   A large enterprise is migrating from OSPF to IS-IS. During the migration, both protocols will run simultaneously on all routers. The network team needs to ensure that traffic uses the OSPF paths until IS-IS is fully deployed, and then switch to IS-IS paths without a service interruption. Which routing policy approach should be used?

   • ARedistribute OSPF routes into IS-IS and IS-IS routes into OSPF to create a single routing table.
   • BSet a higher preference for OSPF routes and a lower preference for IS-IS routes, then change the preference when the migration is complete.
   • CConfigure OSPF and IS-IS with the same preference and rely on the metric to select the best path.
   • DUse a firewall filter to block IS-IS routes from being installed in the routing table until the migration is complete.

   An OSPF network has a router that is not forming an adjacency with its neighbor. The `show ospf interface` command shows the interface is up and the network type is broadcast. The `show ospf neighbor` command shows the neighbor in `Down` state. Which two commands should the engineer use to further isolate the issue?

   • A`show ospf statistics` and `show ospf overview`
   • B`show ospf database` and `show route protocol ospf`
   • C`show ospf neighbor detail` and `show ospf interface detail`
   • D`show ospf log` and `show log messages`
