  A. Bluetooth
  B. Wi-Max
  C. DECT phone
  D. microwave
  E. analog camera
  D. microwave

• Question 143:

  Customer requirements and a WLAN site survey require a Cisco 1250 AP operating at full 802.11a/b/g/n located approximately 150 meters from the closest IDF. What is the best solution to provide wireless coverage to this portion of the customer's facility?

  A. At the AP location, install a power drop and a Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-1000AF) to power and the Cisco 1250 and extend the Cat 5 link.
  B. Install an external Cisco Mid-Span 802.3af power injection panel in the same rack as the access switch to extend the driven distance of the structured cable plant.
  C. At the AP location, install a power drop and a Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-FIB) for the Cisco 1250. Then connect a Cat 5 cable from the AP to a fiber-optic-to-copper transceiver which connects to a fiber link to the IDF. At the access switch, connect the fiber cable from the AP location to a fiber-optic port on the switch.
  D. At the AP location, install a power drop and a Cisco AIR-PWRINJ4 power adapter for the Cisco 1250. Connect the Cat 5 cable to the AP from the IDF.
  E. At the AP location, install a local power drop and local power supply for the Cisco 1250. Connect the AP through a pair of fiber-optic-to-copper transceivers back to the access layer switch to provide data access.
  E. At the AP location, install a local power drop and local power supply for the Cisco 1250. Connect the AP through a pair of fiber-optic-to-copper transceivers back to the access layer switch to provide data access.

• Question 144:

  An engineer would like to calibrate the RF environment to improve accuracy. What wireless attribute is added to the floor-level calculation by calibrating the floor?

  A. TX power
  B. multipath
  C. SNR
  D. attenuation
  D. attenuation

• Question 145:

  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.
  A. Unsupported channels can cause coverage holes for clients as well as limit their connectivity.

• Question 146:

  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 802.11b activity
  B. Normal 802.11g activity
  C. Microwave oven interference
  D. Video camera interference
  E. Bluetooth device interference
  A. Normal 802.11b activity

• Question 147:

  What two tools can an engineer use to verify RF data rates and coverage after installation? (Choose two.)

  A. Cisco WCS Planning Mode
  B. Cisco WCS Location Readiness Tool
  C. Cisco WCS Voice Audit Report
  D. AirMagnet Passive Survey Mode
  E. AirMagnet Active Survey Mode
  F. AirMagnet Planner Mode
  D. AirMagnet Passive Survey Mode
  E. AirMagnet Active Survey Mode

• Question 148:

  In post-deployment testing you have identified an area where there is a substantial rate- shift issue causing problems with the existing Cisco 7921 phones. How might you resolve this issue?

  A. Increase the AP power level to maintain higher throughput further away from the AP.
  B. Increase client RSSI, SNR, and retry values to maintain connectivity to the original AP for as long as possible.
  C. Change VoWLAN to 7925 phones.
  D. Reduce the power level of the AP so that roaming occurs before the client experiences the substantial rate shift.
  D. Reduce the power level of the AP so that roaming occurs before the client experiences the substantial rate shift.

• Question 149:

  C. 100 feet
  D. 150 feet
  E. 225 feet
  B. 80 feet
