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

AOCSP checks will always go to the configured FortiAuthenticator

BThe OCSP check of the certificate can be combined with a certificate revocation list.

COCSP certificate responses are never cached by the FortiGate.

DIf the OCSP server is unreachable, authentication will succeed if the certificate matches the CA.

Show Suggested 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 This means that the FortiGate will check the OCSP server to see if the certificate has been revoked, and it will also check the CRL to see if the certificate has been revoked.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.

I disagree, I believe the correct answer is D) If the OCSP server is unreachable, authentication will succeed if the certificate matches the CA.

The OCSP check is a smart move, but I wonder if the FortiAuthenticator can handle the load. Guess we'll find out if the server gets hammered!

I hope the FortiAuthenticator can handle the load, otherwise, we might have some issues.
