To allow for a growth of 350 BlackBerry device users in Hong Kong, what is the minimum number of BlackBerry Enterprise Server instances required in the international offices? (Choose one)

Question

Options

• AOne in Hong Kong, one in Texas, one in Australia
• BTwo in Hong Kong, one in Texas, one in Australia
• CTwo in Hong Kong, one in Texas
• DTwo in Hong Kong, two in Texas, one in Australia

• A
  72% (21)
• B
  3% (1)
• C
  14% (4)
• D
  10% (3)

Explanation

Option A is correct because a single BlackBerry Enterprise Server (BES) instance supports up to 2,000 users, meaning 350 users in Hong Kong requires only one BES instance there - one server each in Hong Kong, Texas, and Australia satisfies the minimum requirement without over-provisioning.

Options B and D are wrong because they assign two BES instances to Hong Kong, which is unnecessary since 350 users falls well below the single-instance capacity of 2,000. Option C is wrong for the same over-provisioning reason and because it omits Australia entirely, which would leave that office without BES coverage.

Memory tip: Think "2,000 is the magic number" - if users at a location are under 2,000, one BES instance is all you need. Whenever you see a distractor doubling up servers at a site with only a few hundred users, it's a trap.
