Exam 70-764 topic 1 question 57 discussion

Actual exam question from Microsoft's 70-764

Question #: 57
Topic #: 1

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

Show Suggested Answer

Suggested Answer: C 🗳️
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.

Just isolate the account by giving it its own SQL Server instance. A Contained Database at first glance sounds good, but is something that is not a good choice in this case. A contained database is a database that is isolated from other databases and from the instance of SQL Server/ SQL Database (and the master database) that hosts the database.
