AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 33

Question

A company runs an online marketplace web application on AWS. The application serves hundreds of thousands of users during peak hours. The company needs a scalable, near-real-time solution to share the details of millions of financial transactions with several other internal applications. Transactions also need to be processed to remove sensitive data before being stored in a document database for low-latency retrieval. What should a solutions architect recommend to meet these requirements?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Stream the transactions data into Amazon Kinesis Data Streams. Use AWS Lambda integration to remove sensitive data from every transaction and then store the transactions data in Amazon DynamoDB. Other applications can... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. Kinesis Data Streams ingests and processes high-volume real-time streaming data. This option meets the real-time / low-latency performance requirement.
