What are roles that allow you to manage regulatory compliance standards?

Answer options:

A.Security Admin
B.Security Reader
C.Resource Policy Contributor
D.Security Assessment

Correct Answers: A and C
Option A & C are correct. The minimum set of roles for accessing the dashboard and managing standards is Resource Policy Contributor and Security Admin.
Option B & D are incorrect. To view compliance data, you need to have at least Reader access to the policy compliance data as well; so Security Reader or assessment alone won’t suffice.
