Which log file should an administrator review to ensure consistent connectivity stability between primary and remote disaster recovery sites?

The Cerebro service manages protection domains, remote site replication, and snapshot shipping. All connectivity checks, tunnel heartbeats, retries, and errors between primary and DR clusters are written to cerebro.INFO, making it the authoritative log to verify link stability.

A. mantle.out – Host management operations; no replication details.
B. genesis.out – Cluster initialization and configuration, not ongoing DR connectivity.
C. prismmonitor.INFO – Monitors Prism services; excludes replication traffic.
