A company has a production workload that runs 24/7 and a batch processing workload that runs for 2 hours each night. The batch job is fault-tolerant. The company wants to minimize costs for both workloads. Which combination of pricing models is most cost-effective?

Spot Instances for production and On-Demand for batch processing.

Reserved Instances for both production and batch processing.

Reserved Instances for production and Spot Instances for batch processing.

On-Demand for production and Reserved for batch processing.

A startup is migrating its on-premises infrastructure to AWS. The CFO wants to move from large upfront hardware purchases to a model where costs align directly with monthly usage and can be adjusted as the business grows. Which AWS approach best meets this requirement?

Purchase Reserved Instances for all workloads to lock in the lowest hourly rate.

Sign a 3-year Savings Plan for all compute to reduce the per-hour cost.

Deploy a hybrid architecture that keeps critical workloads on-premises to avoid cloud costs.

Use On-Demand instances and pay only for the compute capacity you consume each month.

What is the primary benefit of the pay-as-you-go pricing model for a startup with unpredictable traffic?

It requires a large upfront investment to secure capacity

It provides a fixed monthly cost that is easy to budget

It allows the startup to align costs with actual usage, avoiding over-provisioning

It offers the lowest possible price per hour compared to other models

Which statement best describes how AWS's economies of scale benefit individual customers?

Customers are guaranteed the lowest possible prices in the market

Customers pay lower prices because AWS spreads costs across many users

Customers receive dedicated hardware at no extra cost

Customers get priority support as a result of scale
