Final answer:
The Fixed Server-Level role required to execute the BULK INSERT statement in SQL Server is the bulkadmin role. This role is specifically designed for bulk operations to import data efficiently into SQL Server databases.
Step-by-step explanation:
To execute a BULK INSERT statement in SQL Server, you need to have the appropriate permissions. The correct Fixed Server-Level role for this operation is the bulkadmin role. This role specifically allows users to run the BULK INSERT statement as well as BULK commands which are used to import data into SQL Server databases efficiently.
Other roles mentioned such as serveradmin, securityadmin, and dbcreator have their distinct responsibilities. The serveradmin has wide-ranging server-wide configurations, the securityadmin manages logins and related security tasks, and the dbcreator can create, alter, drop, and restore databases. However, none of these roles are specifically designed for bulk operations which are the purview of the bulkadmin role.
Therefore, if the requirement is to execute the BULK INSERT statement, assigning the bulkadmin role to a user would give them the necessary permissions without the broader access that comes with the other roles.
