NEW QUESTION # 33
A company's website suddenly crashed. A cloud engineer investigates the following logs:
Which of the following is the most likely cause of the issue?
- A. Leaked credentials
- B. DDoS
- C. Cross-site scripting
- D. SQL injection
Answer: B
Explanation:
The logs indicate a sudden surge in access requests to the website's homepage, followed by 502 errors, which are indicative of server overload or failure to handle incoming requests. This pattern is typical of a Distributed Denial of Service (DDoS) attack, where multiple compromised systems flood the target with traffic, exceeding its capacity to handle requests, leading to service disruption.

- A. PaaS
- B. laaS
- C. SaaS
- D. DBaaS
Answer: B
Explanation:
For testing the scalability of an in-house-developed software that requires a cluster of 100 or more servers, Infrastructure as a Service (IaaS) is the best model. IaaS provides the necessary compute resources and allows the engineering department to configure the environment as needed for their specific test without the constraints that might be present in PaaS or SaaS offerings.
NEW QUESTION # 35
A systems administrator is provisioning VMs according to the following requirements:
- A VM instance needs to be present in at least two data centers.
- During replication, the application hosted on the VM tolerates a
maximum latency of one second.
- When a VM is unavailable, failover must be immediate.
Which of the following replication methods will best meet these requirements?
- A. Point-in-time
- B. Snapshot
- C. Live
- D. Transactional
Answer: C
Explanation:
Live replication is the process of continuously copying data in real-time to ensure that an exact copy is available in another location. Given the requirement for immediate failover and the presence of the VM instance in at least two data centers, live replication is the best method to meet the one-second maximum latency tolerance and ensure immediate availability in the event of a VM becoming unavailable.

Snapshots capture the state of a storage volume at a point in time and can be used to restore data quickly with minimal administrative overhead.References: Data protection strategies like volume snapshots are discussed under cloud data management and protection in the CompTIA Cloud+ objectives.
NEW QUESTION # 38
The company's IDS has reported an anomaly. The cloud engineer remotely accesses the cloud instance, runs a command, and receives the following information:
Which of the following is the most likely root cause of this anomaly?
- A. Leaked credentials
- B. Privilege escalation
- C. Defaced website
- D. Cryptojacking
Answer: B
Explanation:
The output from the 'ps' command indicates there is a process running under the UID (User ID) of
0, which is the root user, and the command that was run is '/var/www/command.py'. Given that the normal Apache processes are running under their own UID (65535), this suggests that a command was executed with root privileges that typically should not have such high-level access.
This is a strong indicator of privilege escalation, where an unauthorized user or process gains elevated access to resources that are normally protected from an application or user.
NEW QUESTION # 39
Which of the following can reduce the risk of CI/CD pipelines leaking secrets?
- A. Protected Git branches
- B. Canary tests
- C. Use of a VM instead of containers
- D. Private image repositories
Answer: A
Explanation:
Protected Git branches help reduce the risk of CI/CD pipelines leaking secrets by imposing restrictions on who can commit to the branches, enforce status checks before merging, and prevent unauthorized access or changes to sensitive information, such as API keys, passwords, and secret tokens. This ensures that only approved changes can be made to the codebase, and sensitive information is safeguarded.
NEW QUESTION # 40
Which of the following is the most cost-effective way to store data that is infrequently accessed?
- A. Off-site
- B. Hot site
- C. Cold site
- D. Warm site
Answer: A
Explanation:
The most cost-effective way to store data that is infrequently accessed is typically an off-site storage service, often referred to as cold or archival storage. This type of storage is designed for data that is rarely accessed, providing lower storage costs.
Reference: Data storage solutions and their cost implications, including off-site (cold or archival) storage for infrequently accessed data, are part of the cloud storage options discussed in CompTIA Cloud+.

A cloud engineer is deploying a cloud solution that will be used on premises with need-to-know access. Which of the following cloud deployment models best meets this requirement?
- A. Public
- B. Community
- C. Hybrid
- D. Private
Answer: D
Explanation:
A private cloud deployment model is the most appropriate when the requirement is for 'need-to- know' access, as it offers a more secure environment with resources dedicated to a single organization. It can be hosted on-premises or off-premises but is maintained on a private network, ensuring greater control over the data, security, and compliance when compared to other cloud models.
NEW QUESTION # 43
Which of the following best explains the concept of migrating from on premises to the cloud?
- A. The creation of virtual instances in an external provider to transfer operations of selected servers into a new. remotely managed environment
- B. The physical transportation, installation, and configuration of company IT equipment in a cloud services provider's facility
- C. The configuration of a dedicated pipeline to transfer content to a remote location
- D. The extension of company IT infrastructure to a managed service provider
Answer: A
Explanation:
Migrating from on-premises to the cloud generally involves creating virtual instances in an external provider's environment and transferring the operations of selected servers to this new, remotely managed setup. This process allows organizations to leverage the cloud provider's resources and services.
Reference: The migration process and strategies are topics included in the Business Principles of Cloud Environments within the CompTIA Cloud+ curriculum.
NEW QUESTION # 44
A company is considering consolidating a number of physical machines into a virtual infrastructure that will be located at its main office. The company has the following requirements:
- High-performance VMs
- More secure
- Has system independence
Which of the following is the BEST platform for the company to use?
- A. Software application virtualization
- B. Type 1 hypervisor
- C. Remote dedicated hosting
- D. Type 2 hypervisor
Answer: B
Explanation:
Type 1 hypervisor would be the BEST platform for the company to use in this scenario. Type 1 hypervisors are native hypervisors that are installed directly on the host machine's hardware.
They provide high-performance virtualization, better security, and greater system independence, making them a better option than Type 2 hypervisors, software application virtualization, or remote dedicated hosting.
NEW QUESTION # 45
A cloud solutions architect needs to determine the best strategy to deploy an application environment in production, given the following requirements:
- No downtime
- Instant switch to a new version using traffic control for all users
Which of the following deployment strategies would be the BEST solution?
- A. Rolling
- B. Canary
- C. Hot site
- D. Blue-green
Answer: D
Explanation:
In a blue-green deployment, two identical environments are maintained, one for production (blue) and the other for the next version or release (green). All production traffic is initially directed to the blue environment, while the green environment is prepared and tested thoroughly without affecting the production environment. Once the green environment is ready, the traffic is switched instantly from the blue to the green environment using traffic control, with no downtime or impact on users.
NEW QUESTION # 46
A company hosts various containerized applications for business uses. A client reports that one of its routine business applications fails to load the web-based login prompt hosted in the company cloud.
Click on each device and resource. Review the configurations, logs, and characteristics of each node in the architecture to diagnose the issue. Then, make the necessary changes to the WAF configuration to remediate the issue.
Answer:
Explanation:
From the image, it's noticeable that some finance application rules are set to "Block" traffic. If the client's issue is with a finance-related application not loading the login prompt, these rules could be the cause.
The rule with ID 1005, labeled "Finance application 1", is configured to allow access to "webapp1" for finance-related paths. However, rule 1006, labeled "Finance application 2", is set to block access to "webapp1" for login-related paths.
To remediate the issue based on the WAF configuration you have provided, you would want to:
Ensure that the correct paths to the finance application are allowed through the WAF.
Modify any rules that are incorrectly blocking access to the application.
If the client's problem is specifically with the login prompt, then rule 1006 seems the most likely culprit. Changing the action from "Block" to "Allow" for rule 1006 could potentially resolve the client's issue. The rule should be carefully reviewed and updated to ensure legitimate traffic is not being blocked while still protecting against unauthorized access.
NEW QUESTION # 47

Which of the following steps should the security analyst take next to resolve this issue? (Select two).
- A. Contact John Smith and request the Ethernet cable attached to the desktop be unplugged
- B. Submit an IT support ticket and request Kali Linux be uninstalled from John Smith's computer
- C. Upgrade the Windows x64 operating system on John Smith's computer to the latest version.
- D. Check the running processes to confirm if a backdoor connection has been established.
- E. Block all outbound connections from the IP address 10.150.71.151.
- F. Block all inbound connections on port 4444 and block the IP address 201.101.25.121.
Answer: D,F
Explanation:
Given the suspicious activity and Kali Linux's association with penetration testing and hacking tools, the security analyst should block all inbound connections on port 4444, as it is commonly used for malicious purposes, and block the IP address that's potentially the source of the intrusion. Additionally, checking the running processes on John Smith's computer is crucial to determine if a backdoor or unauthorized connection has been established.
Reference: Incident response and threat mitigation steps such as these are part of the security protocols discussed in the CompTIA Cloud+ certification.
