Exam AWS Certified Data Engineer - Associate DEA-C01 topic 1 question 4 discussion

The answer is B and E. The data mesh implementation uses Amazon S3 and Athena for data storage and analysis, and AWS Lake Formation for centralized data governance and access control. When combined with AWS Glue, you can efficiently manage your data.

S3 (storage) LakeFormation (governance) Athena (analytics) can be used to implement data mesh. In real life you would use DataZone or nowadays SageMaker Unified Studio

S3 is best storage for data lake, and AWS lake formation is best for management.

BE are correct answer.

Sometimes I think examtopics uses us to calibrate the right answers hehehe, by the goal statement and the services outlines and objectives there are no way the answer be different then B,E

A: Cost-effective storage: Amazon S3 is a highly scalable and cost-effective object storage service perfect for storing large datasets commonly found in financial institutions. Centralized data lake: S3 acts as the central data lake where all data from different domains can reside in its raw or processed form. Easy data access: Athena provides a serverless interactive query service that allows data analysts to directly query data stored in S3 using standard SQL. This simplifies data exploration and analysis without managing servers. B: Data governance: Lake Formation helps establish data ownership, access control, and lineage for data products within the data mesh. It ensures data quality, security, and compliance with regulations. Fine-grained access control: Lake Formation allows you to define granular access policies for each data domain, ensuring only authorized users can access specific data sets. This aligns with the need for centralized control in a data mesh.

Must be B and E

i thing so

B and E . C - is not correct "AWS Glue DataBrew is a visual data preparation tool that makes it easier for data analysts and data scientists to clean and normalize data to prepare it for analytics and machine learning (ML)"

B and E

BE Given the requirements for implementing a data mesh architecture with centralized data governance, data analysis, and data access control, the two better choices from the options provided would be: B. Use Amazon S3 for data storage. Use Amazon Athena for data analysis. E. Use AWS Lake Formation for centralized data governance and access control.

Textbook question, the keyword data mesh means S3, the keyword data governance means LakeFormation
