CompTIA Network+ (N10-008) — Question 452

A technician is concerned about unauthorized personnel moving assets that are installed in a data center server rack. The technician installs a networked sensor that sends an alert when the server rack door is opened. Which of the following did the technician install?

Answer options

Correct answer: D

Explanation

The technician installed a tamper detection sensor, which is specifically designed to alert when unauthorized access occurs, such as when a door is opened. The other options do not serve the same purpose; a cipher lock controls access without alerting, asset tags are for tracking items, and an access control vestibule is a physical barrier rather than a detection mechanism.
