NSE 7 – Enterprise Firewall 6.2 — Question 10

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

Answer options

• A. OSPF costs match
• B. OSPF peer IDs match
• C. Hello and dead intervals match
• D. OSPF IP MTUs match
• E. IP addresses are in the same subnet

Correct answer: C, D, E

Explanation

The correct conditions for establishing an OSPF adjacency include matching Hello and dead intervals (C), identical OSPF IP MTUs (D), and ensuring that IP addresses are in the same subnet (E). Options A and B are not required for OSPF adjacency; the OSPF costs and peer IDs do not need to be the same for the adjacency to form.
