Designing and Implementing an Azure AI Solution (legacy) — Question 17

You are developing an app that consumes data from several Azure IoT Edge devices.
You need to implement a storage solution for the app. Your solution must allow data to be queried in real-time as it streams into the solution. You need to ensure that your solution provides the least amount of latency for loading data.
You want the data files to persist on the devices for at least 14 days.
What storage solution should you implement?

Answer options

Correct answer: C

Explanation

The correct answer is C, Azure HDInsight Hadoop cluster, as it is designed for processing large datasets with low latency, making it suitable for real-time data queries. Options A and B do not provide the necessary real-time querying capabilities, and D, while having In-Memory OLTP advantages, may not handle the volume and persistence needs as effectively as a Hadoop cluster for this scenario.
