Exam N10-008 topic 1 question 84 discussion

The devil is in the details, the question is essentially asking, why would it be possible for an individual to use a card reader, that would be a access control vestibule or mantrap. An individual would typically utilize a card reader if you want to access a particular room via a mantrap.

This was a throwaway. Cameras dont even make use of a card reader

Access control vestibules can ensure that each individual's entry into the datacenter is separately recorded by a card reader, even when multiple employees enter the facility at the same time. Access control vestibules are small rooms with two doors that require authorized individuals to present their access cards to enter or exit. The vestibules ensure that only authorized individuals enter the datacenter, and their entry is individually recorded by the card reader. Once the first door is closed, the employee must present their card again to enter the second door. This double-entry system ensures that access to the datacenter is controlled and recorded accurately.

This is very clearly B, a vestibule throttles a group so one can enter at a time, in this case requiring a card reader swipe between each person's access. It is not D. Cameras documenting who is entering would require analytics, which are fallible, and while you may have footage recorded for later review, this question specifically says the record is created by a card reader.

Also a smart locker is where you could store your cell phone or other personal items in a secure facility that doesn't allow external electronic devices

Card readers record who swipes their badge using an access control system. Each badge is assigned to an individual in said system. An access control vestibule would enforce each person having to swipe their card. Camera would not enforce badge swiping it just passively records

Cameras are the only device that allows to record

While this question should be worded a little differently Access Control vestibules would be the best answer: As it relates to security, vestibules are often paired with a check-in window and used to ensure individuals have the proper credentials or identification before they pass on to the next area.

I would say smart locker while access control vestibules is a new name for mantrap
