   A router has two OSPF paths to 192.168.10.0/24: Path A has a cost of 100 and is learned from an area 0 router. Path B has a cost of 200 and is learned from an area 1 router. Both paths have the same prefix length. The router also has a static route to 192.168.10.0/24 with AD 1. What will the router do?

   • ALoad balance between Path A and the static route
   • BUse Path B because it is from a different area
   • CUse the static route because it has a lower administrative distance
   • DUse Path A because it has the lowest OSPF cost

   A router has a static route to 0.0.0.0/0 with AD 1, an OSPF route to 10.0.0.0/8 with cost 50, and an EIGRP route to 10.0.0.0/16 with metric 100. A packet destined for 10.0.1.1 arrives. Which route will be used?

   • AThe EIGRP route, because it is the longest prefix match.
   • BThe OSPF route, because it is the longest prefix that matches.
   • CThe default route, because it has the lowest administrative distance.
   • DThe default route, because it is the only route with a low AD.

   An EIGRP router has two paths to reach 172.16.10.0/24. Path A has a composite metric of 307200, and Path B has a composite metric of 332800. Both paths have the same prefix length. What will the router do?

   • ALoad balance across both paths
   • BInstall Path B as the successor route
   • CUse administrative distance to choose
   • DInstall Path A as the successor route

   A router has a static route to 10.0.0.0/8 and an OSPF route to 10.0.0.0/16. A packet destined for 10.0.1.1 arrives. Which route will the router use?

   • AThe static route, because it is more specific.
   • BThe static route, because it has a lower administrative distance.
   • CThe router will load-balance between the two routes.
   • DThe OSPF route, because it has a longer prefix.

   A network administrator configures a static default route on a router. The router also runs RIP and learns a default route via RIP. Which route will be installed in the routing table?

   • AThe RIP default route, because RIP is a dynamic protocol
   • BThe static default route, because it has a lower administrative distance
   • CBoth routes are installed and used for failover
   • DThe route with the lower metric
