Establish the Most Probable Cause of the Problem

At this point, you should have discovered what the problem is and how it manifested based on the following issues:

  • Service outage/inaccessible
  • Slow service
  • Logging issues
  • Dropped sessions
  • Data corruption

The next step is to find the cause of the problem, for example:

  • Cabling problems
  • Connectivity between an Access Layer switch and a Distribution Layer switch, either in the server room or in the wiring closet
  • DoS attack on a system (e.g., router, switch, or server)
  • Software issue . . .
