Wireless bridges always work in pairs.

• A. True
• B. False
• C. Usually yes
• D. Only with a specific standard

Answer: (A)

Wireless bridges connect two separate LANs over a wireless link, so the bridge can forward frames between the two networks as if they were one extended network. To make that happen, you place a bridging device at each end of the link; the two devices communicate with each other and pass traffic across the wireless connection. Without a second endpoint, there’s nowhere for the traffic on the far side to go, so a bridge can’t form the required link by itself. In practice, you configure two devices—often two APs or dedicated bridge units, sometimes using a feature like WDS—to establish the point-to-point connection. Because a bridge’s purpose is to join two networks, the setup inherently involves two endpoints, making the statement true.
