Explanation

In a Cisco Unified CallManager (CUCM) 5.0 cluster, the publisher node holds the master read/write database and replicates it outward - subsequent (subscriber) nodes receive that data and maintain read-only copies of the configuration database (D), while still being fully capable of processing IP telephony calls (A) and collecting Call Detail Records (B) for their registered devices.

Option C is the distractor to watch: database replication is the publisher's job, not the subscriber's. Subscribers consume the replicated data; they don't push it to others.

Memory tip: Think of subscribers as workers, not managers - they handle calls (A), log them (B), and read the rulebook (D), but they never write or distribute the rulebook (C). Only the publisher/master does that.
