Administering a SQL Database Infrastructure — Question 70

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?

Answer options

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

Correct answer: C

Explanation

The correct option is C because installing a new named SQL Server instance allows for complete isolation of the ticketing application database from the production databases. The other options either do not provide the necessary isolation or are not suitable for the requirements of limiting access while granting sysadmin permissions.
