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.

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
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:
At 16:20 hours, you discover that pages 17, 137, and 205 on one of the database files are
corrupted on the transactional database. You need to ensure that the transactional
database is 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. Perform a point-in-time restore.
D. Restore the latest full backup.
E. Restore the latest full backup, and restore the latest differential backup. Then, restore
the latest log backup.
F. Perform a page restore.
G. Restore the latest full backup. Then, restore each differential backup taken before the
time of failure from the most recent full backup.
H. Restore the latest full backup. Then, restore the latest differential backup.
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 readonly
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.
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
You administer three Microsoft SQL Server 2012 servers named ServerA, ServerB, and
ServerC.
ServerA is the acting principal and ServerB is the mirror.
You need to add ServerC as a witness to the existing mirroring session between ServerA
and ServerB. You need to achieve this goal without delaying synchronization.
Which three actions should you perform in sequence? (To answer, move the appropriate
actions from the list of actions to the answer area and arrange them in the correct order.)
Answer:
You administer a Microsoft SQL Server 2012 database.
You create an availability group named haContosoDbs. Your primary replica is available at
Server01\Contoso01.
You need to configure the availability group to have the highest availability. You also need
to ensure that no data is lost.
Which Transact-SQL statement should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
You administer several Microsoft SQL Server 2012 servers. Your company has a number
of offices across the world connected by using a wide area network (WAN).
Connections between offices vary significantly in both bandwidth and reliability.
You need to identify the correct replication method for each scenario.
What should you do? (To answer, drag the appropriate replication method or methods to
the correct location or locations in the answer area. Each replication method may be used
once, more than once, or not at all.)
Answer:
You administer several Microsoft SQL Server 2012 database servers. Merge replication
has been configured for an application that is distributed across offices throughout a wide
area network (WAN).
Many of the tables involved in replication use the XML and varchar (max) data types.
Occasionally, merge replication fails due to timeout errors.
You need to reduce the occurrence of these timeout errors.
What should you do?
A. Set the Merge agent on the problem subscribers to use the slow link agent profile.
B. Create a snapshot publication, and reconfigure the problem subscribers to use the
snapshot publication.
C. Change the Merge agent on the problem subscribers to run continuously.
D. Set the Remote Connection Timeout on the Publisher to 0.
Answer: A
Explanation:
When replication is configured, a set of agent profiles is installed on the Distributor. An
agent profile contains a set of parameters that are used each time an agent runs: each
agent logs in to the Distributor during its startup process and queries for the parameters in
its profile.
For merge subscriptions that use Web synchronization, profiles are downloaded and stored
at the Subscriber. If the profile is changed, the profile at the Subscriber is updated the next
time the Merge Agent runs. For more information about Web synchronization, see Web
Synchronization for Merge Replication.
Replication provides a default profile for each agent and additional predefined profiles for
the
Log Reader Agent, Distribution Agent, and Merge Agent. In addition to the profiles
provided, you can create profiles suited to your application requirements. An agent profile
allows you to change key parameters easily for all agents associated with that profile. For
example, if you have 20 Snapshot Agents and need to change the query timeout value (the
- QueryTimeout parameter), you can update the profile used by the Snapshot Agents and
all agents of that type will begin using the new value automatically the next time they run.
You might also have different profiles for different instances of an agent. For example, a
Merge Agent that connects to the Publisher and Distributor over a dialup connection could
use a set of parameters that are better suited to the slower communications link by using
the slow link profile.
