- A
Create an S3 bucket policy that grants permissions to the CloudTrail and AWS Config service principals from all accounts to write logs.
Bucket policy must allow cross-account delivery.
- B
Use AWS Config aggregator to collect configuration data from all accounts into a central account.
Why wrong: Config aggregator collects configuration items, not logs; logs are delivered per account.
- C
Configure CloudTrail in each account to send logs to the central S3 bucket.
CloudTrail supports cross-account delivery.
- D
Create a customer-managed KMS key with a key policy that allows the CloudTrail and AWS Config service principals to use the key for encryption.
KMS key policy must permit the services to use the key across accounts.
- E
Enable VPC Flow Logs in each account and deliver them to a central CloudWatch Logs group.
Why wrong: VPC Flow Logs cannot be delivered across accounts to a central S3 bucket directly; they go to CloudWatch Logs or S3 per account.
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 AWS environment with 50 accounts. They need to implement a centralized logging solution for VPC Flow Logs, CloudTrail, and AWS Config logs. The logs must be stored in a central S3 bucket and encrypted with a customer-managed KMS key. Which THREE steps should be taken to meet these requirements?
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 S3 bucket policy that grants permissions to the CloudTrail and AWS Config service principals from all accounts to write logs.
Option A is correct because the central S3 bucket must allow log delivery from all accounts via bucket policy. Option B is correct because CloudTrail trails can be configured to deliver to a central bucket across accounts. Option D is correct because KMS key policy must grant permissions to the log delivery services across accounts. Option C is wrong because VPC Flow Logs cannot be directly aggregated to a central account without third-party tools or cross-account delivery. Option E is wrong because AWS Config data is per-account; aggregation is done via Aggregator, not direct log delivery.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
