• The extended system ID

• The MAC address of the switch

• The bridge ID

The root bridge in STP will be the switch with the:

• Highest port priority

The port closest to the Root bridge in terms of least overall cost (best path) to the root bridge is the:

• Designated port

• Blocked Port

• Root Port

• Routed port
