Fortinet Exam NSE7_NST-7.2 Topic 1 Question 4 Discussion

Actual exam question for Fortinet's NSE7_NST-7.2 exam
Question #: 4
Topic #: 1
[All NSE7_NST-7.2 Questions]

Exhibit.

Refer to the exhibit, which contains partial output from an IKE real-time debug.

The administrator does not have access to the remote gateway.

Based on the debug output, which configuration change can the administrator make to the local gateway to resolve the phase 1 negotiation error?

Show Suggested Answer Hide Answer
Suggested Answer: B

Analyzing Debug Output:

The debug output shows multiple proposals with encryption algorithms like AES CBC and hashing algorithms like SHA256.

The negotiation failure (no SA proposal chosen) suggests that there is a mismatch in the encryption or hashing algorithms between the local and remote gateways.

Configuration Change:

To resolve the phase 1 negotiation error, the local gateway needs to include a compatible proposal.

Adding AES256-SHA256 to the phase 1 proposal configuration ensures that both gateways have a matching set of encryption and hashing algorithms.

Hey, at least the admin has access to the debug output. That's more than most of us have when troubleshooting VPNs!

A) AESCBC-SHA2? Sounds like a fancy encryption algorithm, but I'm not sure it's the right choice here.

B) Definitely AES256-SHA256. That's the industry standard for secure VPNs these days.
