Explanation:
Choosing the Right Distribution Method
Which of the three different image-distribution methods discussed so far is the best for a
customer deployment? Each method has advantages and disadvantages, and they are
summarized in Table 1.
Table 1. Summary of Distribution Models
Peer Firmware Sharing
Load Server
Traditional TFTP
Advantages
• 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
• Has same download time as LAN image distribution
• Distributes TFTP load over multiple TFTP servers
• Proven distribution
• Default behavior
Disadvantages
• Must be enabled on each phone
• Hierarchy is formed for each phone model
• Hierarchy is limited to subnet
• IP must be set on each phone
• Administrator must manually file copy to load server
• No failback to TFTP on error
• More prone to user error
• High-bandwidth requirements
• Multiple requests for same file
• High CPU usage on TFTP server
Question No : 3 – (Topic 1) Which statement describes a disadvantage of using the Cisco TFTP service to serve IP
phone load files?
A. The Cisco TFTP services can run on only one Cisco Unified Communications Manager
server in a cluster.
B. Because TFTP operates on top of UDP, there is a high risk of corrupted load file delivery
at the completion of the TFTP process due to undetected data loss in the network.
C. If a response is not received in the timeout period, the TFTP server will not resend the
data packet.
D. Packet loss can significantly increase the TFTP session completion time.
E. Because TFTP operates with an adaptive timeout period, the time to complete the file
transfer is unpredictable.
400-051 pdf Answer: D
Explanation:
Voice traffic cannot recapture lost packets. Rather than retransmitting a lost network
connection, the phone resets and attempts to reconnect its network connection.
Reference:
Question No : 4 – (Topic 1) Which capability is supported by Cisco Discovery Protocol but not by LLDP-MED?
A. LAN speed and duplex discovery
B. Network policy discovery
C. Location identification discovery
D. Power discovery
E. Trust extension
Answer: E
Explanation:
Cisco Discovery Protocol provides an additional capability not found in LLDP-MED that
allows the switch to extend trust to the phone. In this case, the phone is now trusted to
mark the packets received on the PC port accordingly. This feature can be used to off-load
the switch because now it does not need to police the information being received from the
phone.
Question No : 5 – (Topic 1) 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.

Which statement about the Cisco UC on UCS TRC and the third-party server specs-based
virtualization support model is true?
A. Both the UC on UCS TRC and the third-party servers spec-based support models have
rule-based approaches.
B. The UC on UCS TRC support model has a rule-based approach and the third-party
servers spec-based support model has a configuration-based approach.
C. The UC on UCS TRC support model requires a high level of virtualization experience
while the third-party server spec-based support model requires a low to medium level
virtualization experience.
D. VMware vCenter is mandatory for the UC on UCS TRC support model but it is optional
for the third-party server spec-based support model.
E. VMware vCenter is optional for the UC on UCS TRC support model but it is mandatory
for the third-party server spec-based support model.
Answer: E
Explanation:
VMware vCenter is
optional when deploying on UC on UCS Tested Reference Configuration hardware
mandatory when deploying on UC on UCS Specs-based and Third-party Server
Specs-based hardware.
vCenter Statistics Level 4 logging is mandatory so that Cisco TAC is able to
provide effective support.
Click here for how to configure VMware vCenter to capture these logs. If not
configured by default, Cisco TAC may request enabling these settings in order to
provide effective support.
Also note that enablement of specific VMware vSphere management features may
require vCenter and/or a higher feature Edition of vSphere ESXi.
Cisco Collaboration does not require its own dedicated vCenter.
Note that when VMware vCenter is not required and is not used, then VMware
vSphere ESXi’s default management interface is its free/included VMware vSphere
Client (formerly branded VI Client).

trunk to trunk connections. Thus, 8 subscribers.
Question No : 11 – (Topic 1)
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.
400-051 pdf 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
Question No : 12 – (Topic 1)
Which two mechanisms does Cisco EnergyWise use for neighbor discovery? (Choose
two.)
A. multicast
B. LLDP-MED
C. UDP broadcast
D. Cisco Discovery Protocol
E. TCP
Answer: C,D
Explanation:
Cisco EnergyWise Neighbor Discovery Process
The Cisco EnergyWise neighbor discovery process is the mechanism by which domain
members discover each other and populate their Cisco EnergyWise neighbor tables. Cisco
EnergyWise queries can subsequently be distributed to all domain members using the
neighbor relationships to monitor and control the power usage of devices within a domain.
Cisco EnergyWise domain members automatically discover their neighbors through one of
two mechanisms:
Cisco EnergyWise UDP broadcast packet
Cisco EnergyWise CDP packets
UDP broadcast packets are automatically sent out switch ports which support Cisco
EnergyWise, regardless of whether the interfaces are configured with the no energywise
interface-level command. CDP packets are sent when CDP is configured for the switch
ports.

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
400-051 pdf Answer: A
Explanation:
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.
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 No : 14 – (Topic 1) Which capability is support by LLDP-MED but not by Cisco Discovery Protocol?
A. LAN speed discovery
B. network policy discovery
C. location identification discovery
D. power discovery
E. trust extension
400-051 dumps Answer: A
Explanation:
LLDP-MED supports both LAN speed and duplex discovery. Cisco Discovery Protocol
supports duplex discovery only, but this limited support is not seen as a problem because if
there is a speed mismatch, LLDP-MED and Cisco Discovery Protocol cannot be
exchanged and thus cannot be used to detect the mismatch.
