Roy has been hired to troubleshoot an enterprise Wi-Fi 6 network. The customer has recently deployed dual-frequency 4×4:4 APs that also include a third-sensor radio for WIPS monitoring. Most of the APs are operating with full functionality; however, the APs in one building seem to only be operating as 2×2:2 radios and the sensor radio has stopped working.
What is the most likely root cause of this problem?
- A . The problem APs are connected to switch ports that are only capable of 1 Gb uplinks.
- B . The problem APs are connected to switch ports that are only 802.3af (15.4 watts) capable.
- C . The problem APs are connected to access switch ports and not 802.1Q trunk ports.
- D . The problem APs are connected to 802.1Q trunk switch ports and access trunk ports.
- E . The problem APs are connected to half-duplex switch ports.
Which of these security methods is the replacement for PSK authentication as defined by WPA3?
- A . Per-user/per-device PSK
- B . Wi-Fi Protected Setup (WPS)
- C . Simultaneous authentication of equals (SAE)
- D . EAP-SIM
- E . WPA2-Personal
