As part of your industrial IoT solution, you have 10 wind turbines equipped with many sensors. All these sensors send thousands of telemetry data to an IoT hub. You need to build a solution that can provide real-time visibility and on-the-fly analysis of key data streams. You decide to use Time Series Insights (TSI). 
While creating the TSI environment, what should you configure to achieve your goal?

Answer options:

A.IoT Hub event source; TSI consumer group; warm storage
B.IoT Hub consumer group; TSI event source; warm storage, cold storage
C.IoT Hub Custom endpoint; TSI event source; cold storage; warm storage
D.IoT Hub consumer group; TSI event source; cold storage

Correct Answer: B
Option A is incorrect because the consumer group must be created in the IoT Hub and the event source must be configured in TSI.
Option B is CORRECT because you need to have a consumer group in your IoT Hub, exclusively for the TSI environment, which can use this as an event source. Because of the requirement for real-time analysis, enabling warm storage is recommended. Although it is optional, for this scenario adding cold storage is recommended.
Option C is incorrect because you need to use IoT Hub’s built-in endpoints to create a consumer group that TSI can use for ingesting data. Custom endpoints are not available for this purpose.
Option D is incorrect because due to the requirement for on-the-fly analysis, enabling warm storage is recommended. Although it is optional, for this scenario adding cold storage is recommended.
