• Question 183:

  Which two responses from a SIP device, which is the only remote destination on a Cisco Unified Communications Manager SIP trunk with OPTIONS ping enabled, cause the trunk to be marked as "Out of Service"? (Choose two.)

  A. 503 Service Unavailable
  B. 408 Request Timeout
  C. 505 Version Not Supported
  D. 504 Server Timeout
  E. 484 Address Incomplete
  F. 404 Not Found
  A. 503 Service Unavailable
  B. 408 Request Timeout

  ---

  The remote peer may be marked as Out of Service if it fails to respond to OPTIONS, if it sends 503 or 408 responses, or if the Transport Control Protocol (TCP) connection cannot be established. If at least one IP address is available, the trunk is In Service; if all IP addresses are unavailable, the trunk is Out of Service.

• Question 184:

  You have implemented 5-digit forced authorization codes to all international route patterns on Cisco Unified Communications Manager. Your users report that after entering the FAC codes, they must wait for more than 10 seconds before the call is routed.

  Which procedure eliminates the wait time?

  A. Check and eliminate any existing route patterns that overlap with the international route pattern.
  B. Go to the Cisco Unified Communications Manager Service Parameters and reduce the T-304 number to 5000 milliseconds.
  C. Request your long distance telephone service provider to reduce the call setup time to 5 seconds.
  D. Configure a # (hash) sign to the end of the forced authorization codes to signal the end of dialing.
  E. Educate the users to press # (hash) after entering the forced authorization codes.
  E. Educate the users to press # (hash) after entering the forced authorization codes.

  ---

  Because it immediately stops taking digits and route the digits to CUCM, otherwise the call occurs after the interdigit timer expire which is 15 seconds by default.

• Question 185:

  Which Cisco Unified CM service is responsible for writing Call Management Records into the CDR Analysis and Reporting database?

  A. Cisco CDR Agent
  B. Cisco CAR DB
  C. Cisco CDR Repository Manager
  D. Cisco CAR Scheduler
  E. Cisco Extended Functions

• Question 186:

  Which external database software is required for the Cisco IM and Presence compliance feature?

  A. MySQL
  B. EnterpriseDB
  C. MSSQL
  D. SQLite
  E. PostgreSQL
  E. PostgreSQL

  ---

  The following Cisco Unified Presence features require an external database:

  Permanent Group Chat feature ?Cisco Unified Presence supports two types of group chat, temporary (ad-hoc) chat and permanent chat. You do not require an external database for temporary chat to work. However, if you require permanent

  chat rooms on Cisco Unified Presence, you must configure an external database.

  Instant Messaging Compliance - If you deploy the native Message Archiver (MA) component on Cisco Unified Presence for compliance logging, you require an external database.

  Requirements for Configuring an External Database

  Hardware requirements:

  A remote server on which you install the PostgreSQL database(s).

  Software requirements:

  Cisco Unified Presence, release 8.x.

  PostgreSQL database, versions 8.3.x through 9.1.1

  You can install the PostgreSQL database on either a Linux or a Windows operating system. See the PostgreSQL documentation for details on the supported operating systems and platform requirements.

• Question 187:

  A collaboration engineer is designing a Cisco Unity Connection network for a large client running 10 x. The client has 12 locations, each with their own Cisco Unity Connection cluster. Which two designs are valid? (Choose two)

  A. full-mesh topology with HTTPS Networking
  B. six clusters each in two full-mesh Unity Connection Digital Networks connected with VPIM.

  D. a 10-cluster Unity Connection Digital network connected to a 2-cluster HTTPS network
  E. hub-and-spoke topology with HTTPS Networking
  F. full-mesh topology with Unity Connection Digital Networking

• Question 188:

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

  A. It specifies the maximum number of files in the TFTP server disk storage.
  B. It specifies the maximum number of TFTP client requests to accept and to serve files at a given time.
  C. It specifies the maximum file support by the Cisco TFTP service.
  D. It specifies the maximum file counts, in cache as well as in disk, that are supported by the Cisco TFTP service.
  E. It specifies the maximum number of TFTP client requests to accept and to serve files in a 120-minute window.
  B. It specifies the maximum number of TFTP client requests to accept and to serve files at a given time.

  ---

  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.

• Question 189:

  In Key Press Markup Language, which SIP request is used to deliver the actual DTMF digits?

  A. SUBSCRIBE
  B. INFO
  C. NOTIFY
  D. INVITE
  E. ACK

  KPML procedures use a SIP SUBSCRIBE message to register for DTMF digits. The digits themselves are delivered in NOTIFY messages containing an XML encoded body.

• Question 190:

  Which two statements about using the Load Server option for IP phone firmware distribution are true? (Choose two.)

  B. This option must be enabled on Cisco Unified Communications Manager service parameters for Cisco TFTP.
  C. Phone firmware must be manually copied to any applicable load servers.
  D. The load server will not function if its IP address is not in the same subnet as the IP phones.
  E. This option is only available for newer IP phone models.
  F. This option does not accommodate falling back to Cisco TFTP on error.
  C. Phone firmware must be manually copied to any applicable load servers.
  F. This option does not accommodate falling back to Cisco TFTP on error.
