Suggested answer: A, C

Explanation:

Explanation:

Explanation:

On-Demand: This is the default, pay as you go pricing model. When you use resources (for example, EC2 instances or services such as DynamoDB on demand) you pay a flat rate, and you have no longterm commitments. You can increase or decrease the capacity of your resources or services based on the demands of your application. On-Demand has an hourly rate, but depending on the service, can be billed in increments of 1 second (for example Amazon RDS, or Linux EC2 instances). On demand is recommended for applications with short-term workloads (for example, a four-month project), that spike periodically, or unpredictable workloads that canít be interrupted. On demand is also suitable for workloads, such as pre-production environments, which require uninterrupted runtimes, but do not run long enough for a commitment discount (Savings Plans or Reserved Instances).
