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
✓
Dropping all Linux capabilities except those required
Seccomp profiles restrict system calls, and dropping unnecessary Linux capabilities reduces the attack surface, both of which help prevent container escape.

- ✗
Running containers in privileged mode
Why it's wrong here
Incorrect; privileged mode increases escape risk.
