Explanation

Option D (4) is correct because each BlackBerry Enterprise Server (BES) instance generates 2 BlackBerry Messaging Agents - one to handle inbound and one to handle outbound message traffic with the messaging server. With BES instances in both London and New York, that yields 2 instances × 2 agents each = 4 BMAs total.

Why the distractors fail:

A (1) and B (2) undercount - they'd only be correct if there were a single BES instance (2 agents) or a single agent across the whole environment.
C (3) has no basis in standard BES architecture; no standard formula produces an odd number across two symmetrical sites.
E (5) overcounts - it might tempt candidates who misremember a different agent or service count from BES documentation.

Memory tip: Think "BES always works in pairs" - every BES instance needs 2 agents (one in, one out), so multiply the number of BES sites by 2. Two sites = 4 agents.
