Answer: B, E

Explanation:

The RIB (Routing Information Base) is a database of routing prefixes that includes all learned routes, such as those from dynamic routing protocols, static routes, and directly connected routes. The FIB (Forwarding Information Base), on the other hand, is used to make IP destination prefix-based switching decisions and contains only the best path as determined by the routing protocol, which is used to forward packets12345.
