Question 27

When compared with legacy Power Save mode, how does VHT TXOP power save improve battery life for devices on a WLAN?

A. VHT TXOP power save allows stations to enter sleep mode and legacy Power Save does not.

B. VHT TXOP power save allows the WLAN transceiver to disable more components when in a low power state.

C. VHT TXOP power save uses the partial AID in the preamble to allow clients to identify frames targeted for them.

D. Legacy Power Save mode was removed in the 802.11ac amendment.

Correct Answer:C

Question 28

A. 100 meters

B. 300 meters

C. 328 meters

D. 200 meters

Correct Answer:A

Question 29

You manage a WLAN with 100 802.11ac access points. All access points are configured to use 80 MHz channels. In a particular BSS, only 40 MHz communications are seen. What is the likely cause of this behavior?

A. The short guard interval is also enabled.

B. The clients are all 802.11n STAs or lower

C. The AP is improperly configured to use only 40 MHz of the 80 MHz allocated bandwidth

D. All clients implement single spatial stream radios

Correct Answer:C
