Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 212

Which two actions, when applied in the LAN network segment, will facilitate Layer 3 CAPWAP discovery for lightweight AP? (Choose two.)

Answer options

• A. Utilize DHCP option 43.
• B. Utilize DHCP option 17.
• C. Configure an ip helper-address on the router interface.
• D. Enable port security on the switch port.
• E. Configure WLC IP address on LAN switch

Correct answer: A, C

Explanation

Using DHCP option 43 helps lightweight APs discover the WLC by providing its IP address through DHCP. Configuring an ip helper-address allows the router to forward DHCP requests to the appropriate server, which is crucial for the discovery process. The other options, such as enabling port security or using DHCP option 17, do not directly assist in Layer 3 CAPWAP discovery.
