A long training job can tolerate interruption if progress is saved. Which two features support a cost-conscious SageMaker training design? Select 2 answers.

1. Keep the only checkpoint on ephemeral local storage with no persistence.
2. Assume Spot capacity cannot be interrupted.
3. Configure supported checkpoints and verify resume behavior.
4. Use Managed Spot Training for a compatible workload.
5. Remove the maximum training duration so failed jobs consume resources forever.
