SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. 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 is using AWS Organizations with consolidated billing. They want to track costs by department, where each department has its own AWS account. Which service should they use to tag resources with department IDs and view cost breakdowns?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Cost Explorer with cost allocation tags.
Cost allocation tags in AWS allow you to tag resources (e.g., EC2 instances, S3 buckets) with department IDs and then use AWS Cost Explorer to view cost breakdowns by those tags. This directly meets the requirement to track costs per department account within AWS Organizations with consolidated billing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 Budgets with tag-based filters.
Why it's wrong here
Budgets can use tags, but the primary purpose is budgeting, not detailed cost reporting.
✗
AWS Trusted Advisor cost optimization checks.
Why it's wrong here
Trusted Advisor provides recommendations, not cost breakdowns by tag.
✗
AWS Cost Explorer with tag-based filtering.
Why it's wrong here
Cost Explorer can filter by tags, but it does not enforce tagging; tags must be applied manually or via other means.
✓
AWS Cost Explorer with cost allocation tags.
Why this is correct
Cost allocation tags (user-defined) can be applied to resources and used in Cost Explorer to break down costs by department.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing 'tag-based filtering' (which is not a native Cost Explorer feature) with 'cost allocation tags' (the correct mechanism), leading candidates to pick Option C instead of D.
Detailed technical explanation
How to think about this question
Cost allocation tags must be activated in the Billing and Cost Management console before they appear in Cost Explorer; only activated tags are propagated to the cost and usage reports. Under the hood, AWS generates a cost allocation report that maps resource usage to tag keys, enabling per-department cost aggregation even across multiple accounts in an organization.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
