Question 61

Which data warehouse service can be used to query data in an Amazon S3 data lake without loading the data?

Amazon RDS

AWS Lambda

Amazon RedShift

Amazon EMR

Answer: 3

Explanation:

Amazon Redshift extends data warehouse queries to your data lake, with no loading required. You can run analytic queries against petabytes of data stored locally in Redshift, and directly against exabytes of data stored in Amazon S3

Amazon RDS is not a data warehouse and cannot query data in S3 at rest

AWS Lambda runs code as functions and is not a data warehouse

Amazon Elastic Map Reduce (EMR) provides a managed Hadoop service and cannot query data in S3 at rest
