Important CompTIA CV0-004 Exam Questions

Answer: B

Explanation:

The nature of the local storage in a video surveillance system that records road incidents and stores the videos locally before uploading them to the cloud and deleting them from local storage is ephemeral. Ephemeral storage is temporary and is designed to provide short-term storage for information that changes frequently or is not meant to be persistent.

Answer: A

Explanation:

The canary deployment model is an approach where a new feature or service is rolled out to a small subset of users before being deployed widely. This method allows the company to test the impact of the new feature in the production environment with a limited scope, minimizing risk and potential cost implications if issues arise. This approach contrasts with blue-green deployments, which involve switching between two identical environments; rolling deployments, which gradually update all instances; and in-place deployments, which update the current environment. The canary model is particularly suited for targeting specific user groups and gathering feedback before a full rollout.

Answer: C

Explanation:

For long-term reporting purposes, the most critical aspect to consider is the retention period of the backups. This is because the bank will likely require access to historical data for audit, compliance, and reporting purposes. The retention policy will need to ensure that backups are kept for the required duration, which may be several years depending on regulatory and business needs. Adjusting the retention policy will help ensure that the necessary data is preserved for as long as it is needed, without unnecessary data accumulation that could lead to higher costs and management complexity.

Answer: C

Explanation:

The most likely reason for the script creating virtual machines without tags, despite working in the past, is command deprecation. Cloud service providers update their APIs and CLI commands over time, and a previously used command to tag resources might no longer be valid.

: Understanding cloud service APIs and the importance of keeping up with updates is part of cloud technical operations covered in CompTIA Cloud+.

After applying an update---even if it ''appears'' successful---the next step is validation. In CompTIA Cloud+ (CV0-004) operational procedures, change management and maintenance activities require post-change verification to confirm the service is functioning as intended and that no regressions were introduced. For a code repository running on a VM, this includes confirming the repository service starts correctly, users can authenticate, read/write operations work, hooks/integrations function, and logs show no errors. This step also supports incident prevention and rapid rollback decision-making if issues are detected.

Option A (Back up the repository) is typically performed before making changes to protect against failed updates. Option C (Restore the repository) is only appropriate if testing reveals a failure or corruption and recovery is needed. Option B (Decommission the repository) is unrelated to a routine upgrade. Therefore, the most correct immediate action after the update is to test repository functionality to ensure availability, integrity, and expected operational behavior.
