- A
Amazon CloudWatch Logs
Why wrong: CloudWatch Logs can aggregate logs but requires additional setup like Kinesis or Lambda for cross-account; S3 is simpler and recommended.
- B
AWS CloudTrail (Organization Trail)
Organization Trail collects CloudTrail logs from all accounts into a single S3 bucket.
- C
AWS Config
Why wrong: AWS Config records resource configuration changes, not logs.
- D
Amazon GuardDuty
Why wrong: GuardDuty generates findings, not logs.
- E
Amazon S3
S3 can serve as a central repository for VPC Flow Logs and DNS logs from multiple accounts.
Question 1,375 of 1,748
How to Centralize CloudTrail, VPC Flow Logs, and DNS Logs Across Accounts
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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 security team is designing a logging solution for a multi-account AWS environment using AWS Organizations. They need to collect CloudTrail logs, VPC Flow Logs, and DNS logs from all accounts. Which TWO services can be used to centralize this logging?
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
✓
AWS CloudTrail (Organization Trail)
AWS CloudTrail Organization Trail is the correct choice because it automatically creates a single logging account (the management account or a delegated administrator) that receives CloudTrail logs from all member accounts in the AWS Organization. This eliminates the need to manually configure trails in each account and ensures centralized, immutable log collection for management events across the entire multi-account environment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Amazon CloudWatch Logs as a centralization service for multi-account logging, but it requires additional infrastructure (e.g., cross-account subscription filters or Kinesis Data Firehose) to aggregate logs from multiple accounts, whereas S3 is the native, scalable destination for centralized log storage across an Organization.
Detailed technical explanation
How to think about this question
An Organization Trail in CloudTrail can be configured to deliver logs to a single S3 bucket in the management account (or a delegated administrator account), with optional SSE-KMS encryption and log file validation. VPC Flow Logs and DNS logs (e.g., from Route 53 Resolver query logs) can be published to the same centralized S3 bucket using cross-account delivery or by aggregating them via AWS Firewall Manager or AWS Config rules, but the question asks for services that can centralize all three log types—S3 is the common destination, while CloudTrail handles the CloudTrail-specific logs. Under the hood, CloudTrail uses a service-linked role to create trails in each member account, and the Organization Trail API (CreateTrail with IsOrganizationTrail=true) automatically replicates the trail configuration across all accounts, ensuring no gaps in coverage.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
