Question

A financial company wants to use Amazon Athena to run on-demand SQL queries on a petabyte-scale dataset to support a business intelligence (BI) application. An AWS Glue job that runs during non-business hours updates the dataset once every day. The BI application has a standard data refresh frequency of 1 hour to comply with company policies. A data engineer wants to cost optimize the company's use of Amazon Athena without adding any additional infrastructure costs. Which solution will meet these requirements with the LEAST operational overhead?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Use the query result reuse feature of Amazon Athena for the SQL queries. Amazon Athena runs serverless SQL queries directly on data in Amazon S3 with no infrastructure to manage.
