• Question 467:

  A technician has been dispatched to investigate an issue where several users in the same aisle have stated they have had no network connection for over an hour. When the technician gets there, the network seems to be up and running. Which of the following should the technician do NEXT?

  A. Ask the users for more information, such as which applications were not functioning.
  B. Power-cycle the switch that the users share to clear out cached DNS records.
  C. Escalate the issue to the network administrator to have their domain credentials reset.
  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.

  ---

  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.
