CISSP Question #1239: Real Exam Question with Answer & Explanation

Question

In a DevOps environment, which of the following actions is MOST necessary to have confidence in the quality of the changes being made?

Options

• APrepare to take corrective actions quickly.
• BReceive approval from the change review board.
• CReview logs for any anomalies.
• DAutomate functionality testing.

Explanation

In DevOps, automated functionality testing is the cornerstone of maintaining confidence in code quality, enabling rapid, repeatable validation of changes throughout the pipeline.

Common mistakes.

• A. Preparing to take corrective actions quickly is a reactive measure that addresses problems after they occur, rather than proactively validating quality before or during the change process.
• B. Receiving approval from a change review board is a traditional ITIL/change management process that introduces manual gates and slows delivery, which is contrary to DevOps principles of continuous integration and delivery.
• C. Reviewing logs for anomalies is a post-deployment monitoring activity that detects issues after changes are already in production, rather than ensuring quality confidence during the development and release pipeline.
