Cisco CCNP Collaboration 350-801 Questions & Answers

• Question 381:

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

• Question 382:

  A user reports transfer failure from an IP phone for calls received from a PSTN to another PSTN number. What is a reason for these failures?

  A. The IP phone is configured with the wrong region.

  B. The incoming calling search space of the SIP trunk does not include the partition of the line in the IP phone.

  C. The service parameter related to Offnet to Offnet Call Transfer is set to TRUE.

  D. The gateway is configured with the wrong device pool.

  Correct Answer: C

• Question 383:

  An engineer with ID012345678 must build an international dial plan in Cisco Unified Communications Manager. Which action should be taken when building a variable-length route pattern?

  A. reduce the T302 timer to less than 4 seconds

  B. configure single route pattern for international calls

  C. create a second route pattern followed by the # wildcard

  D. set up all international route patterns to 0.1

  Correct Answer: C

  When building a variable-length route pattern, you need to create a second route pattern followed by the # wildcard. This will allow the user to indicate the end of the number by dialing #. For example, if you want to create a route pattern for

  international calls, you would create a route pattern like this:

  9.011!#

  This route pattern will match any number that starts with 9.011, followed by any number of digits, and then ends with #.

  The other options are incorrect because:

  Configuring a single route pattern for international calls will not allow the user to indicate the end of the number.

  Setting up all international route patterns to 0.! will not allow the user to indicate the end of the number.

  Reducing the T302 timer to less than 4 seconds will not allow the user to indicate the end of the number.

• Question 384:

• Question 386:

  A present redundancy group is deployed, and an engineer with ID012345678 initiates a manual fallback. Which statement about Cisco Server Recovery Manager is true?

  A. disconnects all users that had been failed over, and the users must log in again.

  B. disconnects all users that had been failed over

  C. restarts critical on the secondary node

  D. restarts the Cisco Presence Engine

  Correct Answer: A

  Manual Failover, Fallback, and Recovery Use Cisco Unified Communications Manager Administration to initiate a manual failover, fallback, and recovery for IM and Presence Service nodes in a presence redundancy group. You can also initiate these actions from Cisco Unified Communications Manager or IM and Presence Service using the CLI. See the Command Line Interface Guide for Cisco Unified Communications Solutions for details. Manual failover: When you initiate a manual failover, the Cisco Server Recovery Manager stops the critical services on https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/im_presence/configAdminGuide/12_5_1_su2/cup0_b_config-and-admin-guide-1251su2/cup0_b_config-and-admin-guide-1251su2_chapter_0100.html

• Question 387:

  An engineer is notified that the Cisco TelePresence MX800 that is registered in Cisco Unified Communications Manager shows an empty panel, and the Touch 10 shows a corresponding icon with no action when pressed. Where does the engineer go to remove the inactive custom panel?

  A. The Software Upgrades page in CUCM OS Administration

  B. The In-Room Control Editor on the webpage of the MX800

  C. The phone configuration page in CUCM Administration

  D. The SIP Trunk Security Profile page in CUCM Administration

  Correct Answer: B

• Question 388:

  Regarding SIP integrations with Cisco Unified Communications Manager, if the Cisco Unity Connection is configured to listen for incoming IPv4 and IPv6 traffic, how should the addressing mode be set up in the Cisco Unity Connection?

  A. Set up is not required.

  B. Set up for each group to use IPv4 and IPv6.

  C. Set up media ports for each port group to use IPv4.

  D. Set up IPv4 and IPv6 in Cisco Unified CM.

  Correct Answer: B

  For SIP integrations with Cisco Unified CM, if Unity Connection is configured to listen for incoming IPv4 and IPv6 traffic, you can configure the addressing mode that Unity Connection uses for call control signaling for each port group to use either IPv4 or IPv6. (This mode is also used when connecting to a TFTP server.) In addition, you can configure the addressing mode that Unity Connection uses for media for each port group to use either IPv4 or IPv6.

• Question 389:

  Refer to the exhibit.

  

  A call is failing to establish between two SIP Devices The called device answers with this SOP. Which SDP parameter causes this issue?

  A. The payload for G.711ulaw must be 18.

  B. The calling device did not offer a ptime value.

  C. The media stream is set to sendonly.

  D. The RTP port is set to 0.

  Correct Answer: D

  The RTP port is used to send and receive media packets during a call. If the RTP port is set to 0, the called device will not be able to send or receive media packets, and the call will fail. The other options are not correct because:

  A. The calling device did not offer a ptime value: The ptime value is used to specify the amount of time between each media packet. If the calling device does not offer a ptime value, the called device will use the default value of 20 milliseconds. B. The media stream is set to sendonly: The media stream is set to sendonly when the called device is only able to send media packets, and not receive them. This is not a problem, and the call will still succeed.

  C. The payload for G.711ulaw must be 18: The payload for G.711ulaw is the type of media packet that is used. The payload must be set to 18 for G.711ulaw, but this is not a problem, and the call will still succeed.

• Question 390:

  Which recommendation is the best practice for marking video and voice media in a Cisco Unified Communications network?

  A. Voice Cos 5 (IP Precedence 6, PHB AF41, or DSCP 16) Video Cos 4 (IP Precedence 5, PHB EF, or DSCP 32)

  B. Voice Cos 6 (IP Precedence 4, PHB AF41, or DSCP 24) Video Cos 5 (IP Precedence 4, PHB EF, or DSCP 34)

  C. Voice Cos 5 (IP Precedence 2, PHB EF, or DSCP 48) Video Cos 4 (IP Precedence 4, PHB AF41, or DSCP 46)

  D. Voice Cos 5 (IP Precedence 5, PHB EF, or DSCP 46) Video Cos 4 (IP Precedence 4, PHB AF41, or DSCP 34)

  Correct Answer: D
