You are a CCM administrator at Certkiller . Your newly appointed Certkiller trainee wants to know how the runtime information regarding registered devices is propagated from one CCM server to another.
What will your reply be?

A.
Each CCM server establishes an SDL link to all the other CCM servers in the cluster to propagate runtime information.

B.
One server becomes the designated distributor and is responsible for distributing runtime information to all the cluster members.

C.
Each CCM server in the cluster sends IP Multicast messages to the other CCM servers in the cluster reporting current runtime information such as registered devices.

D.
Each CCM server establishes an SDL link to the publisher.
All runtime information from the subscribers is passed up to the publisher, which then replicates the data back to the subscribers.
