Explanation:
The DAC is implemented as a specific TCP endpoint in a SQL Server instance that is always attached to a dedicated UMS. The DAC was created to provide a connection that could always be used by a member of the sysadmin role to access a SQL Server instance, thereby guaranteeing that an administrator could not be locked out of SQL Server due to resource allocation issues. You can connect to the DAC in two ways:
1. Via SQLCMD or
2. Through the query window in SSMS.
