   Your router receives four BGP routes for the same prefix. The routes have the following attributes: Route 1: local preference 200, AS path 3, MED 50. Route 2: local preference 200, AS path 2, MED 100. Route 3: local preference 150, AS path 2, MED 50. Route 4: local preference 150, AS path 3, MED 100. Which route will be selected as the best path?

   • ARoute 2, because it has the highest local preference and shortest AS path.
   • BRoute 1, because it has the highest local preference and lowest MED.
   • CRoute 3, because it has the lowest MED.
   • DRoute 4, because it has the lowest local preference.

   What is the primary reason iBGP-learned routes are not advertised to other iBGP peers?

   • ATo reduce the number of BGP sessions
   • BTo reduce the AS path length
   • CTo prevent routing loops within the AS
   • DTo ensure routes are advertised to eBGP peers

   What is a fundamental rule of iBGP regarding routes learned from an iBGP peer?

   • AThey are advertised to all other iBGP peers.
   • BThey are advertised only if the next hop is changed.
   • CThey are not advertised to other iBGP peers.
   • DThey are advertised only to eBGP peers.

   Your network has two eBGP paths to the same prefix from two different providers. Path 1 has an AS path length of 3 and a local preference of 200. Path 2 has an AS path length of 2 and a local preference of 150. Which path will be selected as the best path?

   • APath 2, because AS path length is evaluated before local preference.
   • BPath 1, because local preference is evaluated before AS path length.
   • CPath 1, because it has a longer AS path which indicates a more stable route.
   • DPath 2, because local preference is only considered for iBGP routes.
