Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 163
A customer has a Cisco wireless network that has these configurations and components:
• two Cisco Catalyst 9800 Series WLCs in a high availability cluster
• 50 Cisco 2800I APs
• all SSIDs and services are 5 GHz only
A security mandate requires that rogue APs be scanned and identified in 2.4 GHz and 5 GHz bands and must not impact existing client connectivity. How must the wireless network be reconfigured to meet the requirement without purchasing additional APs?
Answer options
- A. Set the XOR radio role to Client Serving and the slot 1 radio to Sniffer mode on all the APs.
- B. Set the XOR radio role to Monitor mode and the slot 1 radio to Client Serving on all the APs.
- C. Set the XOR radio role to Client Serving and the slot 1 radio to Monitor mode on all the APs.
- D. Set the XOR radio role to Sniffer mode and the slot 1 radio to Client Serving on all the APs.
Correct answer: B
Explanation
The correct answer is B because setting the XOR radio role to Monitor mode allows for the detection of rogue APs in both frequency bands without interfering with client connectivity, which is maintained by the slot 1 radio set to Client Serving. Options A, C, and D do not meet the requirement for monitoring in both bands or may disrupt client connections.
