Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 119

A customer has a centralized wireless deployment with N+1 high availability and few open authentication SSIDs configured. After failover, all APs are broadcasting all SSIDs, but the clients are assigned IP addresses from a different subnet. The WLANs on both WLCs are configured with the same dynamic interfaces. Which feature must be incorporated in the wireless design of the second controller?

Answer options

• A. RF Profile
• B. AP Groups
• C. VLAN Select
• D. AAA Override

Correct answer: C

Explanation

The correct answer is C, VLAN Select, as it ensures that clients are assigned to the correct VLAN matching their SSID, allowing them to receive IP addresses from the intended subnet. Options A (RF Profile) and B (AP Groups) do not address the VLAN assignment issue, while D (AAA Override) pertains to authentication configurations rather than VLAN assignments.
