Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 183

After the rogue reports from Cisco Prime Infrastructure are reviewed, it is determined that the automatic rogue mitigation is not working as planned. Which security measure must be taken to help prevent rogue APs from being plugged into the network?

Answer options

• A. Apply port security to the switch.
• B. Add a MAC filter to the switch.
• C. Apply a different version of spanning tree.
• D. Apply an IP access list to ports.

Correct answer: A

Explanation

Implementing port security on the switch allows you to restrict the devices that can connect to the network by limiting the number of MAC addresses allowed on a port. This directly helps prevent rogue APs from being connected. The other options, while providing some level of security, do not specifically address the prevention of unauthorized access points in the same effective manner.
