CompTIA Security+ (SY0-601) — Question 13

A technician was dispatched to complete repairs on a server in a data center. While locating the server, the technician entered a restricted area without authorization. Which of the following security controls would BEST prevent this in the future?

Answer options

• A. Use appropriate signage to mark all areas.
• B. Utilize cameras monitored by guards.
• C. Implement access control vestibules.
• D. Enforce escorts to monitor all visitors.

Correct answer: C

Explanation

Implementing access control vestibules is the most effective method as they physically restrict entry to authorized personnel only. While signage and monitored cameras can help, they do not prevent unauthorized access as effectively as a physical barrier. Enforcing escorts can be useful but is less practical for ongoing operations compared to access control vestibules.
