Nextair Corporation has determined the hardware running BlackBerry Enterprise Server software version 4.1.6 will be insufficient to handle version 5.0. They plan to perform a cutover upgrade using…

Question

Options

• AThere is no downtime for other BlackBerry Enterprise Server software version 4.1.6 instances sharing
• BThey will save the cost of an additional SRP Identifier
• CThere is no need to back up the database prior to upgrade
• DThe SQL database must be hosted locally to the BlackBerry Enterprise Server

• A
  13% (5)
• B
  80% (32)
• C
  3% (1)
• D
  5% (2)

Explanation

Option B is correct because a cutover upgrade reuses the same hardware and existing server identity, meaning the organization retains its current SRP (Server Routing Protocol) Identifier. Obtaining a new SRP Identifier carries an additional cost, which is avoided entirely when upgrading in place rather than migrating to new hardware.

Why the distractors are wrong:

• A is incorrect because a cutover upgrade actually causes downtime - you're taking the existing server offline to upgrade it. A parallel/migration approach is what minimizes disruption to other instances.
• C is incorrect and dangerous advice; you should always back up the database before a major upgrade, regardless of strategy. No legitimate upgrade method eliminates this best practice.
• D is incorrect because SQL can be hosted remotely in both cutover and migration scenarios - this is not a requirement specific to the cutover approach.

Memory tip: Think "cutover = carry over" - you carry over the same hardware, same SRP Identifier, same cost. The moment you spin up new hardware (migration), you need a new SRP ID and pay for it.
