   Which statement accurately describes the BGP protocol?

   • ABGP is a distance-vector protocol that uses hop count as its primary metric for route selection.
   • BBGP is a link-state protocol that uses Dijkstra's algorithm to compute the shortest path to each destination.
   • CBGP is a path-vector protocol that exchanges reachability information and path attributes with peers over TCP port 179.
   • DBGP is a hybrid protocol that combines features of both distance-vector and link-state protocols, using UDP port 520 for updates.

   A Dell PowerSwitch receives two BGP routes to the same destination prefix. Route A has a local preference of 200 and an AS path of '65001 65002'. Route B has a local preference of 150 and an AS path of '65001'. Which route will be selected as the best path?

   • ARoute A, because it has the higher AS path length.
   • BRoute B, because it has the lower local preference.
   • CRoute B, because the AS path is shorter.
   • DRoute A, because local preference is compared before AS path length.
