  D. Close and document the service call, as there was no actual issue affecting the users.
  A. Ask the users for more information, such as which applications were not functioning.

  ---

  Explanation Explanation/Reference:Because the system was up and running when the technician reached there, he can ask for applications that were not working or can ask for more information so that he can isolate the problem. Power cycling will not help because the system is already up and recycling can wipe out logs. Escalation will also not help because the system is now up and running. Closing the call will be unfair because the same instance can occur again.
