CompTIA CV0-003 CompTIA Cloud+ Certification Exam Practice Test

Answer : D

1. Understanding the Logs and Issue:

Log behavior:

The scheduled tasks (e.g., data extraction) run successfully at first but fail after a certain number of executions.

The issue resets after 24 hours, suggesting a time-based restriction or limitation.

Key log entries:

At 1:30 and 1:45, 'Data Extract, Failed' occurs repeatedly.

At 2:05, 'Access, Denied' is logged, indicating a lack of access during subsequent operations.

2. Analyzing the Options:

A . Insufficient permissions:

Incorrect. Permissions issues would likely prevent tasks from succeeding at any point, but the logs show initial successes before failures.

B . Vendor lock-in:

Incorrect. Vendor lock-in refers to dependency on a specific cloud provider and is unrelated to the observed log behavior.

C . Insufficient capacity:

Incorrect. Capacity issues would lead to failures related to resource allocation (e.g., memory, CPU) but would not reset every 24 hours.

D . API limits:

Correct. Many cloud platforms enforce API rate limits or quotas, which restrict the number of API calls within a given time frame (e.g., per hour or day). The issue resetting every 24 hours strongly suggests hitting daily API call limits.

E . Licensing issues:

Incorrect. Licensing issues would typically manifest as a permanent or recurring access denial, not resetting on a daily basis.

3. Why API Limits is the Best

Cloud platforms often enforce API limits to prevent overuse or abuse.

Once the quota is exceeded, further API calls (e.g., 'Data Extract') fail until the limit resets, typically on a daily basis.

The pattern of success followed by failure aligns perfectly with hitting an API limit.

4. Resolution:

Review API call quotas with the cloud service provider.

Optimize or batch API calls to reduce frequency.

Upgrade the subscription plan to increase API limits if necessary.

Answer : D

1. Understanding the Options:

Predeveloped AI/ML solutions are turnkey tools that address specific AI tasks like image recognition, video analysis, and natural language processing (NLP).

2. Analyzing the Options:

A . Natural language processing, forecasting, and VoIP:

Incorrect. VoIP is not an AI/ML solution; it is a telecommunication technology.

B . Serverless application, image recognition, and speech recognition:

Incorrect. Serverless applications are related to cloud computing architectures, not AI/ML solutions.

C . Code review, anomaly detection, and elasticity:

Incorrect. While anomaly detection is an AI/ML solution, elasticity refers to cloud resource scaling and is unrelated to AI.

D . Image recognition, video analysis, and natural language processing:

Correct. These are classic examples of predeveloped AI/ML solutions.

3. Predeveloped AI/ML Solution Examples:

Image recognition: Recognizes objects or patterns in images.

Video analysis: Processes and analyzes video content for insights.

Natural language processing: Enables machines to interpret and respond to human language.

Answer : B

1. Understanding the Issue:

A non-supported Linux version indicates an issue with the configuration or template used during provisioning.

Automation scripts work correctly, so the problem likely lies upstream in the provisioning setup.

2. Analyzing the Options:

A . Provisioning script indentation:

Incorrect. Indentation issues typically result in syntax errors, not incorrect Linux versions.

B . Template selection:

Correct. Incorrect or outdated templates can provision servers with unsupported configurations or OS versions.

C . API version:

Incorrect. API versioning is related to compatibility with cloud services but is unlikely to affect the OS version on a server.

D . Script account:

Incorrect. The account running the script has no direct impact on the OS version of the provisioned server.

3. Why Template Selection is Key:

Templates define the OS, version, and configurations for provisioned instances.

Reviewing the selected template ensures it aligns with the organization's standards.

Answer : C

1. Understanding the Requirement:

The goal is to make container images available for mass deployment securely.

The solution should support containerized environments like Kubernetes or Docker.

2. Analyzing the Options:

A . Encrypted block storage:

Incorrect. Block storage is suitable for raw data or volumes but does not provide the functionalities needed for managing or deploying container images.

B . CIFS share:

Incorrect. CIFS is used for file sharing across networks but lacks security and deployment features specific to container images.

C . Private registry:

Correct. A private registry, such as Docker Hub or Harbor, securely stores and distributes container images for mass deployment.

D . Source control management:

Incorrect. Tools like Git manage source code, not container images.

3. Why Private Registry is Ideal:

Allows secure access control for container images.

Integrates seamlessly with deployment tools and orchestration platforms like Kubernetes.

Answer : A

1. Requirements Analysis:

Subnet size (/24): Allows 23224=2562^{32 - 24} = 25623224=256 IPs.

Servers requiring isolation: Development servers and VDI servers.

Web, application, and database servers can share subnets.

2. Option Analysis:

A . Correct.

VDI: /25 (128 IPs): Adequate for 100 virtual desktops.

Web, application, and database: /26 (64 IPs): Fits 10 + 10 + 10 = 30 servers.

Development: /27 (32 IPs): Fits 15 development servers.

VDI servers: /28 (16 IPs): Fits 7 VDI servers.

B . Same as A. Correct.

C . Incorrect.

Web, application, and database: /27 (32 IPs): Insufficient for 30 servers.

D . Incorrect.

Allocates excessive IPs to each subnet (e.g., 64 IPs for VDI servers with only 7 devices).

3. Final Decision:

Option A (or B) optimally divides the /24 subnet without wasting IPs and meets all isolation requirements.
