300-365 Question #16: Real Exam Question with Answer & Explanation

The correct answer is C: interface groups. Interface groups on a Cisco WLC allow multiple VLAN interfaces to be bundled and assigned to a WLAN, providing control over which interfaces service specific SSIDs. This enables targeted interface selection when broadcasting an SSID across the wireless infrastructure.

Wireless Deployment

Question

A customer requires that an SSID is broadcasted to specific access points that use certain interfaces. Which feature can be used to achieve this goal?

Options

Amobility groups
Bflex-connect groups
Cinterface groups
DAP groups

Explanation

Interface groups on a Cisco WLC allow multiple VLAN interfaces to be bundled and assigned to a WLAN, providing control over which interfaces service specific SSIDs. This enables targeted interface selection when broadcasting an SSID across the wireless infrastructure.

Common mistakes.

A. Mobility groups define trust relationships between WLCs for inter-controller roaming and have no function related to controlling which APs broadcast an SSID or which interfaces are assigned to it.
B. FlexConnect groups are used to manage configuration and policies for FlexConnect-mode APs in branch deployments and do not provide interface-to-SSID assignment functionality.
D. AP groups allow per-group WLAN and interface overrides for sets of APs but are not the mechanism specifically designed to group and assign interfaces to WLANs as a primary function.

Concept tested. WLC interface groups for SSID interface assignment
