Which of the following describes BGP?

An interior gateway protocol
An exterior protocol that manages paths for data
A protocol that only connects local networks
A type of subnet mask

The correct answer is: An exterior protocol that manages paths for data

BGP, or Border Gateway Protocol, is an essential protocol used for routing data between different autonomous systems on the internet, which makes it an exterior protocol. It operates at a higher level than interior gateway protocols, focusing on inter-domain routing rather than just navigating within a single local network or organization. BGP is responsible for determining the most efficient paths for data, facilitating communication between disparate networks by making routing decisions based on various attributes such as path length and network policies. The ability of BGP to manage paths efficiently is pivotal for maintaining the stability and performance of the global internet, making it an integral part of internet infrastructure. This functionality is what distinguishes it from other protocols that might focus solely on local traffic or subnetting.
