CompTIA Security+ (SY0-501) — Question 85

The IT department is deploying new computers. To ease the transition, users will be allowed to access their old and new systems.
The help desk is receiving reports that users are experiencing the following error when attempting to log in to their previous system:

Logon Failure: Access Denied -
Which of the following can cause this issue?

Answer options

• A. Permission issues
• B. Access violations
• C. Certificate issues
• D. Misconfigured devices

Correct answer: C

Explanation

The correct answer is C, as certificate issues can lead to authentication problems when users attempt to access their previous system. Permission issues (A) and access violations (B) are less likely to cause a logon failure specifically related to certificate authentication, while misconfigured devices (D) typically wouldn't directly result in this specific error message.
