Which two software components in Cisco Meeting Server deployment supports clustering for resilience only?
C, G
2.7.2 XMPP resiliency
The Cisco Meeting Server supports XMPP resiliency in multi-server deployments. XMPP
resiliency provides fail-over protection for a client being unable to reach a specific XMPP server.
When setup in resilient mode, the XMPP servers within a deployment are loaded with the same
configuration. Each knows the location of the others and they establish links between them.
XMPP resiliency provides fail-over protection for a client being unable to reach a specific XMPP
server. XMPP resiliency can be configured in multi-server deployments where there are three
XMPP servers in the deployment.
2.2 Call Bridge
In a scalable and resilient deployment, Call Bridges can be clustered which allow multiple Call
Bridges to operate as a single entity, and scale beyond the capacity of any single Call Bridge.
Call Bridges in a cluster can be configured to link peer-to-peer, or for calls to route via call
control devices between the clustered Call Bridges.
2.3 Database
In a scalable and resilient deployment, the database can be detached from the Call Bridge and
run as a separate component. It can be on the held on the same server as the Call Bridge or on a
different server. Multiple instances of the database can be clustered together to provide
resiliency in the deployment.
Database clustering works differently to Call Bridge clusters. A database cluster creates what is
essentially an ‘online’ backup of the running database which is maintained as the system runs. It
also provides the ability to move to using the backup in an automated fashion in the event of a
failure being detected.

I think also CG
I believe correct answer is CG according to https://www.cisco.com/c/dam/en/us/td/docs/conferencing/ciscoMeetingServer/Deployment_Guide/Version-2-5/Cisco-Meeting-Server-2-5-Scalable-and-Resilient-Deployment.pdf
