Explanation
The correct answer is D. Spot Instances offer up to 90% cost savings compared to On-Demand pricing, making them the most cost-effective option. Because the training jobs can be interrupted and resumed without major issues, SageMaker's managed Spot training with automated checkpointing handles interruptions gracefully-the job resumes from the last checkpoint rather than restarting. Option A (Reserved Instances) require upfront commitment and are better suited for continuous, predictable workloads. Option B (On-Demand) provides no discount. Option C (SageMaker Savings Plans) offer discounts but not as significant as Spot pricing for interruptible workloads.
