The AWS Certified Cloud Practitioner (CLF-C02) exam tests pricing and billing through Domain 4: Billing, Pricing, and Support (12%): the pricing models (On-Demand, Reserved, Spot, Savings Plans), the cost tools (AWS Budgets, Cost Explorer, the pricing calculator), consolidated billing through AWS Organizations, and the support plans.
Last updated August 2026.
Domain 4 is the smallest CLF-C02 domain at 12% of scored content, roughly six of the 50 scored questions. But pricing literacy earns marks beyond it: Domain 1 (Cloud Concepts, 24%) covers cloud economics, including the shift from capital expenditure to operating expenditure and the consumption-based model, and those questions lean on the same ideas. Between the two, how-AWS-charges thinking touches closer to a fifth of the exam.
It is also the fastest material on the paper to lock down. The models, tools, and plans below are a finite list with clean one-line jobs, which makes Domain 4 the classic "cheap marks" domain: an afternoon of focused study covers it end to end.
Domain weight and scope from the official AWS Certified Cloud Practitioner (CLF-C02) exam guide.
CLF-C02 tests the models at a conceptual level: given a described workload, pick the model that fits. No math, no rate cards.
| Model | Commitment | Reach for it when |
|---|---|---|
| On-Demand | None, pay per use | Unpredictable or short-lived workloads, or you are just starting out |
| Reserved | 1 or 3 years, a specific instance configuration | Steady-state workloads you can predict far ahead |
| Savings Plans | 1 or 3 years, an amount of spend per hour | Steady spend where you still want flexibility in what runs |
| Spot | None, capacity can be reclaimed | Fault-tolerant, interruption-tolerant work chasing the deepest discount |
The distinction questions actually probe: Reserved commits to a configuration, Savings Plans commit to spend, and Spot's discount exists because AWS can take the capacity back. A workload described as "cannot tolerate interruption" eliminates Spot no matter how attractive the price sounds.
Every cost-tool question hides a verb, and each verb maps to exactly one tool:
Swapping Budgets and Cost Explorer is the classic distractor pattern: Budgets looks forward and alerts, Cost Explorer looks backward and explains.
The exam guide puts AWS support plans and resources in Domain 4's scope. The pattern questions use: describe a need, ask for the cheapest plan that meets it.
The give-away signals: "production workload" points at Business or above, and any mention of a Technical Account Manager points at Enterprise.
Because the depth is identify-the-right-thing, the highest-yield rehearsal is mapping scenario phrases to answers: "estimate the monthly cost of a planned workload" is the Pricing Calculator, "notify the team when spend exceeds $500" is Budgets, "which service drove last month's increase" is Cost Explorer, "single bill across 40 accounts" is consolidated billing, "commit for a discount but keep flexibility" is a Savings Plan, and "batch jobs that can be interrupted, at lowest cost" is Spot. If those six connections are automatic, Domain 4 is close to solved.
Domain 4 of CLF-C02 covers the pricing models (On-Demand, Reserved, Spot, Savings Plans), the cost management tools (AWS Budgets, Cost Explorer, the AWS Pricing Calculator), consolidated billing through AWS Organizations, and the AWS support plans. It is 12% of scored content, roughly six of the 50 scored questions.
Both trade a 1 or 3 year commitment for a discount, but Reserved commits to a specific instance configuration while Savings Plans commit to an amount of spend per hour and stay flexible about what runs. Scenarios that stress flexibility point at Savings Plans; a fixed, predictable configuration points at Reserved.
Budgets looks forward: you set a threshold and it alerts when actual or forecasted spend crosses it. Cost Explorer looks backward: it visualizes and breaks down what you have already spent. "Notify" or "alert" in a question points at Budgets; "analyze" or "identify what drove costs" points at Cost Explorer.
No. The exam tests pricing concepts, not rate cards: which model fits a described workload, which tool answers a cost question, and which support plan meets a need. No question asks for a dollar figure from memory.
The CLF-C02 exam guide lists Domain 4's task statements and in-scope tools. It is a short read, and questions are written directly from it.
