   What is the purpose of BGP multipath?

   • ATo resolve the next hop using multiple routing tables
   • BTo select the best path based on the lowest MED value
   • CTo prevent BGP from advertising multiple paths
   • DTo allow multiple BGP routes to the same destination to be installed in the routing table for load balancing

   A network engineer is troubleshooting a BGP route that is not active. The route's next hop is 10.10.10.1. The routing table has a route for 10.10.10.0/24 via OSPF with a next hop of 172.16.1.1. The route for 172.16.1.0/30 is a static route pointing to interface ge-0/0/0. The engineer checks the interface and it is up. However, the BGP route is still inactive. What is the most likely cause?

   • AThe BGP next hop 10.10.10.1 is not reachable via OSPF
   • BThe BGP route has a higher preference than the OSPF route
   • CThe OSPF route for 10.10.10.0/24 has been filtered by a policy
   • DThe static route for 172.16.1.0/30 has a next hop that is not directly connected

   A router has a BGP route for 10.0.0.0/8 with a next hop of 192.168.1.1. It also has an OSPF route for 192.168.1.0/24 with a metric of 10, and a static route for 192.168.1.0/24 with a preference of 5. The BGP route is not being used for forwarding. Which route is being used to resolve the BGP next hop, and why?

   • AThe OSPF route, because OSPF is an IGP and always preferred over static routes
   • BThe OSPF route, because it has a lower metric than the static route
   • CThe static route, because it has a lower preference value than OSPF
   • DNeither route, because BGP next hops are always resolved by the BGP table itself

   A router has two eBGP paths to 10.0.0.0/8. Path 1 has a next hop of 192.168.1.1, an AS path of '65001 65002', and a local preference of 150. Path 2 has a next hop of 192.168.2.1, an AS path of '65001 65003', and a local preference of 150. Both next hops are reachable. The router is configured with 'multipath' for eBGP. What will the router do?

   • AInstall both paths in the forwarding table and load balance traffic
   • BInstall only Path 1 because it has a lower next-hop IP address
   • CInstall both paths but only use Path 1 for forwarding
   • DInstall only Path 2 because it has a higher next-hop IP address
