Demo Questions

Question 1
Your customer is using PSK as their only authentication. They have an industry requirement to move to a stronger solution. Your recommendation is to move to a certificate-based type of authentication where both the client and server require certificates. Which EAP type would be the best fit?
  1. EAP-FAST
  2. EAP-TTLS
  3. EAP-TLS
  4. PEAP

Question 2
A company wants to connect its headquarters to its remote office that is 13 kilometers away using a wireless bridge. 
What requirement must not be forgotten by their Wireless Engineer when considering the Fresnel Zone?
  1. Earth bulge
  2. Antenna gain

Question 3
A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel’s SSID and notices an AP in the hotel room. However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby. 
What would be the most likely cause of the low RSSI in the hotel room?
  1. The AP in the room is using ZigBee instead of Wi-Fi.
  2. The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.
  3. The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.
  4. The AP in the room is using Bluetooth instead of Wi-Fi.
Correct answer: C
Question 4
A museum wants to offer Wi-Fi to its visitors. One of their requirements is to have the APs blend into the design of the museum. What should you do to meet this requirement?
  1. Lock the AP inside of a metal box
  2. Place the APs in between walls and I-beams
  3. Use an 802.11b AP, so it looks old enough to be in a museum
  4. Use a plastic cover that could blend in with the environment

Question 5
A customer is acquiring a new VoWLAN system to replace their existing wired phone system. When reading about his system’s requirements, you learned that is requires 25 db of SNR to work as expected. After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system’s requirements?
  1. -70 dBm
  2. -67 dBm
  3. -65 dBm
  4. -63 dBm
Correct answer: B
Question 6
When designing a static channel plan for an office using voice devices near an airport, which range of channels should be avoided to ensure optimal performance when implemented?
  1. 36-40
  2. 44-48
  3. 116-124
  4. 1-11
Correct answer: C
Question 7
What is the most suitable antenna option to be used when designing a WLAN infrastructure with APs mounted on a ceiling with a height of more than 20 feet and having all of the client stations used from the floor?
  1. Patch
  2. Dish
  3. Grid
  4. Low-gain dipole
Correct answer: C
Question 8
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?
  1. 11 dBm
  2. 6.25 mW
  3. 125 mW
  4. 17 dBm
Correct answer: D
Question 9
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?
  1. It does not give you enough bandwidth to collect data coming from all of the adapters.
  2. It does not give you enough power for all four of your adapters.
  3. It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.
  4. It generates noise in the 5 GHz band, giving you a false perception of the noise floor.
Correct answer: C

Question 10
Your customer requires fast secure roaming. Which two types of roaming are specified in 802.11-2016 FT roaming that will help meet this goal?
  1. Over-the-Air and Over-the-DS
  2. Over-the-Air and Over-the-Wire
  3. FT and OKC
  4. FT and TKIP
