- A
On-Demand Instances
Why wrong: On-Demand Instances provide no long-term commitment but also no discount. This option fails to meet the cost-savings objective the company seeks.
- B
Reserved Instances
Why wrong: Reserved Instances provide significant discounts but are tied to a specific instance family and Region. Changing instance families or Regions would require purchasing new reservations, forfeiting the discount on the original reservation. This does not offer the flexibility the company requires.
- C
Spot Instances
Why wrong: Spot Instances offer large discounts but can be interrupted with little notice. They are intended for fault-tolerant, flexible workloads, not for steady predictable workloads that must run continuously.
- D
Compute Savings Plans
Compute Savings Plans provide the same discounts as Reserved Instances but with greater flexibility. They apply to any EC2 instance usage regardless of instance family, size, or Region, as long as the usage is within the committed dollar-per-hour amount. This matches the company's need for both cost savings and flexibility.
Quick Answer
The answer is Compute Savings Plans because they provide maximum flexibility for EC2 cost savings while allowing you to freely change instance families and AWS Regions during the commitment term. Unlike Reserved Instances, which lock you into a specific instance family and region, Compute Savings Plans apply a discounted hourly commitment across any EC2 instance, automatically covering usage changes without losing the discount. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of the trade-off between savings depth and flexibility—Reserved Instances offer higher discounts for rigid workloads, but Compute Savings Plans are the correct choice when you need to adapt. A common trap is choosing Convertible Reserved Instances, which still restrict you to exchanging within the same instance family category. Memory tip: think of Compute Savings Plans as a “flexible blanket” covering all EC2 instances, while Reserved Instances are a “tight jacket” for one specific type.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 steady, predictable workload on a diverse mix of Amazon EC2 instances spanning multiple instance families (e.g., M5, C5, R5) and AWS Regions. The company wants to maximize cost savings while retaining the ability to freely change instance families and Regions during the commitment term without losing the discount. Which AWS pricing model should the company use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Compute Savings Plans
Compute Savings Plans (D) offer the highest flexibility by applying a discounted hourly commitment across any EC2 instance family, size, OS, tenancy, and region, automatically covering usage changes without losing the discount. This matches the requirement to freely change instance families and regions during the term while maximizing savings over On-Demand pricing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Reserved Instances with Savings Plans, assuming RIs offer similar flexibility, but RIs are region- and family-specific, whereas Compute Savings Plans provide full flexibility across families and regions.
Detailed technical explanation
How to think about this question
Compute Savings Plans apply a per-hour spend commitment (e.g., $10/hour) and automatically discount any EC2 usage up to that commitment, including instances from M5, C5, R5 families across regions. Under the hood, AWS calculates the discounted rate based on the blended savings plan rate for each instance type, and any usage beyond the commitment is billed at On-Demand rates. This model is ideal for workloads with variable instance needs because it decouples the discount from specific instance attributes.
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.

Variation 1. A company runs multiple workloads on Amazon EC2 instances. They expect consistent usage for the next three years but want the flexibility to change instance families (for example, from M5 to C5) if performance requirements shift. Which AWS pricing model meets these requirements while providing a significant discount over On-Demand pricing?
medium- A.Reserved Instances (Standard)
- ✓ B.Compute Savings Plans
- C.EC2 Instance Savings Plans
- D.Spot Instances
Why B: Compute Savings Plans (Option B) offer a significant discount (up to 66%) over On-Demand pricing in exchange for a commitment to a consistent amount of compute usage (measured in $/hour) for a 1- or 3-year term. Unlike Reserved Instances, Savings Plans are flexible across instance families (e.g., M5 to C5), regions, OS, and tenancy, making them ideal for workloads that may need to change instance types over time while still receiving a discounted rate.
