Question 1

What are the three fundamental drivers of cost in AWS?

Accepted Answer

Compute, storage, and outbound data transfer. These three categories determine the majority of your AWS bill across most services.

Question 2

What does AWS mean when it describes its pricing model as 'pay-as-you-go'?

Accepted Answer

You pay only for the resources you consume, with no upfront costs or long-term contracts required, allowing you to scale spending with actual usage.

Question 3

Which AWS pricing model offers up to 75% savings over On-Demand pricing in exchange for a 1- or 3-year commitment?

Accepted Answer

Reserved Instances (RIs). They offer significant discounts in exchange for committing to a specific instance type and term length.

Question 4

What type of EC2 pricing allows you to bid on unused AWS capacity and can be interrupted with a 2-minute warning?

Accepted Answer

Spot Instances. They offer up to 90% discount over On-Demand prices but can be terminated by AWS when capacity is needed elsewhere.

Question 5

What is the key difference between Compute Savings Plans and EC2 Instance Savings Plans?

Accepted Answer

Compute Savings Plans offer flexibility across any EC2 instance family, region, OS, and tenancy, as well as Fargate and Lambda. EC2 Instance Savings Plans are locked to a specific instance family and region but offer deeper discounts.
