A. B. C. D.C
When a network consists of multiple switches, a hierarchical structure is established with a root bridge at the top. The root bridge is responsible for controlling the flow of traffic and ensuring that there are no loops in the network topology.
In the event that the primary root bridge experiences a power loss, one of the other switches in the network will take over as the root bridge. This is determined by the Bridge ID, which is a combination of the Bridge Priority and the MAC address of the switch. The switch with the lowest Bridge ID will become the new root bridge.
In this scenario, since all switches are configured with default values, the Bridge Priority of all switches is set to the default value of 32768. The MAC addresses of the switches are:
To determine which switch will become the new root bridge, we need to calculate the Bridge ID for each switch. This is done by adding the Bridge Priority and the MAC address together.
The Bridge ID for each switch is:
The switch with the lowest Bridge ID is switch 0004.9A1A C182, so it will become the new root bridge if the primary root bridge experiences a power loss. Therefore, the correct answer is C. switch 0004.9A1A C182.
