[All NSE7_NST-7.2 Questions]

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

Show Suggested Answer Hide Answer
Suggested Answer: C

Capturing ESP Traffic:

ESP (Encapsulating Security Payload) traffic is associated with IPsec and is identified by the protocol number 50. To capture ESP traffic, you need to filter packets based on this protocol.

In this specific case, you also need to filter for the host associated with the VPN tunnel, which is 10.200.3.2 as indicated in the exhibit.

Sniffer Command:

The correct command to capture ESP traffic for the VPN named DialUp_0 is:

diagnose sniffer packet any 'esp and host 10.200.3.2'

This command ensures that only ESP packets to and from the specified host are captured, providing a focused and relevant data set for troubleshooting.

Wait, is 'B) OSPF interface priority settings are unique' a real thing? I feel like that's just asking for trouble. Let's stick to the basics, folks!

Okay, let's see... C) and E) are definitely must-haves, and I'd go with D) as well. B) OSPF interface priority seems a bit overkill for this, but what do I know?

Haha, don't forget to check your OSPF link costs, Susana! Can't have those mismatched or your adjacency is toast.

I agree with C) and E), and I think D) Authentication settings should also match. Got to keep those devices secure, you know?

Definitely need C) OSPF interface network types to match, and E) OSPF router IDs to be unique. But I'm not sure about the other options - what do you guys think?

I agree with you, Ammie. Those conditions make sense for two FortiGate devices to form an OSPF adjacency.

I think the three conditions are OSPF link costs match, OSPF interface network types match, and OSPF router IDs are unique.
