Atechnician has been asked to troubleshoot a simple network problem that seems to be caused by software. which troubleshooting approach should be used?

top-down approach should be used.

Explanation:

Top-down troubleshooting approach to a network problem starts from the uppermost network layer and goes down to the deeper layers as the problem continues.

If a layer is in good condition but not all the upper layers, technician can conclude that the problem is within the layer which is above the working layer.

The approach is generally used when it is believed that the problem is within the application layer.  A simple network problem that seems to be caused by software looks an application layer problem, therefore top-down approach is a good method in this case.
