Explanation
STP (Spanning Tree Protocol) was specifically designed to prevent Layer 2 loops in Ethernet networks with redundant links. It does so by placing redundant ports into a Blocking state, ensuring only one active path exists between any two network segments at a time, creating a loop-free tree topology. VSS (Virtual Switching System) is a Cisco technology for combining two physical switches into one logical switch. VLANs segment broadcast domains but do not inherently prevent loops. vPC (Virtual Port Channel) is a Cisco Nexus technology for multi-chassis link aggregation.
