Which two SRV records are needed for a load balanced solution? (Choose two.)

  A. sip_udp.abc.com 60 IN SRV 1 40 5060 cube2.abc.com

  B. sip_udp.abc.com 60 IN SRV 3 60 5060 cube2.abc.com

  C. sip_udp.abc.com 60 IN SRV 60 1 5060 cube1.abc.com

  D. sip_udp.abc.com 60 IN SRV 2 60 5060 cube1.abc.com

  E. sip_udp.abc.com 60 IN SRV 1 60 5060 cube1.abc.com

  Correct Answer: AE

  -Service: The symbolic name of the desired service

  -

  Proto: The transport protocol of the desired service; this is usually either Transmission Control Protocol (TCP) or User Datagram Protocol (UDP)

  -

  Name: The domain name for which this record is valid, it ends in a dot

  -TTL: Standard DNS time to live field

  -Class: Standard DNS class field (this is always IN)

  -

  Priority: The priority of the target host, lower value means more preferred

  -

  Weight: A relative weight for records with the same priority, higher value means more preferred

  -Port: The TCP or UDP port on which the service is to be found

  - Target: The canonical hostname of the machine that provides the service, it ends in a dot

• Question 285:

  When configuring Cisco Unified Communications Manager, which configuration enables phones to automatically register to a Cisco Unified Communications publisher when the connection to the subscriber is lost?

  A. Cisco Unified CM Group

  B. Device Pool

  C. SRST

  D. Route Group

  Correct Answer: A

  SRST is filed under device pool settings : " SRST Reference: This is an optional field. Survivable Remote Site Telephony is a redundancy feature available on Cisco IOS routers that allows Cisco Unified IP phones registered to the Cisco Unified Communications Manager from remote office locations to register to their local router during WAN network failure events. The SRST reference determines where those phones should register during these situations"

• Question 286:

  Endpoint A is attempting to call endpoint B. Endpoint A only supports G.711ulaw with a packetization rate of 20 ms, and endpoint B supports packetization rate of 30 ms for G.711ulaw. Which two media resources are allocated to normalize packetization rates through transrating? (Choose two.)

  A. Hardware MTP on Cisco IOS Software

  B. Software MTP on Cisco Unified Communication Manager

  C. Software MTP on Cisco IOS Software

  D. Software transcoder on Cisco unified Communications manager

  E. Hardware transcoder on Cisco IOS Software

  Correct Answer: AB

  While a transcoder could work, MTP is sufficient and the better answer. CUCM and IOS have MTP resources, but IOS can only handle transrating when using DSPs (which would be configured as a hardware MTP).

• Question 287:
