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.

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.

How many SIP

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.

causes the trunk to be
marked as "Out of Service"?
A. 401

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
