  5. 5You deploy a database by using SQL Server 2014.
    The database contains a table named Table1.
    You need to recommend a solution to track all of the deletions executed on Table1.
    The solution must minimize the amount of custom code required.
    What should you recommend?
    1. AChange data capture
    2. BStatistics
    3. CA trigger
    4. DMaster Data Services
  6. 6You have four databases that are accessed by using an Online Transaction Processing (OLTP) application.
    The databases are stored on a server named SQL1 that has SQL Server 2014 installed.
    You plan to deploy an additional server that has SQL Server 2014 installed.
    You need to design a high-availability solution for the databases that meets the following requirements:
    – If SQL1 fails, the databases must be available.
    – Users must be able to run reports against a secondary copy of the databases.
    What should you include in the design? More than one answer choice may achieve the goal. Select the BEST answer.
    1. AAlwaysOn availability groups
    2. BDatabase mirroring
    3. CLog shipping
    4. DFailover Clustering
  7. 7You are troubleshooting an application that runs a query.
    The application frequently causes deadlocks.
    You need to identify which transaction causes the deadlock.
    What should you do? More than one answer choice may achieve the goal. Select the BEST answer.
    1. AQuery the sys.dm_exec_requests dynamic management view.
    2. BCreate a trace in SQL Server Profiler that contains the Deadlock graph event.
    3. CQuery the sys.dm_exec_sessions dynamic management view.
    4. DCreate an extended events session to capture deadlock information.
  8. 8You plan to create a database.
    The database will be used by a Microsoft .NET application for a special event that will last for two days.
    During the event, data must be highly available.
    After the event, the database will be deleted.
    You need to recommend a solution to implement the database while minimizing costs.
    The solution must not affect any existing applications.
    What should you recommend? More than one answer choice may achieve the goal. Select the BEST answer.
    1. ASQL Server 2014 Enterprise
    2. BSQL Server 2014 Standard
    3. CSQL Azure
    4. DSQL Server 2014 Express with Advanced Services
  9. 9You are designing a database named DB1.
    Changes will be deployed to DB1 every Wednesday night.
    You need to recommend a strategy to deploy the changes to DB1.
    The strategy must meet the following requirements:
    – The strategy must not disrupt backup operations.
    – DB1 must be unavailable to users while the changes are deployed.
    – You must be able to undo quickly the entire operation.
    What should you recommend? More than one answer choice may achieve the goal. Select the BEST answer.
    1. APerform a copy-only database backup before the changes are deployed.
      If the deployment fails, restore the database to another server and recover the original
      Objects from the restored database.
    2. BCreate a database snapshot.
      If the deployment fails, recover the objects from the database snapshot.
    3. CCreate a database snapshot.
      If the deployment fails, revert the database to the database snapshot.
    4. DPerform a full database backup before the changes are deployed.
      If the deployment fails, restore the database to another server and recover the original
      objects from the restored database.
  10. 10You are designing a SQL Server database for an order fulfillment system.
    You create a table named Sales.Orders by using the following script:

    CREATE TABLE Sales.Orders
    (
    OrderID int IDENTITY (1,1) NOT NULL PRIMARY KEY,
    OrderDate date NOT NULL,
    CustomerID int NOT NULL
    );

    Each order is tracked by using one of the following statuses:
    – Fulfilled
    – Shipped
    – Ordered
    – Received

    You need to design the database to ensure that you can retrieve the status of an order on a given date.
    The solution must ensure that new statuses can be added in the future.

    You need to design the database to ensure that that you can retrieve the following information:
    ✑ The current status of an order
    ✑ The previous status of an order.
    ✑ The date when the status changed.

    The solution must minimize storage.
    What should you do? More than one answer choice may achieve the goal. Select the BEST answer.
    1. ATo the Sales.Orders table, add a column named Status that will store the order status.
      Update the Status column as the order status changes.
    2. BCreate a new table named Sales.OrderStatus that contains three columns named OrderID,
      StatusDate, and Status. Insert new rows into the table as the order status changes.
    3. CImplement change data capture on the Sales.Orders table.
    4. DTo the Sales.Orders table, add three columns named FulfilledDate, ShippedDate, and
      ReceivedDate. Update the value of each column from null to the appropriate date as the order status changes.
