Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 224

An engineer designs a new wireless network that uses a Cisco Catalyst 9800 Series wireless controller. The controller must be in a DMZ. The internal network is to be at the main on-premises data center of the customer. In addition, the customer wants to establish an EoIP tunnel to a Cisco 5520 WLC that is in a regional office. How must this requirement be incorporated into the design?

Answer options

• A. Use Cisco IOS-XE code that supports encryption of the data plane on the Catalyst 9800 WLC.
• B. Use AirOS code that supports encryption of the control plane on the 5520 WLC.
• C. Use Cisco IOS-XE code that supports encryption of the control plane on the Catalyst 9800 WLC.
• D. Use AirOS code that supports encryption of the data plane on the 5520 WLC.

Correct answer: B

Explanation

The correct answer is B because AirOS is the appropriate software for the 5520 WLC to ensure encryption of the control plane, satisfying the requirement for secure communication. The other options incorrectly specify software or encryption types that do not match the needs of the architecture or the capabilities of the devices mentioned.
