Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 84

A network engineer is troubleshooting connectivity issues between two WLCs running 8.x code in SSO mode and finds that the redundancy management heartbeat is failing. Which packet type must be filtered for heartbeats when taking a capture to verify communication?

Answer options

• A. RSTP
• B. UDP
• C. TCP
• D. ICMP

Correct answer: B

Explanation

The correct answer is B, UDP, because the redundancy management heartbeats between WLCs are sent using UDP packets. The other options, RSTP, TCP, and ICMP, do not pertain to the specific packet type used for redundancy heartbeats, making them irrelevant for this troubleshooting scenario.
