- A
Compute Savings Plans
Correct. Compute Savings Plans apply to any EC2 instance usage across any region (when scoped to region), regardless of instance family, and provide the flexibility to change instance families without any penalty, while offering substantial discounts over On-Demand pricing.
- B
EC2 Instance Savings Plans
Why wrong: Incorrect. EC2 Instance Savings Plans are locked to a specific instance family in a specific region. They do not allow changing instance families without losing the discount, making them unsuitable for the described requirement of switching instance families.
- C
Convertible Reserved Instances
Why wrong: Incorrect. Convertible Reserved Instances allow you to change the instance attribute (including instance family) but require an exchange process that may have constraints and typically offer lower discounts than Standard RIs or Savings Plans. They are less flexible than Compute Savings Plans for frequent or rapid changes.
- D
Standard Reserved Instances
Why wrong: Incorrect. Standard Reserved Instances are locked to a specific instance type and region for the duration of the term. They do not allow any changes to instance family, so they cannot meet the requirement of switching families during the contract period.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company runs a containerized application on Amazon ECS using a mix of Amazon EC2 On-Demand instances from different instance families (e.g., M5, C5, R5). The workload is consistent, and the company is willing to commit to a 1-year term to reduce costs. However, the team expects to change instance families within the next 12 months due to new hardware requirements and wants the flexibility to switch instance families without incurring a financial penalty. Which pricing option best meets these requirements?

Correct answer & explanation
Compute Savings Plans
Compute Savings Plans provide the most flexibility by applying a discounted hourly commitment (e.g., $10/hour) across any EC2 instance family, region, OS, or tenancy, and also cover Fargate and Lambda usage. Since the company expects to change instance families within the 1-year term, Compute Savings Plans allow switching without penalty, unlike instance-specific plans.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Convertible Reserved Instances
Why it's wrong here
Incorrect. Convertible Reserved Instances allow you to change the instance attribute (including instance family) but require an exchange process that may have constraints and typically offer lower discounts than Standard RIs or Savings Plans.

Incorrect. Standard Reserved Instances are locked to a specific instance type and region for the duration of the term. They do not allow any changes to instance family, so they cannot meet the requirement of switching families during the contract period.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse EC2 Instance Savings Plans with Compute Savings Plans, assuming instance-specific plans offer the same flexibility, but they fail to recognize that only Compute Savings Plans allow family changes without penalty or manual exchange.
Detailed technical explanation
How to think about this question
Compute Savings Plans apply a flexible hourly commitment that automatically covers the lowest-cost instance family in a region, and any usage above the commitment is billed at on-demand rates. Under the hood, AWS calculates the discounted rate based on the blended savings plan rate across all eligible compute usage, and switching instance families simply means the discount is applied to the new family's on-demand rate without any modification or exchange request. In a real-world scenario, a team migrating from C5 to R5 instances for memory-intensive workloads would see the Compute Savings Plan discount seamlessly apply to the new R5 instances at the same commitment level.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
