• Question 27:

  Given: As you prepare for a site survey in a hospital, you have learned about several wireless devices that support connection-oriented, real-time applications. These applications are sensitive to service interruptions and require excellent signal quality, low latency, and low loss. For that reason, it is important to identify sources of RF interference as well as building characteristics that would cause RF blockage or dead spots.

  What systems or environmental characteristics are most likely to cause interference or RF blockage and disrupt service for these applications? (Choose two)

  A. Microwave ovens
  B. Long hallways
  C. Elevator shafts
  D. RFID chokepoints
  E. Drywall offices
  A. Microwave ovens
  C. Elevator shafts

  B. Distributed Coordination Function (DCF)
  C. Frequency Shift Keying (FSK)
  D. Transmit Power Control (TPC)
  E. Radio Resource Management (RRM)
  F. Dynamic Frequency Selection (DFS)
  D. Transmit Power Control (TPC)
  F. Dynamic Frequency Selection (DFS)

• Question 29:

  What factors are likely to cause the greatest impact on the application layer throughput of an 802.11n client station in a 2.4 GHz HT BSS? (Choose three)

  A. Use of WEP or TKIP for encryption instead of CCMP
  B. Use of passphrase authentication instead of 802.1X/EAP authentication
  C. Increasing the beacon interval from 100 to 200 (TUs)
  D. RF interference from more than 10 nearby Bluetooth transmitters
  E. Increasing or decreasing the number of spatial streams in use by the client station and AP
  F. Configuring the AP to perform off-channel IDS scans for rogue devices for 50 ms out of every 20 seconds
  A. Use of WEP or TKIP for encryption instead of CCMP
  D. RF interference from more than 10 nearby Bluetooth transmitters
  E. Increasing or decreasing the number of spatial streams in use by the client station and AP
