A container group runs a one-time import job that writes data to an external system. If the job succeeds, the container must stop and stay stopped. If the job fails, it should automatically retry by restarting. Which restart policy should the administrator choose?

Never

Never prevents any restart behavior. That means a failed job would not retry automatically, which conflicts with the requirement to restart on failure.

Always

Always restarts the container regardless of success or failure. That would cause a completed import job to start again even after successful completion, which is not the requirement.

Manual

Manual is not the standard ACI restart policy for an unattended job. It would leave the workload dependent on operator action instead of automatically retrying on failure.

What does this AZ-104 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: OnFailure — OnFailure is the correct restart policy for a one-time import job that should be retried only when the process exits with an error. It lets the container group stop cleanly after a successful execution, which prevents duplicate imports. At the same time, it automatically restarts the container when something goes wrong, which fits batch and job-processing patterns in Azure Container Instances. Why others are wrong: Always would rerun the job even after success, which could duplicate work or corrupt target data. Never would stop any retry behavior, leaving transient failures unrecovered. Manual is not the right unattended policy for an import task that should automatically retry on failure. The scenario is specifically describing failure-based restart behavior, which maps directly to OnFailure.
