Which of the following is a high-security installation that requires visual identification, as well as authentication, to gain access?
a. Mantrap
b. Fencing
c. Proximity reader
d. Hot aisle
Answer: A
High-security installations use a type of intermediate access control mechanism called a mantrap. Mantraps require visual identification, as well as authentication, to gain access. A mantrap makes it difficult for a facility to be accessed in number because it allows only one or two people into the facility at a time.
