Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Running containers as a non-root user
Running as non-root user, dropping unnecessary Linux capabilities, and using AppArmor/SELinux profiles are key container security best practices. Running as root defeats isolation; privileged containers grant excessive host access.
