SCS-C02 Management and Security Governance Practice Question

This SCS-C02 practice question tests your understanding of management and security governance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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's Security team is using AWS Organizations with a consolidated billing account. The security team wants to ensure that all member accounts have AWS CloudTrail enabled and that logs are delivered to a central S3 bucket in the management account. Which combination of actions should the security team take? (Choose the best answer.)

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.

A
Use AWS Config rules to detect when CloudTrail is disabled.
Why wrong: Config rules only detect, not prevent.
B
Create a new IAM policy that requires each account owner to enable CloudTrail.
Why wrong: This is not enforced automatically.
C
Enable CloudTrail in the management account only and use cross-account logging.
Why wrong: Does not cover member accounts.
D
Use an SCP to deny disabling CloudTrail and use CloudFormation StackSets to deploy CloudTrail in all accounts.
SCP prevents disabling, StackSets deploy automatically.

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

✓

Use an SCP to deny disabling CloudTrail and use CloudFormation StackSets to deploy CloudTrail in all accounts.

Option D is correct because using an SCP to deny disabling CloudTrail and a CloudFormation StackSet to deploy CloudTrail in each account ensures enforcement and deployment across all member accounts. Option A is wrong because AWS Config rules can detect but not prevent disabling of CloudTrail. Option B is wrong because an IAM policy requiring account owners to enable CloudTrail is not enforceable and relies on individual action. Option C is wrong because enabling CloudTrail only in the management account does not enable it in member accounts; cross-account logging requires member accounts to have CloudTrail configured.

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.

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 SCS-C02 ACL questions on filtering logic and placement.
