During a Wi-Fi client's association with an access point, which sequence of frames is exchanged after the client receives a beacon or probe response?

Authentication request/response, then Association request/response

Probe request/response, then Authentication request/response

Reassociation request/response, then Authentication request/response

Association request/response, then Authentication request/response

Which condition is most likely to cause a client to initiate a roam to a different access point?

The current AP's channel utilization is high, causing throughput degradation

The AP's SSID is broadcast in a beacon

The client's IP address lease is about to expire

A hospital uses Wi-Fi for VoIP phones. The phones support 802.11r, 802.11k, and 802.11v. The network team wants to ensure that calls are not dropped during roaming. Which feature should be enabled to allow the phones to proactively discover neighboring APs?

802.11v BSS transition management

802.11w protected management frames

What distinguishes Layer 2 (L2) roaming from Layer 3 (L3) roaming in a Wi-Fi network?

L2 roaming is only possible with WPA2-Enterprise, while L3 roaming works with WPA2-Personal

L2 roaming uses 802.11r fast roaming, while L3 roaming uses 802.11k

L2 roaming requires a controller, while L3 roaming can be done without one

L2 roaming occurs between APs on the same subnet, while L3 roaming occurs between APs on different subnets
