Options :

A : VoIP

B : E-Mail

C : RTLS

D : FTP

Answer: A

Question 2

What statement about the IEEE 802.11-2016 QoS facility is true?

Options :

A : 802.11 control frames are assigned to the 802.11 EF priority queue

B : When the Voice queue has frames awaiting transmission, no data will be transmitted from the Best Effort queue.

C : Four 802.1p user priorities are mapped to eight 802.11 transmit queues.

D : 802.11 QoS is achieved by giving high priority queues a statistical advantage at winning contention.

Answer: D

Question 3

In a long-distance RF link, which statement about Fade Margin is true?

Options :

A : The Fade Margin of a long-distance radio link should be equivalent to the receiver’s low noise filter gain.

B : A Fade Margin is unnecessary on a long-distance RF link if more than 80%

C : Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading

D : The Fade Margin is a measurement of signal loss through free space and is a function of frequency and distance

Answer: C

Question 4

You are installing an AP to be used by 23 laptops. All laptops will connect on the 5 GHz frequency band. A neighbor network uses channels 1 and 6. What channel should be used for this AP and why?

Options :

A : A 5 GHz channel, because channels 1 and 6 are 2.4 GHz channels they have no impact on the decision

B : Channel 1, because it is best to use the channel with the lowest frequency

C : Channel 11, because channels 1 and 6 are in use nearby

D : Channel 6, because it is always best to use this channel

Answer: A
