QUESTION 11  (Topic 1)

 

In a Cisco Unified Communications Manager 8.0 cluster, how is database replication accomplished for run-time data?

 

A.

Replication is through a master database from publisher to all active subscribers.

B.

Replication is a mesh from subscriber to subscriber and subscriber to publisher.

C.

Replication is a hybrid using both a hierarchical and mesh process.

D.

Replication is a push from subscriber to publisher.

 

Answer: B

Explanation: The database replicates nearly all information in astar topology (one publisher, many subscribers). However, Cisco Unified Communications Manager nodes also use a second communication method to replicate run-time data in a mesh topology (every node updates every other node)

. This type ofcommunication is used for dynamic

 

 

 

information that changes more frequently than database changes. The primary use of this replication is

to communicate newly registered phones, gateways, and digital signal processor (DSP) resources, so that optimum routing of calls between members of the cluster and the associated gateways occurs.

 

 

QUESTION 12  (Topic 1)

 

What are the three characteristics that govern the type of Cisco Unified Communications Manager deployment model? (Choose three.)

 

A.

number of applications

B.

size

C.

type of applications

D.

network characteristics

E.

services provided by the PSTN carrier

F.

geographical distribution

 

Answer: BDF

Explanation:Selection ofthe type ofdeployment model isbased onseveral factors, including tlie following:

  SizE. Number of IPphones. Cisco Unified Communications Manager servers, and other resources, such

asgateways ormedia resources (conference bridges, music onhold [MOH] servers, and so on)  Geographical distribution: Number and location of sites  Network characteristics: Bandwidth anddelay of network links, andtype of traffic that is carried over ttie network

 

 

QUESTION 13  (Topic 1)

 

What is one of the features of deploying Cisco Unified Communications Manager servers in a 1:1 redundancy design?

 

A.

When the primary servers approach 100% utilization, the backup servers can take over a portion of the load

B.

If a single primary server fails, multiple servers can distribute the load generated by users reregistering from the failed server.

C.

If multiple servers fail concurrently, the resulting load generated by users reregistering does not overwhelm the dedicated backup servers due to 1:1 redundancy.

D.

Recovery happens faster when the load generated by the users from a failed server is spread over more than one backup server
