A customer is implementing a massively scaled guest wireless network to support approximately 32,000 clients. For ease of administration, they have required implementing multiple interfaces defined on the WLC and mapped to a single interface group. Which configuration meets this need?

Question

Accepted Answer

D. 33 interfaces of /22 sized networks A /22 subnet provides 1,022 usable host addresses, so 33 interfaces yields approximately 33,726 total addresses, sufficient for 32,000 clients. Cisco WLC interface groups support a maximum of 64 interfaces per group, and 33 falls well within that limit. The other options require 66, 132, or 264 interfaces, all of which exceed the 64-interface-per-group ceiling.

Answer

A. 264 interfaces of/25 sized networks 264 interfaces of /25 far exceeds the Cisco WLC interface group maximum of 64 interfaces, making this configuration architecturally unsupported regardless of address space.

Answer

B. 132 interfaces of/24 sized networks 132 interfaces of /24 exceeds the maximum number of interfaces allowed in a single WLC interface group, rendering this option invalid.

Answer

C. 66 interfaces of/23 sized networks 66 interfaces of /23 exceeds the 64-interface-per-group platform limit by two, making it non-compliant with the WLC's interface group constraint.
