HOTSPOT -
You are planning a design pattern based on the Kappa architecture as shown in the exhibit.
Which Azure service should you use for each layer? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Layer 1: Azure Data Factory -
Layer 2: Azure Databricks -
Azure Databricks is fully integrated with Azure Data Factory .

Speed layer: Cosmos DB, Long-term store: Synapse
Agree with this solution
Agree. I saw same question in another sample test .. Answer mention above is right.
Speed layer: Cosmos , Long-term : Synapse
i don't think this's the right answer
There must be a reason why you said that
speed layer should be Cosmos DB, based on following article. Long term is correct. Data stored in Parquets. https://azure.microsoft.com/en-us/blog/lambda-architecture-using-azure-cosmosdb-faster-performance-low-tco-low-devops/
The kappa architecture was proposed by Jay Kreps as an alternative to the lambda architecture. It has the same basic goals as the lambda architecture, but with an important distinction: All data flows through a single path, using a stream processing system ,Analytical data store Azure Synapse Analytics, Azure Data Explorer, HBase, Spark, or Hive. Processed real-time data can be stored in a relational database such Synapse Analytics, Azure Data Explorer, a NoSQL store such as HBase, or as files in distributed storage over which Spark or Hive tables can be defined and queried. https://docs.microsoft.com/en-us/azure/architecture/data-guide/big-data/real-time-processing
Cosmos DB + ASA fit appropriately for this question I think.
