Question 8

When a client station sends a broadcast probe request frame with a wildcard SSID, how do APs respond?

For each probe request frame, only one AP may reply with a probe response.

Each AP responds in turn after preparing a probe response and winning contention.

Each AP checks with the DHCP server to see if it can respond and then acts accordingly.

After waiting a SIFS, all APs reply at the same time with a probe response.

Correct Answer: B

When a client station sends a broadcast probe request frame with a wildcard SSID, each AP that receives the request will respond independently. The APs will prepare their probe responses and then attempt to transmit them after competing for access to the medium using the standard contention process. This ensures that the APs do not transmit their responses simultaneously, which would result in collisions.
