DVA-C02 Question #728: Real Exam Question with Answer & Explanation
The correct answer is B: Set JSONata as the query language in the state machine. Use JSONata expressions for data. Step Functions now supports JSONata and workflow variables, enabling powerful in-state data transformations, aggregation, and regex validation without extra Lambda code - minimizing operational overhead. JSONata handles complex transforms and regex, and variables manage intermedi
Question
A developer is creating an AWS Step Functions state machine for a customer onboarding process. The developer needs to perform advanced data transformations and needs to manage workflow state outputs effectively. The developer needs to aggregate results from workflow states and to validate data by using regular expressions. Which solution will meet these requirements with the LEAST operational overhead?
Options
- AConfigure AWS Lambda functions to perform data transformations. Use Pass states with intrinsic
- BSet JSONata as the query language in the state machine. Use JSONata expressions for data
- CBuild custom Step Functions SDK integrations to handle validations and data manipulations to
- DConfigure an Amazon DynamoDB table with streams to initiate data validation events through
Explanation
Step Functions now supports JSONata and workflow variables, enabling powerful in-state data transformations, aggregation, and regex validation without extra Lambda code - minimizing operational overhead. JSONata handles complex transforms and regex, and variables manage intermediate state across steps.
