Cevap

The technician should test the theory by inspecting and reconnecting the USB cable.
According to the CompTIA troubleshooting methodology, after establishing a theory of probable cause (Step 2), the technician must test the theory to determine the actual cause (Step 3). Inspecting and reconnecting the cable tests whether the physical connection is the issue.

Adım Adım Çözüm

Identify the current stage in the CompTIA 6-step troubleshooting methodology.
The technician has already gathered info (Step 1) and established a theory of probable cause (Step 2).
Determining the current phase dictates which step follows sequentially.
2
Select the next step in the standard sequence.
Step 3 is 'Test the theory to determine cause'.
Before creating a plan of action or implementing fixes, the technician must test the hypothesis to verify if the loose cable is indeed the root cause.
