Which of the following routing protocols should be implemented to create a route between a local area network and an ISP?
Correct Answer: A
BGP stands for Border Gateway Protocol, and it is a routing protocol that is used to exchange routing information between different autonomous systems (AS) on the Internet. An AS is a network or a group of networks that are under the same administrative control and share a common routing policy. BGP is used to create routes between local area networks and Internet service providers (ISPs), as well as between different ISPs. BGP is considered an exterior gateway protocol (EGP), as opposed to an interior gateway protocol (IGP) such as EIGRP, RIP, or OSPF, which are used to create routes within an AS.
