Question

Which three requirements must be met for two FortiGate devices to establish an OSPF adjacency?

Choose three

A OSPF link costs match.
B OSPF interface priority settings are unique.
C OSPF interface network types match.
D Authentication settings match.
E OSPF router IDs are unique.

Explanation

OSPF neighbors must use compatible interface network types and matching authentication, because these settings affect the validity and processing of OSPF hello packets. Each OSPF router also requires a unique router ID. Interface cost affects path selection rather than adjacency formation, and equal interface priorities are allowed; priority is relevant to DR/BDR election.
