CWDP: Certified Wireless Design Professional v303 — Question 13

Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined?

Answer options

• A. All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
• B. All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
• C. All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
• D. The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.

Correct answer: D

Explanation

The correct answer is D because the client relies on its stored mappings of MAC addresses to BSSIDs to select the appropriate AP. Options A, B, and C incorrectly describe how the AP selection process works, as they refer to shared IP addresses, multicast addresses, and BSSIDs, which do not dictate how the client identifies its associated AP.
