Question 1

A manufacturing company has 5,000 factory machines equipped with sensors. The sensors generate 10 TB of time-series telemetry data per day.

Data analysts need to perform interactive, ad-hoc queries over the last 6 months of data to identify anomaly patterns. The queries often involve complex aggregations, time-windowing, and joining massive datasets. The solution must provide sub-second query performance.

Which TWO Azure services should you combine to ingest and analyze this data? (Select TWO)

Accepted Answer

Identify the ingestion service for high-throughput telemetry (Event Hubs) and the analytics engine optimized for time-series data (Data Explorer).

Question 2
