Options :

A :

Place APs in the center of the required area and make sure that every client device is able to hear at least three APs

B :

Place APs on the perimeter and throughout the required area and make sure that every client device is able to "hear" at least three APs

C :

Place APs in the center of the required area and make sure that every client device is able to hear at least two APs

D :

Place APs on the perimeter of the required area and make sure that every client device is able to "hear" at least one AP

Answer: B

Question 2

After deploying a 5 GHz-only WLAN infrastructure in the USA, using 20 MHz channel widths and all 25 available channels, a manager tests the Guest SSID on his 802.11n tablet. During testing, he experiences several areas with poor RSSI (below -80 dBm) or no signal at all. Upon checking, all APs are operational, and coverage was validated post-deployment. What is the likely cause of this issue?

Options :

A : His tablet doesn't support the 5 GHz band

B : His tablet only supports a 40 MHz channel-width

C : His tablet does not support one or more of the 5 GHz channels

D : His tablet doesn't support MU-MIMO

Answer: C

Question 3

To ensure that your design meets the requirements of the WLAN, what should be defined in your WLAN design software that will result in different requirements at varying locations on the floor plan?

Options :

A : Requirement areas

B : Cable runs

C : Heatmap colors

D : Project name

Answer: A

Question 4

What statements are true regarding jitter and latency?(Choose all that apply.) Response:

Options :

A : Jitter is a measurement of latency variability from one frame to another.

B :

Jitter is a measurement of the variance of the number of frames received from an application for a specific time interval.

C : Jitter is a measurement of average latency based on a sample of >100 frames.

D : Latency is a measurement of the time delay experienced in the delivery of a frame.

E : Latency is a measurement of the time required to transmit two subsequent frames.

Answer: A,D

Question 5
