You administer a Microsoft SQL Server 2012 server that hosts a transactional database
and a reporting database.
The transactional database is updated through a webapplication 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 onthe
reporting database.
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 thelatest differential backup.
Explanation:
File restore
Restores a file or filegroup in a multi-filegroup database. Note that under the simple
recovery model, the file must belong to a read-only filegroup. After a full file restore, a
differential file backup can be restored.
Page restore
Restores individual pages. Page restore is available only under thefull and bulk-logged
recovery models
Piecemeal restore
Restores the database in stages, beginning with theprimary filegroup and one or more
secondary filegroups. A piecemeal restore begins with a RESTORE DATABASE using the
PARTIAL option and specifying one or more secondaryfilegroups to be restored
Ideally, a page restore would have been the best solution. However, considering the REPORTING DB is running in SIMPLE recovery mode, a Page Restore won’t be possible. It is only available with the FULL or BULK-LOGGED recovery modes.
Hence, I’ll take option H. Restore latest FULL & latest DIFFERENTIAL backups.
