How do OAuth2 scopes enable granular permissions in FastAPI versus role-based checks?
Tests OAuth2 scope granularity vs RBAC and FastAPI SecurityScopes. Strong answers mention JWT claim strings, SecurityScopes per endpoint, and that RBAC is coarse while scopes are fine-grained. Red flag: treating scopes as roles or skipping claim checks.
This tests deep understanding of OAuth2 scope semantics versus coarse RBAC and how FastAPI integrates them via dependency injection. A strong answer explains scopes as space-delimited JWT permission strings, uses SecurityScopes for declaring and validating required scopes per endpoint, and clarifies that RBAC assigns broad static user roles while scopes enable fine-grained, client-consented, request-level access control. Red flag: conflating scopes with user roles or blurring the boundary between authentication and authorization.
