Are you an aspiring Cisco certified network associate working on getting the CCNA certificate? By the end of chapter 8, you have covered a lot of routing and switching essentials. Take the test below and see just how prepared you are to tackle the final exam and test your understanding. Good luck!
OSPF will run a new DR/BDR election
SPF will run and determine which neighbor router is down.
OSPF will remove that neighbor from the router link-state database.
A new dead interval timer of 4 times the hello interval will start.
They both are link-state protocols.
They both use the global address as the source address when sending OSPF messages.
They both share the concept of multiple areas.
They both support IPsec for authentication.
They both have unicast routing enabled by default.
They both use the same DR/BDR election process.

Routing table
It is a link-state database that represents the network topology.
Its contents are the result of running the SPF algorithm.
When converged, all routers in an area have identical topology tables.
The topology table contains feasible successor routes.
The table can be viewed via the show ip ospf database command.
After convergence, the table only contains the lowest cost route entries for all known networks.
To send specifically requested link-state records
To discover neighbors and build adjacencies between them
To ensure database synchronization between routers
To request specific link-state records from neighbor routers
