A) Pause the columnstore index.
B) Drop the columnstore index.
C) Change the non-clustered columnstore index to be a clustered columnstore index.
D) Change the recovery model of the database to Bulk-logged.

2. You are developing a SQL Server Integration Services (SSIS) project that contains a project Connection Manager and multiple packages.
All packages in the project must connect to the same database. The server name for the database must be set by using a parameter named ServerParam when any package in the project is executed.
You need to develop this project with the least amount of development effort.

Which data flow components should you use to identify modified data? (Each correct answer presents a complete solution. Choose all that apply.)

A) Data Conversion
B) Aggregate
C) Lookup
D) Multicast
E) Slowly Changing Dimension
