A. B. C. D. E.BC.
Exterior routing protocols are used to determine the optimal path for routing traffic between autonomous systems (AS) or between networks that are under the control of different administrative domains. Exterior Gateway Protocol (EGP) and Border Gateway Protocol (BGP) are two common exterior routing protocols.
Option A is incorrect because exterior routing protocols are used to determine the optimal path between autonomous systems, not within an autonomous system.
Option B is correct because exterior routing protocols are designed to determine the optimal path between autonomous systems. BGP is the most commonly used exterior routing protocol for this purpose.
Option C is incorrect because while BGP is a commonly used exterior routing protocol, it is not the current standard. The current standard is BGP-4, which is the fourth version of BGP.
Option D is incorrect because EGP is an outdated exterior routing protocol and is not commonly used anymore. Most modern networking supports BGP for external routing.
Option E is incorrect because EIGRP is an interior routing protocol and is not used for external routing. Exterior routing protocols such as BGP are used for external routing.
