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 uses AWS Organizations with multiple accounts. The security team wants to centrally collect and analyze VPC Flow Logs from all accounts. What is the MOST efficient way to achieve this?
Use AWS Firewall Manager to deploy VPC Flow Logs and aggregate logs in a single account.
Why wrong: Firewall Manager does not aggregate VPC Flow Logs.
B
Configure VPC Flow Logs to deliver to a central CloudWatch Logs log group in the management account.
Why wrong: CloudWatch Logs cross-account requires subscription filters and is not native.
C
Configure VPC Flow Logs to deliver to a central S3 bucket in the security account, and use a bucket policy that grants the source accounts permission to write.
VPC Flow Logs can deliver directly to S3 cross-account using a bucket policy.
D
Set up VPC Flow Logs in each account to deliver to local S3 buckets, then use S3 replication to copy to a central bucket.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure VPC Flow Logs to deliver to a central S3 bucket in the security account, and use a bucket policy that grants the source accounts permission to write.
Option C is correct because it uses a central S3 bucket in the security account with a bucket policy that grants the PutObject permission to the VPC Flow Logs delivery service from each source account. This is the most efficient approach as it avoids per-account configuration overhead, eliminates the need for cross-account replication, and provides a single location for centralized analysis using services like Amazon Athena or Amazon QuickSight.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Replication adds complexity and cost.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume Firewall Manager (Option A) handles log aggregation, but it only manages the configuration policy, not the actual log delivery destination; similarly, many mistakenly think CloudWatch Logs (Option B) supports cross-account delivery natively, which it does not.
Detailed technical explanation
How to think about this question
VPC Flow Logs can deliver directly to an S3 bucket in a different account by using a bucket policy that allows the `s3:PutObject` action from the source account's VPC Flow Logs service principal (e.g., `delivery.logs.amazonaws.com`). This leverages the AWS global infrastructure to write logs in near real-time without additional services. In practice, this setup is often combined with S3 Event Notifications to trigger a Lambda function for parsing or enrichment, enabling scalable threat detection across hundreds of accounts.
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.
