Question

We typically troubleshoot networking issues using one of the two networking models: OSI or TCP/IP.

A potential Layer 1 problem can be broken strands of copper in a cable, either preventing a flow through a circuit or touching each other and thus resulting in lower resistance.
What type of Layer 1 problem is this?

Answer 1

Layer 1 problem is that it may have bad connectors and bad cables.

Explanation:

When in the first layer of TCP/IP problem has been occur that's mean there is any connection who might be fail and their may be some poor connection of cables.Cables can be bad and broken which can not permit the current to flow.
