What protocol or technology disables redundant paths to eliminate Layer 2 loops?

  • VTP
  • STP
  • EtherChannel
  • DTP

Explanation: Spanning Tree Protocol (STP) is a loop-prevention network protocol specifically designed to eliminate Layer 2 loops in redundant switched networks by intentionally identifying and blocking redundant physical paths to ensure that only one logical path exists between any two devices at a time, while still maintaining the ability to automatically unblock those paths if an active link fails.
