Show Suggested Answer

Suggested Answer: A

BGP is not chosen because it is more efficient than link-state protocols; in fact, link-state protocols like IS-IS and OSPF generally provide faster convergence and more efficient route calculation. BGP is used in data centers mainly because it is mature, well understood, supports both IPv4 and IPv6, and offers flexible policy control.
