Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 107
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A bicycle sharing company is developing a multi-tier architecture to track the location of its bicycles during peak operating hours. The company wants to use these data points in its existing analytics platform. A solutions architect must determine the most viable multi-tier option to support this architecture. The data points must be accessible from the REST API.
Which action meets these requirements for storing and retrieving location data?

  • A. Use Amazon Athena with Amazon S3.
  • B. Use Amazon API Gateway with AWS Lambda.
  • C. Use Amazon QuickSight with Amazon Redshift.
  • D. Use Amazon API Gateway with Amazon Kinesis Data Analytics.

Selected Answer: B
API Gateway is needed to get the data so option A and C are out. “The company wants to use these data points in its existing analytics platform” so there is no need to add Kynesis. Option D is also out. This leaves us with option B as the correct one.

While API Gateway and Lambda can work together for processing requests, this setup doesn't efficiently handle continuous real-time data streaming and analysis, which is required for tracking the bicycle locations. Lambda is stateless and is better suited for on-demand execution, not for real-time analytics of streaming data. So, the correct option is D

You are right, but it clearly say "store data". AWS Lambda don't store data, Kinesis could.

AWS Lambda provides a serverless way to process incoming requests and interact with a storage backend. This solution can store location data in a service like Amazon DynamoDB or Amazon S3 and use Lambda functions to retrieve and serve this data through the API Gateway. This is cost-effective, scalable, and straightforward for real-time queries.

B might work but D works better. B requieres API gateway + lambda for data input & output, whereas D is a broader solution, as Kinesis Data Analytics APIs can be used to extract and process data better that API Gateway + Lambdas. Also, Kinesis is highly recommended for telemetry data which is the question scenario. @See Kinesys flexible API (https://aws.amazon.com/documentation-overview/kinesis-data-analytics/)

Also by using kinesis the analytics platform will have a storing buffer to take & process data through the kinesys API. The lambda aproach in the B scenario is to wide and leaves many loose ends.

AWS Lambda is a serverless compute service that can be used to run code in response to specific events, such as changes to data in an Amazon S3 bucket or updates to a DynamoDB table. It could be used to process the location data, but it doesn't provide storage solution. Therefore, it would not be the best option for storing and retrieving location data in this scenario.

I dont understand why you will vote B? how are you going to store data with just lambda? > Which action meets these requirements for storing and retrieving location data In this use case there will obviously be a ton of data and you want to get real-time location data of the bicycles, and to analyze all these info kinesis is the one that makes most sense here.

Lambda isn't storing the data themselves. It's triggering the data store to the company's "existing data analytics platform"

Selected Answer: D
D. Use Amazon API Gateway with Amazon Kinesis Data Analytics. Why? Real-time Data Processing: Amazon Kinesis Data Analytics can process streaming data (e.g., bicycle locations) in real-time. REST API Access: Amazon API Gateway can provide a secure REST API for accessing the processed data. Scalability & Performance: Kinesis efficiently ingests large volumes of data during peak hours. Integration with Analytics: The processed data can be stored in Amazon S3, DynamoDB, or Redshift for further analytics.

lambda can store data in db which is not mentioned but can be implemented, wherein kinesis data analytics would be more complex to implement just for simple location tracking. Also, a data analytics tool is already there. Hence, B is more suitable.

Amazon Kinesis Data Analytics allows you to build more complex analytics applications that support flexible processing choices and robust fault-tolerance with exactly-once processing without duplicates, and analytics that can be performed over an entire data stream across multiple logical partitions. With KDA, you can analyze data over multiple types of aggregation windows (tumbling window, stagger window, sliding window, session window) using either the event time or the processing tim
