Refer to the Exhibit. Which switch will be the root bridge after the election process is complete? Answer: SW1

The switch with the lowest MAC address will become the root bridge

• The switch with the lowest MAC address will become the root bridge.
• This is because the root bridge is the switch with the lowest priority and the MAC address is used as the priority if the priority is not explicitly set.
• In the exhibit, SW1 has the lowest MAC address (00:00:00:00:00:01), so it will become the root bridge.

The root bridge is responsible for maintaining the Spanning Tree Protocol (STP) topology

The root bridge is responsible for maintaining the Spanning Tree Protocol (STP) topology. It does this by sending out Bridge Protocol Data Units (BPDUs) to all other switches in the network. These BPDUs contain information about the root bridge's priority, MAC address, and the cost to reach the root bridge. All other switches in the network use this information to determine their own role in the STP topology and to avoid creating loops.

STP prevents loops in the network by blocking redundant paths

STP prevents loops in the network by blocking redundant paths. It does this by creating a spanning tree, which is a loop-free topology that connects all of the switches in the network. The root bridge is the central point of the spanning tree, and all other switches connect to the root bridge either directly or indirectly. STP ensures that there is only one active path between any two switches in the network, which prevents loops.

The root bridge is elected through a process called the Bridge Protocol Data Unit (BPDU)

The root bridge is elected through a process called the Bridge Protocol Data Unit (BPDU). BPDUs are sent out by all switches in the network, and they contain information about the switch's priority, MAC address, and the cost to reach the root bridge. Switches use this information to determine which switch should be the root bridge. The switch with the lowest priority and the lowest MAC address will be elected as the root bridge.

BPDUs are sent out by each switch to advertise its own priority and the priority of the root bridge

• BPDUs are sent out by each switch to advertise its own priority and the priority of the root bridge.
• The priority of a switch is a value that is used to determine which switch will be the root bridge.
• The switch with the lowest priority will be elected as the root bridge.
• The root bridge is the central point of the spanning tree topology, and all other switches connect to the root bridge either directly or indirectly.
• By advertising its own priority and the priority of the root bridge, each switch helps to maintain the spanning tree topology and prevent loops.

The switch with the lowest priority will become the root bridge

The switch with the lowest priority will become the root bridge.

• The priority of a switch is a value that is used to determine which switch will be the root bridge.
• The switch with the lowest priority will be elected as the root bridge.
• The root bridge is the central point of the spanning tree topology, and all other switches connect to the root bridge either directly or indirectly.

By electing the switch with the lowest priority as the root bridge, the network ensures that there is a single root bridge and that the spanning tree topology is loop-free.

If two switches have the same priority, the switch with the lowest MAC address will become the root bridge

If two switches have the same priority, the switch with the lowest MAC address will become the root bridge.

• The MAC address is a unique identifier that is assigned to each switch.
• If two switches have the same priority, the switch with the lowest MAC address will be elected as the root bridge.
• This ensures that there is a single root bridge and that the spanning tree topology is loop-free.
