Exam N10-008 topic 1 question 318 discussion

A MPLS is a networking technology that allows data packets to be forwarded based on short path labels rather than long network addresses. This reduces the need for routing table lookups, as the packet forwarding decisions can be made independently of the network layer header. mGRE (Multipoint Generic Routing Encapsulation) is a tunneling protocol that allows multiple remote devices to be connected to a single virtual private network (VPN). It does not reduce routing table lookups. EIGRP (Enhanced Interior Gateway Routing Protocol) is a routing protocol used to exchange routing information between devices within a single autonomous system (AS). It does not reduce routing table lookups. VRRP (Virtual Router Redundancy Protocol) is a protocol used to provide network failover and redundancy. It does not reduce routing table lookups.

Multiprotocol Label Switching, or MPLS, is a networking technology that routes traffic using the shortest path based on “labels,” rather than network addresses, to handle forwarding over private wide area networks. As a scalable and protocol-independent solution, MPLS assigns labels to each data packet, controlling the path the packet follows. MPLS greatly improves the speed of traffic, so users don’t experience downtime when connected to the network.

MPLS is a networking technology that allows data packets to be forwarded based on labels with the shortest path rather than long IP network addresses. This reduces the need for routing table lookups, as the packet forwarding decisions can be made independently of the network layer header. With MPLS, you can manage a Software Defined-Wide Area Network (SD-WAN) entirely by a single software program, & have this layered over multiple types of network transport outside of standard routing procedures., This means you can use any of the other WAN connections you might want to such as switching, cellular, microwave, satellite, broadband, or even routing.

With MPLS, you can manage an SD-WAN entirely in software, plus layered over multiple types of network transport, meaning you can use any of the other WAN connections you might want to.

GPT picks (A) MPLS (Multiprotocol Label Switching): "(A) MPLS (Multiprotocol Label Switching): MPLS uses labels to make forwarding decisions rather than relying solely on the network layer header information. This label-based approach allows for faster and more efficient forwarding of packets, reducing the need to perform extensive routing table lookups at each hop. (B) mGRE (Multipoint Generic Routing Encapsulation): mGRE is a tunneling protocol and does not inherently reduce routing table lookups or perform forwarding decisions independently of the network layer header. (C) EIGRP (Enhanced Interior Gateway Routing Protocol): EIGRP is a routing protocol that operates at the network layer and is responsible for routing table lookups and forwarding decisions based on network layer information. (D) VRRP (Virtual Router Redundancy Protocol): VRRP is a protocol used for providing high availability by creating a virtual IP address shared among multiple routers. It does not perform packet forwarding decisions independently of the network layer header."
