You administer a single server that contains a Microsoft SQL Server 2016 default instance on which several production databases have been deployed.

You plan to install a new ticketing

application that requires the deployment of a database on the server.

The SQL login for this application requires sysadmin permissions. You need to ensure that the login for the ticketing application cannot access other production databases.

What should

you do?

A. Use the SQL Server default instance and enable Contained Databases.

B. Use the SQL Server default instance and configure a user-defined server role. Add the login for the ticketing application to this role.

C. Install a new named SQL Server ins

tance on the server.

D. Install a new default SQL Server instance on the server.

SQL Server supports multiple instances of SQL Server on a single server or processor, but only one instance can be the default instance. All others must be named in

stances. A computer can run multiple instances of SQL Server concurrently, and each instance runs independently of other instances.
