The answer is to create an organization trail in the management account that logs all accounts. This is correct because AWS Organizations enables a single CloudTrail configuration in the management account to automatically apply to every member account, delivering all API calls to a centralized S3 bucket in the security account without any per-account setup. The S3 bucket policy must also grant CloudTrail write access from all accounts in the organization. On the AWS Certified Security Specialty SCS-C02 exam, this concept tests your understanding of centralized governance versus manual per-account logging, and a common trap is attempting to configure individual trails in each member account instead of leveraging the organization trail. Remember the memory tip: “One trail to rule them all” — the management account’s organization trail is the single source of truth for centralized CloudTrail logging across a multi-account strategy.
SCS-C02 Threat Detection and Incident Response Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident response. 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 has a multi-account strategy and wants to ensure that all API calls from member accounts are logged to a centralized S3 bucket in the security account. Which configuration is required?
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 logs all accounts
Option B is correct because AWS Organizations allows you to create an organization trail in the management account that automatically applies to all member accounts. This ensures that CloudTrail logs from every account in the organization are delivered to a single, centralized S3 bucket in the security account without needing per-account configuration. The organization trail uses the management account’s CloudTrail configuration to enable logging across the entire organization, and the S3 bucket policy must grant the necessary permissions for CloudTrail to write logs from all accounts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use Amazon Kinesis Data Streams to stream CloudTrail events from all accounts to the central S3 bucket
Why it's wrong here
CloudTrail does not stream to S3 via Kinesis; it delivers directly.
✓
Create an organization trail in the management account that logs all accounts
Why this is correct
Organization trail logs all accounts and delivers to a single S3 bucket.

Read the scenario before looking for a memorised answer.
✗
Create a CloudTrail trail in each member account and specify the same S3 bucket
Why it's wrong here
This is possible but not centralized management; each account must be configured separately.
✗
Enable AWS Security Hub in the security account and configure it to collect CloudTrail logs
Why it's wrong here
Security Hub aggregates findings, not raw CloudTrail logs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume creating separate trails per account (Option C) is simpler or more reliable, but they overlook the AWS Organizations integration that allows a single organization trail to automatically cover all accounts, reducing administrative overhead and ensuring consistent log delivery.
Detailed technical explanation
How to think about this question
An organization trail in CloudTrail uses the management account’s trail configuration to enable logging for all accounts in the AWS Organization, including future accounts added to the organization. The S3 bucket policy must include a condition that allows the CloudTrail service principal (cloudtrail.amazonaws.com) to write objects from any account in the organization, typically using the `aws:SourceOrgID` condition key to restrict access to the specific organization ID. This setup ensures that logs are delivered with a consistent prefix structure (e.g., `AWSLogs/<account-id>/CloudTrail/`) and simplifies auditing by eliminating per-account trail management.

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.
