What is the IEEE standard for the Classic Spanning Tree Protocol?

• A. 802.1X
• B. 802.1Q
• C. 802.1D
• D. 802.1W

Answer: (C)

The Classic Spanning Tree Protocol, also known as Spanning Tree Protocol (STP), is defined by the IEEE 802.1D standard. This protocol is crucial in network design as it prevents loops in Ethernet networks by creating a loop-free logical topology. It accomplishes this by blocking redundant paths and enabling a single active path between devices, thereby ensuring stability within network traffic. Understanding the role of STP within networking helps in maintaining optimal performance and minimizes the risk of broadcast storms that can arise from loops. This standard has formed the foundation for other protocols like Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP), both of which enhance the original design outlined in 802.1D.
