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
✓
Amazon S3 and Amazon Athena
VPC Flow Logs from each account's VPCs can be published to a centralized Amazon S3 bucket using cross-account permissions. Amazon Athena can then be used to query and analyze the flow logs directly from S3 using standard SQL. This approach provides a cost-effective and scalable solution for centralizing network logging across multiple accounts. Option A is incorrect because AWS CloudTrail logs API activity, not network traffic; CloudWatch Logs can aggregate logs but require additional subscription filters for cross-account. Option B is incorrect because Kinesis Data Streams is designed for real-time streaming and requires additional processing to store and analyze logs, making it less suitable for historical analysis. Option D is incorrect because AWS Config records configuration changes and resource compliance, not network traffic logs.
