To avoid loops in a switched network, the STP (Spanning Tree Protocol) protocol is used, which is based on an algorithm developed by Radia Perlman, called STA (Spanning Tree Algorithm). This algorithm creates a loop-free topology, selecting one of the switches in the network to operate as the central point of the topology, designated as the root bridge, and all other switches in the topology must then identify a single path to this root bridge, which is the path of least cost. Based on the characteristics of the STP protocol operation described in the route, evaluate the following statements.

The first step in the STP (Spanning Tree Protocol) process is to define a switch to be the Root Bridge.
The definition of the Root Bridge is performed based on the connection of the switches, with the switch that has the most ports being chosen.
After defining the ports that represent the best path to the Root Bridge, the remaining ports of the switches that allow the network loop will be blocked.
The ports that are blocked by the STP protocol will only be unblocked through a configuration command, such as 'no shutdown'.
