Question 1 of 30

In a network utilizing Spanning Tree Protocol (STP), a switch receives a Bridge Protocol Data Unit (BPDU) from a neighboring switch with a Bridge ID of 32768 and a Port ID of 1. The local switch has a Bridge ID of 32768 and a Port ID of 2. If both switches have the same Bridge Priority, how does the local switch determine which switch will become the root bridge, and what will be the outcome if the local switch has a lower MAC address than the neighboring switch?

The local switch will become the root bridge due to its lower MAC address.

The neighboring switch will become the root bridge due to its higher Port ID.

The local switch will not participate in the election since both have the same Bridge ID.

The outcome is indeterminate as both switches have the same Bridge ID.
