MPLS stands for?

• A. Multi-Protocol Label Switching
• B. Multi-Protocol Label Security
• C. Message Path Link System
• D. Multi-Protocol Layered Switching

Answer: (A)

MPLS stands for Multi-Protocol Label Switching. The main idea is to forward packets by using short labels attached at the edge of the network, and to swap those labels at each hop to determine the next forwarding action. This lets routers push packets along explicit paths quickly, without having to perform a full IP lookup at every step, which improves speed and enables efficient traffic engineering and VPN services. The “Multi-Protocol” part means the technique works with different network-layer protocols, not just IP, while “Label Switching” highlights the core mechanism of swapping labels to move packets through the network. The other options don’t fit the established term: there’s no “Security” in the name, and terms like “Message Path Link System” or “Layered” switching aren’t correct descriptors for MPLS.
