Question

Options

• ABoth BlackBerry Enterprise Server instances can be managed in the same BlackBerry Domain
• BIt allows time for testing beforemigrating all BlackBerry device users
• CBlackBerry devices will not require new service books
• DThe cost of an additional SRP Identifier is saved

• A
  3% (1)
• B
  74% (26)
• C
  9% (3)
• D
  14% (5)

Explanation

A phased migration - running the old version (4.1.6) in New York while piloting the new version (5.0) in Toronto - gives the IT team time to validate BES 5.0 behavior, identify issues, and refine the process before committing all users, making B correct.

Why the distractors are wrong:

• A is incorrect because the two BES instances run in separate BlackBerry Domains (each has its own SQL Server in its own location); a shared domain requires a shared database.
• C is incorrect because upgrading from BES 4.1.6 to 5.0 does require new service books to be pushed to devices to reflect the new server configuration.
• D is incorrect because each BES instance requires its own SRP (Server Routing Protocol) Identifier - a second instance means a second SRP ID cost, not a saving.

Memory tip: Think of a phased migration as a "pilot program" - the whole point is controlled testing before full rollout, which maps directly to answer B. If you see "phased" in a migration question, think testing and risk reduction.
