    NEW QUESTION 101
    You have a database that contains a table named Employees. The table stores information about the employees of your company. You need to implement and enforce the following business rules:
    - Limit the values that are accepted by the Salary column.
    - Prevent salaries less than $15,000 and greater than $300,000 from being entered.
    - Determine valid values by using logical expressions.
    - Do not validate data integrity when running DELETE statements.
    Solution: You implement cascading referential integrity constraints on the table.
    Does the solution meet the goal?

    A. Yes
    B. No

    Answer: A

    NEW QUESTION 102
    You are developing a new application that uses a stored procedure. The stored procedure inserts thousands of records as a single batch into the Employees table. Users report that the application response time has worsened since the stored procedure was updated. You examine disk-related performance counters for the Microsoft SQL Server instance and observe several high values that include a disk performance issue. You examine wait statistics and observe an unusually high WRITELOG value. You need to improve the application response time.
    Solution: You update the application to use implicit transactions when connecting to the database.
    Does the solution meet the goal?

    A. Yes
    B. No

    Answer: B

    NEW QUESTION 103
    You are developing a new application that uses a stored procedure. The stored procedure inserts thousands of records as a single batch into the Employees table. Users report that the application response time has worsened since the stored procedure was updated. You examine disk-related performance counters for the Microsoft SQL Server instance and observe several high values that include a disk performance issue. You examine wait statistics and observe an unusually high WRITELOG value. You need to improve the application response time.
    Solution: You add a unique clustered index to the Employees table.
    Does the solution meet the goal?

    A. Yes
    B. No

    Answer: A

    NEW QUESTION 104
    You are experiencing performance issues with the database server. You need to evaluate schema locking issues, plan cache memory pressure points, and backup I/O problems. What should you create?

    A. a System Monitor report
    B. a sys.dm_tran_database_transaction dynamic management view query
    C. an Extended Events session that uses Query Editor
    D. an Activity Monitor session in Microsoft SQL Management Studio.

    Answer: D

    NEW QUESTION 105
    You have a database that is 130 GB and contains 500 million rows of data. Granular transactions and mass batch data imports change the database frequently throughout the day. Microsoft SQL Server Reporting Services (SSRS) uses the database to generate various reports by using several filters. You discover that some reports time out before they complete. You need to reduce the likelihood that the reports will time out.
    Solution: You create a file group for the indexes and a file group for the data files. You store the files for each file group on separate disks.
    Does this meet the goal?

    A. Yes
    B. No

    Answer: A
    Explanation:
    Consider creating two additional File Groups: Tables and Indexes. It is best not to put your stuff in PRIMARY as that is where SQL SERVER stores all of its data and meta-data about your objects. You create your Table and Clustered Index (as that is the data for the table) on [Tables] and all Non-Clustered indexes on [Indexes].

    NEW QUESTION 106
    You have a 3-TB database. The database server has 64 CPU cores. You plan to migrate the database to Microsoft Azure SQL Database. You need to select the service tier for the Azure SQL database. The solution must meet or exceed the current processing capacity.
    Solution: You select the Premium service tier.
    Does this meet the goal?

    A. Yes
    B. No

    Answer: A

    NEW QUESTION 107
    You suspect deadlocks on a database. Which two trace flags in the Microsoft SQL Server error log should you locate? (Each correct answer presents part of the solution. Choose two.)

    A. 1204
    B. 1211
    C. 1222
    D. 2528
    E. 3205

    Answer: AC
    Explanation:
    Trace flag 1204 returns the resources and types of locks participating in a deadlock and also the current command affected. Trace flag 1222 returns the resources and types of locks that are participating in a deadlock and also the current command affected, in an XML format that does not comply with any XSD schema.

    NEW QUESTION 108
    You are creating the following two stored procedures:
    - A natively-compiled stored procedure
    - An interpreted stored procedure that accesses both disk-based and memory-optimized tables
    Both stored procedures run within transactions. You need to ensure that cross-container transactions are possible. Which setting or option should you use?

    A. the SET TRANSACTION_READ_COMMITTED isolation level for the connection
    B. the SERIALIZABLE table hint on disk-based tables
    C. the SET MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT=ON option for the database
    D. the SET MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT=OFF option for the database

    Answer: C
    Explanation:
    Provide a supported isolation level for the memory-optimized table using a table hint, such as WITH (SNAPSHOT). The need for the WITH (SNAPSHOT) hint can be avoided through the use of the database option MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT. When this option is set to ON, access to a memory-optimized table under a lower isolation level is automatically elevated to SNAPSHOT isolation.
    Incorrect:
    Not B: Accessing memory optimized tables using the READ COMMITTED isolation level is supported only for autocommit transactions. It is not supported for explicit or implicit transactions.

    NEW QUESTION 109
    You are developing a database reporting solution for a table that contains 900 million rows and is 103 GB. The table is updated thousands of times a day, but data is not deleted. The SELECT statements vary in the number of columns used and the amount of rows retrieved. You need to reduce the amount of time it takes to retrieve data from the table. The must prevent data duplication. Which indexing strategy should you use?

    A. a nonclustered index for each column in the table
    B. a clustered columnstore index for the table
    C. a hash index for the table
    D. a clustered index for the table and nonclustered indexes for nonkey columns

    Answer: B

    NEW QUESTION 110
    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

    NEW QUESTION 111
    Drag and Drop
    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.)

    - AddressLine1
    - AddressLine2
    - City
    - StateProvinceID
    How should you complete the Transact-SQL statement? (To answer, select the appropriate Transact_SQL segments in the answer are.)
