Question 1
During a post-validation survey, you find an area lacking any detectable Wi-Fi signal at all It is located behind an elevator shaft What is a common solution to this problem?
A. Move one or more APs so that indoor propagation results in coverage in that area or install another AP on that side of the elevator shaft
B. Turn up the power on the three APs closes! to that area
C. Install antennas with at least 3 more dB of gain on the two APs closest to that area

Question 2
You ate evaluating CO impact in 2 4 GHz. During the post-validation survey, you determine that 2 or 3 APs are seen from every location in the 2 4 GHz band with signal strengths above -75 dBm from all seen Aps. Does this show that CO has been removed from the environment given that three non- overlapping channels exist in 2.4 GHz and why?
A. Yes because you would see 3 APs m every location with a signal strength above -75 dBm if CO exists
B. Yes, because the goal is to see only l AP at each location in 2 4 GHz
C. No, because CCI can exist even with signals as low as -85 dBm to -93 dBm
D. No, because the goal is to see only 1 AP at each location in 2 4 GHz

Question 3
A designer has created a WLAN design that has been implemented in an organization. The network exists in a four-story building Because each floor has an Identical floor plan, the designer designed only one floor and had the installers duplicate the design on each floor. Now. in validation, it is not performing well What best explains the problem caused by this process?
A. The result was that APs were above and below each other on the same channel, resulting in excessive CCI The APs should have been deployed so that they were not directly above and below each other and so that they used varying channels between floors
B. The result was that clients could only connect to APs on their floor and, in a multi-floor deployment, you want clients to connect to APs on other floors in case they roam between floors.
C. The result was that AC) was increased because the APs were deployed above and below each other on the same channels.
D. The result was that the frequency utilization was too low for the clients to capture RF waves on which to transmit their signals.

Question 4
A WLAN that you designed has been deployed in one area, users ate complaining that the network performs poorly. When you analyze the area you see that a new interferer has been introduced that was not there during the pre-design survey You've been informed that the interferer cannot be removed as it is an essential loT device. What action do you recommend?
A. Reconfigure the channel plan to work around the interferer
B. increase the output power of the APs covering that area by at least 25 percent to overpower the interferer
C. Place a metal enclosure around the interferer
D. Use 40 MHz channels so that the devices can use either 20 MHz block depending on where the interferer operates

Question 7
What is the primary reason for avoiding 160 MHz channels with 802 11 in the 5 GHz band'?
A. Only two oi three 160 MHz channels exist in the current frequency allocation, tn some regulatory domains only one exists
B. The data rate becomes too high which causes some clients to gam access to the medium and never let it go
C. The output power requited for 160 MHz channels is more than most regulatory domains allow
D. No APs exist in production that can implement 160 MHz channels

Question 12
During a validation site survey, you realize that the installers mounted some of the APs on the wait when the design called Tor a celling mount. They said that this was done because the cabling company did not have the right tools to run the cables above the ceiling. You know that this will cause a difference in how the Wi-Fi signal will radiate throughout the environment. What should you do in this case?
A. Leave it as it is because it will not have a significant impact
B. Blame the cabling company it the Wi-Fi doesn't work since they didnot do their job correctly
C. Turn up the power on the APs to accommodate for the difference
D. Advise the stakeholder that requirements will not be met and a new design process will be needed to meet the requirements

Question 13
Install technicians are deploying a multi-floor WLAN that you have designed They have finished the first floor and all APs on that floor are powered on and functioning No APs on any other floors have been deployed at this time You are considering performing a post-deployment site survey of the first floor immediately to validate proper implementation What statement is true about this site survey if you perform it?
A. It will miss any impact on the WLAN caused by APs on other floors
B. It will show you how the first floor will function after all other floors are deployed
C. It will not work because the controllers cannot function properly until all APs licensed lo the controller are operational
D. It will result in a complete set of data informing you how clients will function after the entire WLAN is implemented

Question 15
You have designed a WLAN with a plan for 87 APs m a large office building. The customer has informed you that the budget is not as large as they hoped and they can only purchase 53 APs What action should be taken?
A. Simply increase the output power of the APs by 30 percent to accommodate tor the smaller number of purchased APs
B. Perform a complete redesign of the wireless network and inform the customer if some original requirements cannot be accomplished
C. Remove as many walls as possible within the facility so that the signals can travel a g<eater distance
