1. Which of the following statements is correct (Select 3 Answers)?

WDS can transmit the data of the wired network through the wireless network as a relay architecture, thereby transmitting the network data to another wireless network environment or another wired network.

The wireless network bridging function usually refers to one-to-one, but the WDS architecture can do one-to-many.

WDS allows wireless APs to bridge (relay) wirelessly, but bridged wireless APs cannot provide coverage at the same time.

Because virtual network lines are formed through wireless networks, WDS is also called wireless network bridging.
