Question
In the current scenario the company has two BlackBerry Enterprise Server instances, one in New York and one in London. Ten BlackBerry device users in the Los Angeles office are on the BlackBerry Enterprise Server in London. The latency has increased to 150 ms between the Microsoft Exchange Server in Los Angeles and the BlackBerry Enterprise Server in London, and users in Los Angeles are experiencing message delays. The company decides to move the BlackBerry Enterprise Server to the Los Angeles office. What would be the impact to the London office? (Choose one)
Options
- AThe users will be unable to receive email
- BThe users will be unable to synchronize PIM items
- CThe users are likely to experience mail delays
- DThe users will be unable to accept calendar invitations
- EIt will take less time for messages to get to the users

Explanation
Moving the London BES to Los Angeles increases the physical and network distance between London office users and their BES, introducing higher latency - causing mail delays similar to what LA users experienced before the move. This is why C is correct: the problem isn't eliminated, it's shifted to the London users.
Why the distractors are wrong:
- A, B, D: These all describe complete loss of functionality (email, PIM sync, calendar invitations). BES doesn't stop working due to latency - it degrades, not fails. Users can still receive email and sync data, just slowly.
- E: This is the opposite of reality for London users. Moving the BES away from London adds network hops, increasing travel time for their messages.
Memory tip: Think of BES as a middleman sitting between your phone and your Exchange server. Moving the middleman closer to one office always moves it farther from another - you're not solving latency, you're reassigning who suffers it.
