Half the regional BlackBerry device users are based in Germany and the remaining half are spread evenly among the other two offices. What is the minimum number of BlackBerry Enterprise Server…

Question

Options

• AOne in each location
• BThree in Germany, two in Switzerland, two in Sweden
• CTwo in Germany, one in Switzerland, one in Sweden
• DTwo in each location

• A
  2% (1)
• B
  9% (4)
• C
  85% (40)
• D
  4% (2)

Explanation

Option C is correct because BlackBerry Enterprise Server (BES) capacity scales proportionally with user count. Germany hosts 50% of users - twice the load of each other office - so it requires two BES instances, while Switzerland and Sweden each hold 25% of users and need only one instance each, giving the minimum viable total of four servers.

Why the distractors are wrong:

• A (one per location) fails because Germany's doubled user load exceeds what a single BES instance can handle relative to the other offices.
• B (3/2/2) and D (2/2/2) both exceed the minimum - they over-provision Switzerland and Sweden, which only warrant one server each given their smaller user base.

Memory tip: Think "halves map to servers" - Germany gets half the users, so it gets double the servers (2); each remaining office gets half of Germany's share, so each gets half the servers (1). The ratio of users directly drives the ratio of BES instances.
