A shortcut's main benefit over a copy is what?
Why B is the answer
It avoids duplicating data
Data stays in place, so there is one copy to manage.
In detail
- A shortcut avoids duplicating data.
- Fewer copies mean fewer versions of the truth.
Use case
An illustrative scenario, not a real incident.
Three teams need one customer dataset. With shortcuts, they all read one copy, so there is no sync job and no drifting data.

Why the other options are wrong
- A. It removes the need for access control
- Access control still applies.
- C. It encrypts the source files
