• Question 22:

  Which two statements about the Peer Firmware Sharing option for IP phone firmware distribution are true? (Choose two.)

  A. This option uses a parent-child hierarchy in which a firmware image is downloaded by a parent phone to up to three directly associated child phones.
  B. This option must be enabled on Cisco Unified Communications Manager service parameters for Cisco TFTP.
  C. This option mandates that the parent phone and child phones be identical, selected phone models.
  D. This option allows firmware transfers between phones in different subnets, as long as the round-trip delay is less than 5 milliseconds.
  E. This option uses a parent-child hierarchy that must be manually defined by the Cisco Unified Communications Manager administrator.
  F. This option allows falling back to the TFTP server in the Cisco Unified Communications Manager cluster.
  C. This option mandates that the parent phone and child phones be identical, selected phone models.
  F. This option allows falling back to the TFTP server in the Cisco Unified Communications Manager cluster.

  Peer Firmware Sharing works by setting up a parent-child hierarchy of the phones in which a firmware image is downloaded by the parent phone to a child phone. The advantage of using Peer Firmware Sharing is that instead of all phones individually retrieving a software image, they pass the image along from one phone to another phone on the same subnet.

  Advantage of PFS: Hierarchy is automatic One download per phone model on a subnet Uses TCP Fails back to TFTP Speeds up LAN upgrades Reduces TFTP CPU load during upgrade

• Question 23:

  Which two SCCP call signaling messages are initiated by Cisco Unified Communications Manager to an IP phone? (Choose two.)

  A. SoftKeyEvent
  B. CloseReceiveChannelAck
  C. CallState
  D. KeypadButton
  E. OpenReceiveChannel
  F. Offhook
  C. CallState
  E. OpenReceiveChannel

  ---

  Upon receiving an OpenReceiveChannelmessage, the IP phone selects the UDP port number it wants to use to receive RTP packets and reports this information to call manager. With the SCCP protocol architecture, the majority of the H.323 processing power resides in an H.323 proxy -- the Cisco CallManager. The end stations (IP phones) run the Skinny client, which consumes less processing overhead. The client communicates with CallManager using connection-oriented (TCP/IP-based) communication to establish a call with another H.323-compliant end station. Once Cisco CallManager has established the call, the two H.323 end stations use connectionless (UDP/IP-based) communication for audio transmissions.

• Question 24:

  A Cisco Unity Connection administrator receives a name change request from a voice-mail user, whose Cisco Unity Connection user account was imported from Cisco Unified Communications Manager. What should the administrator do to execute this change?

  A. Change the user data in the Cisco Unity Connection administration page, then use the Synch User page in Cisco Unity Connection administration to push the change to Cisco Unified Communications Manager.
  B. Change the user data in the Cisco Unified Communications Manager administration page, then use the Synch User page in Cisco Unity Connection administration to pull the changes from Cisco Unified CM.
  C. Change the user data in the Cisco Unified Communications Manager administration page, then use the Synch User page in Cisco Unified CM administration to push the change to Cisco Unity Connection.
  D. Change the user profile from Imported to Local on Cisco Unity Connection Administration, then edit the data locally on Cisco Unity Connection.
  E. Change the user data in Cisco Unity Connection and Cisco Unified Communications Manager separately.
  B. Change the user data in the Cisco Unified Communications Manager administration page, then use the Synch User page in Cisco Unity Connection administration to pull the changes from Cisco Unified CM.

  As we can see user are getting synch from call manager so we first have to change the details of user on call manager so that user will synch the changes from call manager.

• Question 25:

  Company ABC is planning to migrate from MCS-hosted Cisco Unified Communications Manager applications to Cisco UC on UCS B-Series servers. Which statement about installation media support is true for this migration?

  A. The install log can be written to a USB flash drive that is attached to the UCS server.
  B. The answer file that is generated by the Answer File Generator (platformConfig.xml) can be read from a USB flash drive to perform an unattended installation on the UCS server.
  C. The Cisco Music on Hold USB audio sound card can be mapped to a virtual USB port on a VMware virtual machine on the UCS server.
  D. The answer file that is generated by the Answer File Generator (platformConfig.xml) can be read from an FLP image that is mounted in a virtual floppy drive.
  E. The Cisco Music on Hold USB audio sound card can be mapped to a virtual serial port on a VMware virtual machine on the UCS server.
  D. The answer file that is generated by the Answer File Generator (platformConfig.xml) can be read from an FLP image that is mounted in a virtual floppy drive.

  Using the AFG will allow you to get this license mac before even touching the server. It is provided after filling in the main form of the AFG but it can also be found by looking at the last few lines of your platformconfig.xml file. Once you have the xml files, you will need to map those to the floppy drive of the VM (no usb support on the VM OVA). There are many ways to do this. I simply use a freeware virtual floppy app that I drop the platformconfig.xml file on and then copy the*.flp image out to the datastore. I'll end up with a directory on my datastore called AFG that has the host named *.flp images that I will use during install. It also serves as archival of these files in the event the server needs to be re-imaged. This is important because the license mac will change if every parameter is not entered exactly as it was prior. If the license mac changes, you will have to go through the process of requesting new license files to be generated.

• Question 29:

  Which description of how dialed numbers are recorded in the Call Detail Record in Cisco Unified Communications Manager is true?

  B. CDR records the dialed numbers after route pattern level digit manipulation.
  C. CDR records the dialed numbers prior to translation level digit manipulation.
  D. Client Matter Codes are not included in CDR for security reasons.

  B. CDR records the dialed numbers after route pattern level digit manipulation.

• Question 30:

  Refer to the exhibit.

  

  A customer has two Cisco Unified Communication manager 9.X clusters that serve the same location. An engineer has attempted to set up Enhanced Location call admission control so that any call within a site between phones on the two clusters do not decrement the available bandwidth to and from that site. However, the real time monitoring tool currently shows bandwidth being used from the site to Hub_none. When a call is placed between phones at the site, which action must be taken to correct this situation?

  A. The link between clusters must be a type of inter-cluster trunk instead of a sip trunk.
  B. The hub_none location must have a link configuration to the phantom location.
  C. The device pool names must match between clusters.
  D. The Hub_none location must have a link configured to the shadow location.
  E. The SIP trunks should be changed to use the shadow location.
  E. The SIP trunks should be changed to use the shadow location.
