Question No: 441 – (Topic 4)

Which SIP request is used by Cisco Unified Communications Manager to signal DND status changes to a Cisco 9971 IP Phone?

  1. OPTIONS

  2. NOTIFY

  3. INFO

  4. REFER

  5. UPDATE

Answer: D Explanation:

Cisco Unified Communications Manager supports Do Not Disturb that a SIP device initiates or that a Cisco Unified Communications Manager device initiates. A DND status change gets signaled from a SIP device to Cisco Unified Communications Manager by using the SIP PUBLISH method (RFC3909). A DND status change gets signaled from a Cisco Unified Communications Manager to a SIP device by using a dndupdate Remote-cc REFER request. Cisco Unified Communications Manager can also publish the Do Not Disturb status for a device, along with the busy and idle status for the device.

Question No: 445 – (Topic 4)

Which method does a Cisco Unified 9971 phone use to send keep-alive messages to Cisco Unified Communications Manager?

  1. SIP NOTIFY with Event set to keep-alive

  2. SIP OPTIONS

  3. SIP REGISTER with Expires set to zero

  4. SCCP StationRegister

  5. SCCP StationServerReq

Answer: C Explanation:

Phone registers with primary and establishes keepalive connection with secondary. Expires = 0 keepalive mechanism allows Cisco SIP Phones to more closely resemble the failover / fallback behavior of SCCP.

Question No: 446 – (Topic 4)

Which device is the initiator of a StationD message in a Cisco Unified Communications Manager SDI trace?

  1. SCCP IP phone

  2. SIP IP phone

  3. Cisco Unified Communications Manager

  4. MGCP analog gateway

  5. digital voice gateway

Answer: C Explanation:

All messages to and from a skinny device are preceded by either the words StationD or StationInit. StationD messages are sent from call manager to IP phone. Skinny message transmission such as this between the IP phone and CallManger occurs for every action undertaken by the IP phone, includinginitialization, registration, on-hook, off-hook, dialing of the digits, key press on the phone, and so much more.

Question No: 447 – (Topic 4)

Which Cisco Unified Communications Manager partition will be associated with a directory URI that is configured for an end user with a primary extension?

  1. null

  2. none

  3. directory URI

  4. default

  5. any partition that the Cisco Unified Communications Manager administrator desires

Answer: C Explanation:

Cisco Unified Communications Manager supports dialing using directory URIs for call addressing. Directory URIs look like email addresses and follow the username@host format where the host portion is an IPv4 address or a fully qualified domain name. A directory URI is a uniform resource identifier, a string of characters that can be used to identify a directory number. If that directory number is assigned to a phone, Cisco Unified Communications Manager can route calls to that phone using the directory URI. URI dialing is available for SIP and SCCP endpoints that support directory URIs.

Question No: 448 – (Topic 4)

Which two applications can connect directly with a Cisco Unified Communications Manager Session Management Edition cluster? (Choose two.)

  1. Cisco Unity

  2. Cisco Unified Meeting Place Express

  3. Cisco Unified Contact Center Enterprise

  4. Cisco Unified Contact Center Express

  5. Cisco Unified Communications Manager Attendant Console

  6. Cisco Emergency Responder

Answer: A,B Explanation:

The deployment of a Unified CM Session Management Edition enables commonly used applications such as conferencing or videoconferencing to connect directly to the Session Management cluster, thus reducing the overhead of managing multiple trunks to leaf

systems. Cisco Unity or other voicemail systems can be deployed at all sites and integrated into the Unified CM cluster.

Question No: 449 – (Topic 4)

Which statement describes the Maximum Serving Count service parameter of the Cisco TFTP service on Cisco Unified Communications Manager?

  1. It specifies the maximum number of files in the TFTP server disk storage.

  2. It specifies the maximum number of TFTP client requests to accept and to serve files at a given time.

  3. It specifies the maximum file support by the Cisco TFTP service.

  4. It specifies the maximum file counts, in cache as well as in disk, that are supported by the Cisco TFTP service.

  5. It specifies the maximum number of TFTP client requests to accept and to serve files in a 120-minute window.

Answer: B Explanation:

This parameter specifies the maximum number of client requests to accept and to serve files at a time. Specify a low value if you are serving files over a low bandwidth connection. You can set it to a higher number if you are serving small files over a large bandwidth connection and when CPU resources are available, such as when no other services run on the TFTP server. Use the default value if the TFTP service is run along with other Cisco CallManager services on the same server. Use the following suggested values for a dedicated TFTP server: 1500 for a single-processor system and 3000 for a dual-processor system. If the dual-processor system is running Windows 2000 Advanced Server, the serving count can be up to 5000.

This is a required field.

->Default: 200.

->Minimum: 1.

->Maximum: 5000.
