SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 uses AWS Organizations with consolidated billing. The finance team needs to track costs by department, which are tagged with 'department' tags. However, some resources are not tagged. The team wants to ensure that all new resources are tagged, and existing untagged resources are identified. What should they do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a service control policy (SCP) to deny resource creation without the 'department' tag, and use AWS Config rules to detect untagged resources.
Option A is correct because SCPs can deny resource creation without required tags, and AWS Config rules can identify untagged resources. Option B is wrong because SCPs cannot enforce tags on existing resources. Option C is wrong because IAM policies cannot be enforced across accounts easily. Option D is wrong because Cost Explorer can filter by tags but does not enforce tagging.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use a service control policy (SCP) to deny resource creation without the 'department' tag, and use AWS Config rules to detect untagged resources.
Use AWS Config rules to enforce tagging on existing resources and automatically tag them.
Why it's wrong here
Config rules cannot automatically tag; they can only detect.
✗
Use AWS Cost Explorer to report on untagged resources.
Why it's wrong here
Cost Explorer can report but does not enforce tagging.
✗
Create an IAM policy that requires tagging for all actions and attach it to all users.
Why it's wrong here
Not all actions support tagging; IAM policies are not account-wide.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SAP-C02 ACL questions on filtering logic and placement.
