Which of the following statements are correct? (Multiple choice)

Question

Options

• AWDS can transmit the data of the wired network through the relay structure of the wireless
• BThe wireless network bridging function usually refers to one-to-one, but the WDS architecture can
• CWDS can allow wireless APs to bridge (relay) wirelessly, but the bridged wireless APs cannot
• DBecause a virtual network line is formed through a wireless network, WDS is also called a wireless

• A
  84% (31)
• C
  16% (6)

Explanation

WDS (Wireless Distribution System) is a protocol that lets wireless access points (APs) communicate with each other wirelessly to extend or bridge networks.

Why A, B, and D are correct:

• A is correct because WDS uses a wireless relay structure to carry wired network data - APs bridge the wired LAN segments over the air, effectively extending the wired network without physical cables.
• B is correct because standard wireless bridging is point-to-point (one AP to one AP), whereas WDS supports more flexible topologies - one AP can relay to multiple APs simultaneously, enabling mesh-like or star structures.
• D is correct because WDS creates a virtual wireless "wire" between APs, which is why it's commonly called a wireless backbone or wireless virtual link - the wireless channel acts as a substitute for a physical cable run.

Why C is wrong:

C implies that WDS-bridged APs cannot serve wireless clients - but this is false. A key advantage of WDS over simple bridging is that relaying APs can simultaneously bridge to other APs and serve client devices, making it far more versatile.

Memory tip: Think of WDS as a "wireless extension cord" - it stretches your wired network through the air (A, D), and unlike a basic one-to-one bridge, it branches out to multiple APs while still letting clients plug in (B, not C).
