Exam 300-430 topic 1 question 248 discussion

To allow multiple mDNS (multicast DNS) profiles based on a user authentication profile configured in Cisco ISE, the AAA Override setting must be enabled on the WLAN. This allows the WLC to apply specific mDNS profiles based on the attributes (such as user roles or profiles) sent by Cisco ISE during the authentication process. Explanation of the options: A. AAA Override: This is correct. Enabling AAA Override allows the WLC to apply attributes (such as mDNS profiles) sent by Cisco ISE during user authentication. B. service advertisement: This is not relevant to mDNS profiles or AAA Override. It is used for advertising services like Bonjour. C. mDNS policy: While mDNS policies are used to define how mDNS traffic is handled, they are not directly tied to user authentication profiles from Cisco ISE. D. mDNS Snooping: This feature enables the WLC to inspect and forward mDNS traffic but does not allow for multiple mDNS profiles based on user authentication.

Step 8 The administrator can also create multiple mDNS profiles on the WLC and override them based on user authentication. The mDNS profile can be user specific and be overridden with AAA “av-pair=mDNS-profile-name” returned to WLC from AAA server that overrides default profile. https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-0/WLAN-Bonjour-DG.html
