NO.1 Which statement describes the Maximum Serving Count service parameter of the Cisco TFTP
service on Cisco Unified Communications Manager?
A. It specifies the maximum number of files in the TFTP server disk storage.
B. It specifies the maximum number of TFTP client requests to accept and to serve files at a given
time.
C. It specifies the maximum file support by the Cisco TFTP service.
D. It specifies the maximum file counts, in cache as well as in disk, that are supported by the Cisco
TFTP service.
E. It specifies the maximum number of TFTP client requests to accept and to serve files in a
120minute window.
Answer: B
Cisco Actual Test 400-051 dumps 400-051 400-051 Training onlineExplanation:
This parameter specifies the maximum number of client requests to accept and to serve files at a
time. Specify a low value if you are serving files over a low bandwidth connection. You can set it to a
higher number if you are serving small files over a large bandwidth connection and when CPU
resources are available, such as when no other services run on the TFTP server. Use the default value
if the TFTP service is run along with other Cisco CallManager services on the same server. Use the
following suggested values for a dedicated TFTP server: 1500 for a single-processor system and 3000
for a dual-processor system. If the dual-processor system is running Windows 2000 Advanced Server,
the serving count can be up to 5000. This is a required field.
NO.2 Which two statements describe security services that are provided by the Phone Proxy function
on a Cisco ASA appliance? (Choose two.)
A. It is supported only on phones that use SCCP.
B. It is supported on an adaptive security appliance that runs in transparent mode.
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 proxies phone media so that internal phones are not directly exposed to the Internet.
F. It supports IP phones that send phone proxy traffic through a VPN tunnel.
Answer: D,E

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.3 What is the minimum number of H.225 messages required to establish an H.323 call with
bidirectional media?
A. 1
B. 2
C. 3
D. 4
E. 5
Answer: B
Cisco Test Questions 400-051 exam simulations 400-051 400-051
Explanation:
A typical H.245 exchange looks similar to below figure After this exchange of messages, the two
endpoints (EP) in this figure would be transmitting audio in each direction. The number of message
exchanges is numerous, each has an important purpose, but nonetheless takes time. For this reason,
H.323 version 2 (published in 1998) introduced a concept called Fast Connect, which enables a device
to establish bi-directional media flows as part of the H.225.0 call establishment procedures. With Fast
Connect, it is possible to establish a call with bi-directional media flowing with no more than two
messages, like in figure 3. Fast Connect is widely supported in the industry. Even so, most devices still
implement the complete H.245 exchange as shown above and perform that message exchange in
parallel to other activities, so there is no noticeable delay to the calling or called party.
NO.4 Which two rules apply to MMOH in SRST? (Choose two.)
A. A maximum of three MOH groups are allowed.
B. Cisco Unified SRST voice gateway allows you to associate phones with different MOH groups on
the basis of their IP address to receive different MOH media streams.
C. A maximum of five media streams are allowed.
D. Cisco Unified SRST voice gateway allows you to associate phones with different MOH groups on
the basis of their MAC address to receive different MOH media streams.
E. Cisco Unified SRST voice gateway allows you to associate phones with different MOH groups on the
basis of their extension numbers to receive different MOH media streams.

users defined in Cisco Unity Connection because the mentioned three greetings are defined for
externals users.
NO.6 Refer to the exhibit.
How many SIP signaling dialog(s) took place in this SIP message exchange between two SIP user
agents?
A. 1
B. 2
C. 3
D. 4
E. 5
F. 6
Answer: A
Cisco 400-051 test answers 400-051 400-051 Practice Exam 400-051 400-051 Bootcamp
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.7 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. 401 Unauthorized
B. 505 Version Not Supported
C. 406 Not Acceptable
D. 408 Request Timeout
E. 500 Server Internal Error
Answer: D
Cisco 400-051 certification training 400-051 Exam DumpsExplanation:
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
