QUESTION 25
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).

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 your backup will continue if any invalid checksum is encountered. Which backup option should you use?

Under the simple recovery model, the file must belong to a read-only filegroup. Under the full or bulk-logged recovery model, before you can restore files, you must back up the active transaction log (known as the tail of the log).
Reference: Back Up a Transaction Log (SQL Server)
To restore a database that is encrypted, you must have access to the certificate or asymmetric key that was used to encrypt the database. Without the certificate or asymmetric key, the database cannot be restored. As a result, the certificate that is used to encrypt the database encryption key must be retained as long as the backup is needed.
