QUESTION 41
You have a server named Serverl that is hosted in an Azure virtual machine.
Server1 contains the following:

– One instance of SQL Server 2016 Enterprise
– 10 databases
– 500 stored procedures

You have a database named Databasel that is hosted on Server1.
Database1 contains 100 queries that are executed dynamically from web applications.
You plan to remove data from the procedure cache on Database1.
You have the following requirements:

– Changes to Database1 must not affect other databases that are hosted on Server1
– Changes to Database1 must not affect the performance of queries that are stored in other databases.
– The solution must minimize administrative effort.

You need to remove the data from the procedure cache as quickly as possible.
What should you do?

A.    Run DBCC FREEPROCCACHE.
B.    Run ALTER DATABASE SCOPED CONFIGURATION CLEAR PROCEDURE CACHE in the context of Database 1.
C.     Run DBCC DROPCLEANBUFFERS.
D.     Write a script that iterates through each stored procedure definition and add WITH RECOMPILE to the definition.

Answer: B
Explanation:
You should run ALTER DATABASE SCOPED CONFIGURATION CLEAR PROCEDURE CACHE in the context of Database! This statement lets you change the settings of a database without affecting other databases that are installed on the instance of SQL Server 2016.
You should not run DBCC FREEPROCCACHE. DBCC FREEPROCCACHE would clean the entire plan cache and would affect all databases. It is possible to remove a single plan from the cache by using the plan_handle argument to DBCC FREEPROCCACHE, but you would have to identify all plans that are related to Databasel, which requires a lot more administrative effort.
You should not run DBCC DROPCLEANBUFFERS. DBCC DROPCLEANBUFFERS will remove the clean pages from the buffer cache. Columnstore pages are removed from the columnstore cache.
You should not write a script that will iterate through each stored procedure definition and add WITH RECOMPILE to the definition. Each time the procedure is called, it will be recompiled, and this might degrade the server’s performance. This approach would require additional administrative effort to produce the script. In addition, some calls are made from the web application and the script would not have any control over these calls. In earlier versions of SQL Server, prior to the availability of the ALTER DATABASE statement, this option would have been the way to avoid affecting other databases.

QUESTION 42
You are designing a Windows Azure SQL Database for an order fulfillment system.
You create a table named Sales.Orders with the following script.

Each order is tracked by using one of the following statuses:

– Fulfilled
– Shipped
– Ordered
– Received

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.

More than one answer choice may achieve the goal. Select the BEST answer.

A.    To the Sales.Orders table, add three columns named Status, PreviousStatus and ChangeDate.
Update rows as the order status changes.
B.    Create 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.
C.    Implement change data capture on the Sales.Orders table.
D.    To 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.

Answer: B

QUESTION 43
You are using dynamic management views to monitor an SQL Server server named SQL1.
A database administrator named Dba1 must monitor the health of SQL1.
You need to ensure that Dba1 can access dynamic management views for SQL1.
The solution must use the principle of least privilege.
Which permissions should you assign to Dba1?

A.    VIEW ANY DEFINITION
B.    VIEW SERVER STATE
C.    VIEW DEFINITION
D.    CONTROL SERVER

Answer: B
Explanation:
To query a dynamic management view or function requires SELECT permission on object and VIEW SERVER STATE or VIEW DATABASE STATE permission.

QUESTION 44
You are the administrator for a SQL Server 2016 instance that stores the data for an online transaction processing sales system.
The company takes full backups every week; differential backups on the days with no full backups; and hourly transaction backups.
These backups are stored on a backup server in the company’s data center.
Every week, the company places the full backup on a tape and sends it to a third-party backup storage system.
The company is worried that a disaster might occur that could destroy their computer center and cause them to lose orders.
You need to determine the best method for providing the smallest amount of data loss and downtime without leasing or purchasing additional physical locations.
What should you do? More than one answer choice may achieve the goal. Select the BEST answer.

A.    Set up SQL Server Always On with a SQL Azure database as a replica.
B.    Set up SQL Server Always On by using a SQL Server on a Windows Azure Virtual Machine.
C.    Put the differential backup on tape and send it to the third-party backup storage system.
D.    Use the Microsoft SQL Server Backup to Microsoft Windows Azure Tool to direct all backups
to a different geographical location.

Answer: D

QUESTION 45
You have a SQL Server 2016 database named DB1.
You plan to import a large number of records from a SQL Azure database to DB1.
You need to recommend a solution to minimize the amount of space used in the transaction log during the import operation.
What should you include in the recommendation?

A.    The bulk-logged recovery model
B.    The full recovery model
C.    A new partitioned table
D.    A new log file
E.    A new file group

Answer: A
Explanation:
Compared to the full recovery model, which fully logs all transactions, the bulk-logged recovery model minimally logs bulk operations, although fully logging other transactions.
The bulk-logged recovery model protects against media failure and, for bulk operations, provides the best performance and least log space usage.
Note:
The bulk-logged recovery model is a special-purpose recovery model that should be used only intermittently to improve the performance of certain large-scale bulk operations, such as bulk imports of large amounts of data.

QUESTION 46
You administer a Microsoft SQL Server 2012 database.
Users report that an application that accesses the database displays an error, but the error does not provide meaningful information.
No entries are found in the SQL Server log or Windows event logs related to the error.
You need to identify the root cause of the issue by retrieving the error message.
What should you do?

A.    Create an Extended Events session by using the sqlserver.error_reported event.
B.    Create a SQL Profiler session to capture all ErrorLog and EventLog events.
C.    Flag all stored procedures for recompilation by using sp_recompile.
D.    Execute sp_who.

Answer: A
Explanation:
Event sqlserver.error_reported: This event gets fired every time that an error happens in the server.
https://blogs.msdn.microsoft.com/extended_events/2010/04/14/introduction-to-extended-events/

QUESTION 47
You administer a Microsoft SQL Server 2012 server.
One of the databases on the server supports a highly active OLTP application.
Users report abnormally long wait times when they submit data into the application.
You need to identify which queries are taking longer than 1 second to run over an extended period of time.
What should you do?

A.    use SQL Profiler to trace all queries that are processing on the server.
Filter queries that have a Duration value of more than 1,000.
B.    Use sp_configure to set a value for blocked process threshold.
Create an extended event session.
C.    Use the Job Activity monitor to review all processes that are actively running.
Review the Job History to find out the duration of each step.
D.    Run the sp_who command from a query window.
E.    Run the DBCC TRACEON 1222 command from a query window and review the SQL Server event log.

Answer: A
Explanation:
Incorrect Answers:
E: DBCC TRACEON 1222 is used to detect deadlocks, not to detect long running queries.

QUESTION 48
You administer a Microsoft SQL Server 2012 database.
You need to ensure that the size of the transaction log file does not exceed 2 GB.
What should you do?

A.    Execute sp_configure ‘max log size’, 2G.
B.    use the ALTER DATABASE…SET LOGFILE command along with the maxsize parameter.
C.    In SQL Server Management Studio, right-click the instance and select Database Settings. Set the maximum size of the file for the transaction log.
D.    In SQL Server Management Studio, right-click the database, select Properties, and then click Files.
Open the Transaction log Autogrowth window and set the maximum size of the file.

Answer: B
Explanation:
You can use the ALTER DATABASE (Transact-SQL) statement to manage the growth of a transaction log file
To control the maximum the size of a log file in KB, MB, GB, and TB units or to set growth to UNLIMITED, use the MAXSIZE option.
However, there is no SET LOGFILE subcommand.

You need to ensure that the SQL Server instance can use all nodes of the cluster.
What should you do?

A.    Run the New SQL Server stand-alone installation Wizard on Node C.
B.    Run the Add Node to SQL Server Failover Cluster Wizard on Node C.
C.    Use Node B to install SQL Server on Node C.
D.    Use Node A to install SQL Server on Node C.

Answer: B
Explanation:
To add a node to an existing SQL Server failover cluster, you must run SQL Server Setup on the node that is to be added to the SQL Server failover cluster instance.
Do not run Setup on the active node.
The Installation Wizard will launch the SQL Server Installation Center. To add a node to an existing failover cluster instance, click Installation in the left-hand pane.

QUESTION 71
You are developing a Microsoft SQL Server database.
You create a view that performs the following tasks:
Joins 10 tables that contain up to 400,000 records each.
Performs aggregations on 4 fields.
The view is frequently used in several detailed reports.
You need to improve the performance of the reports. What should you do?

A.    Convert the view into a table-valued function
B.    Convert the view into an indexed view
C.    Convert the view into a stored procedure and retrieve the result from the stored procedure into a temporary table
D.    Convert the view into a Common Table Expression (CTE)

Answer: B
Explanation:
The first index created on a view must be a unique clustered index. After the unique clustered index has been created, you can create more nonclustered indexes. Creating a unique clustered index on a view improves query performance because the view is stored in the database in the same way a table with a clustered index is stored. The query optimizer may use indexed views to speed up the query execution. The view does not have to be referenced in the query for the optimizer to consider that view for a substitution.

QUESTION 72
Is the following statement TRUE or FALSE?
JSON is not a built-in data type in SQL Server 2016, and SQL Server 2016 does not have custom JSON indexes?

A.    TRUE
B.    FALSE

Answer: A

QUESTION 73
The !> operator is a comparison operator that compares two expressions.
However, if ANSI_NULLS is set to ON and one of the operands is NULL, what will the result be?

expression !> expression (NULL)

A.    FALSE
B.    0
C.    TRUE
D.    NULL

Answer: D
Explanation:
If either or both operands are NULL and SET ANSI_NULLS is set to ON, the result is NULL. If SET ANSI_NULLS is set to OFF, the result is FALSE if one of the operands is NULL, and TRUE if both operands are NULL.

QUESTION 74
You are developing a SQL Server database that contains a heap named OrdersArchive.
You write the following Transact-SQL query:

INSERT INTO OrdersArchive
SELECT * FROM CompletedOrders

You need to optimize transaction logging and locking for the statement.
Which table hint should you use?

A.    HOLDLOCK
B.    TABLOCK
C.    XLOCK
D.    ROWLOCK

Answer: B
Explanation:
Table hints override the default behavior of the query optimizer for the duration of the data manipulation language (DML) statement by specifying a locking method, one or more indexes, a query-processing operation such as a table scan or index seek, or other options. Table hints are specified in the FROM clause of the DML statement and affect only the table or view referenced in that clause.
When importing data into a heap by using the INSERT INTO SELECT FROM statement, you can enable optimized logging and locking for the statement by specifying the TABLOCK hint for the target table. In addition, the recovery model of the database must be set to simple or bulk- logged.

QUESTION 75
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section. You will NOT be able to return to it. As a result, these questions will not appear in the review screen.

A database has two tables as shown in the following database diagram:

You need to list all provinces that have at least two large cities.
A large city is defined as having a population of at least one million residents.
The query must return the following columns:

Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?

A.    Yes
B.    No

Answer: A
Explanation:
The requirement to list all provinces that have at least two large cities is meet by the WHERE CitySummary.LargeCityCount >=2 clause.
CROSS APPLY will work fine here.
Note:
The APPLY operator allows you to invoke a table-valued function for each row returned by an outer table expression of a query. The table-valued function acts as the right input and the outer table expression acts as the left input. The right input is evaluated for each row from the left input and the rows produced are combined for the final output. The list of columns produced by the APPLY operator is the set of columns in the left input followed by the list of columns returned by the right input.
There are two forms of APPLY: CROSS APPLY and OUTER APPLY. CROSS APPLY returns only rows from the outer table that produce a result set from the table-valued function. OUTER APPLY returns both rows that produce a result set, and rows that do not, with NULL values in the columns produced by the table-valued function.
