Then, restore each log backup taken before the time of failure from the most recentdifferential backup. E.^ Restore the latest full backup. Then, restore the latest differential backup. 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 page restore. H. Perform a partial restore. Correct Answer:^ C Section: Volume AExplanationExplanation/Reference:QUESTION 6 You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a reporting database. The transactional database is updated through aweb 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 also need to ensure that data loss is minimal.What should you do? A.^ Perform a partial restore.
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 recentdifferential 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. Correct Answer:^ F Section: Volume AExplanationExplanation/Reference:Requirements for Restoring PagesA 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 thefollowing 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 thefilegroup.^ 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 thecurrent 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 canprevent 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 withthe 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 theREPAIR_ALLOW_DATA_LOSS option.
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 recentdifferential backup. H. Restore the latest full backup. Then, restore the latest differential backup.

Section: Volume AExplanationExplanation/Reference:QUESTION 10 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 Correct Answer:^ C Section: Volume AExplanationExplanation/Reference:QUESTION 11 DRAG DROPYou 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
Section: Volume AExplanationExplanation/Reference: Reference:http://msdn.microsoft.com/en-us/library/ms151198.aspx QUESTION 12 You administer several Microsoft SQL Server 2012 database servers. Merge replication has been configured for an application that is distributed across officesthroughout 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. Correct Answer:^ A Section: Volume AExplanationExplanation/Reference: Explanation/Reference: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 agentruns: 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 Subscriberis 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 theLog Reader Agent, Distribution Agent, and Merge Agent. In addition to the profiles provided, you can create profiles suited to your application requirements. Anagent 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 tochange 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 usingthe new value automatically the next time they run.You might also have different profiles for different instances of an agent. For example, aMerge Agent that connects to the Publisher and Distributor over a dialup connection could use a set of parameters that are better suited to the slowercommunications link by using the slow link profile. QUESTION 13 DRAG DROPYou administer two Microsoft SQL Server 2012 servers named ServerA and ServerB. You use a database named AdventureWorks.You need to prepare the AdventureWorks database for database mirroring. ServerB will act as the mirror in a mirroring partnership along with ServerA.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 thecorrect order.) Select and Place:
