Amazon Web Services Data-Engineer-Associate Exam With Confidence Using Practice Dumps

Option B is correct because Amazon Q in QuickSight is the AWS feature built specifically for natural language interaction with business data. AWS documentation explains that Amazon Q in QuickSight lets users ask questions in natural language, generate summaries and data stories, and create visuals from author prompts. AWS Prescriptive Guidance also notes that users can generate insights with natural language prompts and that they do not have to write SQL queries or learn complex BI tooling. That matches the requirement that some analysts lack SQL knowledge and need to create reports frequently with minimal effort.

Option A is not the best answer because zero-ETL access addresses data movement and integration, not natural-language dashboard creation. Option C introduces another analytics platform and therefore more operational effort. Option D provides access to data, but federated querying still does not address the key requirement for natural-language dashboard and report generation for nontechnical analysts. The AWS-native feature that directly solves this problem with the least additional management is Amazon Q in QuickSight.

S3 Lifecycle policies automate data retention and deletion. By specifying an expiration rule for 7 years, objects older than that period are permanently deleted without manual intervention.

“To automatically delete aged data, configure an S3 Lifecycle rule with an expiration policy for objects older than the retention period.”

When AWS Glue jobs run inside a private subnet, they must use secure and supported methods to access external databases. AWS Glue supports JDBC connections to on-premises databases, but best practices require secure credential management and explicit driver configuration.

Using a JDBC driver stored in Amazon S3 allows Glue to connect to PostgreSQL without relying on default drivers. Storing credentials in AWS Secrets Manager eliminates hard-coded credentials and enables secure rotation, aligning with AWS security best practices.

Simply specifying credentials inline is less secure and not recommended. SASL connections are not supported for PostgreSQL JDBC connections. Security groups alone do not establish connectivity or authentication.

Therefore, Option D is the correct and production-grade solution.
