SCS-C02 Management and Security Governance Practice Question
This SCS-C02 practice question tests your understanding of management and security governance. 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 uses AWS Organizations to manage multiple accounts. The security team wants to ensure that all accounts have AWS CloudTrail enabled and that logs are delivered to a central S3 bucket in the management account. What is the most efficient way to enforce this across all accounts?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a service control policy (SCP) that denies modifications to CloudTrail settings.
Using an SCP in AWS Organizations can deny the action of disabling CloudTrail or modifying trail settings, enforcing that CloudTrail remains enabled. Option A is wrong because it requires manual setup in each account. Option B is wrong because AWS Config can detect but not prevent disabling. Option D is wrong because it only monitors, not enforces.
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.
✓
Create a service control policy (SCP) that denies modifications to CloudTrail settings.
Why this is correct
SCPs can prevent disabling CloudTrail or altering trail configurations across all accounts.
Related concept
Standard ACLs match source addresses.
✗
Use AWS Trusted Advisor to check CloudTrail status and send alerts.
Why it's wrong here
Trusted Advisor only checks and alerts, does not enforce.
✗
Configure each account individually with a CloudTrail trail pointing to the central bucket.
Why it's wrong here
Manual per-account setup is not efficient and may be inconsistent.
✗
Use AWS Config rules in each account to detect non-compliant trails.
Why it's wrong here
Config rules detect but do not prevent disabling; they only alert after the fact.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
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.
