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:
The deployment model must support changing the content of connection strings by using
parameters at execution time.
The deployment model must automatically log events to the SSISOB database.
Maximize performance at execution time.
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.)

A.
Use a project deployment model. Modify connection manager properties to use project
parameters.

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

C.
Use a package 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.

D.
Use a project deployment model. Modify connection manager properties to use package
parameters.
