Cisco 300-370 Online Questions & Answers

• Question 51:

  Refer to the exhibit.

  

  A VoWLAN has been deployed at a customer site, and users report that audio is choppy in some areas. The exhibit captures a voice exchange between one phone that is associated to the AP at the end of the corridor (172.31.255.101) and another phone that is positioned in a conference room nearby. Which action enhances the voice application quality of experience?

  A. Change the basic rate configuration on the WLC to include 54 Mbps.
  B. Change the WLAN QoS profile to platinum.
  C. Decrease the AP power level.
  D. Disable higher data rates on the controller
  A. Change the basic rate configuration on the WLC to include 54 Mbps.

• Question 52:

  Which channel width is the maximum that can be obtained by bonding two 802.11ac subchannels according to US regulations?

  A. 160 MHz
  B. 120 MHz
  C. 84 MHz
  D. 240 MHz
  A. 160 MHz

  ---

  To increase throughput, 802.11ac introduces two new channel widths. All 802.11ac devices are required to support 80 MHz channels, which doubles the size of the spectral channel over 802.11n. It further adds a 160 MHz channel option for

  even higher speeds. Due to the limitations of finding contiguous 160 MHz spectrum, the standard allows for a 160 MHz channel to be either a single contiguous block or two noncontiguous 80 MHz channels.

• Question 53:

  Clients are failing EAP authentication. A debug shows that an EAP handshake started and the clients are then de-authenticated. Which two issues can cause this problem? (Choose two.)

  A. The clients are configured for machine authentication, but the RADIUS server is configured for user authentication.
  B. The WLC has not been added to the RADIUS server as a client.
  C. The WLC certificate has changed.
  D. The shared secret of the WLC and RADIUS server do not match.
  E. The WLAN is not configured for the correct EAP supplicant type.
  B. The WLC has not been added to the RADIUS server as a client.
  E. The WLAN is not configured for the correct EAP supplicant type.

• Question 54:

  A WLC receives a coverage hole detection alert from an AP.

  What two conditions must occur for the controller to dynamically mitigate the situation? (Choose two.)

  A. The AP serving the troubled client must currently have a power level 2 or lower.
  B. The client must be able to dynamically raise its power level to match the new AP power.
  C. The AP must be RF visible to additional APs on the other side of the coverage hole for calibration.
  D. The client must have WMM-PS disabled to allow for the increased power usage.
  E. The AP serving the troubled client must currently have a power level higher than 2.
  A. The AP serving the troubled client must currently have a power level 2 or lower.
  B. The client must be able to dynamically raise its power level to match the new AP power.

• Question 55:

  You have observed that the legacy 802.11a/g clients on your wireless network are often rate shifting to the next lower rate.

  Which functionality must you turn on to help prevent this rate shift and avoid the performance impact?

  A. ClientLink
  B. BandSelect
  C. CleanAir
  D. VideoStream
  C. CleanAir

• Question 56:

  DRAG DROP

  Drag and drop the discovery type on the left onto its discovery method on the right.

  Select and Place:

  

  

• Question 57:

  Which statement about the usage of the debug command in a Cisco Unified Wireless Network is true?

  A. Debug is enabled until manual shut off.
  B. Debug is a message logging severity 7.
  C. Debug is a restricted command and is not available in the AP CLI.
  D. Debug is available on the WLC serial console and web interface.
  B. Debug is a message logging severity 7.

• Question 58:

  An engineer is troubleshooting client issues and has found that DHCP proxy is enabled on the Cisco WLC by default. The Cisco WLC unicasts the packet to the DHCP server on the WLAN, but the DHCP server does not support the DHCP proxy. Which action fixes this issue?

  A. Disable DHCP proxy on the Cisco WLC.
  B. Ensure that the DHCP clients are directly connected to the interface of the server.
  C. Ensure that the switch ports that are connected to the Cisco WLC and the DHCP server are configured as a trunk.
  D. Ensure that the IP subnet of the WLAN is defined on the DHCP server.
  D. Ensure that the IP subnet of the WLAN is defined on the DHCP server.

• Question 59:

  A Cisco WLC v7.0 is not seeing an AP join. Which starting prefix debug command can help determine a combination of discovery/join and DHCP process status?

  A. debug capwap events - from Cisco WLC
  B. debug capwap events - from the AP
  C. debug ip udp - from Cisco WLC
  D. debug ip udp - from the AP
  D. debug ip udp - from the AP

• Question 60:

  A client is failing PEAP authentication and a debug shows the server is sending an Access-Reject message.

  Which action must you take to resolve authentication?

  A. Verify that the user is using the same password that is on the server.
  B. Verify that the user account is the same in the client certificate.
  C. Verify that the validate server certificate on the client is disabled.
  D. Verify that the client certificates are from the proper CA and server certificate.
  A. Verify that the user is using the same password that is on the server.
