• BBlackBerry MDS Integration Service
• CBlackBerry Monitoring Service

  10% (3)

Explanation

In BlackBerry Enterprise Server (BES), high availability (HA) pooling allows multiple instances of a component to share load and provide failover. The BlackBerry Administration Service (A) supports HA pooling because administrators need uninterrupted access to manage the environment. The BlackBerry MDS Integration Service (B) supports it because it handles push-based application data that must remain available. The BlackBerry Router Service (E) supports it because it manages the critical connection between BES and BlackBerry's infrastructure network, making it a prime candidate for redundancy.

The distractors are wrong because:

• C (Monitoring Service) - It observes and reports on BES health but is not itself a poolable service; it operates as a single oversight instance.
• D (Dispatcher Service) - It routes data internally between BES components but functions as a single-instance core process and is not eligible for HA pooling.

Memory tip: Think "ABE can survive" - the three components that directly serve users or carry live data (Admin, MDS, External Router) get the redundancy treatment, while the internal plumbing (Dispatcher) and the watchdog (Monitoring) do not.
