Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 323 discussion

Kinesis Data streams is real-time. Firehose is near real-time. DynamDB is not a relational DB and does not enforce fixed schemas on its tables. Answer is B

B is correct Amazon DynamoDB is designed to handle high-traffic, real-time data streams and can store JSON-formatted data without requiring fixed schemas. Kinesis Data Streams can capture and transform the data in real-time, and by sending it directly to DynamoDB, you can leverage DynamoDB's NoSQL key-value store with flexible schema support. In fact, using Kinesis Data Streams to feed DynamoDB is a common pattern for building scalable, high-traffic applications that require real-time data processing.

By using Amazon Kinesis Data Firehose to send the data to Amazon Keyspaces, the company can efficiently stream real-time data and store it in a schema-less database, meeting the requirement for flexibility and real-time processing. Option B is not correct: While Amazon Kinesis Data Streams can handle real-time data, it does not directly integrate with Amazon DynamoDB. Additional steps are needed to process and insert the data into DynamoDB. Additionally, DynamoDB, though flexible, typically benefits from having a defined schema for efficient access patterns.

B, Firehose+ DynamoDB https://aws.amazon.com/blogs/database/working-with-json-data-in-amazon-dynamodb/

Option D - By using Amazon Kinesis Data Firehose to send the environmental data to Amazon Keyspaces (for Apache Cassandra), you can leverage a fully managed streaming data ingestion service and a schema-flexible NoSQL database, meeting the requirements for real-time processing and storage of data without a fixed schema.

Answer: B Option B leverages the strengths of both Kinesis Data Streams and DynamoDB to provide a scalable and real-time solution for ingesting and storing JSON-format data without fixed schemas. Option A: Kinesis Data Firehose: While suitable for real-time data delivery, it has a limited set of destinations, not including DynamoDB.

Option B

Correct B

Load json format to DynamoDB

Correct is B Amazon DynamoDB: DynamoDB is a NoSQL database service provided by AWS that does not require fixed schemas

B is right option. D is not correct because Firehose can not write to Keyspaces.

Correct is B
