In the given scenario, we have $4$ x Layer $2$ switches, where the MAC address and priority are provided for each one of them. Assuming all the links have the same default cost and port priorities:

Which switch is the root bridge in this topology $?$

Based on the root bridge selection, what will be the state of each of the given switchports $($from port A to port H$)$ as per spanning tree protocol $($STP$)?$

Options: Root $/$ Designated $/$ Non$-$Designated

Root Bridge:

A:

B:

C:

D:

E:

F:

G:
