Question:

You administer a Microsoft SQL Server 2012 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:
The differential backup of the reporting database
fails. Then, the reporting database fails at 14:00 hours.
You need to ensure that the reporting database is
restored. You also need to ensure that data loss is minimal.
What should you do?
A. Restore the latest full backup, and restore the
latest differential backup. Then, restore the latest log backup.
B. Perform a point-in-time restore. C Restore the latest
full backup.
C. 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.
D. Restore the latest full backup. Then, restore the
latest differential backup.
E. Restore the latest full backup. Then, restore each
differential backup taken before the time of failure from the most recent full
backup.
F. Perform a page restore.
G. Perform a partial restore.

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

E. Perform a page restore.
F. Restore the latest full backup. Then, restore each

backup.
G. Perform a point-in-time restore.
H. Restore the latest full backup. Then, restore the
latest differential backup.

Answer: H

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 the full and bulk-logged recovery models
Piecemeal restore
Restores the database in stages, beginning with the
primary filegroup and one or more secondary filegroups. A piecemeal restore
begins with a RESTORE DATABASE using the PARTIAL option and specifying one or
more secondary filegroups to be restored

H. Restore the latest full backup. Then, restore the

Answer: F

Explanation:
Requirements for Restoring Pages
A page restore is subject to the following
requirements:
• The databases must be using the full or bulk-logged
recovery model. Some issues exist if you are using the bulk-logged model. For
more information, see the following section.
• Pages in read-only filegroups cannot be restored.
Trying to make a filegroup read-only will fail if there is a page restore going
on at the same time in the filegroup.
• The restore sequence must start with a full, file,
or filegroup backup.
• A page restore requires an unbroken chain of log
backups up to the current log file, and they must all be applied so that the
page is brought up to date with the current log file.
• As in a file-restore sequence, in each restore step,
you can add more pages to the roll forward set.
• A database backup and page restore cannot be run at
the same time.
Bulk-logged Recovery Model and Page Restore
For a database that uses the bulk-logged recovery
model, page restore has the following additional conditions:
• Backing up while filegroup or page data is offline
is problematic for bulk-logged data, because the offline data is not recorded
in the log. Any offline page can prevent backing up the log. In this cases,
consider using
• DBCC REPAIR, because this might cause less data loss
than restoring to the most recent backup.
• If a log backup of a bulk-logged database encounters
a bad page, it fails unless WITH
• CONTINUE_AFTER_ERROR is specified.
• Page restore generally does not work with
bulk-logged recovery.
• A best practice for performing page restore is to
set the database to the full recovery model, and try a log backup. If the log
backup works, you can continue with the page restore. If the log backup fails,
you either have to lose work since the previous log backup or you have to try
running DBCC must be run with the REPAIR_ALLOW_DATA_LOSS option.

Question:

You administer a Microsoft SQL Server 2012 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:
One of the hard disk drives that stores the reporting
database fails at 16:40 hours.
You need to ensure that the reporting database is
restored. You also need to ensure that data loss is minimal. What should you
do?
A. Restore the latest full backup. Then, restore each
differential backup taken before the time of failure from the most recent full
backup.
B. Perform a partial restore.
C. Restore the latest full backup, and restore the
latest differential backup. Then, restore the latest log backup.
D. Perform a point-in-time restore.
E. Restore the latest full backup.
F. Perform a page restore.
G. 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.
H. Restore the latest full backup. Then, restore the
latest differential backup.

Answer: E

Explanation:
Original answer is H... but I don't particularly like
any... restore full on reporting and run update again or use transactional full
and 2 O'clock differential from Transaction db to restore the reporting db. I'm
going for something missing from question or answer
