SAP-C02 Question 184
Select 4A financial services company is building a real-time fraud detection platform. The system must process large amounts of streaming financial transactions, detect potential fraud in near real-time, and store the data for auditing purposes. The solution must be cost-effective, scalable, and resilient. Which combination of AWS services should the company use to meet these requirements?
- A
Amazon Kinesis Data Streams to ingest and process streaming data in real-time
- B
AWS Lambda to apply fraud detection logic to the streaming data
- C
Amazon RDS for PostgreSQL to store streaming data for auditing
- D
Amazon S3 to store streaming data for auditing
- E
Amazon DynamoDB to store fraud detection results with low-latency access
Show answer and explanation
Correct answers: A, B, D, E
Explanation
The combination of Amazon Kinesis Data Streams, AWS Lambda, Amazon S3, and Amazon DynamoDB provides a cost-effective, scalable, and resilient solution for real-time fraud detection. Kinesis handles the ingestion of streaming data, Lambda processes the data with fraud detection logic, S3 stores the raw data for auditing purposes, and DynamoDB stores detection results for low-latency access. Amazon RDS is not suitable for this use case due to its limitations in handling real-time streaming data and higher operational costs.
- A. Correct.
Amazon Kinesis Data Streams is a fully managed service designed to handle large-scale real-time data ingestion and processing, making it suitable for fraud detection use cases.
- B. Correct.
AWS Lambda is a serverless compute service that can process data from Kinesis and apply the fraud detection logic in near real-time.
- C. Incorrect.
Amazon RDS for PostgreSQL is not the best choice for storing streaming data due to its relational nature and higher costs for real-time ingestion and querying at scale.
- D. Correct.
Amazon S3 is cost-effective and scalable for storing large amounts of data, making it ideal for keeping the streaming data for auditing purposes.
- E. Correct.
Amazon DynamoDB is a low-latency NoSQL database that provides fast access to fraud detection results and is well-suited for storing real-time detection outcomes.
