You have installed a new 802.11ac WLAN configured with 80 MHz channels. Users in one area are complaining about poor performance. This area is currently served by a single AP. You take a spectrum analysis capture in the poor performing area. While examining the waterfall plot you notice the airtime utilization is higher on the first 20 MHz of the 80 MHz channel when compared to the rest of the channel. What do you conclude?

A. The first 20 MHz is the AP's primary channel and higher airtime utilization on the primary channel is normal when an AP Is configured for 80 MHz operation

B. The AP is misconfigured and needs to be reconfigured to 80MHz operation

C. RRM is enabled and has dynamically picked a 20 MHz channel

D. Non Wi-Fi interference is preventing the APs 80 MHz operation

出題：4

Using the exhibit as a reference, answer the following.

STA1 sent a data frame to Mesh AP2 destined for a local file server on the same subnet with MAC address 00:11:22:33:44:55. Mesh AP2's mesh forwarding algorithm determined that the frame should be forwarded through Mesh AP1.
In the frame sent from Mesh AP2 to Mesh AP1, what is true of the contents of the MAC header?
(Choose 3)

A. From DS = 1

B. RA = Mesh AP1's MAC Address

C. To DS = 0

D. SA = Mesh AP2's MAC Address

E. TA = STA1's MAC Address

F. DA = 00:11:22:33:44:55

出題：7

You are considering disabling the data rates of 1, 2, 5.5 and 11 in the 2.4 GHz band.
What advantage might this provide to the networks operating in this band?

A. The RF signals will not travel as far

B. The antennas will be able to zero in on the higher data rates better

C. The range of the PHY preamble and header will be reduced

D. Frames that must be transmitted at the lowest common data rate can be transmitted at higher data rates after the change

Which statement is true regarding the Association Identifier (AID) used in IEEE 802.11 WLANs?

A. The AID has a maximum value of 2048, and is used to uniquely identify a wireless client station associated with an access point.

B. The AID field is present only in Beacons frames.

C. The AID has a maximum value of 2007, and resides in the duration/ID field of a PS-Poll frame.
