Multiple instances of the BlackBerry MDS Connection Service have been installed. What can be done to maximize performance output from each of these instances? (Choose one)

Question

Options

• AConfigure hardware load balancing
• BCreate a BlackBerry Router pool
• CConfigure automatic connections failover
• DSpecify application distribution settings
• ECreate a BlackBerry Administration Service pool

• A

• B

• C
  11% (4)
• D
  3% (1)
• E
  3% (1)

Explanation

Hardware load balancing (A) is correct because when multiple MDS Connection Service instances are deployed, distributing incoming traffic across them via a hardware load balancer ensures each instance operates at peak efficiency - no single instance becomes a bottleneck while others sit idle.

Why the distractors are wrong:

• B (BlackBerry Router pool): Router pools address routing redundancy and failover, not performance distribution across MDS instances.
• C (Automatic connections failover): Failover is a high-availability strategy for continuity when an instance fails - it doesn't maximize throughput across running instances.
• D (Application distribution settings): This controls which applications connect through which services, not how load is balanced across identical MDS instances for performance.
• E (BlackBerry Administration Service pool): BAS pools are for administrative redundancy and HA, completely separate from MDS Connection Service performance tuning.

Memory tip: Think "multiple = balance" - whenever a question pairs multiple instances with maximize performance, the answer is almost always load balancing. Pools and failover serve availability; load balancing serves performance.
