Explanation

Option B is correct because deploying the new BlackBerry Enterprise Server (BES) in Vancouver and redistributing users from the overloaded New York server achieves two critical performance goals simultaneously: it balances the user load across servers and places the BES geographically closer to western North American users, reducing WAN latency and improving connection quality. BES performance degrades when a single server handles too many users or when users are geographically distant from their assigned server.

Why the distractors fail:

• A & C both add to or create a second server in New York, which doesn't help western North American users with latency - they're still connecting across the continent.
• D (Los Angeles) may seem logical, but the question implies Vancouver has an existing user base that justifies local placement; Los Angeles users would likely be moved to Vancouver rather than requiring their own dedicated server at this stage.
• E is geographically absurd - routing Los Angeles traffic through London adds enormous latency and defeats the purpose entirely.

Memory tip: Think "users should live close to their BES." When you see a BES performance question, look for the answer that both offloads an overloaded server AND places the new server nearest the users being migrated - that combination is always the right call.
