SQL Server - What is the difference between BULKADMIN and ADMINISTER BULK OPERATIONS

Question

To grant user ability to run Bulk Insert T-SQL command, login/user needs to be granted:

1. BULKADMIN server role - or - ADMINISTER BULK OPERATIONS server-level permission
2. connect on target database
3. insert on target table

But what is the difference between BULKADMIN server role and ADMINISTER BULK OPERATIONS server-level permission ?

Answer 1

If we look at the SQL Server Permissions Poster (2017 edition):

It appears as though ADMINISTER BULK OPERATIONS covers bulkadmin in addition to OPENROWSET which allows access to external sources.
