CLF-C02 Billing, Pricing, and Support Practice Question
A company uses multiple AWS accounts for different departments. Which AWS feature enables them to receive a single monthly bill and potentially lower rates through combined usage?
⚠ Common exam trap
Many candidates confuse AWS Cost Allocation Tags (which track costs) with Consolidated Billing (which combines costs), or mistakenly think Cost Explorer can consolidate billing, when it only analyzes existing cost data.
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
✓
AWS Consolidated Billing
AWS Consolidated Billing allows organizations to combine usage across multiple AWS accounts into a single monthly bill. This aggregated usage can qualify for volume pricing discounts and lower rates due to combined resource consumption, such as reaching higher tiers of AWS Support or Reserved Instance benefits.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Cost Allocation Tags
Why it's wrong here
Cost Allocation Tags label resources so costs can be split by department in reports; they neither merge invoices nor combine usage for tiered pricing. They are tempting because tagging is correct when one consolidated bill must be broken down per team for internal chargeback.
- ✓
AWS Consolidated Billing
Why this is correct
AWS Consolidated Billing merges usage from every member account within an AWS Organization into one payer account, producing a single monthly invoice. It aggregates consumption across accounts for volume-tier discounts on services such as S3 and data transfer, directly satisfying the stem's combined-usage and single-bill requirements.
- ✗
AWS Cost Explorer
Why it's wrong here
Cost Explorer visualises and forecasts spend per account but does not consolidate billing or aggregate usage for volume discounts. It is tempting because Cost Explorer is the right tool when a single account's historical spend must be analysed and future costs projected.
- ✗
AWS Marketplace
Why it's wrong here
AWS Marketplace is a catalogue for purchasing third-party software and AMIs, not a billing or pricing mechanism. It is tempting because Marketplace subscriptions appear on the AWS invoice, which is the right choice when procuring vendor software that bills through AWS.
