Question

Options

• AIt requires an additional SRP
• BAll users on BlackBerry Enterprise Server software version 4.1.6 are disabled until migrated
• CEach BlackBerry Enterprise Server instance will have its own BlackBerry Domain
• DAll BlackBerry device users are migrated at the same time

• A
  78% (18)
• B
  9% (2)
• C
  4% (1)
• D
  9% (2)

Explanation

Option A is correct because each BlackBerry Enterprise Server instance requires its own unique SRP (Server Routing Protocol) key to authenticate and communicate with BlackBerry's relay infrastructure. Running two separate BES instances - one in Chicago (v4.1.6) and one in Los Angeles (v5.0) - means you need a second SRP key for the new server, even though they share the same SQL database.

Why the distractors are wrong:

• B is wrong because a phased migration specifically allows users on the older BES to keep functioning normally - they are never "disabled" simply because a newer version exists alongside it.
• C is wrong because sharing a single SQL database means both BES instances share one BlackBerry Domain, not separate ones. Separate domains would break the shared-database architecture described.
• D is wrong by definition - "phased migration" means users move in batches over time, which is the entire reason for running both versions simultaneously.

Memory tip: Think of an SRP key as each server's "passport" to reach BlackBerry's network - two servers always means two passports, regardless of whether they share other resources like a database.
