What is an attribute of the workgroup bridge mode for an AP in a wireless network?

In workgroup-bridge (WGB) mode an AP associates to a root AP and bridges traffic from the Ethernet segment that is cabled to its own port, permitting wired devices that have no 802.11 capability to join the WLAN as if they were Wi-Fi clients.

A. Radios remain independent; WGB mode does not create inter-band client communication.

B. VLANs are not automatically extended across all interfaces; bridging occurs only between the WGB’s Ethernet and its wireless link.

C. A WGB has only one Ethernet interface, so there is no intra-Ethernet port switching.
