The correct answer is C. 5. Option C (5) is correct because the scenario establishes that TeamOn currently operates with 3 regional BES instances, and a 50% increase yields 3 × 1.5 = 4.5 - which must be rounded up to the nearest whole server, giving a minimum of 5 BES instances.

Explanation

Option C (5) is correct because the scenario establishes that TeamOn currently operates with 3 regional BES instances, and a 50% increase yields 3 × 1.5 = 4.5 - which must be rounded up to the nearest whole server, giving a minimum of 5 BES instances.

Why the distractors fail:

A (3) reflects the current count before growth - it ignores the 50% expansion entirely.
B (4) is the trap answer: it incorrectly rounds 4.5 down, but you cannot host a fraction of a server, so you must always round up.
D (6) and E (7) exceed the minimum requirement; the question asks for the minimum needed, not a comfortable buffer.

Memory tip: For BES capacity questions, remember "fractional server = full server" - always apply ceiling math (round up), never floor. A quick check: current × growth factor → round up gives your minimum.
