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.
Kinesis Data Firehose supports the use of an AWS Lambda function for data transformation before delivering the data to a destination
A is the correct answer.
