Exam DAA-C01 Topic 1 Question 53 Discussion

Actual exam question for Snowflake's DAA-C01 exam
Question #: 53
Topic #: 1

You are designing a system to ingest data from a high-volume sensor network. The sensors send data in a custom binary format to an on-premise message queue (e.g., RabbitMQ). The data needs to be converted to a structured format (e.g., JSON) before being loaded into Snowflake. Choose the most effective approach to ensure data integrity, scalability, and near-real-time ingestion.

A. Develop a custom application that subscribes to the message queue, converts the binary data to JSON, and then uses the Snowflake JDBC driver to insert the data directly into Snowflake. B. Use a third-party data integration platform that supports connecting to message queues, converting binary data, and loading data into Snowflake. C. Create a Snowflake external function that connects to the message queue and converts the binary data to JSON during the COPY INTO process. D. Deploy a stream processing engine (e.g., Apache Kafka Streams, Apache Flink) on-premise to consume messages from the queue, convert the binary data to JSON, and then write the JSON data to a cloud storage location (e.g., S3, Azure Blob Storage, GCS). Configure Snowpipe to load the JSON data into Snowflake. E. Use an on-premise gateway to expose the RabbitMQ as a REST API, then use a Snowflake external function to call the exposed API.

Suggested Answer: B,D Vote an answer

Options B and D provide robust and scalable solutions. Option B leverages a dedicated data integration platform, which often provides pre-built connectors for message queues, binary data conversion capabilities, and optimized Snowflake integration. Option D utilizes a stream processing engine, offering the scalability and fault tolerance necessary for high-volume data streams. The stream processing engine can perform the binary-to-JSON conversion and write the structured data to cloud storage for Snowpipe to ingest. Option A lacks scalability and fault tolerance. Option C might be limited by the external function execution time and concurrency. Option E creates an unnecesssary intermediate REST API which can affect performance and also does not inherently solve the binary conversion problem.
