    NEW QUESTION 3
    Note: This question is part of a series of questions that use the same or similar answer choices. An Answer choice may be correct for more than one question in the series. Each question independent of the other questions in this series. Information and details provided in a question apply only to that question.
    You are a database developer for a company. The company has a server that has multiple physical disks. The disks are not part of a RAID array. The server hosts three Microsoft SQL Server instances. There are many SQL jobs that run during off-peak hours.
    You observe that many deadlocks appear to be happening during specific times of the day.
    You need to monitor the SQL environment and capture the information about the processes that are causing the deadlocks.
    What should you do?

    • A. Create a sys.dm_os_waiting_tasks query.
    • B. Create a sys.dm_exec_sessions query.
    • C. Create a PerformanceMonitor Data Collector Set.
    • D. Create a sys.dm_os_memory_objects query.
    • E. Create a sp_configure ‘max server memory’ query.
    • F. Create a SQL Profiler trace.
    • G. Create a sys.dm_os_wait_stats query.
    • H. Create an Extended Event.

    Answer: F

    Explanation: To view deadlock information, the Database Engine provides monitoring tools in the form of two trace flags, and the deadlock graph event in SQL Server Profiler.
    Trace Flag 1204 and Trace Flag 1222
    When deadlocks occur, trace flag 1204 and trace flag 1222 return information that is captured in the SQL Server error log. Trace flag 1204 reports deadlock information formatted by each node involved in the deadlock. Trace flag 1222 formats deadlock information, first by processes and then by resources. It is possible to enable both trace flags to obtain two representations of the same deadlock event.

      NEW QUESTION 5
      You use Microsoft SQL Server Profile to evaluate a query named Query1. The Profiler report indicates the following issues:
      At each level of the query plan, a low total number of rows are processed.
      The query uses many operations. This results in a high overall cost for the query. You need to identify the information that will be useful for the optimizer.
      What should you do?

      • A. Start a SQL Server Profiler trace for the event class Performance statistics in the Performance eventcategory.
      • B. Create one Extended Events session with the sqlserver.missing_column_statistics event added.
      • C. Start a SQL Server Profiler trace for the event class Soft Warnings in the Errors and Warnings event category.
      • D. Create one Extended Events session with the sqlserver.error_reported event added.

      Answer: A

      Explanation: The Performance Statistics event class can be used to monitor the performance of queries, stored procedures, and triggers that are executing. Each of the six event subclasses indicates an event in the lifetime of queries, stored procedures, and triggers within the system. Using the combination of these event subclasses and the associated sys.dm_exec_query_stats, sys.dm_exec_procedure_stats and sys.dm_exec_trigger_stats dynamic management views, you can reconstitute the performance history of any given query, stored procedure, or trigger.

      NEW QUESTION 6
      You have the following stored procedure that is called by other stored procedures and applications:
      70-762 dumps exhibit
      You need to modify the stored procedure to meet the following requirements:
      Always return a value to the caller.
      Return 0 if @Status is NULL.
      Callers must be able to use @Status as a variable.
      Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

      • A. Replace NULL values with 0. Add a PRINT statement to return @Status.
      • B. Add a RETURN statement.
      • C. Replace NULL values with 0. Add an output parameter to return @Status.
      • D. Replace NULL values with 0. Add a SELECT statement to return @Status.
      • E. Add a PRINT statement.
      • F. Add a SELECT statement to return @Status.
      • G. Add an output parameter to return @Status.

      Answer: BC

      Explanation: There are three ways of returning data from a procedure to a calling program: result sets, output parameters, and return codes.

      NEW QUESTION 7
      You are analyzing the memory usage of a Microsoft SQL Server instance. You need to obtain the information described on the following table.
      70-762 dumps exhibit
      Which performance counter should you use for each requirement? To answer, drag the appropriate performance counters to the correct requirements. Each performance counter may be used once, more than once or not at all. You may need to drag the split bat between panes or scroll to view content.
      NOTE: Each correct selection is worth one point.
      70-762 dumps exhibit

        Answer:

        Explanation: Requirement1: SQL Server: Memory Manager: Total Server Memory (KB)
        This counter specifies the amount of memory the server has committed using the memory manager. Requirement2: SQL Server: Memory Manager: Granted Workspace Memory (KB)
        Specifies the total amount of memory currently granted to executing processes, such as hash, sort, bulk copy, and index creation operations.
        Requirement3: Process: working Set
        Each time a process is created, it reserves the minimum working set size for the process. The virtual memory manager attempts to keep enough memory for the minimum working set resident when the process is active, but keeps no more than the maximum size.

        NEW QUESTION 8
        Note: this question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in the series. Information and details provided in a question apply only to that question.
        You are developing an application to track customer sales.
        You need to create a database object that meets the following requirements:
        Launch when table data is modified.
        Evaluate the state a table before and after a data modification and take action based on the difference. Prevent malicious or incorrect table data operations.
        Prevent changes that violate referential integrity by cancelling the attempted data modification.
        Run managed code packaged in an assembly that is created in the Microsoft.NET Framework and located into Microsoft SQL Server.
        What should you create?

        • A. extended procedure
        • B. CLR procedure
        • C. user-defined procedure
        • D. DDL trigger
        • E. scalar-valued function
        • F. table-valued function

        Answer: B

        Explanation: You can create a database object inside SQL Server that is programmed in an assembly created in the Microsoft .NET Framework common language runtime (CLR). Database objects that can leverage the rich programming model provided by the CLR include DML triggers, DDL triggers, stored procedures, functions, aggregate functions, and types.
        Creating a CLR trigger (DML or DDL) in SQL Server involves the following steps:
        Define the trigger as a class in a .NETFramework-supported language. For more information about how to program triggers in the CLR, see CLR Triggers. Then, compile the class to build an assembly in the .NET Framework using the appropriate language compiler.
        Register the assembly in SQL Server using the CREATE ASSEMBLY statement. For more information about
        assemblies in SQL Server, see Assemblies (Database Engine). Create the trigger that references the registered assembly.

        You have a Microsoft SQL Server database named DB1 that contains the following tables: You frequently run the following queries:
        70-762 dumps exhibit
        There are no foreign key relationships between TBL1 and TBL2.
        You need to minimize the amount of time required for the two queries to return records from the tables. What should you do?

        • A. Create clustered indexes on TBL1 and TBL2.
        • B. Create a clustered index on TBL1 Create a nonclustered index on tbl2 and add the most frequently queried columns as included columns.
        • C. Create a nonclustered index on tbl2 only.
        • D. Create unique constraints on both TBL1 and TBL2. Create a partitioned view that combines columns from TBL1 and TBL2.
        • E. Drop existing indexes on TBL1 and then create a clustered columnstore inde
        • F. Create a nonclustered columnstore index on TBL1. Create a nonclustered index on TBL2.
        • G. Drop existing indexes on TBL1 and then create a cluwered columnstore inde
        • H. Create a nonclustered columnstore index on TBL1. Make no changes to TBL2.
        • I. Create check constraints on both TBL1 and tbl2. Create a partitioned view that combines columns from TBL1 and tbl2.
        • J. Create an indexed view that combines columns from TBL1 and TBL2.

        Answer: F

        NEW QUESTION 10
        Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
        You have a database that contains a table named Employees. The table stored information about the employees of your company.
        You need to implement the following auditing rules for the Employees table:
        - Record any changes that are made to the data in the Employees table.
        - Customize the data recorded by the audit operations.
        Solution: You implement a stored procedure on the Employees table. Does the solution meet the goal?

        • A. Yes
        • B. No

        Answer: B

        Explanation: We should use table-valued functions, not procedures, to customize the recorded change data. References: https://msdn.microsoft.com/en-us/library/cc645858.aspx

        NEW QUESTION 11
        Note: this question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in the series. Information and details provided in a question apply only to that question.
        You are developing an application to track customer sales.
        You need to create a database object that meets the following requirements:
        - Return a value of 0 if data is inserted successfully into the Customers table.
        - Return a value of 1 if data is not inserted successfully into the Customers table.
        - Support logic that is written by using managed code.
        - Support TRY…CATCH error handling.
        What should you create?

        • A. extended procedure
        • B. CLR procedure
        • C. user-defined procedure
        • D. DML trigger
        • E. DDL trigger
        • F. scalar-valued function
        • G. table-valued function

        Answer: B

        Explanation: DML triggers is a special type of stored procedure that automatically takes effect when a data manipulation language (DML) event takes place that affects the table or view defined in the trigger. DML events include INSERT, UPDATE, or DELETE statements. DML triggers can be used to enforce business rules and data integrity, query other tables, and include complex Transact-SQL statements.
        A CLR trigger is a type of DDL trigger. A CLR Trigger can be either an AFTER or INSTEAD OF trigger. A CLR trigger can also be a DDL trigger. Instead of executing a Transact-SQL stored procedure, a CLR trigger executes one or more methods written in managed code that are members of an assembly created in the .NET Framework and uploaded in SQL Server.

        NEW QUESTION 12
        You have a database that contains both disk-based and memory-optimized tables.
        You need to create two modules. The modules must meet the requirements described in the following table.
        70-762 dumps exhibit
        Which programming object should you use for each module? To answer, select the appropriate object types in the answer area.
        70-762 dumps exhibit

          Answer:

          Explanation: Returning Data by Using OUTPUT Parameters
          If you specify the OUTPUT keyword for a parameter in the procedure definition, the stored procedure can return the current value of the parameter to the calling program when the stored procedure exits.
          SQL Server stored procedures, views and functions are able to use the WITH ENCRYPTION option to disguise the contents of a particular procedure or function from discovery.
          Native Compilation of Tables and Stored Procedures
          In-Memory OLTP introduces the concept of native compilation. SQL Server can natively compile stored procedures that access memory-optimized tables. SQL Server is also able to natively compile
          memory-optimized tables. Native compilation allows faster data access and more efficient query execution than interpreted (traditional) Transact-SQL. Native compilation of tables and stored procedures produce DLLs.

          NEW QUESTION 13
          Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
          You have a database that contains a table named Employees. The table stores information about the employees of your company.
          You need to implement the following auditing rules for the Employees table:
          - Record any changes that are made to the data in the Employees table.
          - Customize the data recorded by the audit operations.
          Solution: You implement a user-defined function on the Employees table. Does the solution meet the goal?

          • A. Yes
          • B. No

          Answer: A

          Explanation: SQL Server 2016 provides two features that track changes to data in a database: change data capture and change tracking. These features enable applications to determine the DML changes (insert, update, and delete operations) that were made to user tables in a database.
          Change data is made available to change data capture consumers through table-valued functions (TVFs). References: https://msdn.microsoft.com/en-us/library/cc645858.aspx

          NEW QUESTION 14
          You run the following Transact-SQL following statement:
          70-762 dumps exhibit
          Customer records may be inserted individually or in bulk from an application. You observe that the application attempts to insert duplicate records.
          You must ensure that duplicate records are not inserted and bulk insert operations continue without notifications.
          Which Transact-SQL statement should you run?

          • A. CREATE UNIQUE NONCLUSTERED INDEX IX_Customer_Code ON Customer (Code) WITH(ONLINE = OFF)
          • B. CREATE UNIQUE INDEX IX_CUSTOMER_Code O Customer (Code) WITH (IGNORE_DUP_KEY= ON)
          • C. CREATE UNIQUE INDEX IX Customer Code ON Customer (Code) WITH (IGNORE DUP KEY=OFF)
          • D. CREATE UNIQUE NONCLUSTERED INDEX IX_Customer_Code ON Customer (Code)
          • E. CREATE UNIQUE NONCLUSTERED INDEX IX_Customer_Code ON Customer (Code) WITH (ONLINE = ON)

          Answer: B

          Explanation: IGNORE_DUP_KEY = { ON | OFF } specifies the error response when an insert operation attempts to insert duplicate key values into a unique index. The IGNORE_DUP_KEY option applies only to insert operations after the index is created or rebuilt. The option has no effect when executing CREATE INDEX, ALTER INDEX, or UPDATE. The default is OFF.
