Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 55

A network engineer observes a spike in controller CPU overhead and overall network utilization after multicast is enabled on a controller with 500 APs. Which feature corrects the issue?

Answer options

• A. controller IGMP snooping
• B. multicast AP multicast mode
• C. broadcast forwarding
• D. unicast AP multicast mode

Correct answer: B
