B) STP examines the possible paths between all other bridges.
C) STP disables links that are not part of a shortest path.
D) STP begins to block BPDUs on non-designated ports.

The first step in selecting paths through a network using Spanning Tree Protocol is for STP to select the root bridge or the master bridge. Once the root bridge is selected, the network topology is mapped, and the shortest paths from each bridge to the root bridge are determined. The root bridge is the bridge with the lowest bridge ID, and it is responsible for propagating BPDUs (Bridge Protocol Data Units) that are used to identify the root bridge, calculate the path cost, and prevent loops in the network.
