Answer: C

Explanation:

Badge readers are used to implement secure physical access to a data center. They are used to read the identification information on an employee’s badge and grant access to the data center if the employee is authorized2.

This system requires individuals to have an access badge that contains their identification information or a unique code that can be scanned by a reader. After the badge is scanned, the system compares the information on the badge with the authorized personnel database to authenticate if the individual has the required clearance to enter that area. The other options listed, such as a geofence, alarm system, or motion sensor are security measures that may be used in conjunction with badge readers, but do not provide identification and authentication features.
