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?

Explanation/Reference: 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 instances. A computer can run multiple instances of SQL Server concurrently, and each instance runs independently of other instances. References: https://msdn.microsoft.com/en-us/library/ms143531(v=SQL.105).aspx
