NEW QUESTION 1
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. scalar-valued function
  • F. table-valued function

Answer: D

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.

NEW QUESTION 2
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 2021 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 3
You have multiple stored procedures inside a transaction.
You need to ensure that all the data modified by the transaction is rolled back if a stored procedure causes a deadlock or times out.
What should you do?

  • A. Use the NOLOCK option.
  • B. Execute the DBCC UPDATEUSAGE statement.
  • C. Use the max worker threads Option.
  • D. Use a table-valued parameter.
  • E. Set SET ALLOW SNAPSHOT ISOLATION to ON,
  • F. Set SET XACT ABORT to ON.
  • G. Execute the alter table T1 set (lock escalation = auto); statement.
  • H. Use the output parameters.

Answer: B

NEW QUESTION 4

    NEW QUESTION 5
    You need to implement triggers to automate responses to the following events:
    SQL Server logons
    Database schema changes
    Database updates
    Which trigger types should you use? To answer, drag the appropriate trigger types to the appropriate scenarios. Each trigger type may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
    NOTE: Each correct selection is worth one point.
    70-762 dumps exhibit

      Answer:

      Explanation: Box 1: LOGON
      Logon triggers fire stored procedures in response to a LOGON event. This event is raised when a user session is established with an instance of SQL Server.
      Box 2: INSTEAD OF INSERT
      An "INSTEAD of trigger" is executed instead of the original operation, and not combining with the operation. INSTEAD OF triggers override the standard actions of the triggering statement. It can be used to bypass the statement and execute a whole different statement, or just help us check and examine the data before the action is done.
      Box 3: DDL
      DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database
      Note:
      You can write triggers that fire whenever one of the following operations occurs:
      DML statements (INSERT, UPDATE, DELETE) on a particular table or view, issued by any user
      DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database
      Database events, such as logon/logoff, errors, or startup/shutdown, also issued either by a particular schema/user or by any schema/user in the database

      NEW QUESTION 6
      You have a reporting application that uses a table named Table1. You deploy a new batch update process to perform updates to Table1.
      The environment is configured with the following properties:
      The database is configured with the default isolation setting.
      The application and process use the default transaction handling.
      You observe the application cannot access any rows that are in use by the process.
      You have the following requirements:
      Ensure the application is not blocked by the process.
      Ensure the application has a consistent view of the data
      Ensure the application does not read dirty data.
      You need to resolve the issue and meet the requirements with the least amount of administrative effort. What should you do?

      • A. Enable the database for the ALLOW_SNAPSHOT_ISOLATION isolation leve
      • B. Modify the applicationfor the SERIALIZABLE isolation level.
      • C. Enable the database for the READ_COMITTED_SNAPSHOT isolation level.
      • D. Enable the application for the WITH (NOLOCK) hint.
      • E. Enable the database for the ALLOW_SNAPSHOT_ISOLATION isolation leve
      • F. Modify the application and the update process for the SNAPSHOT isolation level.

      Answer: B

      Explanation: Snapshot isolation must be enabled by setting the ALLOW_SNAPSHOT_ISOLATION ON database option before it is used in transactions. This activates the mechanism for storing row versions in the temporary database (tempdb).
      READ COMMITTED is the default isolation level for SQL Server. It prevents dirty reads by specifying that statements cannot read data values that have been modified but not yet committed by other transactions. Other transactions can still modify, insert, or delete data between executions of individual statements within the current transaction, resulting in non-repeatable reads, or "phantom" data.

      NEW QUESTION 7
      Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
      You have a database that contains the following tables: BlogCategory, BlogEntry, ProductReview, Product, and SalesPerson. The tables were created using the following Transact SQL statements:
      70-762 dumps exhibit
      You must modify the ProductReview Table to meet the following requirements:
      * The table must reference the ProductID column in the Product table
      * Existing records in the ProductReview table must not be validated with the Product table.
      * Deleting records in the Product table must not be allowed if records are referenced by the ProductReview table.
      * Changes to records in the Product table must propagate to the ProductReview table.
      You also have the following database tables: Order, ProductTypes, and SalesHistory, The transact-SQL statements for these tables are not available.
      You must modify the Orders table to meet the following requirements:
      * Create new rows in the table without granting INSERT permissions to the table.
      * Notify the sales person who places an order whether or not the order was completed.
      You must add the following constraints to the SalesHistory table:
      * a constraint on the SaleID column that allows the field to be used as a record identifier
      * a constant that uses the ProductID column to reference the Product column of the ProductTypes table
      * a constraint on the CategoryID column that allows one row with a null value in the column
      * a constraint that limits the SalePrice column to values greater than four
      Finance department users must be able to retrieve data from the SalesHistory table for sales persons where the value of the SalesYTD column is above a certain threshold.
      You plan to create a memory-optimized table named SalesOrder. The table must meet the following requirements:
      * The table must hold 10 million unique sales orders.
      * The table must use checkpoints to minimize I/O operations and must not use transaction logging.
      * Data loss is acceptable.
      Performance for queries against the SalesOrder table that use Where clauses with exact equality operations must be optimized.
      You need to enable referential integrity for the ProductReview table.
      How should you complete the relevant Transact-SQL statement? To answer? select the appropriate Transact-SQL segments in the answer area.
      Select two alternatives.

      • A. For the first selection select: WITH CHECK
      • B. For the first selection select: WITH NOCHECK
      • C. For the second selection select: ON DELETE NO ACTION ON UPDATE CASCADE
      • D. For the second selection select: ON DELETE CASCADE ON UPDATE CASCADE
      • E. For the second selection select: ON DELETE NO ACTION ON UPDATE NO ACTION
      • F. For the second selection select: ON DELETE CASCADE ON UPDATE NO ACTION

      Answer: BC

      Explanation: B: We should use WITH NOCHECK as existing records in the ProductReview table must not be validated with the Product table.
      C: Deletes should not be allowed, so we use ON DELETE NO ACTION. Updates should be allowed, so we use ON DELETE NO CASCADE
      NO ACTION: the Database Engine raises an error, and the update action on the row in the parent table is rolled back.
      CASCADE: corresponding rows are updated in the referencing table when that row is updated in the parent table.
      Note: ON DELETE { NO ACTION | CASCADE | SET NULL | SET DEFAULT }
      Specifies what action happens to rows in the table that is altered, if those rows have a referential relationship and the referenced row is deleted from the parent table. The default is NO ACTION.
      ON UPDATE { NO ACTION | CASCADE | SET NULL | SET DEFAULT }
      Specifies what action happens to rows in the table altered when those rows have a referential relationship and the referenced row is updated in the parent table. The default is NO ACTION.
      Note: You must modify the ProductReview Table to meet the following requirements:
      1. The table must reference the ProductID column in the Product table
      2. Existing records in the ProductReview table must not be validated with the Product table.
      3. Deleting records in the Product table must not be allowed if records are referenced by the ProductReview table.
      4. Changes to records in the Product table must propagate to the ProductReview table. References: https://msdn.microsoft.com/en-us/library/ms190273.aspx https://msdn.microsoft.com/en-us/library/ms188066.aspx

      NEW QUESTION 8
      Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
      You have a database named DB1 that contains the following tables: Customer, CustomerToAccountBridge, and CustomerDetails. The three tables are part of the Sales schema. The database also contains a schema named Website. You create the Customer table by running the following Transact-SQL statement:
      The value of the CustomerStatus column is equal to one for active customers. The value of the Account1Status and Account2Status columns are equal to one for active accounts. The following table displays selected columns and rows from the Customer table.
      70-762 dumps exhibit
      You plan to create a view named Website.Customer and a view named Sales.FemaleCustomers. Website.Customer must meet the following requirements:
      * Allow users access to the CustomerName and CustomerNumber columns for active customers.
      * Allow changes to the columns that the view references. Modified data must be visible through the view.
      * Prevent the view from being published as part of Microsoft SQL Server replication. Sales.Female.Customers must meet the following requirements:
      * Allow users access to the CustomerName, Address, City, State and PostalCode columns.
      * Prevent changes to the columns that the view references.
      * Only allow updates through the views that adhere to the view filter.
      You have the following stored procedures: spDeleteCustAcctRelationship and spUpdateCustomerSummary. The spUpdateCustomerSummary stored procedure was created by running the following Transacr-SQL statement:
      You run the uspUpdateCustomerSummary stored procedure to make changes to customer account summaries. Other stored procedures call the spDeleteCustAcctRelationship to delete records from the CustomerToAccountBridge table.
      When you start uspUpdateCustomerSummary, there are no active transactions. The procedure fails at line 09 due to a CHECK constraint violation on the TotalDepositAccountCount column.
      What is the impact of the stored procedure on the CustomerDetails table?

      • A. The value of the TotalAccountCount column decreased.
      • B. The value of the TotalDepositAccountCount column is not changed.
      • C. The statement that modifies TotalDepositAccountCount is excluded from the transaction.
      • D. The value of the TotalAccountCount column is not changed.

      Answer: D

            Answer:

            Explanation: Box 1:WITH SCHEMABINDING:
            SCHEMABINDING binds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the base table or tables cannot be modified in a way that would affect the view definition.
            Box 2:Box 2: WITH CHECK OPTION
            CHECK OPTION forces all data modification statements executed against the view to follow the criteria set within select_statement. When a row is modified through a view, the WITH CHECK OPTION makes sure the data remains visible through the view after the modification is committed.

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.
