The answer is to use AWS Organizations to create a CloudTrail trail that applies to all accounts. This is correct because AWS Organizations enables you to define a single organization trail that automatically logs management and data events from every member account into a centralized S3 bucket, eliminating the need for per-account manual configuration. On the AWS Certified Security Specialty SCS-C02 exam, this concept tests your understanding of centralized logging architectures and the distinction between an organization trail and individual account trails. A common trap is selecting services like AWS Config or Amazon Detective, which are for compliance and investigation, not log collection. Remember the key phrase: “one trail to rule them all” — if you see a requirement to centralize CloudTrail logs across multiple accounts, immediately think of AWS Organizations as the enabler for that single, organization-wide trail.
SCS-C02 Security Logging and Monitoring Practice Question
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 engineer needs to centrally collect and analyze AWS CloudTrail logs from multiple accounts. Which service is designed for this purpose?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Organizations to create a CloudTrail trail that applies to all accounts
Option D is correct because AWS Organizations allows you to create a single CloudTrail trail that applies to all accounts in the organization, centrally collecting management and data events into a single S3 bucket (and optionally CloudWatch Logs). This eliminates the need to manually configure trails in each account and ensures consistent logging across the entire organization, meeting the requirement for central collection and analysis.
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.
✗
Configure each account to send logs to a central S3 bucket
Why it's wrong here
This is possible but not the designed service; it's manual.
✗
Enable Amazon GuardDuty in each account and aggregate findings
Why it's wrong here
GuardDuty is for threat detection, not log collection.
✗
Use Amazon CloudWatch Logs to stream logs from each account to a central account
Why it's wrong here
Possible but CloudWatch is not the primary solution.
✓
Use AWS Organizations to create a CloudTrail trail that applies to all accounts
Why this is correct
Organizations allows a single trail to log all accounts.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'centralized logging' with simply sending logs to a central S3 bucket (Option A), missing the key requirement that AWS Organizations provides a single, managed trail that applies to all accounts automatically, rather than requiring per-account configuration.
Detailed technical explanation
How to think about this question
Under the hood, when you create a CloudTrail trail with AWS Organizations, CloudTrail automatically creates a service-linked role (AWSServiceRoleForCloudTrail) in each member account to enable log delivery to the central S3 bucket. The trail's S3 bucket policy must grant cross-account permissions for all organization accounts, and CloudTrail uses the organization ID to validate that logs originate from member accounts. A real-world scenario is when an organization has hundreds of accounts; using Organizations ensures that new accounts added to the organization automatically start logging to the central trail without manual intervention.

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.
