What standard is referenced in the 802.11-2016 specification and is recommended for robust WLAN client security?
- A . SSID hiding
- B . WEP
- C . 802.1X/EAP
- D . IPSec VPN
When is an 802.11ac AP transmitting on 5 GHz required by the IEEE 802.11-2020 standard to respond to probe request frames from nearby client stations? (Choose all that apply.)
- A . When the probe request frames contain a null SSID value
- B . When the probe request client is also an 802.11ac radio
- C . When the probe request is encrypted
- D . When the probe request has the Power Management bit set to 1
- E . When the probe request frames contain the correct SSID value
In an enterprise WLAN, what condition will prevent a dual-band VHT/HT client device from performing a fast and seamless transition (i.e. latency-sensitive applications are not disrupted) between two access points that are managed by the same WLAN controller?
- A . The current AP is using channel 1 and the new AP is using channel 40.
- B . The SSID of the current AP does not match the SSID of the new AP.
- C . The current AP supports only HT and the new AP is VHT capable.
- D . The access points are hiding the SSID in Beacons and Probe Response frames.
