Actual exam question from Microsoft's 70-764

Question #: 66
Topic #: 1

You administer a Microsoft SQL Server 2016 server that hosts a transactional database and a reporting database. The transactional database is updated through a web application and is operational throughout the day.
The reporting database is only updated from the transactional database.
The recovery model and backup schedule are configured as shown in the following table:

At 14:00 hours, you discover that pages 71, 520, and 713 on one of the database files are corrupted on the reporting database.
You need to ensure that the databases are restored.
You also need to ensure that data loss is minimal. What should you do?

A. Perform a partial restore.
B. Restore the latest full backup, and restore the latest differential backup. Then, restore each log backup taken before the time of failure from the most recent differential backup.
C. Restore the latest full backup.
D. Restore the latest full backup, and restore the latest differential backup. Then, restore the latest log backup.
E. Perform a page restore.
F. Restore the latest full backup. Then, restore each differential backup taken before the time of failure from the most recent full backup.
G. Perform a point-in-time restore.
H. Restore the latest full backup. Then, restore the latest differential backup.

Show Suggested Answer

Suggested Answer: H 🗳️
At restore time, before you restore a differential backup, you must restore its base. Then, restore only the most recent differential backup to bring the database forward to the time when that differential backup was created. Typically, you would restore the most recent full backup followed by the most recent differential backup that is based on that full backup.

A page restore cannot be done since the database is using the simple recovery model.

The corruption occured after the latest differential backup, so, just restore via a full backup and then use the latest differential backup. Since the recovery mode is set to Simple, a transactional log, point-in-time restore cannot be done.
