• Question 11:

  In an 802.11n WLAN with a heterogeneous set of associated client devices including 802.11b, 11g, and 11n, what HT protection mode will the BSS use?

  A. Mode 0: No protection mode (Greenfield)
  B. Mode 1: Nonmember protection mode
  C. Mode 2: 20 MHz protection mode
  D. Mode 3: Non-HT mixed mode
  D. Mode 3: Non-HT mixed mode

• Question 12:

  Given:

  The center frequency of channel 1 in the 2.4 GHz ISM band is 2.412 GHz (2412 MHz).

  What is the center frequency of channel 2?

  A. 2.413 GHz
  B. 2.417 GHz
  C. 2.422 GHz
  D. 2.432 GHz
  E. 2.437 GHz
  B. 2.417 GHz

• Question 13:

  The client devices that connect to your network include a mix of dual-band 802.11n, single-band 802.11b/ g, and some 802.11a/g. Your access points are configured with the same SSID on both the 2.4 and 5 GHz bands. The APs are also configured to prioritize client connectivity to 5 GHz. How does an AP perform band steering to encourage clients to use 5 GHz?

  A. When the client sends a probe request in the 2.4 GHz band, the AP may reply with information about the 5 GHz BSS.
  B. The AP may ignore the initial probe requests or 802.11 authentication requests sent in the 2.4 GHz band by dual-band clients
  C. The AP may allow an 802.11 association with the client in the 2.4 GHz band, then send unicast channel switch announcements to the client announcing the 5 GHz channel as the new channel.
  D. After receiving probe request frames from the same client in both bands, the AP may send an association request frame to the client in the 5 GHz band.
  E. The AP may allow an 802.11 association with the client in the 2.4 GHz band, then the AP may perform a transparent client handoff by transferring the client's MAC address to the 5 GHz radio.
  B. The AP may ignore the initial probe requests or 802.11 authentication requests sent in the 2.4 GHz band by dual-band clients

• Question 14:

  Which features are incorporated in the 802.11-2007 specification and are recommend for robust WLAN client security? (Choose 2)

  A. SSID hiding
  B. CAPWAP with DTLS
  C. 802.1X/EAP
  D. CCMP cipher suite
  E. IPSec VPN
  F. MAC address whitelists
  C. 802.1X/EAP
  D. CCMP cipher suite

• Question 15:

  What type of RF transmitter is shown in both of the spectrum analysis exhibits?

  

  

  A. Military radar
  B. Bluetooth mouse
  C. Microwave oven
  D. Wireless video camera
  E. WIPS sensor
  D. Wireless video camera

• Question 16:

  What problems may exist for a multiple channel architecture (MCA) WLAN when its APs are all operating at full power (typically 100mW)? (Choose two)

  A. Wi-Fi enabled voice handsets with low transmit power can experience asynchronous downlink and uplink performance.
  B. WLAN client stations can experience the hidden node problem when located near each other within the same cell.
  C. The mismatched power between WLAN client stations and APs violates regulatory and IEEE signal quality requirements.
  D. Cell size may be too large, causing co-channel interference to adjacent cells and reducing system capacity.
  E. APs operating in the 2.4 GHz band would prevent microwave ovens and analog video cameras from functioning.
  A. Wi-Fi enabled voice handsets with low transmit power can experience asynchronous downlink and uplink performance.
  D. Cell size may be too large, causing co-channel interference to adjacent cells and reducing system capacity.

• Question 17:

  How is throughput capacity scaled in a single channel architecture (SCA) WLAN system?

  A. By increasing transmit power and placing APs that are on a single channel farther from one another.
  B. By adding more SSIDs to existing APs to spread users across different contention domains.
  C. By adding APs to increase the number of non-overlapping channel layers.
  D. By using downlink data compression and uplink flow control at the AP.
  E. By using a single 802.11n radio to transmit simultaneous downlink data streams to different users.
  C. By adding APs to increase the number of non-overlapping channel layers.

• Question 18:

  What is the purpose of the WLAN component shown in the exhibit?
