QUESTION 1
Company ABC is planning to migrate from MCS-hosted Cisco Unified Communications Manager
applications to Cisco UC on UCS B-Series servers. Which statement about installation media
support is true for this migration?

A. The install log can be written to a USB flash drive that is attached to the UCS server.
B. The answer file that is generated by the Answer File Generator (platformConfig.xml) can be
read from a USB flash drive to perform an unattended installation on the UCS server.
C. The Cisco Music on Hold USB audio sound card can be mapped to a virtual USB port on a
VMware virtual machine on the UCS server.
D. The answer file that is generated by the Answer File Generator (platformConfig.xml) can be
read from an FLP image that is mounted in a virtual floppy drive.
E. The Cisco Music on Hold USB audio sound card can be mapped to a virtual serial port on a
VMware virtual machine on the UCS server.

Answer: D

Explanation:
Using the AFG will allow you to get this license mac before even touching the server. It is provided
after filling in the main form of the AFG but it can also be found by looking at the last few lines of
your platformconfig.xml file.
Once you have the xml files, you will need to map those to the floppy drive of the VM (no usb
support on the VM OVA). There are many ways to do this. I simply use a freeware virtual floppy
app that I drop the platformconfig.xml file on and then copy the*.flp image out to the datastore. I’ll
end up with a directory on my datastore called AFG that has the host named *.flp images that I will
use during install. It also serves as archival of these files in the event the server needs to be reimaged.
This is important because the license mac will change if every parameteris not entered
exactly as it was prior. If the license mac changes, you will have to go through the process of
requesting new license files to be generated.

QUESTION 2
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 rulebased
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

QUESTION 3
Which definition is included in a Cisco UC on UCS TRC?

A. storage arrays such as those from EMC or NetApp, if applicable
B. configuration of virtual-to-physical network interface mapping
C. step-by-step procedures for hardware BIOS, firmware, drivers, and RAID setup
D. server model and local components (CPU, RAM, adapters, local storage) at the part number
level
E. configuration settings and patch recommendations for VMware software

QUESTION 4
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 5
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.

QUESTION 6
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

Answer: D

Explanation:
Cisco Prime LMS 4.1 uses TCP port 43440.
