NEW QUESTION 2
Background
You have a database named HR1 that includes a table named Employee.
You have several read-only, historical reports that contain regularly changing totals. The reports use multiple queries to estimate payroll expenses. The queries run concurrently. Users report that the payroll estimate reports do not always run. You must monitor the database to identify issues that prevent the reports from running.
You plan to deploy the application to a database server that supports other applications. You must minimize the amount of storage that the database requires.
Employee Table
You use the following Transact-SQL statements to create, configure, and populate the Employee table:

Application
You have an application that updates the Employees table. The application calls the following stored procedures simultaneously and asynchronously:
- UspA: This stored procedure updates only the EmployeeStatus column.
- UspB: This stored procedure updates only the EmployeePayRate column.
The application uses views to control access to data. Views must meet the following requirements:
- Allow user access to all columns in the tables that the view accesses.
- Restrict updates to only the rows that the view returns. Exhibit

You are analyzing the performance of the database environment. You discover that locks that are held for a long period of time as the reports are generated.
You need to generate the reports more quickly. The database must not use additional resources. What should you do?

• A. Update the transaction level of the report query session to READPAST.

NEW QUESTION 5
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:

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 create a stored procedure named spDeleteCategory to delete records in the database. The stored procedure must meet the following requirements:
* Delete records in both the BlogEntry and BlogCategory tables where CategoryId equals parameter
@CategoryId.
* Avoid locking the entire table when deleting records from the BlogCategory table.
* If an error occurs during a delete operation on either table, all changes must be rolled back, otherwise all changes should be committed.
How should you complete the procedure? To answer, select the appropriate Transact-SQL segments in the answer area.

Answer:

Explanation: Box 1: SET TRANSACTION ISOLATION LEVEL READ COMMITTED
You can minimize locking contention while protecting transactions from dirty reads of uncommitted data modifications by using either of the following:
* The READ COMMITTED isolation level with the READ_COMMITTED_SNAPSHOT database option set ON.
* The SNAPSHOT isolation level.
With ROWLOCK we should use READ COMMITTED Box 2: ROWLOCK
Requirement: Avoid locking the entire table when deleting records from the BlogCategory table
ROWLOCK specifies that row locks are taken when page or table locks are ordinarily taken. When specified in transactions operating at the SNAPSHOT isolation level, row locks are not taken unless ROWLOCK is combined with other table hints that require locks, such as UPDLOCK and HOLDLOCK.
Box 3: COMMIT
Box 4: ROLLBACK

NEW QUESTION 6
You are maintaining statistics for a database table named tblTransaction. The table contains more than 10 million records.
You need to create a stored procedure that meets the following requirements:
- On weekdays, update statistics for a sample of the total number of records in the table.
- On weekends, update statistics by sampling all rows in the table. A maintenance task will call this stored procedure daily.
How should you complete the stored procedure? To answer, select the appropriate Transact-SQL segments in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation: Box 1: UPDATE STATISTICS Box 2: SAMPLE 20 PERCENT
UPDATE STATISTICS tablenameSAMPLE number { PERCENT | ROWS }
Specifies the approximate percentage or number of rows in the table or indexed view for the query optimizer to use when it updates statistics. For PERCENT, number can be from 0 through 100 and for ROWS, number can be from0 to the total number of rows.
Box 3: UPDATE STATISTICS Box 4: WITH FULLSCAN
FULLSCAN computes statistics by scanning all rows in the table or indexed view. FULLSCAN and SAMPLE 100 PERCENT have the same results. FULLSCAN cannot be used with the SAMPLE option.

You need to create the Sales Order table
How should you complete the table definition? To answer? select the appropriate Transact-SQL segments in the answer area.

Answer:

Explanation: Box 1: NONCLUSTERED HASHWITH (BUCKET_COUNT = 10000000)
Hash index is preferable over a nonclustered index when queries test the indexed columns by use of a WHERE clause with an exact equality on all index key columns. We should use a bucket count of 10 million.
Box 2: SCHEMA_ONLY
Durability: The value of SCHEMA_AND_DATA indicates that the table is durable, meaning that changes are persisted on disk and survive restart or failover. SCHEMA_AND_DATA is the default value.
The value of SCHEMA_ONLY indicates that the table is non-durable. The table schema is persisted but any data updates are not persisted upon a restart or failover of the database. DURABILITY=SCHEMA_ONLY is only allowed with MEMORY_OPTIMIZED=ON.

NEW QUESTION 10
You have a database that contains three encrypted store procedures named dbo.Proc1, dbo.Proc2 and dbo.Proc3. The stored procedures include INSERT, UPDATE, DELETE and BACKUP DATABASE statements.
You have the following requirements:
* You must run all the stored procedures within the same transaction.
* You must automatically start a transaction when stored procedures include DML statements.
* You must not automatically start a transaction when stored procedures include DDL statements. You need to run all three stored procedures.
Which four Transact-SQL segments should you use to develop the solution? To answer, move the appropriate Transact-SQL segments to the answer area and arrange then in the correct order.

Answer:

Explanation: Note:
Implicit transaction mode remains in effect until the connection executes a SET IMPLICIT_TRANSACTIONS OFF statement, which returns the connection to autocommit mode. In autocommit mode, all individual statements are committed if they complete successfully.
When a connection is in implicit transaction mode and the connection is not currently in a transaction, executing any of the following statements starts a transaction:
Note 2: XACT_STATE returns the following values.
1 The current request has an active user transaction. The request can perform any actions, including writing data and committing the transaction. The transaction is committable.
-1 The current request has an active user transaction, but an error has occurred that has caused the transaction to be classified as an uncommittable transaction. The transaction is uncommittable and should be rolled back.
0 There is no active user transaction for the current request. A commit or rollback operation would generate an error.

NEW QUESTION 12
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. DML 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.

NEW QUESTION 13
You are developing queries and stored procedures to support a line-of-business application. You need to use the appropriate isolation level based on the scenario.
Which isolation levels should you implement? To answer, select the appropriate isolation level for each scenario in the answer area. Each isolation level may be used only once.
NOTE: Each correct selection is worth one point.

Answer:

Explanation: Box 1: READ UNCOMMITTED
Transactions running at the READ UNCOMMITTED level do not issue shared locks to prevent other transactions from modifying data read by the current transaction. READ UNCOMMITTED transactions are also not blocked by exclusive locks that would prevent the current transaction from reading rows that have been modified but not committed by other transactions. When this option is set, it is possible to read uncommitted modifications, which are called dirty reads. Values in the data can be changed and rows can appear or disappear in the data set before the end of the transaction.
Box 2: READ COMMITTED
READ COMMITTED specifies that statements cannot read data that has been modified but not committed by other transactions.
SERIALIZABLE specifies that statements cannot read data that has been modified but not yet committed by other transactions.
Box 3: REPEATABLE READ
REPEATABLE READ specifies that statements cannot read data that has been modified but not yet committed by other transactions and that no other transactions can modify data that has been read by the current transaction until the current transaction completes.
Box 4: SNAPSHOT
If READ_COMMITTED_SNAPSHOT is set to ON, the Database Engine uses row versioning to present each statement with a transactionally consistent snapshot of the data as it existed at the start of the statement.

How should you complete the Transact-SQL statements? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segment 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: More than one combination of answer choices is correct. You will receive credit for any of the correct combinations you select.

Answer:

Explanation: Box 1: Sys.dm_exec_connections
Sys.dm_exec_connections returns information about the connections established to this instance of SQL Server and the details of each connection. Returns server wide connection information for SQL Server. Returns current database connection information for SQL Database.
Box 2: sys.dm_exec_sessions
sys.dm_exec_sessions returns one row per authenticated session on SQL Server. sys.dm_exec_sessions is a server-scope view that shows information about all active user connections and internal tasks.
Box 3: GRANT VIEW DATABASE STATE To User1
SQL Database: Requires VIEW DATABASE STATE to see all connections to the current database. VIEW DATABASE STATE cannot be granted in the master database.

Each question is independent of the other question in the series. Information and details provided in a question apply only to that question.
You have a reporting database that includes a non-partitioned fact table named Fact_Sales. The table is persisted on disk.
Users report that their queries take a long time to complete. The system administrator reports that the table takes too much space in the database. You observe that there are no indexes defined on the table, and many columns have repeating values.
You need to create the most efficient index on the table, minimize disk storage and improve reporting query performance.
What should you do?

• A. Create a clustered indexon the table.
• B. Create a nonclustered index on the table.
• C. Create a nonclustered filtered index on the table.
• D. Create a clustered columnstore index on the table.
• E. Create a nonclustered columnstore index on the table.
• F. Create a hash index on thetable.

Answer: D

Explanation: The columnstore index is the standard for storing and querying large data warehousing fact tables. It uses column-based data storage and query processing to achieve up to 10x query performance gains in your data warehouse over traditional row-oriented storage, and up to 10x data compression over the uncompressed data size.
A clustered columnstore index is the physical storage for the entire table.
