• Question 33:

  After designing a WLAN infrastructure using predictive design software. What's the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?

  A. Deploy all of the APs as they're shown in the predictive design and perform an active site survey.

  B. Deploy all of the APs as they're shown in the predictive design and perform a passive site survey.

  C. Use a client device positioned where the APs will be installed and measure the signal from the client device.

  D. Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP's placement.

  Correct Answer: D

• Question 34:

  Why should band steering algorithms allow stations to connect to the 2.4 GHz band after some number of ignored Probe Requests?

  A. Because the FCC requires it.

  B. Because some clients are persistent clients that will not move on to the 5 GHz band.

  C. Because the 802.11 standard requires it.

  D. Because the AP will experience a buffer overflow if they do not eventually respond with a Probe Response.

  Correct Answer: B

• Question 35:

  When performing an active site survey in an existing WLAN infrastructure, in addition to gathering throughput data, what other important function will you typically be testing at the same time?

  A. Application filtering

  B. Internet bandwidth

  C. Roaming

  D. ACL configuration

  Correct Answer: C

• Question 36:

  You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized that the client devices used by your customer are getting lower RSSI values than that shown during your site survey. What is the most likely reason for this result?

  A. USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices.

  B. The transmit power on the APs is higher than needed.

  C. Regular Wi-Fi cards installed in client devices do not support the same protocols as survey adapters.

  D. USB Wi-Fi adapters have a greater sensitivity than internal Wi-Fi adapters.

  Correct Answer: A

• Question 37:

  What is the most cost-effective way to accurately measure the height of a ceiling when ladder use is not allowed?

  A. Estimate the height based on known object sizes

  B. Gather measurements from other objects and do the math

  C. Rent a lift-cart to lift you up to the ceiling

  D. Use a laser measure to measure the distance from the floor to the ceiling

  Correct Answer: D

• Question 38:

  Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4x4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface. Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support MultiGig, what is the best choice of cabling?

  A. Cat-5

  B. Cat-6

  C. Cat-5e

  D. Cat-6a

  Correct Answer: C

• Question 39:

  When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesn't have enough USB ports, you use a 4-port powered USB 3.0 hub. What issues could be caused by the use of USB 3.0 that will impact your site survey?

  A. It does not give you enough bandwidth to collect data coming from all of the adapters.

  B. It does not give you enough power for all four of your adapters.

  C. It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.

  D. It generates noise in the 5 GHz band, giving you a false perception of the noise floor.

  Correct Answer: C

• Question 40:

  When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW. What should be EIRP of the APs in the design?

  A. 11 dBm

  B. 6.25 mW

  C. 125 mW D. 17 dBm

  Correct Answer: D
