CompTIA Network+ (N10-008) — Question 270

A company is utilizing multifactor authentication for data center access. Which of the following is the MOST effective security mechanism against physical intrusions due to stolen credentials?

Answer options

Correct answer: A

Explanation

Biometrics security hardware is the most effective mechanism because it requires unique physical traits of the user, making it difficult for an intruder to gain access with stolen credentials. In contrast, access card readers and access control vestibules can be bypassed if someone has the correct card, and motion detection cameras merely record activities without preventing unauthorized access.
