Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 92

An indoor 1240 AP is booting and has obtained an IP address using DHCP. The AP has confirmed prior controller IP addresses from a previously joined mobility group stored in NVRAM. What is the next step the AP performs?

Answer options

• A. DHCP option 43.
• B. DNS resolution of CISCO-LWAPP-CONTROLLER.localdomain.
• C. Layer 2 LWAPP discovery broadcast.
• D. Layer 3 LWAPP discovery broadcast.
• E. Ping each Cisco WLC to verify its current status.
• F. Select a Cisco WLC based on its position in the configured join selection sequence.

Correct answer: A

Explanation

The AP first utilizes DHCP option 43 to retrieve the IP address of the controller it should join, as this option provides information about controller addresses. The other options, such as DNS resolution and LWAPP discovery broadcasts, are either performed later or are not the immediate next step after obtaining an IP address.
