1. Right Answer: D
Explanation: Amazon Athena is defined as 'an interactive query service that makes it easy to analyse data directly inAmazon Simple Storage Service (Amazon S3) using standard SQL. So, it's another SQL query engine forlarge data sets stored in S3. This is very similar to other SQL query engines, such as Apache Drill. But unlikeApache Drill, Athena is limited to data only from Amazon's own S3 storage service. However, Athena is able toquery a variety of file formats, including, but not limited to CSV, Parquet, JSON, etc
2. Right Answer: A
Explanation: AWS CloudFormation provides a common language for you to model and provision AWS and third partyapplication resources in your cloud environment.
