Exam AWS Certified Data Engineer - Associate DEA-C01 topic 1 question 45 discussion

https://docs.aws.amazon.com/athena/latest/ug/notebooks-spark-getting-started.html "To use Apache Spark in Amazon Athena, you create an Amazon Athena workgroup that uses a Spark engine."

The Athena data source acts as a bridge between Athena and other analytics engines, such as Apache Spark. By using the Athena data source connector, you can access data stored in various formats (e.g., CSV, JSON, Parquet) and locations (e.g., Amazon S3, Apache Hive Metastore) through Spark applications

B makes sense

It is B, not C. The workgroup is for organizing, controlling, and monitoring queries. The Data source is the mechanism that enables Spark to query data via Athena. It allows Spark to interact with Athena. The question focuses on enabling Apache Spark within Athena to generate analytics instead of using SQL. Thus, you must create a Spark-enabled workgroup

Athena datasource doesn't specifially enable Spark access

https://docs.aws.amazon.com/athena/latest/ug/notebooks-spark-getting-started.html To get started with Apache Spark on Amazon Athena, you must first create a Spark enabled workgroup. After you switch to the workgroup, you can create a notebook or open an existing notebook. When you open a notebook in Athena, a new session is started for it automatically and you can work with it directly in the Athena notebook editor.

C. Athena data source The Athena data source is a specific connector or library that allows Apache Spark to interact with data stored in Amazon Athena. This connector enables Spark to read data from Athena tables directly into Spark DataFrames or RDDs (Resilient Distributed Datasets), allowing you to perform analytics and transformations using Spark's capabilities.

B is the correct answer. https://aws.amazon.com/blogs/big-data/explore-your-data-lake-using-amazon-athena-for-apache-spark/ You need an Athena workgroup as a prerequisite to use Apache Spark.

B. is the correct answer. To use Apache Spark in Amazon Athena, you create an Amazon Athena workgroup that uses a Spark engine. https://docs.aws.amazon.com/athena/latest/ug/notebooks-spark-getting-started.html
