300-365 Question #178: Real Exam Question with Answer & Explanation

The correct answer is B: AAA override. On a Cisco WLC, AAA override takes the highest priority for interface and VLAN assignment, allowing RADIUS-returned attributes to supersede all locally configured settings including AP group assignments.

Question

An engineer deployed a high-density design in an auditorium with interface groups. A subgroup of users needs a different interface group than the general group. Which setting takes the highest priority on the WLC to use the correct group?

Options

ADHCP server override
BAAA override
CVLAN-ACL mapping
DAP group

Explanation

On a Cisco WLC, AAA override takes the highest priority for interface and VLAN assignment, allowing RADIUS-returned attributes to supersede all locally configured settings including AP group assignments.

Common mistakes.

A. DHCP server override changes only the DHCP server used for a client and does not affect interface group assignment, so it cannot redirect a user subgroup to a different interface.
C. VLAN-ACL mapping applies access control policies to a VLAN after assignment but does not override the interface group assigned to a client and has lower priority than AAA override.
D. AP group sets a default interface group for clients associating to APs in that group, but this local setting is overridden when the RADIUS server returns a different interface or VLAN attribute via AAA override.

Concept tested. Cisco WLC AAA override priority for interface group assignment
