Explanation

In BlackBerry Enterprise Server 5.0, database mirroring is supported specifically for the Configuration database (A) and the MDS Integration Services database (B) because these two stores contain the most critical operational data - server configuration, policies, and middleware integration state - making high availability essential for enterprise deployments.

The distractors are wrong because the BlackBerry Monitoring database (C) holds performance/logging data that is non-critical for failover, the BlackBerry Dispatcher (D) is a service component, not a database, and the BlackBerry User Administration database (E) does not appear as a separately mirroring-supported database in the BES 5.0 architecture.

Memory tip: Think "Core Mission-critical" - Configuration and MDS are the two you mirror, because losing either would break server operation or third-party integration. The others are either logs, services, or unsupported stores.
