- A
Manually disable CloudTrail in each member account.
Why wrong: Manual process is not scalable and may miss accounts.
- B
Create an organization trail in the management account that applies to all accounts.
Organization trails automatically apply to all accounts in the organization.
- C
Use AWS Config rules to detect non-compliant trails and trigger automatic remediation.
Why wrong: Config can detect but does not prevent creation; SCP is preventive.
- D
Enable CloudTrail on the centralized S3 bucket to log access.
Server access logging is not required, but the bucket should have proper permissions.
- E
Use a service control policy (SCP) to deny the 'cloudtrail:CreateTrail' and 'cloudtrail:UpdateTrail' actions.
SCP prevents member accounts from creating their own trails.
Quick Answer
The correct answer involves three steps: creating an organization trail in the management account, enabling CloudTrail on the centralized S3 bucket, and using a service control policy (SCP) to deny the cloudtrail:CreateTrail and cloudtrail:UpdateTrail actions. This combination works because an organization trail automatically applies to all accounts in AWS Organizations, delivering logs to the specified bucket, while the SCP prevents member accounts from creating or modifying their own trails, thereby enforcing organization-wide CloudTrail trails. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of preventive versus detective controls—SCPs are preventive, whereas AWS Config rules (a common trap) can only detect non-compliance, not block it. A key memory tip is “SCP to stop, Org trail to drop”: the SCP stops rogue trails, and the organization trail drops logs into the central bucket.
DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. 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 with multiple accounts. The security team needs to ensure that all CloudTrail trails across the organization are delivering events to a centralized S3 bucket in the management account. Currently, some member accounts have their own trails. Which THREE steps should the security team take to enforce this? (Choose three.)
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 organization trail in the management account that applies to all accounts.
Option A is correct because creating an organization trail in the management account will automatically apply to all accounts. Option B is correct because enabling CloudTrail on the S3 bucket ensures logs are delivered. Option D is correct because SCP can deny the ability to create or modify trails, preventing member accounts from creating separate trails. Option C is wrong because disabling CloudTrail in member accounts is manual and not scalable. Option E is wrong because Config rules can detect but not prevent.
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.

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 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 DOP-C02 ACL questions on filtering logic and placement.

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 a multi-account strategy using AWS Organizations. The security team needs to respond to incidents across all accounts. They want to ensure that all CloudTrail trails are enabled and logging to a central S3 bucket in the management account. What is the MOST efficient way to monitor compliance?
hard- A.Create a CloudTrail organization trail and use CloudTrail Insights to detect configuration changes.
- ✓ B.Use AWS Config conformance packs with a managed rule to check CloudTrail is enabled.
- C.Set up CloudWatch Events rules in each account to detect trail disabling.
- D.Use AWS Trusted Advisor to check CloudTrail configuration in each account.
Why B: Option D is correct because AWS Config conformance packs can evaluate whether CloudTrail trails are enabled across accounts using managed rules. Option A is wrong because Trusted Advisor does not monitor CloudTrail configuration across all accounts. Option B is wrong because CloudTrail itself does not monitor trail configuration. Option C is wrong because CloudWatch Events can be used but require custom rules per account; Config is more efficient.
