  You are performing a post-implementation validation survey. What basic tool can be used to easily locate areas of high co-channel interference?

  A. Throughput tester

  B. Laptop-based spectrum analyzer

  C. Access point spectrum analyzer

  D. Wi-Fi scanner

  Correct Answer: D

• Question 154:

  A non-802.11 device is suspected of causing interference on the WLAN. You are not certain of the location or type of device. What is the best solution for locating this non-802.11 device?

  A. Access point spectrum analyzer

  B. Laptop-based spectrum analyzer with an omni-directional antenna

  C. Laptop-based spectrum analyzer with an omni-directional antenna

  D. Laptop-based spectrum analyzer with a directional antenna

  Correct Answer: D

• Question 155:

  During a post-implementation survey, you have detected a non-802.11 wireless device transmitting in the area used by handheld 802.11g scanners. What is the most important factor in determining the impact of this non-802.11 device?

  A. Receive sensitivity

  B. Channel occupied

  C. Airtime utilization

  D. Protocols utilized

  Correct Answer: C

• Question 156:

  You are tasked with performing a throughput test on the WLAN. The manager asks that you use open source tools to reduce costs. What open source tool is designed to perform a throughput test?

  A. iPerf

  B. PuTTy

  C. IxChariot

  D. Python

  Correct Answer: A

• Question 157:

  You have received a report of poor wireless connections on the third floor of a building under your administration. Three individuals have reported the problem. Apparently, the connections are reporting a strong signal, but the users cannot access the Internet. With the problem identified, what is the next logical step in the troubleshooting process?

  A. Verify the solution

  B. Discover the scale of the problem

  C. Perform corrective actions

  D. Create a plan of action or escalate the problem

  Correct Answer: B

• Question 158:

  Your manager asked you to locate a solution that allows for centralized monitoring of WLAN performance over time. He wants a single pane of glass for administration and monitoring of the solution. What do you recommend?

  A. Laptop-based spectrum analyzers

  B. AP-based spectrum analysis

  C. Overlay WLAN monitoring solution

  D. Laptop-based protocol analyzers

  Correct Answer: C

  AP Spectrum analysis does not qualify as a centralized solution for WLAN performance. An overlay monitoring system should be the right answer.

• Question 159:

  You were previously onsite at XYZ's facility to conduct a pre-deployment RF site survey. The WLAN has been deployed according to your recommendations and you are onsite again to perform a post- deployment validation survey.

  When performing this type of post-deployment RF site survey voice over Wi-Fi, what is an action that must be performed?

  A. Spectrum analysis to locate and identify RF interference sources.

  B. Frequency-band hopping analysis to detect improper RF channel implementations.

  C. Application analysis with an active phone call on an VoWiFi handset.

  D. Protocol analysis to discover channel use on neighboring APs.

  Correct Answer: C

• Question 160:

  A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11ac AP. Both the client and AP are 2x2:2 devices. What is the likely cause of the low data rate issue?

  A. Weak signal strength

  B. CAT5e cabling run to the AP

  C. Too few spatial streams

  D. Lack of support for 802.11n

  Correct Answer: A
