Which three statements concerning wireless network security are accurate? (Choose three.)

• A wireless client first associates with an AP and then authenticates for network access.
• WPA2-Personal prevents attackers from being able to use a key to unencrypt data that was already transmitted over the air.
• Every device using the WLAN must be configured with an identical pre-shared key, unless PSK with ISE is used.
• WPA versions use a three-way handshake procedure to exchange a pre-shared key between a client and an AP.
• Open authentication uses no client or AP verification.
• WPA1, WPA2, and WPA3 support both PSK or 802.1x client authentication modes.

Explanation: A wireless client first authenticates with an AP and then associates for network access. WPA versions use a four-way handshake procedure to exchange a pre-shared key between a client and an AP. WPA3-Personal prevents attackers from being able to use a key to unencrypt data that was already transmitted over the air.
