QUESTION 11

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.

configuration of virtual-to-physical network interface mapping

C.

step-by-step procedures for hardware BIOS, firmware, drivers, and RAID setup

< /td>

E.

configuration settings and patch recommendations for VMware software

 

Correct Answer: D

Explanation:

What does a TRC definition include?

Definition of server model and local components (CPU, RAM, adapters, local storage) at the orderable part number level.

Required RAID configuration (e.g. RAID5, RAID10, etc.) – including battery backup cache or SuperCap – when the TRC uses DAS storage

Guidance on hardware installation and basic setup (e.g. click here). Design, installation and configuration of external hardware is not included in TRC definition, such as:

Configuration settings, patch recommendations or step by step procedures for VMware software are not included in TRC definition.

Infrastructure solutions such as Vblock from Virtual Computing Environment may also be leveraged for configuration details not included in the TRC definition.

QUESTION 14

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.

 

Correct Answer: CF

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

 

 

QUESTION 15

Refer to the exhibit. Assuming that the administrator has never performed any manual custom uploads, which two file types can be found when you choose Software Upgrades, followed by TFTP File Management on the Cisco Unified Operating System Administration web page for Cisco Unified Communications Manager? (Choose two.)

 

clip_image002

 

A.

IP phone configuration files

B.

announcement audio files

C.

ringer files

D.

IP phone license files

E.

sample music-on-hold audio files

F.

softkey template files

 

Correct Answer: BC

Explanation:

The two file types that we get are Announcement Audio Files and Ringer Files.

 

 

QUESTION 16

In a Cisco EnergyWise domain, which two terms describe a Cisco IP phone? (Choose two.)

 

A.

endpoint

B.

domain member

C.

child domain member

D.

EnergyWise agent

E.

Cisco power distribution unit

 

Correct Answer: AC

Explanation:

QUESTION 17

Which protocol does the Cisco Prime LAN Management Solution application use to communicate with Cisco EnergyWise domain members?

 

A.

UDP broadcast

B.

Cisco Discovery Protocol

C.

UDP unicast

D.

TCP

E.

multicast

 

Correct Answer: D

Explanation:

Cisco Prime LMS 4.1 uses TCP port 43440.

 

 

QUESTION 18

Which definition is included in a Cisco UC on UCS TRC?

 

A.

required RAID configuration, when the TRC uses direct-attached storage

B.

configuration of virtual-to-physical network interface mapping

C.

step-by-step procedures for hardware BIOS, firmware, drivers, and RAID setup

D.

configuration settings and patch recommendations for VMware software

E.

server model and local components (CPU, RAM, adapters, local storage) by name only; part numbers are not included because they change over time

 

Correct Answer: A

Explanation:

Definition of server model and local com
ponents (CPU, RAM, adapters, local storage) at the orderable part number level.

Required RAID configuration (e.g. RAID5, RAID10, etc.) – including battery backup cache or SuperCap – when the TRC uses DAS storage

Guidance on hardware installation and basic setup.

Design, installation and configuration of external hardware is not included in TRC definition, such as:

Configuration settings, patch recommendations or step by step procedures for VMware software are not included in TRC definition.

Infrastructure solutions such as Vblock from Virtual Computing Environment may also be leveraged for configuration details not included in the TRC definition.

 

 

 

 

 

 

 

 

 

 

 

QUESTION 19

Refer to the exhibit. During a QSIG tunneling over SIP call establishment, which two types of SIP messages can the OGW use to tunnel a waiting QSIG message? (Choose two.)

 

clip_image003

 

A.

SIP re-INVITE

B.

SIP NOTIFY

C.

SIP INFO

D.

SIP OPTIONS

E.

SIP UPDATE

F.

SIP REFER

 

Correct Answer: AE

Explanation:

The TGW sends and the OGW receives a 200 OK response–the OGW sends an ACK message to the TGW and all successive messages during the session are encapsulated into the body of SIP INFO request messages. There are two exceptions:

When a SIP connection requires an extended handshake process, renegotiation, or an update, the gateway may encapsulate a waiting QSIG message into a SIP re-INVITE or SIP UPDATE message during QSIG call establishment.

When the session is terminated, gateways send a SIP BYE message. If the session is terminated by notice of a QSIG RELEASE COMPLETE message, that message can be encapsulated into the SIP BYE message.
