  B. AP
  C. Cisco WLC
  D. Cisco MSE
  E. Cisco WCS
  F. Cisco WCS is not enabled.
  B. AP
  D. Cisco MSE

• Question 456:

  Which software you can use to do both active and passive site surveys?

  A. Fluke networks Airmagnet Pro
  B. Fluke networks Airmagnet lite
  C. Cisco spectrum analyzer
  A. Fluke networks Airmagnet Pro

• Question 457:

  Refer to the exhibit.

  

  A network administrator is attempting to connect to the GUI of a WLC with interfaces as shown. Which IP address should the network administrator use?

  A. 192.168.0.2
  B. 192.168.1.2
  C. 192.168.2.2
  D. 192.168.3.2
  E. 192.168.4.2
  B. 192.168.1.2

• Question 458:

  A company has all IEEE 802.11a/802.11g devices; however, its network administrator recommends installing 802.11n access points to provide greater performance. Which feature on an 802.11n AP provides better performance to legacy devices?

  A. channel aggregation
  B. transmit beam-forming
  C. maximal-ratio combining
  D. spatial multiplexing
  B. transmit beam-forming

• Question 459:

  Which two statements about the requirements to configure inter-controller roaming are true? (Choose two.)

  A. The same mobility domain names are configured across controllers.
  B. The same RF group names are configured across controllers.
  C. The same controller hardware version is configured across controllers.
  D. The same AP manager interface is configured across controllers.
  E. The same virtual interface is configured across controllers.
  F. The same controller software version is configured across controllers.
  A. The same mobility domain names are configured across controllers.
  E. The same virtual interface is configured across controllers.

  ---

  All controllers must be configured with the same mobility group name. All controllers must be configured with the same virtual interface IP address. If necessary, you can change the virtual interface IP address by editing the virtual interface name on the Controller > Interfaces page.

  If all the controllers within a mobility group are not using the same virtual interface, inter-controller roaming may appear to work, but the handoff does not complete, and the client loses connectivity for a period of time. http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-0/configuration/guide/c70/c70mobil.html

• Question 460:

  Which device divides a signal between two antennas?

  A. splitter
  B. lightening arrestor
  C. attenuator
  D. amplifier
  A. splitter

  ---

  A splitter causes insertion loss and divides available power between two antennas.
