Question ID 22649

You are designing a SQL Server Integration Services (SSIS) solution. The solution will contain an SSIS project that includes several SSIS packages. Each SSIS
package will define the same connection managers and variables. You have the following requirements:
• Ensure that the deployment model supports changing the content of connection strings by using parameters at execution time.
• Ensure that the deployment model automatically starts from calls to the catalog.start_execution stored procedure in the SSISDB database.
• Maximize performance at execution time.
• Minimize development effort.
You need to design a solution that meets the requirements.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

Option A

Use a project deployment model. Modify connection manager properties to use project parameters. Ensure that the SSISDB database is created.

Option B

Use a project deployment model. Configure connections in an XML configuration file referenced by an environment variable that corresponds to the SQL Server environment of each SSIS package.

Option C

Use a package deployment model. Use a SQL Server package configuration with a common filter. Change the contents of the SSIS Configurations table at runtime.

Option D

Use a package deployment model. Save each SSIS package to a file share that can be accessed from all environments.

Correct Answer A

Question ID 22650

You are designing an extract, transform, load (ETL) process for loading data from a SQL Server database into a large fact table in a data warehouse each day with
the prior day's sales data. The ETL process for the fact table must meet the following requirements:
• Load new data in the shortest possible time.
• Remove data that is more than 36 months old.
• Ensure that data loads correctly.
• Minimize record locking.
• Minimize impact on the transaction log.
You need to design an ETL process that meets the requirements. What should you do? (More than one answer choice may achieve the goal. Select the BEST
answer.)

Option A

Partition the destination fact table by date. Insert new data directly into the fact table and delete old data directly from the fact table.

Option B

Partition the destination fact table by date. Use partition switching and staging tables both to remove old data and to load new data.

Option C

Partition the destination fact table by customer. Use partition switching both to remove old data and to load new data into each partition.

Option D

Partition the destination fact table by date. Use partition switching and a staging table to remove old data. Insert new data directly into the fact table.

Correct Answer B
