation from other tenants.
Dedicated Virtual Machine Host: A dedicated virtual machine host is a physical server that hosts only your virtual machine instances and no other tenant's instances.
Virtual Machine: A virtual machine instance is a virtual server that runs on a shared physical server with other tenants' instances.
Burstable: A burstable instance is a virtual machine instance that has a baseline utilization of either 12% or 50% of each CPU core and can burst above the baseline when needed.
NEW QUESTION # 26
You have a high-demand web application running on Oracle Cloud Infrastructure (OCI). Your tenancy administrator has set up a schedule-based autoscaling policy on instance pool withan initial size of 5 instancesfor the application.
Policy 1:
Target pool size:10 instances
Execution time:8:30 a.m. on every Monday through Friday, in every month, in every year Cron expression:0 30 8 ? * MON-FRI * Which statement accurately explains the goal of this policy?
- A. Goal: A one-time schedule with only one scaling out event. At 8:30 a.m., on December 31, 2021, scale theinstance pool to 10 instances from 5.
- B. Goal: A recurring weekly schedule. On all days of the week at 8.30 a.m., scale out the pool to 10 instancesfrom the initial size of 5
- C. Goal: A recurring monthly schedule. On all days of the month, set the initial pool size to 5 instances. At
8.30 a.m., on every day of the month, scale out to 10 instances. - D. Goal: A recurring daily schedule. On weekday mornings at 8.30 a.m., scale out to 10 instances.
Answer: D
Explanation:
Explanation
The explanation is that a schedule-based autoscaling policy allows you to adjust the size of your instance pool based on a cron expression that specifies the date and time of the scaling action. The cron expression consists of six fields: seconds, minutes, hours, day of month, month, and day of week. In this case, the cron expression is 0 30 8 ? * MON-FRI *, which means that the scaling action will occur at 8:30 a.m. on every Monday through Friday, regardless of the day of month or month. Therefore, the goal of this policy is to scale out the instance pool to 10 instances on weekday mornings at 8:30 a.m.

NEW QUESTION # 32
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges.
- B. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- C. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
- D. Private subnets should ideally have individual route tables to control the flow of traffic within and outside of VCN.
Answer: A
Explanation:
Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization's private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.
NEW QUESTION # 33
You are using the Oracle Cloud Infrastructure (OCI) Vault service to create and manage Secrets. For your database password, you have created a secret and rotated the secret one time. The secret versions are as follows:
-----------------------------------------
2 (latest) | Current
1 | Previous
You later realize that you have made a mistake in updating the secret content for version 2 and want to rollback to version 1.
What should you do to rollback to version 1?
- A. Deprecate version 2 (latest). Create new Secret version 3. Create soft link from version 3 to version 1.
- B. From the version 1 menu on the OCI console, select "Promote to Current".
- C. From the version 2 (latest) menu, select "Rollback" and select version 1 when given the option.
- D. Create a new secret version 3 and set to Pending. Copy the content of version 1 into version 3.
