Question 82 of 100 | ← Chapter 1

An insurance company stores transaction data that the company compressed with gzip. The company needs to query the transaction data for occasional audits. Which solution will meet this requirement in the MOST cost-effective way?

• A. Store the data in Amazon Glacier Flexible Retrieval. Use Amazon S3 Glacier Select to query the data. ✓
• B. Store the data in Amazon S3. Use Amazon S3 Select to query the data.
• C. Store the data in Amazon S3. Use Amazon Athena to query the data.
• D. Store the data in Amazon Glacier Instant Retrieval. Use Amazon Athena to query the data.

Correct Answer: A. Store the data in Amazon Glacier Flexible Retrieval. Use Amazon S3 Glacier Select to query the data.

Explanation

答案A是最符合成本效益的选择。GlacierFlexibleRetrieval适用于长期存储且不常访问的数据，成本相对较低。当需要偶尔查询审计时，使用S3GlacierSelect可以直接在压缩数据上进行查询，避免了数据解压和全部取回的高成本操作。相比之下，选项B中单纯将数据存储在S3可能成本较高。选项C中使用Athena查询存储在S3的数据，也存在一定成本且不如选项A针对压缩数据查询的针对性强。选项D中GlacierInstantRetrieval成本较高，不太符合成本效益原则。所以选择A选项。
