A network administrator is troubleshooting a situation where two switches are connected to each other with two cables, and the network is experiencing broadcast storms. What is the most likely cause and the correct action?

The switches are configured with different VLANs; configure the same VLANs on both switches.

The two cables are creating a switching loop; enable Spanning Tree Protocol (STP) on both switches.

The switches have mismatched MTU settings; adjust the MTU to be consistent.
