Answer: C


Q2. Which statement about Cisco EnergyWise domain member neighbor formation is true?

A. Cisco EnergyWise supports static neighbors, but the neighbor relationship is only possible if a noncontiguous domain member and a contiguous domain member have a static neighbor entry pointing to each other.

B. Cisco EnergyWise static neighbors can be formed even if domain members are not physically contiguous.

C. Static neighbors can be manually defined on Cisco EnergyWise domain members, but TCP protocols must be used.

D. Static neighbors can be manually defined on Cisco EnergyWise domain members, but they have a lower priority compared to the autodiscovered members.

E. Static neighbors can be manually defined on Cisco EnergyWise domain members and the TCP or UDP protocol can be used.

Answer: B

Q3. Which two statements about the Peer Firmware Sharing option for lP 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.

Answer: C, F

Explanation:

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


Q4. Refer to the exhibit.

Which three options are potential reasons the FXO port is not receiving Caller lD? (Choose three.)

A. "Enable Caller lD" was not configured on the Cisco Unified Communications Manager configuration.

B. The FXO port was configured to "loop-start" instead of "ground-start".

C. The Timing Guard-out parameter is incorrectly set to 1500 ms.

D. "Connection polar opx immediate" was used and does support caller lD.

E. Gateway with lOS 12.4(24T) was used and does not support this feature.

F. The NTFY message contains a Hung Up parameter.

Answer: A, C, E


Q5. A voice engineer is trying to configure CUCM to satisfy the following customer codec requirements.

- All lP phones should use audio codec at less than 10K bandwidth and maintain voice quality

Q6. Which two compression formats for high-definition video have technical content that is identical to H.264? (Choose two.)

A. MPEG-4 Part 10

B. MPEG-4 Part 14

C. MPEG-2 Part 7

D. AVC

E. VC3

F. VP8

Answer: A, D

Explanation:

MPEG-4 Part 10, also known as MPEG-4 AVC (Advanced Video Coding), is actually defined in an identical pair of standards maintained by different organizations, together known as the Joint Video Team (JVT). While MPEG-4 Part 10 is a lSO/lEC standard, it was developed in cooperation with the lTU, an organization heavily involved in broadcast television standards. Since the lTU designation for the standard is H.264, you may see MPEG-4 Part 10 video referred to as either AVC or H.264. Both are valid, and refer to the same standard.
