An engineer must install an outdoor wireless network for an area with a direct line of sight. The outdoor APs are in an open area with a history of harsh weather. Which two parameters must the engineer consider to prevent an outdoor wireless outage? (Choose two.)
A. lightning arrestor installation
B. antenna cable grounding
C. cable strength

E. elimination of trees
A customer has a central Cisco WLC that manages APs in FlexConnect mode. The wireless infrastructure supports multiple small branches. One branch deploys new CCX wireless phones that are authenticated by a central Cisco ISE via PEAP/IMSCHAPv2, and traffic is switched locally. The customer must reduce the number of full authentication requests and optimize roaming for the new phones. Which action accomplishes the requirement?
A. Enable CCKM on the voice SSID and add APs to a FlexConnect group.
B. Enable Aironet IE on the voice SSID and add APs to an AP group.
C. Enable Aironet IE on the voice SSID and add APs to a FlexConnect group.
D. Enable CCKM on the voice SSID and add APs to an AP group.
The wireless survey report shows APs staggered throughout a facility, with several of them placed on the exterior walls. Other APs are located at building corners and major turns in the structure layout. Assuming that all survey locations are optimized with a minimum of -67 RSSI at cell edges with 20% overlapping cells, for which purpose is this survey model used?
A. location services, VoIP, data, and video
B. streaming video with VoIP, data, and HD resolution
C. location-based services, BYOD preparation, and HD video streaming
D. voice, data clients, and video on demand
An engineer must perform a predictive design for a wireless network. The customer has devices that can tolerate at most 100 ms of delay when roaming. Which design criteria must be used?
A. location
B. data
C. video
D. voice
A wireless engineer must assess constraints for a future WLAN deployment for a site that consists of office cubicles. Which signal propagation attenuation result is associated with this environment?
A. reflection
B. absorption
C. noise
D. refraction
An engineer configured the optimized client roaming on Cisco WLC with an RSSI threshold of -72dBm. Clients report frequent disconnections. What must be configured for the AP to guide the client to a better AP?
A. Enable BSS transition at the radio level and optimized roaming on the SSID.
B. Disable coverage hole detection on the SSID and enable BSS transition on the SSID.
C. Disable optimized roaming and enable 802.11v support on the SSID.
D. Enable BSS transition on the SSID and optimized roaming at the radio level.
An engineer is performing an AP-on-a-stick survey and finds that the 5 GHz channel overlap is too high when an appropriate number of APs are used for the density requirements. Which two actions during the survey reduce channel overlap? (Choose two.)
A. Raise the minimum data rate to 24 Mbps.
B. Increase AP transmit power to improve the SNR.
C. Allow the use of UNII-2e channels.
D. Use directional antennas to limit the coverage area of some APs.
E. Enable power saving mode.
An engineer is designing a point-to-multipoint mesh network. Which two AP configurations must be completed for a site survey? (Choose two.)
A. MAP hostnames
B. Rx power
C. mesh on 2.4 GHz band
D. bridge group name
E. Tx power
An engineer is designing a wireless network to support hyperlocation in an environment that already has APs installed. During the survey, the engineer notices that the APs are pointing in different directions. What is the recommended way to align the APs to easily determine AP Azimuth, X-Y, and ceiling height information, and minimize confusion and user-entered errors?
A. APs must be aligned pointing toward the nearest wall.
B. APs must be aligned pointing toward each other.
C. APs must be aligned in the same direction.
D. APs can be aligned all four ways.
An engineer is performing an active survey of a network that must support different types of mobile devices. The devices must be able to run an application that requires a minimum RF of -73 dBm. Which mobile device must be used for the survey?
A. one that has a receiver sensitivity of -70 dBm
B. one that has the lowest receiver sensitivity
C. one that has the most updated wireless card
D. one that has 802.11a wireless support
