NSE 7 – Enterprise Firewall 7.0 — Question 1

Which three conditions are required for two FortiGate devices to form an OSPF adjacency? (Choose three.)

Answer options

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

Correct answer: A, B, D

Explanation

For two FortiGate devices to successfully establish an OSPF adjacency, the OSPF interface network types must match, the router IDs must be unique to prevent conflicts, and the authentication settings must align to ensure secure communication. The other options, while relevant to OSPF configuration, do not directly affect the establishment of adjacency.
