Comprehensive and Detailed Explanation From Exact Extract:

STP (Spanning Tree Protocol) is a Layer 2 standard protocol that prevents switching loops in Ethernet networks by creating a loop-free logical topology. It can automatically block and unblock redundant paths based on network changes, ensuring reliability and avoiding broadcast storms.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Ethernet Loop Prevention and Switching Protocols”:

“STP is a standard Layer 2 protocol used to detect and prevent network loops, enhancing network stability in switched topologies.”

Other options:

B. SIP is a signaling protocol used in VoIP.

C. RTSP is for media streaming control.

D. BGP is a routing protocol, not for Layer 2 loop prevention.
