What is the purpose of the Spanning Tree Protocol (STP) in a network?

• A. To provide redundancy in an IP routing protocol
• B. To filter traffic based on MAC addresses
• C. To prevent looped paths in a switched network
• D. To manage VLAN configurations across multiple switches

Answer: (C)

The Spanning Tree Protocol (STP) is designed specifically to prevent looped paths in a switched network. In Ethernet networks, when there are multiple paths between switches for redundancy, the potential for loops arises. Loops can cause broadcast storms, multiple frame copies, and overall network degradation. STP operates by placing certain ports in a blocking state to eliminate these loops while still providing a single active path between any two network devices in the switched topology. This ensures that there is no infinite loop of data frames circulating through the network, which would consume bandwidth and can lead to network outages. By allowing only a single logical path between switches while maintaining the configuration to quickly adapt in case of a link failure, STP enhances network reliability and helps maintain optimal data flow.
