Question 76 of 100 | ← Chapter 1

An online retail company has an application that runs on Amazon EC2 instances that are in a VPC. The company wants to collect flow logs for the VPC and analyze network traffic. Which solution will meet these requirements MOST cost-effectively?

• A. Publish flow logs to Amazon CloudWatch Logs. Use Amazon Athena for analytics.
• B. Publish flow logs to Amazon CloudWatch Logs. Use an Amazon OpenSearch Service cluster for analytics.
• C. Publish flow logs to Amazon S3 in text format. Use Amazon Athena for analytics.
• D. Publish flow logs to Amazon S3 in Apache Parquet format. Use Amazon Athena for analytics. ✓

Correct Answer: D. Publish flow logs to Amazon S3 in Apache Parquet format. Use Amazon Athena for analytics.

Explanation

答案D是最经济有效的方案。将流日志发布到AmazonS3并采用ApacheParquet格式，能够高效地存储和处理大量数据。AmazonAthena可以直接对存储在S3中的Parquet格式数据进行查询和分析，这种组合在成本和性能方面具有优势。相比之下，选项A和B中使用CloudWatchLogs可能会产生较高的存储成本。选项C中以文本格式存储在S3不如Parquet格式高效。所以，选择选项D。
