[All AI-100 Questions]

You need to design an application that will analyze real-time data from financial feeds.
The data will be ingested into Azure IoT Hub. The data must be processed as quickly as possible in the order in which it is ingested.
Which service should you include in the design?

  • A. Azure Data Factory
  • B. Azure Queue storage
  • C. Azure Stream Analytics
  • D. Azure Notification Hubs
  • E. Apache Kafka
  • F. Azure Event Hubs
Show Suggested Answer Hide Answer
Suggested Answer: C 🗳️
Stream processing can be handled by Azure Stream Analytics. Azure Stream Analytics can run perpetual queries against an unbounded stream of data. These queries consume streams of data from storage or message brokers, filter and aggregate the data based on temporal windows, and write the results to sinks such as storage, databases, or directly to reports in Power BI. Stream Analytics uses a SQL-based query language that supports temporal and geospatial constructs, and can be extended using JavaScript.
Incorrect Answers:
E: Apache Kafka is used for ingestion, not for stream processing.
F: Azure Event Hubs is used for ingestion, not for stream processing.

To analyze real-time data from financial feeds, ingest it into Azure IoT Hub, and process it as quickly as possible in the order of ingestion, you should include both C. Azure Stream Analytics and F. Azure Event Hubs in the design.

I felt 'processing the data in the order it was ingested' refers to a Queue storage, or is Stream Analytics capable of handling data in a queue manner, preserving the order?

By default, Stream Analytics processes events by arrival time: https://docs.microsoft.com/en-us/azure/stream-analytics/event-ordering
