One of your customers plans on providing wireless coverage to a warehouse facility. After performing an initial walkthrough, you collect the following information:

What would be your recommendation to provide coverage to the central area (indicated by a blue circle) of the warehouse?

• A.  Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.
• B.  Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.
• C.  Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from the switch.
• D.  In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as possible to the central area of the warehouse.

You told your customer that multipath fading may be mitigated simply by moving one or both of the receiver's antennas a little bit, usually by one to four wavelengths away from its original position. Your customer is prepared to make the change, but does not know the wavelength for 802.11a.
What is the approximate wavelength of an 802.11a radio wave?

• A.  15.24 cm (6 inches)
• B.  45 cm (17.71 inches)
• C.  12 cm (4.72 inches)
• D.  5.5 cm (2.16 inches)
• E.  58 cm (22.83 inches)

Multicast video applications typically require special treatment on the Wi-Fi network due to the nature of multicast traffic. Many vendors implement proprietary multicast-to-unicast conversion for this reason.
Which of the following is NOT a valid reason for special unicast conversion of downlink multicast traffic?

• A.  Multicast traffic must always be transmitted via omnidirectional antennas.
• B.  Frames with a group receiver address must always be sent at a rate in the Basic Rate Set.
• C.  Group addressed downlink frames are not acknowledged on the wireless medium.
• D.  In QoS WLANs, multicast traffic is always assigned to the best effort (AC_BE) transmit queue.

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users are highly transient (frequently come and go). With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client associations. The DHCP server is a Windows Server 2008 machine. Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?

• A.  Set the 802.1X re-authentication timer to 10 minutes
• B.  Set the maximum client limit per radio to 64
• C.  Enable WLAN Controller DHCP relay
• D.  Set the DHCP lease for this pool to 20 minutes
• E.  Set the inactive wireless client timeout (client age-out) to 5 minutes
• F.  Set the AES rekey interval to 5 minutes
• G.  Enable mandatory admission control
• H.  Set the RTS threshold to 2346 bytes

What exhibit reflects the recommended life-cycle steps for successfully designing and deploying an enterprise WLAN from start to finish? (Choose 2)

• A.  Solution 5
• B.  Solution 1
• C.  Solution 4
• D.  Solution 3
• E.  Solution 2
