CompTIA Network+ (N10-008) — Question 118

A network switch was installed to provide connectivity to cameras monitoring wildlife in a remote location. The organization is concerned that intruders could potentially leverage unattended equipment in the remote location to connect rogue devices and gain access to the organization's resources. Which of the following techniques would BEST address the concern?

Answer options

• A. Configure port security using MAC filtering.
• B. Manually register the cameras on the switch address table.
• C. Activate PoE+ on the active switchports.
• D. Disable Neighbor Discovery Protocol on the switch.

Correct answer: A

Explanation

Configuring port security using MAC filtering is the best approach as it restricts which devices can connect to the switch based on their MAC addresses, effectively preventing unauthorized access. Manually registering the cameras is less effective since it doesn't prevent rogue devices from connecting. Activating PoE+ does not address security concerns, and disabling Neighbor Discovery Protocol does not prevent rogue devices from connecting either.
