CORRECT ANSWER: D
Since the wording do not explicitly ask for the new database to reside on a different server, option D would be a better option, with less effort too.

• From an existing database (structure as well as data)
You can create a new template that has both the structural information and physical data files of an existing database. Databases created using such a template are identical to the source database. User-defined schemas and their data will be part of the created template. The source database must be local. Select this option when you want a template from which you can create an exact replica of the source database.
What about data? you only create a database using the template with no data…
I think A is the only correct answer
