Abc .com is designing a new MCS 5100.3.0 system and
wants to configure the system in a single-network
deployment. To support the number of users, two SIP
application servers will be used and each one will
be connected to two Layer 2 switches for redundancy.
The customer is concerned about reliability and wants
to ensure that the Loss of a SIP application server
will NOT impact call processing or existing media
flows. Which recommendation should you make to address
the customer's reliability concerns?
A. Add an additional SIP Application server as a standby
B. Configure the MCS 5100 system in a dual-network
C. Configure one of the two SIP Application servers
as a standby server
D. Configure the MCS 5100 system in a dual-network
deployment and add an additional SIP Application server
as a standby server.
A large, international customer with multiple sites
spanning two countries is considering an MCS 5100.3.0
deployment on their existing. EnterpriseIP network.They
are evaluating the possibility of placing the NetworkSignalingCenter(NSC)
at their headquarters, given its high network availability,
site security, and site diversity. They also have
decided to place the SIP application Modules at the
headquarters. What information do you need to collect
from the customer to justify the placement of the
NSC at the headquarters?
A. the planned location of the Database Module
B. the locations of the IP Phone population
C. the number and location of the active Media Application
D. the planned location of the Public Switched Telephone
Network (PSTN) connection
Abc .com has an MCS 5100.3.0 four-server system. To
implement redundancy and increase the capacity of
their system they have decided to upgrade it to an
eight-server system. Currently, the Management and
Accounting Modules are installed on the same server
(S1) in the four-server system. A second server (S2)
HAS BEEN INSTALLED TO UPGRADE THE SYSTEM TO THE eight
servers. How will redundancy be provided for the Management
and accounting Modules in the eight-server system?
A. The Management and Accounting Modules will be active
on both S1 and S2 and will load share the traffic
and provide hot backup.
B. The active Management and Accounting Modules will
be on S1 and the standby Management and Accounting
Modules will be on S2.
C. The active Management and standby Accounting Modules
will be on S1 and the active Accounting and standby
Management Modules will be on S2.
D. The Management Module will be active on S1 and
the Accounting Module will be active on S2. An additional
server will be required to provide redundancy for
Abc .com owns and supports an existing IP-based Enterprisenetwork.
They plan to deploy an MCS 5100.3.0 system as an application
overlay on their existing network. Accounting to the
MCS 5100 logical hierarchy, the third phase of the
design process is the planning for voice, video, collaboration,
and instant Messaging (IM) traffic. Assume that you
have the following traffic information:
1. Planned traffic capacity at each Point-of-Presence
2. Client type mix at each PoP
3. Traffic characterization (average holding time,
Erlangs or Centum Call Seconds [CCS] for each subscriber)
What additional information is required for detailed
traffic characteristic identification?
A. CODEC distribution
B. Public Switched Telephone Network (PSTN) traffic
C. Traffic distribution model between PoPs and the
D. Traffic distribution characteristics from the MCS
5100 PoPs to the PSTN
Abc .com is designing a new MCS5100.3.0 system and
wants to install an H.323 Gatekeeper to interwork
with a Communication Server (CS) 1000 Release 4.0
system. They want to ensure that the ability to communicate
with the CS 1000system is NOT lost should the H323
Gatekeeper fail. What should you recommend to the
customer to address this reliability issue?
A. Configure the SIP Application Module to act as
a Failsafe H.323 Gatekeeper.
B. Configure the H.323 Gatekeeper in the CS 1000 system
as a Secondary Gatekeeper for the MCS 5100 system.
C. Deploy a second H.323 Gatekeeper on a separate
server and define it as the Secondary Gatekeeper
D. Deploy a second H.323 Gatekeeper on a separate
server, define both H.323 Gatekeepers as Primary and
allow them to load share the traffic.
Abc .com plans to install a non-redundant MCS 5100.3.0
system in a dual-network deployment. A RTP Media Portal
will also be installed to protect the integrity of
the private MCS 5100 network, and to provide multimedia
services for sip client within and outside of the
private network. How should the RTP Media Portal be
connected to the network?
A. both Ethernet interfaces are within the private
MCS 5100 network
B. both Ethernet interfaces are within the Enterprise
C. in the boundary between the private and public
D. in the boundary between the private and public
networks as well as in series with a firewall
