Fortinet Exam NSE8_812 Topic 1 Question 27 Discussion

Actual exam question for Fortinet's NSE8_812 exam
Question #: 27
Topic #: 1
[All NSE8_812 Questions]

An administrator has configured a FortiGate device to authenticate SSL VPN users using digital certificates. A FortiAuthenticator is the certificate authority (CA) and the Online Certificate Status Protocol (OCSP) server.

Part of the FortiGate configuration is shown below:

Based on this configuration, which two statements are true? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, D

Bis correct because the OCSP check of the certificate can be combined with a certificate revocation list (CRL). This means that the FortiGate will check the OCSP server to see if the certificate has been revoked, and it will also check the CRL to see if the certificate has been revoked.

Dis correct because if the OCSP server is unreachable, authentication will succeed if the certificate matches the CA. This is because the FortiGate will fall back to using the CRL if the OCSP server is unreachable.

The other options are incorrect. Option A is incorrect because OCSP checks can go to other OCSP servers, not just the FortiAuthenticator. Option C is incorrect because OCSP certificate responses can be cached by the FortiGate.

If the OCSP server is down, authentication should fail. Can't just rely on the CA certificate match.

That's correct. The FortiGate will still allow authentication if the OCSP server is down as long as the certificate matches the CA.

I'm not sure about that. I think A and D are the correct answers because OCSP checks will always go to the FortiAuthenticator and if the server is unreachable, authentication will succeed if the certificate matches the CA.

Haha, imagine if OCSP responses were never cached. The FortiGate would be flooded with requests!

I agree with you, Cassie. The OCSP check can be combined with a certificate revocation list and if the server is unreachable, authentication will still succeed.

The OCSP check can be combined with a certificate revocation list - good to have both for better security.

That's true, having both the OCSP check and certificate revocation list adds an extra layer of security.

OCSP checks will always go to the configured FortiAuthenticator. That makes sense since it's the CA.
