- A
Use AWS Organizations to enable VPC Flow Logs in all accounts and deliver to a central S3 bucket.
Organizations allows you to deploy flow log configurations across accounts using StackSets.
- B
Create a single VPC Flow Log subscription in the security account that captures logs from all VPCs.
Why wrong: VPC Flow Logs must be configured per VPC; a single subscription cannot capture logs from other accounts.
- C
Use Amazon Kinesis Data Firehose to deliver flow logs to the central S3 bucket.
Kinesis Firehose can ingest flow logs and deliver to S3 with near-real-time latency.
- D
Create a CloudWatch Logs subscription filter in each account to stream logs to the security account.
Why wrong: This adds overhead and requires managing subscriptions per account.
- E
Configure S3 replication from each account's bucket to the central bucket.
Why wrong: Replication is not real-time and adds additional costs.
Quick Answer
The answer is to use AWS Organizations for central management and Amazon Kinesis Data Firehose for delivery to the central S3 bucket. AWS Organizations enables you to centrally configure VPC Flow Logs across all accounts in the organization using a single policy, eliminating the need to manually set up flow logs per account. Kinesis Data Firehose then streams those logs directly to the central S3 bucket in the security account, and because it integrates with Kinesis Data Analytics, you can perform real-time analysis on the flow data without additional infrastructure. On the SCS-C02 exam, this scenario tests your understanding of cross-account logging architectures and the trade-offs between streaming services; a common trap is choosing CloudWatch Logs subscription filters, which add latency and overhead for real-time needs, or S3 replication, which is batch-based and not real-time. Remember the mnemonic “Org for control, Firehose for flow” to recall that centralized management requires Organizations, while real-time streaming to S3 demands Kinesis Firehose.
SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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 is designing a centralized logging solution for VPC Flow Logs across multiple AWS accounts. The solution must meet the following requirements: - Centralized storage in an S3 bucket in the security account. - Real-time analysis of flow logs. - Minimal operational overhead. Which TWO actions should the company take? (Choose two.)
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
Use AWS Organizations to enable VPC Flow Logs in all accounts and deliver to a central S3 bucket.
Option A is correct because AWS Organizations allows you to centrally manage flow log subscriptions. Option C is correct because Amazon Kinesis Data Firehose can stream flow logs to S3 and enable real-time analysis via Kinesis Analytics. Option B is wrong because CloudWatch Logs subscription filter is not the most efficient for real-time analysis. Option D is wrong because S3 replication adds complexity and is not real-time. Option E is wrong because cross-account flow logs cannot be delivered directly via a single subscription from the security account; each account must create its own flow log.
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.
