CWDP: Certified Wireless Design Professional v303 — Question 28

A controller-based WLAN infrastructure has its controller on a different subnet than its APs. What device must be used to enable any communication between the
Controller and the APs?

Answer options

• A. NTP server
• B. Router
• C. PoE Layer 2 switch
• D. Wireless bridge

Correct answer: B

Explanation

A router is essential for routing traffic between different subnets, allowing the Controller and the APs to communicate effectively. The other options, such as an NTP server and a PoE Layer 2 switch, do not provide the necessary routing capabilities, while a wireless bridge is not relevant in this context.
