one that has a receiver sensitivity of -70 dBm
one that has the lowest receiver sensitivity
one that has the most updated wireless card
one that has 802.11a wireless support
An engineer must produce a passive survey report. The coverage heat map shows the entire site with all signal levels. To see only the desired coverage, which action must the engineer take?
Change the color scheme to show the desired heat map.
Use the RSSI calibration tool to configure the receiver sensitivity.
Use the RSSI slider to set the heat map to the desired cutoff lter.
Filter the results to show the desired APs only.
An engineer is performing an AP-on-a-stick survey and nds 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.)
Raise the minimum data rate to 24 Mbps.
Increase AP transmit power to improve the SNR.
Allow the use of UNII-2e channels.
Use directional antennas to limit the coverage area of some APs.

MAP hostnames
Rx power
mesh on 2.4 GHz band
bridge group name
Tx power
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?
location services, VoIP, data, and video
streaming video with VoIP, data, and HD resolution
location-based services, BYOD preparation, and HD video streaming
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?
location
data
video
voice
A wireless engineer must assess constraints for a future WLAN deployment for a site that consists of oce cubicles. Which signal propagation attenuation result is associated with this environment?
re ection
absorption
noise
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?
Enable BSS transition at the radio level and optimized roaming on the SSID.
Disable coverage hole detection on the SSID and enable BSS transition on the SSID.
Disable optimized roaming and enable 802.11v support on the SSID.
Enable BSS transition on the SSID and optimized roaming at the radio level.
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 of harsh weather. Which two parameters must the engineer consider to prevent an outdoor wireless outage? (Choose two.)
lightning arrestor installation
antenna cable grounding
cable strength
cable length
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 trac 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?
Enable CCKM on the voice SSID and add APs to a FlexConnect group.
Enable Aironet IE on the voice SSID and add APs to an AP group.
Enable Aironet IE on the voice SSID and add APs to a FlexConnect group.
Enable CCKM on the voice SSID and add APs to an AP group.
