• Question 391:

  You are trying to connect a Cisco wireless phone to your network. Based on the device manual, Admission Control must be enabled on the wireless network for the device to connect. When you enable Admission Control, you get an error

  message and the operation is aborted.

  What is the root of the problem?

  A. Admission Control is not supported in all radios. Verify that the wireless phone is connecting to the correct radio.
  B. You cannot enable Admission Control if the radio is enabled.
  C. The wireless phone is incompatible with the wireless infrastructure.
  D. Admission Control is an unsupported feature of Cisco APs unless the client supports CCXv5.
  B. You cannot enable Admission Control if the radio is enabled.

• Question 392:

  Your customer wants to configure LSCs and asks for specific information about which number to configure in the text box right next to the "Number of Attempts" .Which statement is true?

  A. The default number of attempts is 100.
  B. A value of 2 means that if an AP fails to join the Cisco WLC using an LSC, the AP attempts to Join the Cisco WLC using the default certificate
  C. A value of 255 means that if an AP fails to join the Cisco WLC using an LSC, the AP does not attempt to join the Cisco WLC using the default .
  D. A value of 3 means that if a user fails to authenticate, the user is disconnected after three retries.
  B. A value of 2 means that if an AP fails to join the Cisco WLC using an LSC, the AP attempts to Join the Cisco WLC using the default certificate

• Question 393:

  A. New mobility is supported.
  B. WGB and the clients associated to the WGB need to be re-associated post switchport.
  C. All clients are synced between active and standby WLC.
  D. For SSO to work, both WLCs must have a high availability SKU UDI.
  B. WGB and the clients associated to the WGB need to be re-associated post switchport.

• Question 394:

  Which two statements about deploying a mesh network by MAPs and RAPs are true on AireOS 8.0?(choose two)

  A. The three main types of mesh type under the neighbor information are neighbored, parent and child. For types default neighbor and default child default is used when the neighbor BGN is not known of different from the current AP BGNif the strict matching BGN features is disabled.
  B. The backhaul client access feature cannot be enabled on a RAP that is RAP does not allow clients on its 802.11a radio
  C. To allow relaying traffic to and from the Ethernet port of a MAP,the Ethernet bridging feature must be enabled on the map
  D. A map of rap must be authorized by either PSK or EAP before joining a controller in bridge mode.

• Question 395:

  A customer deploys a new WLAN that has 60 APs and 10 SSIDs. The customer uses a 40-MHz channel design for a 5-GHz WLAN that supports 10 nonoverlapping channels. The customer uses a mandatory Basic rate of 12 Mbps on the 5GHz WLAN and 6 Mbps on the 2.4-GHz WLAN. After the deployment, the customer discovers that the 2.40-GHz frequency band is almost completely unusable and that the 5-GHz frequency is degraded.

  Which two options are possible ways to resolve the issues? (Choose two.)

  A. Change Channel Width to 20 MHz for the 5-GHz radio.
  B. Reduce the number of SSIDs to four or less.
  C. Increase the Beacon interval from 100 to 200 ms.
  D. Decrease the Beacon interval from 100 to 50 ms.
  E. Set the mandatory Basic rate to 18 Mbps on 5 GHz and 24 Mbps on 2.4 GHz for the RF profile.
  A. Change Channel Width to 20 MHz for the 5-GHz radio.
  B. Reduce the number of SSIDs to four or less.

• Question 396:

  

  Refer to the exhibit. What is the best way to resolve this issue?

  A. Install a server certificate signed by a well-know public CA on the WLC.
  B. Disable certificate checks on the client.
  C. Install a server certificate signed by a well-known public CA on the Radius Server.
  D. Use the certificate authority on the Cisco Identity Services Engine.
  C. Install a server certificate signed by a well-known public CA on the Radius Server.
