CompTIA CySA+ (CS0-003) — Question 185

During the rollout of a patch to the production environment, it was discovered that required connections to remote systems are no longer possible. Which of the following steps would have most likely revealed this gap?

Answer options

• A. Implementation
• B. User acceptance testing
• C. Validation
• D. Rollback

Correct answer: C

Explanation

Validation is the process that ensures all systems function as intended after a patch is applied, making it the most likely step to reveal connection issues. Implementation focuses on applying the patch, while User acceptance testing is about end-user verification, and Rollback is related to reverting changes rather than identifying problems.
