Kafka should be an event reader, but data processing should be done by Azure Databricks & store in Cosmos DB or Azure SQL. Given answer looks correct to me

Telemetry data should be stored in NOSQL database preferably Cosmos DB or blob storage. However in this question, Cosmos DB is not an option given. If given that would have been the best answer. Coming to why Azure Server. Below is what the case study states and storage doesn't support query language Requirement :The solution must allow for searches of vehicle images by license plate to support law enforcement investigations. Searches must be able to be performed using a query language and must support fuzzy searches to compensate for license plate detection errors. https://docs.microsoft.com/en-us/azure/architecture/reference-architectures/data/stream-processing-databricks
