The solution must NOT affect the performance of the web apps.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Enable Azure Synapse Link for the account and Analytical store on the container.
- B. In an Azure Synapse Analytics serverless SQL pool, create a view that uses OPENROWSET and the CosmosDB provider.
- C. In an Apache Spark pool in Azure Synapse, create a table that uses cosmos.oltp as the data source.
- D. Create a private endpoint connection to the account.
- E. In an Apache Spark pool in Azure Synapse, create a table that uses cosmos.olap as the data source.
