Answer: D - STP, or Spanning Tree Protocol, identifies and prevents topology loops and ensures that data flows properly though a single network path.

Key Takeaway: Spanning Tree Protocol is a link management protocol that provides path redundancy and prevents undesirable loops on the network. Multiple active paths between stations cause loops in the network, which leads to duplication of messages. To provide path redundancy, STP defines a tree that spans all switches in an extended network. It forces certain redundant data paths into a standby or blocked state.
