Question 1 of 30

In a large enterprise network, the network engineer is tasked with optimizing the OSPF (Open Shortest Path First) routing protocol configuration. The network consists of multiple OSPF areas, including a backbone area (Area 0) and several non-backbone areas. The engineer needs to determine the best approach to minimize routing table size and improve convergence times. Which configuration should the engineer implement to achieve these goals while ensuring efficient inter-area routing?

Configure a summary route at the Area Border Routers (ABRs) to aggregate routes from non-backbone areas into the backbone area.

Enable OSPF route redistribution between different routing protocols without any filtering.

Use a totally stubby area configuration to prevent external routes from being advertised into the area.

Implement a virtual link between two non-contiguous areas to maintain OSPF area hierarchy.
