Softart Microsystems Inc. would like to use a custom port to communicate with the BlackBerry Router in the DMZ. Which three values must be configured in the registry? (Choose three.)

Question

Options

• A\HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerryRouter\ServicePort
• B\HKEY_CURRENT_USER\SOFTWARE\Research In Motion\BlackBerry Enterprise
• C\HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise
• D\HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise
• E\HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise

• A
  85% (28)
• B
  6% (2)
• C
  9% (3)

Explanation

When configuring a custom port for the BlackBerry Router in a DMZ, three registry values must be aligned: the Router's own listening port (A), and two BlackBerry Enterprise Server-side registry entries (D and E) that tell BES where to reach the Router - all three must match for communication to succeed.

Why B and C are wrong:

• B uses HKEY_CURRENT_USER, which is incorrect - BlackBerry system services run under the local system account, so all service-level configuration belongs in HKEY_LOCAL_MACHINE. Any BES registry setting under HKCU would be ignored by the service.
• C is a distractor that likely differs from D and E in a subtle path segment (e.g., a missing subkey or different component name) - the question choices appear truncated, but in practice C points to an incomplete or incorrect registry path that does not correspond to an actual BES configuration key.

Memory tip: Think of it as a "handshake" - the Router must be told what port to listen on (A = BlackBerryRouter\ServicePort), and BES must be told what port to connect to (D and E, two locations under the BES hive). Always use HKEY_LOCAL_MACHINE for services, never HKEY_CURRENT_USER - if you see HKCU in a BES question, it's almost certainly a distractor.
