Explanation

Option A (1) is correct because BlackBerry Enterprise Server (BES) high availability uses a simple active/standby pairing: one primary BES and exactly one standby instance. The standby mirrors the primary and takes over automatically if the primary fails - BES was never designed to support a pool of multiple standbys.

Options B–E are wrong because BES high availability is strictly a 1:1 relationship. Having 2, 3, 4, or 5 standbys is not a supported configuration; BES does not implement multi-standby clustering or N+1 redundancy beyond a single failover node.

Memory tip: Think "one backup, one job." BES high availability = one primary + one standby - just like a spare tire: you carry exactly one, not a trunk full of them.
