which of the following?

Examples of types of physical access controls include all except which of the following?

A.
badges

B.
locks

C.
guards

D.
passwords

Explanation:
A password is not a physical thing, it’s a logical one. You can control physical

access with armed guards, by locking doors and using badges to open doors, but you can’t relate
password to a physical environment. Just to remember, Passwords are used to verify that the user
of an ID is the owner of the ID. The ID-password combination is unique to each user and therefore
provides a means of holding users accountable for their activity on the system. They are related to
software, not to hardware.
