What is the first step in the CSMA/CA process when a wireless client is attempting to communicate on the wireless network?

• The client sends an RTS message to the AP.
• The client sends a test frame onto the channel.
• The client listens for traffic on the channel.
• The AP sends a CTS message to the client.

Explanation: When a wireless client is attempting to communicate on the network, it will first listen to the channel to be sure it is idle. Next, the client sends an RTS message to the AP to request dedicated access to the network. The AP will then send a CTS message granting access to the client. The client will then transmit data.
