✓ Correct Answer & ExplanationKubernetes Core

Correct Answer

Configure an 'emptyDir' volume and mount it in both containers

Why This Answer Is Correct

Containers in the same Pod can all read and write the same files in the 'emptyDir' volume, making it the perfect choice for sharing data between a main app and a helper sidecar.
