Actual exam question for Fortinet's NSE7_EFW-7.2 exam

Question #: 20
Topic #: 4

[All NSE7_EFW-7.2 Questions]

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

AOSPF interface network types match

BOSPF router IDs are unique

COSPF interface priority settings are unique

DOSPF link costs match

EAuthentication settings match

Show Suggested Answer

Suggested Answer: A, B

The Virtual Router Redundancy Protocol (VRRP) configuration in the exhibit indicates that 10.1.5.254 is set as the virtual IP (VRIP), commonly serving as the default gateway for the internal network (A). With vrrp-virtual-mac enabled, both FortiGates would use the same virtual MAC address, ensuring a seamless transition during failover (B). The VRRP domain does not use the physical MAC address (C), and the priority settings indicate that FortiGate-A would be the primary router by default due to its higher priority (D).

Wait, are we sure the OSPF interface priority settings don't matter? I mean, how else are the devices going to decide who becomes the designated router?

Hold up, you guys are forgetting the most important requirement - the OSPF interface network types need to match. Otherwise, the devices won't even be able to talk to each other!

I agree with Franchesca, A, B, and E are the key requirements. Who cares about unique interface priorities or matching link costs? That's just overthinking it.

Hmm, I think D is also important for OSPF adjacency, since the link costs need to match for the devices to form a proper adjacency.

I believe A, B, and E are the correct conditions for OSPF adjacency. The interface network types, unique router IDs, and authentication settings need to match.
