AWS Certified Data Engineer – Associate (DEA-C01) — Question 46

A data engineer needs to maintain a central metadata repository that users access through Amazon EMR and Amazon Athena queries. The repository needs to provide the schema and properties of many tables. Some of the metadata is stored in Apache Hive. The data engineer needs to import the metadata from Hive into the central metadata repository.
Which solution will meet these requirements with the LEAST development effort?

Answer options

• A. Use Amazon EMR and Apache Ranger.
• B. Use a Hive metastore on an EMR cluster.
• C. Use the AWS Glue Data Catalog.
• D. Use a metastore on an Amazon RDS for MySQL DB instance.

Correct answer: C

Explanation

The AWS Glue Data Catalog is designed to serve as a central repository for metadata, making it the best choice for this scenario with minimal development effort. Options A and B are less efficient as they involve additional configurations and setups, while option D requires managing a separate RDS instance, which complicates the architecture.
