An Amazon Kinesis Data Firehose delivery stream is receiving customer data that contains personally identifiable information. A developer needs to remove pattern-based customer identifiers from the data and store the modified data in an Amazon S3 bucket.
What should the developer do to meet these requirements?

A. Implement Kinesis Data Firehose data transformation as an AWS Lambda function. Configure the function to remove the customer identifiers. Set an Amazon S3 bucket as the destination of the delivery stream.
B. Launch an Amazon EC2 instance. Set the EC2 instance as the destination of the delivery stream. Run an application on the EC2 instance to remove the customer identifiers. Store the transformed data in an Amazon S3 bucket.
C. Create an Amazon OpenSearch Service instance. Set the OpenSearch Service instance as the destination of the delivery stream. Use search and replace to remove the customer identifiers. Export the data to an Amazon S3 bucket.
D. Create an AWS Step Functions workflow to remove the customer identifiers. As the last step in the workflow, store the transformed data in an Amazon S3 bucket. Set the workflow as the destination of the delivery stream.

Selected Answer: A

A) Correct - AWS Firehose supports Lambda transforms natively. This is scalable, cost-effective, and integrates seamlessly to remove PII before storing in S3. B) Incorrect - EC2 adds cost, maintenance, and complexity. Not suitable for a real-time, serverless transformation workflow. C) Incorrect - OpenSearch is not designed for stream processing or PII removal. It’s primarily for search and analytics, not transformation. D) Incorrect - Step Functions are not supported as a Firehose destination, and this adds unnecessary orchestration overhead.
