The answer is to sell them on the Reserved Instance Marketplace. This is the correct choice because the AWS Reserved Instance Marketplace allows you to recoup cost from unused Reserved Instances by listing them for sale to other AWS users, effectively transferring the remaining value of the upfront payment. AWS does not offer refunds or allow you to freely modify the attributes of a standard Reserved Instance once purchased, so the Marketplace is the only official mechanism to recover your investment when your infrastructure needs change. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of AWS cost management tools and the distinction between refunds, modifications, and marketplace sales—a common trap is assuming you can simply cancel or get a refund for an unused RI. A helpful memory tip: think of the Marketplace as a "resale shop" for your cloud commitments, not a return counter.
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 has unused Reserved Instances that don't match their current infrastructure. What option allows them to recoup some cost from unused RIs?
Why wrong: Reserved Instances cannot be converted to Spot Instances — they're different purchasing mechanisms.
B
Sell them on the Reserved Instance Marketplace
Standard RIs (not Convertible) can be listed on the RI Marketplace, allowing other AWS customers to purchase the remaining term at a seller-defined price.
C
Request a refund from AWS for unused RI capacity
Why wrong: AWS doesn't provide refunds for unused Reserved Instance capacity — the RI Marketplace is the mechanism for recovering value.
D
Transfer them to another AWS account for free
Why wrong: RIs can be sold on the Marketplace (with fees) but not freely transferred between accounts.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sell them on the Reserved Instance Marketplace
The AWS Reserved Instance Marketplace allows customers to sell unused Reserved Instances (RIs) to other AWS users, enabling them to recoup some of the upfront costs. This is the only option that directly addresses the need to recover costs from RIs that no longer match the current infrastructure, as AWS does not offer refunds or free transfers for unused RIs.
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 may assume AWS offers refunds or free transfers for unused RIs, but the only cost-recovery option is selling them on the Reserved Instance Marketplace, which involves a marketplace fee and is subject to availability of buyers.
Detailed technical explanation
How to think about this question
The Reserved Instance Marketplace operates as a third-party exchange where sellers list their RIs with remaining term and upfront payment, and buyers purchase them at a price set by the seller (subject to AWS’s standard RI pricing). The seller receives the prorated value of the upfront payment minus a 12% transaction fee charged by AWS. This mechanism is governed by the AWS Customer Agreement, which explicitly states that RIs are non-refundable and non-transferable except through the Marketplace.

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.
