CompTIA CySA+ (CS0-003) — Question 344

After updating the email client to the latest patch, only about 15% of the workforce is able to use email. Windows 10 users do not experience issues, but Windows 11 users have constant issues. Which of the following did the change management team fail to do?

Answer options

• A. Implementation
• B. Testing
• C. Rollback
• D. Validation

Correct answer: B

Explanation

The correct answer is B, as it indicates that the change management team likely did not adequately test the email client after the update, leading to issues for Windows 11 users. Options A, C, and D are incorrect because the implementation and rollback of the patch may have been completed successfully, and validation is a different process that occurs after testing.
