CLF-C02 Domain 4 - Billing Pricing and Support
Domain 4 is 12% of the scored AWS Certified Cloud Practitioner (CLF-C02) exam. It tests purchasing models, cost tools, consolidated billing, and how to find the right AWS support resource.
4.1 Pricing models
- On-Demand: no long commitment; best for uncertain or short-lived workloads.
- Savings Plans: commit to a consistent USD/hour amount for one or three years; Compute Savings Plans are more flexible than EC2 Instance Savings Plans.
- Reserved Instances: billing discount/reservation model for eligible services; Standard is less flexible and can discount more than Convertible.
- Spot Instances: spare EC2 capacity at deep discounts, but interruptible; use for fault-tolerant workloads.
- Dedicated Hosts vs Dedicated Instances: physical-server visibility/licensing control vs instances isolated on single-tenant hardware without host-level placement control.
- Capacity Reservations: reserve EC2 capacity in an AZ; they do not inherently provide the billing discount of Savings Plans or RIs.
- Data transfer in is commonly free, while transfer out and cross-Region traffic commonly cost money; always check the service/Region pricing page.
4.2 Billing and cost management
- AWS Pricing Calculator estimates a planned architecture before deployment.
- AWS Cost Explorer analyzes historical/current spend and forecasts; AWS Budgets sets thresholds and alerts; AWS Cost and Usage Report provides the most detailed line-item export.
- AWS Organizations consolidated billing combines member-account charges and can share eligible volume discounts, RIs, and Savings Plans according to configuration.
- Cost allocation tags group costs by owner, project, environment, or other business dimension after activation.
- AWS Cost Anomaly Detection identifies unusual spend; AWS Compute Optimizer recommends rightsizing based on utilization.
AWS Free Tier in 2026
For accounts created on or after July 15, 2025, new customers receive 100 more. They choose a six-month Free plan with restricted service access/no surprise charges or a Paid plan with full service access and pay-as-you-go charges beyond credits. More than 30 always-free offers remain. Legacy accounts/offers can still have older 12-month or trial rules, so do not treat “12 months” as the universal current model.
4.3 Support and technical resources
- Current standard plans are Basic, Business Support+, Enterprise Support, and AWS Unified Operations. Developer, plain Business, and Enterprise On-Ramp are transition plans scheduled to end January 1, 2027 (except stated GovCloud exceptions).
- Basic covers account/billing help, forums, health checks, and documentation. Business Support+ adds 24/7 engineers, AI assistance, a sub-30-minute business-critical response target, full Trusted Advisor, and third-party software support.
- Enterprise adds a designated TAM, up-to-15-minute production-critical response, Security Incident Response, and strategic reviews. Unified Operations adds deeper proactive specialists/monitoring and a five-minute context-aware critical-incident response for onboarded workloads.
- AWS Support and AWS Support Plans explain plan selection; AWS Trusted Advisor gives best-practice checks; AWS Health Dashboard shows public/account-specific events.
- Use AWS Documentation, AWS Knowledge Center, AWS re:Post, AWS Prescriptive Guidance, AWS Security Blog, AWS Partners, AWS Professional Services, and solutions architects according to the question.
Common traps
- Pricing Calculator predicts; Cost Explorer analyzes; Budgets alerts; Cost and Usage Reports export detail.
- A Savings Plan is a spend commitment, not an EC2 capacity reservation.
- The exam guide still gives older support-plan examples, but 2026 product questions should use the current plan names and transition note above.
