Which recovery model should the database use?

You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a
storage area network (SAN).
The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D).
A transaction log of 10 GB is located on a dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday
between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15
hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of
data to the database.
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be
performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You need to ensure that the minimum amount of data is lost.

Is this right? isn’t the right question bulk logged, because of the bcp inserts??

L BULK_LOGGED

The requirement :
“These data load operations must occur in the minimum amount of time.” suggests use bulk recovery.

On the other hand the requirement :
“You need to ensure that the minimum amount of data is lost.” suggests full recovery

I think I would go with L.

But not a nice question.

I think that the the question is clear:
The Finance department loads large CSV files into a number of tables each business day at 11:15
hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of
data to the database. (…)
“Which recovery model should the database use?”

In this case of BULK INSERT the recovey model should by BULK_LOGGED, this is the most correct answer.

“You need to ensure the minimum amount of data is lost”

This requirement can only be fulfilled using the FULL recovery mode. Bulk-Logged mode is minimally logged and does not allow Point-in-time restores is required.
