Nextair Corporation. has limited hardware resources available and is planning to perform an in- place upgrade of BlackBerry Enterprise Server software version 4.1.6 to version 5.0. What are two…

Question

Options

• AAll other locations with 4.1.6 BlackBerry Enterprise Servers must be upgraded immediately
• BIt will be more difficult to rollback
• CThere is additional cost of another SRP
• DThe SQL database must be hosted on two separate BlackBerry Enterprise Servers
• EThey will experience more downtime

• A
  8% (2)
• B
  72% (18)
• C
  4% (1)
• D
  16% (4)

Explanation

Performing an in-place upgrade means overwriting the existing BlackBerry Enterprise Server (BES) 4.1.6 installation on the same hardware rather than setting up a new parallel server. This is risky because if the upgrade fails or causes issues, reverting to 4.1.6 requires a full reinstall and database restoration - making rollback significantly more difficult (B). Additionally, since there is no secondary server to absorb traffic during the upgrade, users lose BlackBerry service for the entire duration of the process, resulting in greater downtime (E) compared to a side-by-side migration approach.

Why the distractors are wrong:

• A is false - other remote BES locations operate independently and are not forced to upgrade simultaneously.
• C is false - an in-place upgrade does not require an additional SRP (Server Routing Protocol key); you retain the same SRP for the same server.
• D is false - there is no requirement to split the SQL database across two BES servers for this type of upgrade; this is a fabricated constraint.

Memory tip: Think of in-place upgrades as a "one-way door" - once you walk through, going back is painful (B = Backtrack is hard) and everyone waits while the door is being replaced (E = Extended downtime). Side-by-side upgrades, by contrast, let you build a new door before removing the old one.
