Answers, Braindumps (920-452)
to www.exams.ws and www.4exam.com But there’s
no need to have it from both of them, questions from
only one are sufficient I think.
Abc .com has a network that contains several Communication
Server (CS) 1000 Rls 4.0 systems. They are networked
together via Virtual Trunks. The customer has limited
bandwidth on the WAN links between sites and has an
Optimized WAN link to carry Voice calls that use G.729
A. Which configuration setup will ensure that G.729
is always used on a virtual trunk call between sites?
A. No extra configuration is needed. Virtual Trunk
calls always use G.729A CODEC.
B. Configure the virtual route to be in same zone
as voice gateway channels and IP sets ? verify that
the customer has G.729A as part of CODEC profile ?
verify all zones at the site are configured with best
quality for intrazone calls and best bandwidth for
C. Virtual route is configured to be in different
zone than the voice gateway channels and IP sets ?
verify the customer has G.729A as part of CODEC profile
? ensure all zones at the site are configured with
best quality for intrazone calls and best quality
for interzone calls
D. The virtual route is configured to be in a different
zone than voice gateway channels and IP Sets for each
system ? verify the customer has G.729A as part of
CODEC profile ? ensure all zones at the site are configured
with best quality for intrazone calls and best bandwidth
for interzone calls
Abc .com has a Communication Server (CS) 1000 Rls.
4.0 that they want to network with two other sites
using the corporate WAN. Why must zones be configured
with Element Manager before the Virtual Routes? (Choose
A. Zones determine NCOS privileges on a given trunk.
B. Zones govern trunk groupings for TGAR assignment.
C. Zones help determine Best Bandwidth CODEC per virtual
D. Zones manipulate CODEC selections and assigns bandwidth
to a route.
E. Zones provide call blocking based on Bandwidth
defined for inter- and intra-zone calls.
Abc .com has installed two Communication Server (CS)
1000M Rls. 4.0 systems networked over the corporate
WAN. Some of the system management functions of the
CS 1000M can be performed by the Command Line Interface
(CLI) as well as Element Manager. Which is a false
statement regarding the use of Element Manager (EM)
over the CLI?
A. EM provides for drop down menus for prompt choices.
B. EM provides full text descriptions of parameters
C. EM allows the programmer to use the LD commands
as well as using menus.
D. EM increases speed and efficiency be organizing
parameters to logical groups.
Abc .com has just installed a Communication Server
(CS) 1000M system. The CS 1000M is networked via the
corporate WAN with several offices around the country.
BARS is configured correctly for all telephones to
use this route and the Virtual Trunks show IDLE. Traffic
studies have shown that the majority of calls to remote
locations are going out via the PSTN route instead
of the virtual route. What in the configuration could
cause this situation?
A. CODEC is not assigned to the Virtual Trunk Route
B. Bandwidth is incorrectly defined in the Zone Basic
C. CODEC not defined for the zone in the Zone Basic
D. Bandwidth is not defined for the Virtual Trunk
Route and member trunks
Abc .com is installing a Communication Server (CS)
1000M-SG Rls. 4.0 at their Main Office (MO). They
have a 10-member network using the corporate WAN and
a Primary Gatekeeper. They want to use an Alternate
Gatekeeper for redundancy. When are the Alternate
Gatekeepers programmed? (Choose two.)
A. during software installation and initial setup
of the Signaling Server
B. in Overlay LD 17 (Configuration) under the ADAN
as an ELAN IP address
C. in Overlay LD 117 (Configuration2) as an Embedded
LAN (ELAN) IP address
D. in Element Manager under the Signaling Server setting
after the software has been installed
A company has a multi-site Communication Server (CS)
1000M-Chassis Rls. 4.0 system. If one of the Media
Gateways goes into Survival Mode, they want Manual
Control to restore the Media Gateway into Normal Mode.
In Overlay LD 117, which command should you use to
achieve this configuration?
A. Chg Surv <port> No
B. Chg Surv <port> Yes
C. Chg Autosb <port> No
D. Chg Autosb <port> yes
E. Chg Swoto <port> <value>
A company has a two-site Communication Server (CS)
1000 Rls. 4.0 system (site A and B) providing IP-PBX
services. Both systems are networked via a managed
IP backbone. One system is a CS 1000 Rls. 3.0 Main
Office (MO) and the other is a Media Gateway 1000
Rls. 4.0 branch office (BO). You configure the networked
systems to enable the following: ? Users at the MO
to call BO workstations by dialing 49xxx. ? Users
at the BO to call MO workstations by dialing 2xxx.
Which initial configuration task should you perform
using Element Manager (EM)?
A. Configure an LSC of 2 and a DSC of 49 in the MO.
B. Configure a DSC of 2 in the MO and configure VNR
in the BO.
C. Configure a DSC of 49 in the MO and configure Vacant
Number Routing (VNR) in the BO.
D. Configure a Local Steering Code (LSC) of 49 and
a Distant Steering Code (DSC) of 2 in the BO.
Abc .com has installed a Communication Server (CS)
1000M Rls 4.0 system. Currently all 800 IP telephones
at the site are registered to a single Signaling Server
. This site has three installed media cards. What
component(s) should be added at the site to ensure
full redundancy for IP telephones?
A. an additional Signaling Server must be installed
and set as Failsafe
B. an additional Signaling Server must be installed
and programmed as Follower
C. an additional Signaling Server must be installed
and programmed as Alternate
D. two additional media cards to ensure that all 800
IP telephones can register to media cards if the Leader
Signaling Server fails
A company plans to have a Communication Server (CS)
1000 Rls. 4.0 Main Office (MO) site with one Media
Gateway 1000B branch office (BO) site. The BO and
MO will be connected via virtual trunks. Users at
both sites will use Coordinated Dialing Plans (CDPs)
to dial between the sites. They want long distance
and CDP calls originating from the BO to route to
the MO. All long distance calls will be tagged as
international calls originating from the BO. They
have no plans to expand the BO in the future. What
is the most efficient way of routing calls from the
A. In the Gatekeeper, select the BO as the tandem
endpoint for the MO.
B. In the Gatekeeper, select the MO as the tandem
endpoint for the MO.
C. In the Gatekeeper, select the MO as the default
route for CDP and international calls. All NPA ranges
will need to be defined under the MO.
D. In the Gatekeeper, all Numbering Plan Areas (NPAs),
international numbers, and CDP steering codes should
be defined under the MO.
A company has two Communication Server (CS) 1000 Rls.
4.0 systems networked together with the following
* 800 IP Phone 2002 telephones at site A

at site B.
Network Virtual Office is configured to enable IP
telephone users to use their customized settings (i.e.,
autodials, key layout, etc.) on every IP telephone
in the CS network. They want to use the Virtual Office
Automatic Logout (VO_ALO) feature to log out all IP
telephone users from their IP telephones automatically.

you perform using the Command Line Interface (CLI)?
A. Access Overlay LD 15, then enable VOLA.
B. Access Overlay LD 15, then enable VO_ALO.
C. Access Overlay LD 11, then enable VO_ALO for each
Terminal Number (TN).
D. Access Overlay LD 11, then enable Virtual Office
Login Allowed (VOLA) for each TN.
