Which of the following would be the MOST appropriate physical security solution for the main entrance to a
data center”?

A.
Mantrap

B.
Biometric lock

C.
Closed-circuit television (CCTV)

D.
Security guard

Explanation:

A biometric device will ensure that only the authorized user can access the data center. A mantrap, by itself,
would not be effective. Closed-circuit television (CCTV) and a security guard provide a detective control, but would not be as effective in authenticating the access rights of each individual.
