Question
A WLC must be configured to allow multiple mDNS profiles based on a user authentication profile configured in Cisco ISE. Which WLAN setting must be configured?
Options
- AAAA Override
- Bservice advertisement
- CmDNS policy
- DmDNS Snooping
Explanation
AAA Override on a WLAN enables Cisco ISE to dynamically push RADIUS attributes - including mDNS profile assignments - to the WLC after a user authenticates, allowing per-user mDNS policy enforcement.
Common mistakes.
- B. Service advertisement configures which mDNS services the controller advertises or forwards, but does not enable ISE to dynamically assign different mDNS profiles per authenticated user.
- C. The mDNS policy setting defines the policy itself on the WLC, but enabling it alone does not allow ISE to override it dynamically based on per-user authentication results.
- D. mDNS Snooping enables the WLC to listen to and cache mDNS service announcements from the wired network, but does not provide the mechanism for ISE to assign per-user mDNS profiles.
Concept tested. AAA Override for dynamic mDNS profile assignment via ISE
