Click the Exhibit button. Exhibit is Missing Referring to the exhibit, which OSPF feature would connect Area 2 to Area 0?

Route summarization is used to reduce the number of routes advertised between OSPF areas, not to establish connectivity between disconnected areas.

Equal-cost multipath (ECMP) allows a router to use multiple paths of equal cost to reach a destination, which is a load-balancing feature, not a connectivity mechanism for OSPF areas.

An OSPF virtual link is used when a non-backbone area needs to connect to Area 0, but it does not have a direct physical connection. The virtual link establishes a logical connection through an intermediate transit area, allowing Area 2 to reach the OSPF backbone Area 0.

Database synchronization refers to the process of exchanging LSAs between OSPF routers to ensure consistent routing information, which is a general OSPF process, not a specific feature for connecting a disconnected area to the backbone.
