Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 158

A new wireless network design has these requirements:
• AireOS WLCs as guest anchors
• a Cisco Catalyst 9800 Series WLC as the foreign controller
• use of Wi-Fi 6 APs
• inter-controller roaming for guest users

Which two design approaches meet these requirements? (Choose two.)

Answer options

• A. Use EoIP for communication between controllers.
• B. Use WLC software versions that support IRCM.
• C. Use AVC on the anchor WLCs.
• D. Use IPv6 across the wireless network.
• E. Use secure mobility to pair controllers.

Correct answer: B, E

Explanation

The correct answers, B and E, are valid because B specifies the use of WLC software versions that support Inter-RF Domain Handover (IRCM), essential for seamless guest roaming. E emphasizes the importance of secure mobility for pairing controllers, which is crucial for maintaining guest user sessions across different controllers. Options A, C, and D do not directly relate to the requirements for guest user roaming and network architecture specified in the question.
