A Systems Manager Automation runbook must restart services on 200 managed nodes. Operations wants at most ten target executions running concurrently and wants the rollout to stop starting additional target executions after its configured error threshold is exceeded. Which settings should it use? Select 2 answers.

1. Set the multi-target Automation maximum concurrency to 10.
2. Set only the runbook step onFailure behavior and omit the multi-target maximum-errors control.
3. Configure maximum errors to the approved failure threshold and account for already-running executions during failure handling.
4. Set only the per-step execution timeout and leave target concurrency at its default.
5. Set maximum concurrency to 200 and expect maximum errors to limit normal parallel execution to ten.
