Cisco 350-801 Online Questions & Answers

• Question 241:

  Which values must be enabled to set up QoS for video conferencing on a VoIP network?

  A. CS4 and DSCP 32
  B. AP41 and DSCP 34
  C. AF31 and DSCP 34
  D. CS3 and DSCP 24
  B. AP41 and DSCP 34

• Question 242:

  What are two access management mechanisms in Cisco Webex Control Hub? (Choose two.)

  A. multifactor authentication
  B. Active Directory synchronization
  C. attribute-based access control
  D. single sign-on with Google
  E. Client ID/Client Secret
  A. multifactor authentication
  B. Active Directory synchronization

  ---

  Explanation

  The two access management mechanisms in Cisco Webex Control Hub are multifactor authentication and Active Directory synchronization. Multifactor authentication is a security measure that requires users to provide two or more pieces of evidence to verify their identity. This can include something they know, such as a password, and something they have, such as a security token. Active Directory synchronization is a process that allows Cisco Webex Control Hub to automatically synchronize user accounts from an Active Directory domain. This can simplify user management and provide users with single sign-on access to Cisco Webex Control Hub and other applications.

• Question 243:

  An engineer is asked to implement on-net/off-net call classification in Cisco UCM.

  Which two components are required to implement this configuration? (Choose two)

  A. SIP trunk
  B. CTI route point
  C. route group
  D. route pattern
  E. SIP route patterns
  A. SIP trunk
  D. route pattern

• Question 244:

  A recent audit discovered incidents of toll fraud. Restrictions should include Cisco UCM class of service and supplementary services features.

  Which two actions in Cisco UCM prevent further toll fraud from happening? (Choose two.)

  A. Implement a class of restrictions on the gateway.
  B. Implement transformation pattern for all off-net calls.
  C. Set the service parameter to block off-net to off-net transfers.
  D. Restrict international patterns on SIP trunk CSS to the gateway.
  E. Set the call forward all CSS to restrict international patterns.
  C. Set the service parameter to block off-net to off-net transfers.
  E. Set the call forward all CSS to restrict international patterns.

• Question 245:

  Refer to the exhibit.

  

  An administrator is attempting to resolve a DTMF issue to a specific IVR and has supplied logs from the most recent issue.

  What is the cause and solution of the issue?

  A. The local endpoint supports RFC2833, and the IVR supports only KPML. Configure an MTP to resolve the DTMF mismatch.
  B. The local endpoint does not support RFC2833, and the IVR supports only RFC2833. Configure a transcoder to resolve the DTMF mismatch.
  C. The local endpoint does not support RFC2833, and the IVR supports only RFC 2833. Configure an MTP to resolve the DTMF mismatch.
  D. The local endpoint supports RFC2833, and the IVR supports only KPML. Configure a transcoder to resolve the DTMF mismatch.
  C. The local endpoint does not support RFC2833, and the IVR supports only RFC 2833. Configure an MTP to resolve the DTMF mismatch.

• Question 246:

  An engineer is configuring a Cisco Unified Border Element to allow the video endpoints to negotiate without the Cisco Unified Border Element interfering in the process.

  What should the engineer configure on the Cisco Unified Border Element to support this process?

  A. Configure pass-thru content sdp on the voice service.
  B. Configure a hardcoded codec on the dial peers.
  C. Configure a transcoder for video protocols.
  D. Configure codec transparent on the dial peers.
  A. Configure pass-thru content sdp on the voice service.

  ---

  Explanation

  You can use 'pass-thru content sdp', if you do not want to involve CUBE in the codec negotiation.

• Question 247:

  Which call flow matches traffic from a Mobile and Remote Access registered endpoint to central call control?

  A. Endpoint > Expressway-E > Expressway-C > Cisco Unified CM
  B. Endpoint > Expressway-E > Cisco Unified CM
  C. Endpoint > Expressway-C > Cisco Unified CM
  D. Endpoint > Expressway-C > Expressway-E > Cisco Unified CM
  A. Endpoint > Expressway-E > Expressway-C > Cisco Unified CM

• Question 248:

  A remote office has a less-than-optimal WAN connection and experiences packet loss, delay, and jitter.

  Which VoIP codec should be used in this situation?

  A. G.711ulaw
  B. iLBC
  C. G.722.1
  D. G.729A
  B. iLBC

  ---

  Explanation

  iLBC: iLBC provides audio quality between that of G.711 and G.729 at bit rates of 15.2 kbps (38-bytes or 20msec) and 13.3 kbps (50 bytes or 30 msec). iLBC handles lossy networks in better way than G729 because it treats each packet independently. G729 depends on the previous packet to handle packet loss, jitter and delay which doesn't tolerate well in lossy networks.

• Question 249:

  You are adding regions in Cisco Unified Communications Manager.

  Which codec(s) are selected when a call is placed if you set up the max audio bit rate to use 8 kbps?

  A. G.729
  B. G 729 and G.711ulaw
  C. G.711ulaw and G 711alaw
  D. G.722
  A. G.729

• Question 250:

  What is the purpose of a hybrid Local Gateway?

  A. to handle calls between Cisco UCM and Webex Calling
  B. to handle calls between the Public Switched Telephone Network and Webex Calling
  C. to handle calls between Webex Calling and Cisco Calling Plans
  D. to handle calls between Webex Calling and Cloud Connected PSTN
  B. to handle calls between the Public Switched Telephone Network and Webex Calling
