Cisco 400-351 Online Questions & Answers

• Question 311:

  802.11k and 802.11k-enabled client devices send a request for a list of neighbor APs (a neighbor list) from the APs they are currently associated with. What is this 802.11management frame also known as?

  A. association response
  B. association packet
  C. beacon frame
  D. action packet
  D. action packet

• Question 312:

  In order to provide end-to-end QoS, how to send traffic classification information between the LWAPP AP and the WLAN Controller?

  A. LWAPP APs map the WMM CoS values of the client traffic to the Ethernet frames and the CoS value of the Ethernet frames sent to the AP to the WMM access category. The switch upstream from the AP is responsible for converting between 802.1D classification and DSCP
  B. LWAPP packets from the controller and the AP are marked by DSCP based on the DSCP of the tunneled traffic. This DSCP is converted to a CoS by a table in the AP. The access category used for each frame depends on the table CoS and QoS profile of the WLAN
  C. There is no end-to-end QoS, only WMM on the WLAN. This is all that is required, because campus networks typically have greater than 1 Gb/s backbones and WLANs operate at only 11 or 54 Mb/s
  D. The WMM CoS values are carried within the LWAPP tunnels and translated from CoS to DSCP to ensure that the correct priority is given to different LWAPP packets
  B. LWAPP packets from the controller and the AP are marked by DSCP based on the DSCP of the tunneled traffic. This DSCP is converted to a CoS by a table in the AP. The access category used for each frame depends on the table CoS and QoS profile of the WLAN

• Question 313:

  What are the three fundamental properties that are provided by the antenna of an AP? (Choose three.)

  A. frequency
  B. gain
  C. dB loss
  D. polarization
  E. direction
  F. modulation
  B. gain
  D. polarization
  F. modulation

• Question 314:

  A user is presented with the underlying hardware and software needed to develop and offer applications via the Internet from a cloud service provider. Which cloud model is this user consuming?

  A. Software as a Service
  B. Platform as a Service
  C. Application as a Service
  D. Infrastructure as a Service
  A. Software as a Service

• Question 316:

  

  Refer to the exhibit. Which option describes what this sequence of commands achieves on a Cisco Autonomous AP?

  A. This example shows how to permit SNMP access to all objects with read-only permission to only those three specific IP addresses using the community string public. The access point also sends config traps to the hosts 192.180.1.111 and 192.180.1.33 using SNMPv1 and to the host 192.180.1.27 using SNMPv2C. The community string public is not sent with the traps because is the default community value.
  B. This example shows how to permit SNMP access to all objects with read-only permission to only those three specific IP addresses using the community string public. The access point also sends config traps to the hosts 192.180.1.111 and 192.180.1.33 using SNMPv1 and to the host 192.180.1.27 using SNMPv2C. The community string public is not sent with the traps.
  C. This example shows how to permit any SNMP manager to access all objects with read- only permission using the community string public. The access point also sends config traps to the hosts 192.180.1.111 and 190.180.1.33 using SNMPv1 and to the host 192.180.1.27 using SNMPv2C. The community string public is not sent with the traps as this is the default community value.
  D. This example shows how to permit any SNMP manager to access to all objects with read-only permission using the community string public. The access point also sends config traps to the hosts 192.180.1.111 and 190.180.1.33 using SNMPv1 and to the host 192.180.1.27 using SNMPv2C. The community string public is sent with the traps.
  D. This example shows how to permit any SNMP manager to access to all objects with read-only permission using the community string public. The access point also sends config traps to the hosts 192.180.1.111 and 190.180.1.33 using SNMPv1 and to the host 192.180.1.27 using SNMPv2C. The community string public is sent with the traps.

• Question 317:

  You have configured your guest SSID to use MAC-filtering Layer 2 authentication. Under the Cisco Unified Wireless Guest Solution using auto-anchor, which component is responsible for communications with RADIUS servers?

  A. Prime Infrastructure
  B. Foreign WLC
  C. Anchor WLC
  D. Lightweight AP
  C. Anchor WLC

• Question 318:

  

  Refer to the exhibit. You are the network administrator at a corporation and you are trying to troubleshoot a Fast BSS transition issue for a client. You have received the snapshot of the packet capture. Based on your analysis of this packet capture, which statement is true?

  A. The packet capture shows the Fast BSS transition over the air.
  B. The packet capture is for the initial association of the client with an AP supporting 802.11r-based Fast BSS transition.
  C. The packet capture shows Fast BSS transition over the DS, authentication packets are sent at basic rate of 36 Mbps.
  D. The packet capture shows that client cannot use any Fast BSS transition methods.
  B. The packet capture is for the initial association of the client with an AP supporting 802.11r-based Fast BSS transition.

• Question 319:

  Which one of the following commands could limit WLC output from subsequent debug commands to show only information associated with a specific wireless client device that has the MAC address 00:0c:41:07:33:a6?

  A. Debug mobility addr 00:0c:41:07:33:a6 enable
  B. Debug mac addr 00:0c:41:07:33:a6
  C. Debug mac addr 00-0c-41-07-33-a6 enable
  D. Debug mobility addr 00:0c:41:07:33:a6
  B. Debug mac addr 00:0c:41:07:33:a6
