Stp — Cisco CCNA (200-301) Practice Questions
Spanning Tree Protocol (STP) is an IEEE 802.1D Layer 2 protocol that prevents switching loops in networks with redundant paths by placing certain switch ports into a blocking state while keeping others forwarding. The CCNA 200-301 exam covers the STP election process, including how a root bridge is chosen based on bridge priority and MAC address, and how root ports and designated ports are determined on each segment. You must understand port states (blocking, listening, learning, forwarding) and the timers that control transitions between them. The exam also tests knowledge of Rapid STP (RSST, 802.1W), which significantly reduces convergence time and is the preferred implementation in modern Cisco networks.
