CompTIA Cloud+ (CV0-004) — Question 30

A DevOps engineer is performing maintenance on the mail servers for a company’s web application. Part of this maintenance includes checking core operating system updates. The servers are currently running version 3.2 of the operating system. The engineer has two update options—one to version 4.1 and the other to version 3.7. Both versions are fully supported by the operating system manufacturer. Which of the following best describes the action the engineer should take?

Answer options

• A. Upgrade to 3.7 in the development environment.
• B. Upgrade to 4.1 on one production server at a time.
• C. Read the release notes on version 4.1
• D. Schedule a maintenance window and upgrade to 3.7 in the production environment.

Correct answer: C

Explanation

The correct answer is C, as reviewing the release notes for version 4.1 is crucial to understand new features, bug fixes, and any potential issues before proceeding with the upgrade. Options A and D suggest upgrading to version 3.7, which is not the best choice since the engineer has a newer version available. Option B implies a staggered upgrade to 4.1, but without prior knowledge of its implications from the release notes, this could be risky.
