NNCDS-Communication Server (CS)1000 Release 4.0
A customer wants to configure the Enterprise Media Gateways (EMG) on their CS 1000 Rls. 4.0
system for survivability. They also need to interpret the network requirements for the system.
Which configuration ensures network survivability?
A. The survivable EMG TLAN IP address must be on the same TLAN subnet as the Call Server.
B. The survivable EMG ELAN IP address must be on the same ELAN subnet as the Call Server.
C. The survivable EMG ELAN IP address must be on a different ELAN subnet than the Call
D. The survivable EMG must be separated from the Call Server by a Layer 3 device networked
with the two Call Servers.
A customer is considering the deployment of the a H.323 Gatekeeper in failsafe mode for a CS
1000 Rls. 4.0 solution. Which statement most accurately describes why you would recommend
A. Communication to the primary and secondary H.323 Gatekeepers will never be lost.
B. The Failsafe H.323 Gatekeeper within a gatekeeper zone takes over gatekeeper responsibilities
for all of its peers within the zone.
C. If communication is lost with the primary H.323 Gatekeeper, the secondary gatekeeper will
become the primary and run in failsafe mode.
D. If communication is lost to both gatekeepers, the H.323 Gateway running the failsafe
gatekeeper services will continue to route calls in a best-effort fashion until communication is
A company is planning the deployment of a new CS 1000 Rls. 4.0 system and requires ultra-high
reliability. How would campus redundancy meet their needs?
A. It provides an optionally redundant Signaling Server.
B. It moves the Gatekeeper to a standalone Signaling Server.
C. It duplicates the entire processing core of a CS 1000E fault resilient system.
D. It provisions an Enterprise Media Gateway 1000E as a CS 1000E Call Server.
