Q11. Refer to the exhibit.
After performing a Layer 1 survey using Cisco Spectrum Expert, what is the result indicated by the visual screen?
A. Normal 802.11g activity
B. Microwave oven interference
C. Video camera interference
D. Bluetooth device interference
E. RF jammer
Answer: B
Q12. When using WCS 7.0 to calibrate a floor, is it more important to collect 50 or more distinct locations or to collect 150+ measurements?
A. 150+ measurements are more important than the locations because the information gathered is more granular.
B. Collecting 50 or more distinct locations is more important because this provides a wider coverage across the floor being calibrated.
C. Depending on the size of the floor 50+ distinct locations and 150+ measurements may provide divergent information that requires more data collection.
D. When calibrating a floor 50 or more distinct locations will yield 150+ measurements because multiple measurements are collected at each distinct location.
Answer: D
Q13. A company has requested an indoor wireless survey in a multi-tenant building for 2.4GHz data and 5GHz voice services. Data clients will require three spatial streams and 4x4 MIMO technology. What is the Cisco recommended Access Point for performing this survey?
A. 600
B. 1600
C. 2600
D. 3600
Answer: D
Q14. How would clients react to a controller configuration that utilized unsupported channels?
A. Unsupported channels can cause coverage holes for clients as well as limit their connectivity.
B. Unsupported channels would be ignored by clients.
C. Unsupported channels would have no impact on clients. The user would simply need to roam to a supported channel.
D. Unsupported channels are not configurable on the controller, thus there would be no impact on clients.
Answer: A
Q15. What are two reasons that it is always preferable to obtain a digital copy of the "as built" drawings for a site you need to perform a WLAN site survey on? (Choose two.)
A. A digital copy of the "as built" drawings is always more accurate than design drawings because it includes the placement of office furniture.
B. A digital copy of the "as built" drawings includes all the changes made during construction that are not included in the design drawings.
C. A digital copy of the "as built" drawings includes a full set of preliminary mechanical drawings so sources of interference, diffusion, and absorption can be easily identified.
D. A digital copy of the "as built" drawings allows you to more accurately estimate physical AP placement in the customer environment.
E. A digital copy of the "as built" drawings assists in the placement of WLAN equipment so the WLAN signal minimizes wired network delay.
Answer: B,D

D. ISM Band
Answer: B
Q17. Which choice best describes RF challenges for outdoor mesh site survey and deployment?
A. Reflection
B. Reflection, absorption
C. Diffraction
D. Diffraction, scattering
E. Reflection, absorption, diffraction, scattering
Answer: E
Q18. What measurement can Iperf be used to verify?
A. throughput
B. RSSI
C. SNR
D. interference detection
E. utilization
Answer: A
Q19. What is the vertical height that a MAP should not exceed for proper deployment?
A. 15 ft
B. 30 ft
C. 45 ft
D. 55 ft
Answer: B
Q20. When performing a post-installation audit with a auditing tool such as Ekahau, which two steps are associated with the active portion of the audit? (Choose two.)
A. Check that all channels are supported by the APs regardless of client capabilities.
B. Check for co-channel interference by standing near an access point on one channel and watching for other access points that are on the same channel.
C. Verify that the network traffic of physical data rate and packet loss meets user requirements.
D. Verify smooth roaming.
E. Check to see if the signal level on other access points that are heard on the same channel is at least 19 dBm weaker than the access point that you are next to.
Answer: C,D
