   What is the purpose of a feasible successor in EIGRP?

   • AIt is a route that is advertised to neighbors but never installed in the routing table.
   • BIt is the primary route used to forward traffic to the destination.
   • CIt is a route learned from a neighbor with a higher advertised distance than the successor.
   • DIt is a backup route that is guaranteed to be loop-free and can be used immediately if the successor fails.

   What is the purpose of the 'network' command in OSPFv2 configuration?

   • AIt defines which interfaces participate in OSPF and assigns them to an area.
   • BIt enables OSPF authentication on an interface.
   • CIt sets the OSPF cost for an interface.
   • DIt assigns the router ID for the OSPF process.

   Which statement correctly describes a fundamental difference between EIGRP and OSPF?

   • AEIGRP is a link-state protocol that builds a complete network topology map, while OSPF is a distance vector protocol that relies on hop counts.
   • BBoth EIGRP and OSPF are link-state protocols, but EIGRP uses a higher default administrative distance than OSPF.
   • CEIGRP and OSPF both use the Bellman-Ford algorithm, but EIGRP adds a feasibility condition to prevent loops.
   • DEIGRP is an advanced distance vector protocol that sends partial updates, while OSPF is a link-state protocol that floods link-state advertisements to build a topology map.

   What is the purpose of the 'area filter-list' command in OSPF?

   • AIt filters external Type 5 LSAs.
   • BIt changes the OSPF cost of routes.
