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
✓
The task continues running as normal.
Non-essential containers can fail without affecting the task. Option A is wrong because only essential container failure stops the task. Option B is wrong because ECS will not restart a non-essential container by default; it depends on the task definition restart policy. Option D is wrong because the sidecar's CPU=0 means it can use up to the available CPU, but it still runs.
