Selected Answer: C
The correct answer is C. Azure Synapse Link for Azure Cosmos DB. Azure Synapse Link for Azure Cosmos DB creates a tight integration between Azure Cosmos DB and Azure Synapse Analytics, allowing you to run near real-time analytics over operational data in Azure Cosmos DB. It creates a "no-ETL" (Extract, Transform, Load) environment that allows you to analyze data directly without affecting the performance of the transactional workload, which is exactly what is required in this scenario. A. Azure Data Factory with Azure Cosmos DB and Azure Synapse Analytics connectors would require ETL operations which might impact the performance of the operational data store. B. Azure Synapse Analytics with PolyBase data loading is more appropriate for loading data from external data sources such as Azure Blob Storage or Azure Data Lake Storage. D. Azure Cosmos DB change feed doesn't directly address the need for analytics without affecting the performance of the operational data store.

Selected Answer: C
Azure Synapse Link for Azure Cosmos DB. Azure Synapse Link for Azure Cosmos DB is a cloud-native hybrid transactional and analytical processing (HTAP) capability that enables near real time analytics over operational data in Azure Cosmos DB. Azure Synapse Link creates a tight seamless integration between Azure Cosmos DB and Azure Synapse Analytics. It enables customers to run near real-time analytics over their operational data with full performance isolation from their transactional workloads and without an ETL pipeline https://learn.microsoft.com/en-us/azure/cosmos-db/synapse-link

A. Azure Data Factory with Azure Cosmos DB and Azure Synapse Analytics connectors Reason: While Azure Data Factory can move data from Cosmos DB to Synapse Analytics, it typically involves batch processing, which may not be real-time and could affect operational data performance during the ETL process. B. Azure Synapse Analytics with PolyBase data loading Reason: PolyBase is excellent for loading large volumes of data but is designed for structured data and batch loading, not continuous real-time analysis, and may impact the performance during large data transfers. D. Azure Cosmos DB change feed Reason: The change feed provides a continuous log of changes but requires additional processing to integrate with Synapse Analytics, which can complicate the solution and impact performance.
