Demo Questions

Question 1
You are attempting to work through a user complaint with the CWNP-recommended troubleshooting methodology.
What must be clearly identified in order to reduce the number of possible causes at step three?
  1. The user name
  2. The problem
  3. The device type
  4. The user’s IP configuration
Correct answer: B
Question 2
Several users have reported WLAN network connection issues and the users connect to the same AP. These users are spread throughout a 320 square meter area. Using a spectrum analyzer, you see RF energy across the entire 2.4 GHz band at significant signal strength levels. The users all connect using either HT or ERP devices.
What is the likely cause of this problem within this area?
  1. Wide-band jammer
  2. Microwave oven
  3. Bluetooth devices
  4. Video camera
Correct answer: A
Question 3
You need to determine RF activity over time in a spectrum analyzer. It is to be able to see the activity and the amplitude of that activity.
What kind of view should be used?
  1. Real-time FFT
  2. Device listing
  3. Channel listing
  4. Swept spectrogram
Correct answer: D
Explanation:
The FFT shows spectral activity in the frequency domain, while waterfall or swept spectrogram views attempt to represent RF activity over time

Question 4
You suspect an interfere may exist in a BSS that is experiencing sporadic problems. You want to identify and locate the device. The actual device identify is not known.
What tool should be used for this purpose?
  1. Spectrum analyzer
  2. Cable tester
  3. Throughput tester
  4. Protocol analyzer
Correct answer: A
Question 5
While troubleshooting DHCP issues, you perform a protocol capture in order to determine if the DNCP pool is depleted. The capture does not show DHCPnak messages.
Where else could you look to determine if the pool is depleted?
  1. Switch logs
  2. DHCP server logs
  3. Spectrum analyzer
  4. AP logs
Correct answer: B
Explanation:
A very common problem for WLANs is DHCP pool depletion. This occurs because many wireless clients come-and-go from the network quickly. If a client connects for only two or three minutes and the lease duration is set to multiple days (3-8 days is not uncommon), the IP address will be lost for that entire time. To resolve such issues, create more pools and reduce the lease duration to hours instead of days. Look for DHCP negative acknowledgement or server log errors to determine if the IP pool is depleted.

Question 6
You are considering disabling the data rates of 1, 2, 5.5 and 11 in the 2.4 GHz band.
What advantage might this provide to the networks operating in this band?
  1. The antennas will be able to zero in on the higher data rates better
  2. The range of the PHY preamble and header will be reduced
  3. Frames that must be transmitted at the lowest common data rate can be transmitted at higher data rates after the change
  4. The RF signals will not travel as far
Correct answer: C
Question 7
What is the formula used to calculate the Duration field value in an RTS frame?
  1. RTS Duration field = CTS duration
  2. RTS Duration field = Data or management to be sent frame duration
  3. RTS Duration field = Data or management frame to be sent duration + CTS duration + one ACK duration + three SIFS
  4. RTS Duration field = Data or management frame to be sent duration + CTS duration
Correct answer: C
Question 8
You view a protocol analyzer capture decode with the following protocol frames listed in the following order (excluding the ACK frames): 1) 802.11 Probe Request and 802.11 Probe Response 2) 802.11 Auth and another 802.11 Auth 2) 802.11 Assoc Req and 802.11 Assoc Rsp 4) EAPOL-Start 5) EAP Request and EAP
Response 6) EAP Request and EAP Response 7) EAP Request and EAP Response 8) EAP Request and EAP Response 9) EAP Request and EAP Response
10) EAP Success 19) EAPOL-Key (4 frames in a row)
What are you seeing in the capture file?
  1. WPA2-Personal authentication
  2. Wi-Fi Protected Setup with PIN
  3. WPA2-Enterprise authentication
  4. 802.1X with Dynamic WEP
Correct answer: C
Question 9
ABC Company requires the ability to identify and quickly locate rogue devices. ABC has chosen an overlay WIPS solution with Wi-Fi sensors that use dipole antennas to perform this task. No other sensors are included. Use your knowledge of location tracking techniques to answer the question.
Which one of the following location methods is not available in the described system?
  1. GPS Positioning
  2. Time Difference of Arrival (TDoA)
  3. RF Fingerprinting
  4. Trilateration of RSSI measurements
Correct answer: C
Question 10
You have implemented centralized, infrastructure-based spectrum analysis. The Aps are configured to perform spectrum analysis in an ad-hoc manner and will go offline as Aps to perform this duty when needed.
What unique method of spectrum analysis monitoring is provided by this solution that is not typically available in a laptop-based analyzer?
  1. Web-based viewing
  2. Real-time FFT
  3. Band selection
  4. RBW adjustments
Correct answer: D
