2. A router is participating in an OSPFv2 domain. What will always happen if the dead interval expires before the router receives a hello packet from an adjacent DROTHER OSPF router?
OSPF will run a new DR/BDR election.
SPF will run and determine which neighbor router is “down”.
A new dead interval timer of 4 times the hello interval will start.
*OSPF will remove that neighbor from the router link-state database.

3. Which three statements describe the similarities between OSPFv2 and OSPFv3? (Choose three.)
*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 use the same DR/BDR election process.
They both have unicast routing enabled by default.

4. Which OSPF component is identical in all routers in an OSPF area after convergence?
adjacency database
*link-state database
