- A
Create an AWS Config aggregator in the management account and enable Config for each account manually.
Why wrong: Manual configuration is inefficient and error-prone.
- B
Use AWS CloudFormation StackSets to deploy a Config template to each account, and manually add new accounts to the StackSet.
Why wrong: Manual addition of accounts is required.
- C
Use AWS Lambda functions triggered by AWS CloudTrail to enable Config and deploy rules whenever a new account is created.
Why wrong: Lambda approach can be complex and may not cover all scenarios.
- D
Create an SCP to deny disabling AWS Config, and use an AWS Config conformance pack in a delegated admin account to enforce rules across the organization.
SCP enforces Config enablement; conformance pack enforces rules automatically on new accounts.
Quick Answer
The answer is to create an SCP that denies disabling AWS Config and deploy an AWS Config conformance pack from a delegated admin account. This solution is the most efficient because the SCP acts as a preventive guardrail at the root organizational unit, ensuring Config cannot be turned off in any new member account, while the conformance pack automatically enforces the required set of rules across the entire organization without per-account manual setup. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of combining service control policies for mandatory security baselines with delegated administration for scalable governance—a common trap is choosing CloudFormation StackSets, which require manual stack instance updates for new accounts, or relying on event-driven Lambda functions that introduce latency and gaps. Remember the memory tip: “SCP to lock, conformance pack to stock”—the SCP locks Config on, and the conformance pack stocks the rules automatically.
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 has multiple AWS accounts managed through AWS Organizations. The security team wants to enforce that all new member accounts automatically have AWS Config enabled with a specific set of rules. Which solution is the MOST efficient?
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
Create an SCP to deny disabling AWS Config, and use an AWS Config conformance pack in a delegated admin account to enforce rules across the organization.
Option C is correct because using an SCP in the root OU to prevent disabling Config, combined with AWS Config conformance packs in a delegation admin account, ensures accounts are created with Config enabled and rules enforced without manual intervention. Option A is wrong because it requires manual setup per account. Option B is wrong because CloudFormation StackSets require manual stack instance updates. Option D is wrong because Lambda functions triggered by account creation can be delayed and may not cover all cases.
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.

Why it's wrong here
Manual addition of accounts is required.
- ✗
Use AWS Lambda functions triggered by AWS CloudTrail to enable Config and deploy rules whenever a new account is created.
Why it's wrong here

Why this is correct
SCP enforces Config enablement; conformance pack enforces rules automatically on new accounts.
Related concept
Standard ACLs match source addresses.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. 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. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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.

Same concept, more angles
1 more ways this is tested on SAP-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company has multiple AWS accounts managed using AWS Organizations. The security team wants to enforce that all new accounts automatically have a specific AWS Config rule enabled to prohibit public S3 bucket access. Which solution requires the least operational overhead?
medium- A.Use AWS CloudFormation StackSets to deploy the AWS Config rule to all accounts.
- B.Enable AWS Config in the management account and use an aggregator for all accounts.
- C.Use an SCP to automatically enable the AWS Config rule in all accounts.
- ✓ D.Use an SCP to deny the s3:PutBucketPublicAccessBlock action if a specific tag is not present.
Why D: Option D is correct because it uses a service control policy (SCP) to deny the s3:PutBucketPublicAccessBlock action unless a specific tag is present. This enforces the desired AWS Config rule indirectly by preventing any action that would disable or bypass the public access block, and it applies automatically to all new accounts in the organization with minimal overhead—no per-account deployment or configuration is needed.
