  1. 1The IEEE 802.11n standard provides 40-MHz channels, improved MAC efficiency, and MIMO.
    Which three elements define the 802.11n implementation of MIMO? (Choose three.)
    1. Achannel bonding
    2. Bdynamic frequency selection
    3. Cmaximal ratio combining
    4. Dpacket aggregation
    5. Espatial multiplexing
    6. Ftransmit beam forming
  2. 2Which two statements about WiMAX technology are true? (Choose two.)
    1. AWiMAX is defined by 802.11i
    2. BTypically, fixed WiMAX networks have a higher-gain directional antenna installed near the
      client
    3. CWiMAX is capable of working as a long-range system over several miles.
    4. DWiMAX works only for licensed frequencies.
  3. 3Which governing body analyzes the applications and environments in which wireless networks
    are used?
    1. AEIRP
    2. BETSI
    3. CFCC
    4. DIEEE
    5. EWiFi Alliance
  4. 4Which description best describes upfade in a multipath environment?
    1. AIn this situation, multiple signal paths are not sent at exactly the same time. The receiver
      receives a positive crest on the primary signal and a negative crest on the secondary signal.
    2. BIn this situation, the multiple signal paths are distorted and difficult to understand.
    3. CIn this situation, the multiple signal paths are weaker than they should be because the
      signals are out of phase with each other
    4. DIn this situation, the signal is stronger than it should be because multiple signal paths are
      received twice at exactly the same time, which results in the multiple signals being in-phase.
  5. 5A controller is connected to a Cisco Catalyst switch. The switch port configuration looks like this:
    interface GigabitEthernet 1/0/10
    switchport
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 1,20,30,50
    switchport trunk native vlan 20
    switchport mode trunk
    Which controller CLI command assigns its management interface to the native VLAN interface of
    the Cisco Catalyst switch?
    1. Aconfig interface vlan management 0
    2. Bconfig interface vlan management 1
    3. Cconfig interface vlan management 20
    4. D. config interface vlan management 30
    5. Econfig interface vlan management 50
  6. 6Which statement about an infrastructure basic service set is true according to IEEE 802.11
    specifications?
    1. AThe set also is called an ad hoc network
    2. BThe BSSID is generated from the first wireless client that starts up in the IBSS.
    3. CThe set enables the use of ESS.
    4. DNo signals are relayed from one client to another client.
  7. 7Which two factors must be considered when evaluating an RF interferer for severity?
    (Choose two.)
    1. Adistance from the AP
    2. BdBm
    3. Cthe type of security crack being used
    4. Dduty cycle
    5. Enumber of interfering IP stations in the cell
    6. Fduplicate SSID
  8. 8Which two items are needed to discover the IP address of a new Cisco Aironet 1260 autonomous
    AP that just finished booting? (Choose two.)
    1. Ausername = "cisco" and password = "cisco"
    2. Busername = "Admin" and password = "Cisco"
    3. Cusername=Cisco and password=Cisco
    4. Dshow int vlan1
    5. Eshow int bvi1
    6. Fshow int gigabitethernet0
    7. Gshow int radio0-802.11n
    8. Hshow int radio1-802.11n
  9. 9Which statement correctly describes the procedure for a lightweight AP to successfully establish
    a connection to a controller?
    1. AThe AP authenticates the received Cisco WLC certificate as valid. The AP then sends its
      certificate to the controller.
    2. BThe AP sends its certificate to the controller. The AP then authenticates the received Cisco
      WLC certificate as valid.
    3. CThe AP sends its certificate to the RADIUS server. The AP then authenticates the controller
      certificate as valid.
    4. D. The AP sends its certificate to the RADIUS server. The AP then authenticates the RADIUS certificate as valid.
    5. EThe AP authenticates the received RADIUS server certificate as valid. The AP then sends its
      certificate to the RADIUS server
    6. FThe AP authenticates the received RADIUS server certificate as valid. The AP then sends its
      certificate to the controller
  10. 10Which two statements about the requirements to configure inter-controller roaming are true?
    (Choose two.)
    1. AThe same mobility domain names are configured across controllers.
    2. BThe same RF group names are configured across controllers.
    3. CThe same controller hardware version is configured across controllers
    4. DThe same AP manager interface is configured across controllers.
    5. EThe same virtual interface is configured across controllers.
    6. FThe same controller software version is configured across controllers.
