Answer: Reserved Instances, Savings Plans
## Explanation **Reserved Instances** and **Savings Plans** are the correct choices because: ### Reserved Instances - Provide significant cost savings (up to 72% compared to On-Demand pricing) - Offer 1-year or 3-year commitment terms, meeting the "at least 1 year" requirement - Guarantee capacity availability - No interruptions - instances run continuously ### Savings Plans - Provide flexible pricing model with similar savings to Reserved Instances - Offer 1-year or 3-year commitment terms - No interruptions to running instances - Can be applied across instance families and regions ### Why other options are incorrect: **Spot Instances**: These can be interrupted with 2-minute warning when AWS needs capacity back, so they don't meet the "cannot tolerate interruptions" requirement. **AWS Marketplace subscriptions**: These are for software licensing costs, not EC2 instance pricing optimization. **Dedicated Hosts**: While they provide physical server isolation, they don't inherently provide cost savings compared to Reserved Instances or Savings Plans for long-term workloads. Both Reserved Instances and Savings Plans provide the cost optimization needed while ensuring uninterrupted operation for the required 1-year minimum duration.
