Question 500
An architecture review recommends this solution: Build a governed S3-centered data lake with AWS Glue metadata and appropriate analytics services. The motivating situation is: A legacy reporting ETL cluster requires durable raw data sharing and easier scale-out queries across departments. Which architectural reasoning is most accurate for the choice?
Explanation
Correct Answer
This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Build a governed S3-centered data lake with AWS Glue metadata and appropriate analytics services. The expected supporting evidence is: Separate analysts query approved lake datasets without direct access to the legacy ETL host.
Incorrect Answers
Mainframe batch and transaction semantics were treated as if they were ordinary Linux workloads. The stated evidence instead indicates: All analytics jobs depend on a single custom ETL server and its directly attached storage.
Tight synchronous coupling propagates a noncritical downstream failure to the primary transaction. The stated evidence instead indicates: All analytics jobs depend on a single custom ETL server and its directly attached storage.
A direct S3 SDK rewrite was imposed on workloads that cannot change their file interface. The stated evidence instead indicates: All analytics jobs depend on a single custom ETL server and its directly attached storage.
