Deploying Cisco Wireless Enterprise Networks (WIDEPLOY, legacy) — Question 5

A network engineer observes a spike in controller CPU overhead and overall network utilization after enabling multicast on a controller with 500 APs. What feature is necessary to correct the issue?

Answer options

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

Correct answer: B

Explanation

The correct answer, unicast AP Multicast Mode, helps to reduce the burden on the network by sending multicast traffic as unicast to each AP, which alleviates CPU overhead. The other options do not specifically address the need to manage multicast traffic efficiently in a large deployment, making them less suitable for resolving the observed issue.
