In FastAPI, which component is typically used to enforce role-based access control?
ABackground tasks
BDependency injection with role checks
CStatic files serving
DMiddleware that logs requests
Step-by-Step Solution
Solution:
  1. Step 1: Identify RBAC enforcement method

    FastAPI uses dependencies to inject logic that checks user roles before endpoint execution.
  2. Step 2: Exclude unrelated components

    Middleware logging, static files, and background tasks do not enforce access control.
  3. Final Answer:

    Dependency injection with role checks -> Option B
  4. Quick Check:

    RBAC enforcement = dependencies [OK]
Quick Trick: Use dependencies to check roles before endpoint runs [OK]
Common Mistakes:
MISTAKES
  • Confusing middleware logging with access control
  • Thinking static files handle RBAC
  • Assuming background tasks enforce roles
