Question

_____ was introduced by the IETF (Internet Engineering Task Force) in 1999 and enables μltiple types of Layer 3 protocols to travel over any one of several connection-oriented Layer 2 protocols.

A. IPv6
B. NAT
C. MPLS
D. BGP

Answer 1

MPLS, introduced by the IETF in 1999, allows various Layer 3 protocols to use multiple Layer 2 connection-oriented protocols, enhancing network management and efficiency.

Step-by-step explanation:

The technology MPLS (Multi-Protocol Label Switching) was introduced by the Internet Engineering Task Force (IETF) in 1999. MPLS enables multiple types of Layer 3 protocols to travel over any one of several connection-oriented Layer 2 protocols. It improves the speed and control of network traffic flow and makes it easier to manage network traffic for different service models. MPLS is widely used in supporting virtual private networks (VPNs), traffic engineering, and improving network resiliency.
