NO.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 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.
B. 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.

Answer: A

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 re-imaged. This is important because the license mac will change if every parameter is
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.

NO.2 Which statement describes how the digit zero is handled in the predefined restriction tables in
Cisco Unity Connection?
A. Zero is listed in the User-Defined and Automatically Added Alternate Extensions Restriction table.
B. Zero is listed in the Default System Transfer Restriction table.
C. Zero is listed in the Default Transfer Restriction table.
D. Zero is listed in the Default Out-Dial Restriction table.
E. Zero is not listed in any default restriction table configuration.
Answer: E

400-051試験資料   400-051技術者   
Explanation:
When user dials "0", by default Unity Connection treats it as an operator call and does not block "0"
by any restriction table configuration. Only the operator can modify transfer extension associated
with operator call.

A. alternate file server
B. NFS server
C. FTP server
D. local disk
E. load server
F. internal caches
Answer: A,D,F

NO.4 On a Cisco Unified Communications Manager SIP trunk with a single remote device and
OPTIONS ping feature enabled, which response from the SIP remote peer causes the trunk to be
marked as "Out of Service"?
A. 505 Version Not Supported
B. 401 Unauthorized
C. 408 Request Timeout
D. 406 Not Acceptable
E. 500 Server Internal Error
Answer: C

400-051模擬対策   
Explanation:
408 Request Timeout
Couldn't find the user in time. The server could not produce a response within a suitable amount of
time, for example, if it could not determine the location of the user in time. The client MAY repeat
the request without modifications at any later time

NO.5 Refer to the exhibit.
How many SIP signaling dialog(s) took place in this SIP message exchange between two SIP user
agents?
A. 4
B. 3
C. 1
D. 2
E. 5
F. 6
Answer: C

Explanation:
During the establishment, maintenance and termination of a SIP session, signaling messages are
exchanged between the two SIP endpoints. There are two different kinds of signaling "conversations"
that those messages take part in: transactions and dialogs. A transaction is a SIP message exchange
between two user-agents that starts with a request and ends with its final response (it can also
contain zero or more provisional responses in between). For example, during the termination of a SIP
session, one user releases the call by sending a BYE request and the other party replies back with a
200 OK response. This message exchange is called a transaction. But what happens in the case of the
INVITE request? The establishment of a SIP session starts basically with an INVITE request and is
considered as completed upon the receipt of the ACK. In this case, the transaction starts with the
INVITE request and ends with the 200 OK, so the ACK is not part of the transaction. The ACK can be
considered as a transaction on its own. However, when the final response to an INVITE is not a 2xx
response, then the ACK is considered as part of the transaction. A dialog is a complete exchange of
SIP messages between two user-agents. That means that transactions are actually parts of a dialog.
For example, in the case of a SIP session establishment, a dialog starts with the INVITE-200 OK
transaction, continues with the ACK and ends with the BYE-200 OK transaction. The picture below
depicts the dialog and transactions that take place during the establishment of a SIP session: Note:
There can also be subsequent requests that belong to the same dialog, such as a BYE or a re-INVITE
message. As out-of-dialog requests are considered messages such as an initial INVITE request for a
new session or an OPTIONS message for checking capabilities. There are different SIP
headers/parameters that identify the dialogs and transactions, and they will be analyzed in later
posts.

NO.6 What does a period accomplish when it is used in a SIP Dial Rule pattern that is associated
with a Cisco 9971 IP Phone that is registered to Cisco Unified Communications Manager?
A. It matches any single digit from 0 to 9, or the asterisk (*) or pound (#) symbols.
B. It matches any single digit from 0 to 9.
C. It matches one or more digits from 0 to 9.
D. It is a delimiter and has no significant dialing impact.
E. It matches one or more digits from 0 to 9, or the asterisk (*) or pound (#) symbols.
Answer: A

400-051ガイド   
Explanation:
Asterisk (*) matches one or more characters. The * gets processed as a wildcard character. You can
override this by preceding the * with a backward slash (\) escape sequence, which results in the
sequence \*. The phone automatically strips the \, so it does not appear in the outgoing dial string.
When * is received as a dial digit, it gets matched by the wildcard characters * and period (.).

NO.7 Which two statements describe security services that are provided by the Phone Proxy function
on a Cisco ASA appliance? (Choose two.)
A. It supports IP phones that send phone proxy traffic through a VPN tunnel.
B. It proxies phone media so that internal phones are not directly exposed to the Internet.
C. It provides interworking to ensure that the external IP phone traffic is encrypted, as long as the
Cisco Unified Communications Manager cluster runs in secure mode.
D. It provides a proxy of phone signaling, with optional use of NAT, to hide the Cisco Unified
Communications Manager IP address from the public Internet.
E. It is supported only on phones that use SCCP.
F. It is supported on an adaptive security appliance that runs in transparent mode.
Answer: B,D

400-051受験対策   
Explanation:
TLS Proxy is typically deployed in front of Cisco Unified Communications Manager and other unified
communications application servers that utilize media encryption. TLS Proxy is not designed to
provide remote-access encryption services for remote phones or client endpoints. Other solutions
such as Cisco ASA Phone Proxy or IP Security/Secure Sockets Layer (IPsec/SSL) VPN services are more
appropriate. TLS Proxy is not designed to provide a secure campus soft phone solution where the
requirement is to provide secure data to phone VLAN traversal or for proxying connections to Cisco
Unified Communications Manager.

NO.8 Which two steps must be taken when configuring EMCC? (Choose two.)
A. An SFTP server that all clusters share must be set up.
B. A device pool for EMCC phones must be configured.
C. Certificates from all remote clusters must be imported into each cluster.
D. Cross-cluster Enhanced Location CAC must be configured.
E. Define MLPP domains.
F. End users must be configured to only exist in their home cluster.
Answer: A,C
