Arcitura Education S90.18 Exam - Topic 3 Question 122 Discussion

Actual exam question for Arcitura Education's S90.18 exam

Question #: 122
Topic #: 3

Service A requires certificates signed by a trusted certificate authority. The certificate authority publishes a Certificate Revocation List (CRL) on a frequent basis. As a result, some of the service consumers that were previously authorized to access Service A will not be able to after new CRLs are issued. How can this security requirement be enforced?

AA human security administrator needs to check the validity of each certificate with the certificate authority whenever Service A is accessed.

BAn intermediary can check against the CRL to determine whether a certificate provided by a service consumer is still valid.

CUsing certificates in such a scenario is not a valid option.

DNone of the above

A seems too slow, can't rely on humans for this.

I'm not entirely convinced that using certificates isn't a valid option, but I guess it depends on the context of the service.

I feel like I saw a similar question about certificate validation in one of our practice exams, and I think the intermediary approach was the right answer there too.

I think option B makes the most sense since intermediaries can automate the process of checking the CRL, which is more efficient.

I remember studying about CRLs and how they help in managing certificate validity, but I'm not sure if a human admin checking each certificate is practical.
