Question 523 of 988
CLF-C02 Billing, Pricing, and Support Practice Question
A company has multiple AWS accounts that are consolidated under AWS Organizations. The finance team receives a single monthly bill for all accounts. The team needs to allocate costs to individual departments based on which department owns each resource. They want to see a breakdown of costs by department in the monthly cost report without manually combining data from each account. Which action should the finance team take to meet these requirements?
⚠ Common exam trap
Many candidates confuse AWS Budgets (which only tracks spending against thresholds) with cost allocation tags and Cost Explorer (which provide actual cost breakdowns), or assume that separate accounts or payment methods are necessary for cost allocation when tags suffice.
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
✓
Activate cost allocation tags, tag all resources with a department identifier, and use Cost Explorer to filter and group costs by the tag.
Activating cost allocation tags and tagging all resources with a department identifier allows the finance team to use Cost Explorer to filter and group costs by that tag. This provides a per-department cost breakdown in the consolidated monthly bill without manual aggregation, leveraging AWS Organizations' consolidated billing and tag-based cost tracking.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Activate cost allocation tags, tag all resources with a department identifier, and use Cost Explorer to filter and group costs by the tag.
Why this is correct
Correct. Cost allocation tags allow you to categorize and track AWS costs by department. After activating the tags in the Billing console, Cost Explorer can display cost breakdowns by tag value, enabling department-level cost allocation without manual work.
- ✗
Set up separate payment methods for each department's AWS account so that each department receives its own bill.
Why it's wrong here
Incorrect. AWS Organizations does not support using different payment methods for member accounts; the payer account is billed for all member accounts. This approach violates consolidated billing and would not produce a per-department breakdown from a single payer.
When this WOULD be correct
This option would be correct if the requirement was to have each department receive its own independent bill and manage its own payment, rather than consolidating costs under a single payer account for internal cost allocation.
- ✗
Create a dedicated AWS account for each department and manually sum the charges from each account's monthly bill.
Why it's wrong here
Incorrect. While the company already has multiple accounts, manually summing bills is inefficient and error-prone. AWS provides automated tools like cost allocation tags and Cost Explorer to break down costs by tag, which is the recommended approach.
When this WOULD be correct
If the requirement was to isolate costs by department with separate billing and no need for consolidated reporting, and the company did not use AWS Organizations or cost allocation tags, then creating separate accounts and manually summing could be a fallback.
- ✗
Use AWS Budgets to set a spending threshold for each department and review the alerts to estimate departmental costs.
Why it's wrong here
Incorrect. AWS Budgets tracks total spending or usage against a budget but does not provide a cost allocation breakdown by tag or dimension. Budget alerts can notify when spending nears a limit, but they don't generate a per-department cost report.
When this WOULD be correct
A company needs to monitor spending per department and receive notifications when costs exceed predefined limits, but does not require detailed cost allocation or a breakdown in the monthly report. In that scenario, AWS Budgets with department-specific budgets and alerts would be the correct solution.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓Activate cost allocation tags, tag all resources with a department identifier, and use Cost Explorer to filter and group costs by the tag.Correct answer▾
Why this is correct
Correct. Cost allocation tags allow you to categorize and track AWS costs by department. After activating the tags in the Billing console, Cost Explorer can display cost breakdowns by tag value, enabling department-level cost allocation without manual work.
✗Set up separate payment methods for each department's AWS account so that each department receives its own bill.Wrong answer — click to see why▾
Why this is wrong here
Setting up separate payment methods does not provide a consolidated view of costs by department within a single monthly bill; it creates separate bills, which contradicts the requirement to see a breakdown in the monthly cost report without manual combination.
★ When this WOULD be the correct answer
This option would be correct if the requirement was to have each department receive its own independent bill and manage its own payment, rather than consolidating costs under a single payer account for internal cost allocation.
Why candidates choose this
Candidates may think that separate payment methods naturally segregate costs by department, overlooking that the requirement is for a consolidated report with cost allocation tags, not separate billing.
✗Create a dedicated AWS account for each department and manually sum the charges from each account's monthly bill.Wrong answer — click to see why▾
Why this is wrong here
Manually summing charges from each account's monthly bill is not automated and does not scale, failing the requirement to avoid manual work.
★ When this WOULD be the correct answer
If the requirement was to isolate costs by department with separate billing and no need for consolidated reporting, and the company did not use AWS Organizations or cost allocation tags, then creating separate accounts and manually summing could be a fallback.
Why candidates choose this
Candidates may think that separate accounts inherently provide cost separation, overlooking the manual effort required to aggregate data across accounts.
✗Use AWS Budgets to set a spending threshold for each department and review the alerts to estimate departmental costs.Wrong answer — click to see why▾
Why this is wrong here
AWS Budgets provides alerts on spending thresholds but does not generate a breakdown of costs by department in the monthly cost report; it lacks the granular tagging and grouping capabilities needed for departmental cost allocation.
★ When this WOULD be the correct answer
A company needs to monitor spending per department and receive notifications when costs exceed predefined limits, but does not require detailed cost allocation or a breakdown in the monthly report. In that scenario, AWS Budgets with department-specific budgets and alerts would be the correct solution.
Why candidates choose this
Candidates may think that setting budgets for each department and reviewing alerts can provide cost estimates, but they overlook that budgets do not produce a structured cost breakdown or replace the need for tagging and Cost Explorer analysis.
