Administering Microsoft SQL Server 2012 Databases

Question No: 1 – (Topic 1)

You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN).

The financial database has the following characteristics:

->A data file of 2 terabytes is located on a dedicated LUN (drive D).

->A transaction log of 10 GB is located on a dedicated LUN (drive E).

->Drive D has 1 terabyte of free disk space.

->Drive E has 5 GB of free disk space.

The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.

The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database.

These data load operations must occur in the minimum amount of time.

A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.

You need to ensure that your backup will continue if any invalid checksum is encountered. Which backup option should you use?

  1. STANDBY

  2. Differential

  3. FULL

  4. CHECKSUM

  5. BULK_LOGGED

  6. CONTINUE_AFTER_ERROR

  7. SIMPLE

  8. DBO_ONLY

  9. COPY_ONLY

  10. SKIP

  11. RESTART

  12. Transaction log

  13. NO_CHECKSUM

  14. NORECOVERY

    Question No: 6 – (Topic 1)

    You administer a Microsoft SQL Server 2012 server. One of the databases on the server

    supports a highly active OLTP application.

    Users report abnormally long wait times when they submit data into the application.

    You need to identify which queries are taking longer than 1 second to run over an extended period of time.

    What should you do?

    1. use SQL Profiler to trace all queries that are processing on the server. Filter queries that have a Duration value of more than 1,000.

    2. Use sp_configure to set a value for blocked process threshold. Create an extended event session.

    3. Use the Job Activity monitor to review all processes that are actively running. Review the Job History to find out the duration of each step.

    4. Run the sp_who command from a query window.

    5. Run the DBCC TRACEON 1222 command from a query window and review the SQL Server event log.

    Question No: 7 – (Topic 1)

    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?

    1. Set the Merge agent on the problem subscribers to use the slow link agent profile.

    2. Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication.

    3. Change the Merge agent on the problem subscribers to run continuously.

    4. Set the Remote Connection Timeout on the Publisher to 0.

    Answer: A

    Explanation: 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 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.

    Question No: 8 DRAG DROP – (Topic 1)

    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.)

    Question No: 9 – (Topic 1)

    You administer a single server that contains a Microsoft SQL Server 2012 default instance.

    You plan to install a new application that requires the deployment of a database on the server. The application login requires sysadmin permissions.

    You need to ensure that the application login is unable to access other production databases.

    What should you do?

    1. Use the SQL Server default instance and configure an affinity mask.

    2. Install a new named SQL Server instance on the server.

    3. Use the SQL Server default instance and enable Contained Databases.

    4. Install a new default SQL Server instance on the server.

    Answer: B

    Question No: 10 DRAG DROP – (Topic 1)
