In the planning stages for an OSPF deployment, which step can be taken to reduce router overhead by limiting the size of the link state databases, and LSA Type 1 and Type 2 propagation?

In the planning stages for an OSPF deployment, which step can be taken to reduce router overhead by limiting the size of the link state databases, and LSA Type 1 and Type 2 propagation?

• Use redundant links and alternate paths between routers.
• Increase hello and dead interval timers.
• Ensure that the interfaces of all routers are configured for area 0.
• Divide the OSPF network into multiple areas.

Explanation: As OSPF areas grow in size, the size of the LSDB grows and the number of type 1 and type 2 LSAs increases. Breaking an OSPF domain into multiple areas reduces the size of the LSDB and the number type 1 and 2 LSAs in each area.
