Explanation

BlackBerry Attachment Service is specifically designed to support multiple instances in a failover pool, allowing another instance to take over attachment processing if one server fails - making it the only option here architected for high availability redundancy.

The distractors are wrong for these reasons:

• A (Alert Service) handles push notifications and is a singleton component not designed for pool-based redundancy.
• B (Policy Service) distributes IT policies to devices and operates as a single authoritative service per BES environment.
• C (Monitoring Service) is an observability/health-check component - putting the monitor itself in a failover pool would be circular and is not supported.
• E (Database Consistency Service) is a maintenance utility that runs checks on the BES database; it is not a runtime service that requires or supports pool failover.

Memory tip: Think "Attachments = load" - attachment processing is the most resource-intensive, stateless task in BES (just converting files), which makes it the natural candidate for horizontal scaling and failover pooling. If a service handles content transformation rather than state or policy, it's the one you can safely duplicate.
