QUESTION 1
You have an SQL Server 2016 server named SQL1. You are designing a performance monitoring solution.
You need to monitor the following events on SQL1:
A deadlock graph Missing column statistics CPU performance statistics A batch of completed Transact-SQL statements
Which two tools should you use? Each correct answer presents a complete solution.
A. dynamic management views
B. Database Engine Tuning Advisor
C. SQL Server Profiler
D. Activity Monitor
E. Data Profile Viewer
Correct Answer: BC
Explanation: B: Database Engine Tuning Advisor examines how queries are processed in the databases you specify.
When you run a Profiler Trace and feed it to the Database Engine Tuning Advisor, it also looks for missing column
statistics, and it can automatically create them for you.
C: Use SQL Server Profiler to identify the cause of a deadlock. A deadlock occurs when there is a cyclic dependency
between two or more threads, or processes, for some set of resources within SQL Server. Using SQL Server Profiler,
you can create a trace that records, replays, and displays deadlock events for analysis. Reference: Analyze Deadlocks
with SQL Server Profiler

QUESTION 3
You are troubleshooting an application that runs a query. The application frequently causes deadlocks.
You need to identify which transaction causes the deadlock.
What should you do?
More than one answer choice may achieve the goal. Select the BEST answer.
A. Query the sys.dm_exec_sessions dynamic management view.
B. Query the sys.dm_exec_requests dynamic management view.
C. Create a trace in SQL Server Profiler that contains the Deadlock graph event
D. Create an extended events session to capture deadlock information.
Correct Answer: D
Troubleshooting deadlocks
You have been receiving reports from users indicating that certain applications are returning deadlock errors. To
maximize the effectiveness of troubleshooting these problems, you decide to focus on the deadlocks that are hit most
frequently.
You create an Extended Events session that:
/ Configures deadlock event tracking for the session. / Specifies a target that aggregates based on an identifier for the
deadlock.
You run the Extended Events session, and after additional deadlocks are reported you are able to obtain aggregated
deadlock information, along with the complete XML deadlock graph for each source. Using this information you are able
to
pin point the most common deadlocks and start working on a solution.

QUESTION 14
You have a database named DB1.
You plan to create a stored procedure that will insert rows into three different tables. Each insert must use the same
identifying value for each table, but the value must increase from one invocation of the stored procedure to the next.
Occasionally, the identifying value must be reset to its initial value.
You need to design a mechanism to hold the identifying values for the stored procedure to use.
What should you do?
More than one answer choice may achieve the goal. Select the BEST answer.
A. Create a sequence object that holds the next value in the sequence. Retrieve the next value by using the stored
procedure. Reset the value by using an ALTER SEQUENCE statement as needed.
B. Create a sequence object that holds the next value in the sequence. Retrieve the next value by using the stored
procedure. Increment the sequence object to the next value by using an ALTER SEQUENCE statement. Reset the
value as needed by using a different ALTER SEQUENCE statement.
C. Create a fourth table that holds the next value in the sequence. At the end each transaction, update the value by
using the stored procedure. Reset the value as needed by using an UPDATE statement.
D. Create an identity column in each of the three tables. Use the same seed and the same increment for each table.
Insert new rows into the tables by using the stored procedure. Use the DBCC CHECKIDENT command to reset the
columns as needed.
Correct Answer: A
*
an application can obtain the next sequence number without inserting the row by calling the NEXT VALUE FOR
function.
*
ALTER SEQUENCE
Includes argument:
RESTART [ WITH ]
The next value that will be returned by the sequence object. If provided, the RESTART WITH value must be an integer
that is less than or equal to the maximum and greater than or equal to the minimum value of the sequence object. If the
WITH value is omitted, the sequence numbering restarts based on the original CREATE SEQUENCE options.
*
CREATE SEQUENCE
Creates a sequence object and specifies its properties. A sequence is a user-defined schema bound object that
generates a sequence of numeric values according to the specification with which the sequence was created. The
sequence of
numeric values is generated in an ascending or descending order at a defined interval and can be configured to restart
(cycle) when exhausted.

QUESTION 15
You have a database named DB1 that stores more than 700 gigabyte (GB) of data and serves millions of requests per
hour.
Queries on DB1 are taking longer than normal to complete.
You run the following Transact-SQL statement:
SELECT * FROM sys.database_query_store_options
You determine that the Query Store is in Read-Only mode.
You need to maximize the time that the Query Store is in Read-Write mode.
Which Transact-SQL statement should you run?
A. ALTER DATABASE DB1SET QUERY_STORE (QUERY_CAPTURE_MODE = ALL)
B. ALTER DATABASE DB1SET QUERY_STORE (MAX_STORAGE_SIZE_MB = 50)
C. ALTER DATABASE DB1SET QUERY_STORE (CLEANUP_POLICY = (STALE_QUERY_THRESHOLD_DAYS =
14));
D. ALTER DATABASE DB1SET QUERY_STORE (QUERY_CAPTURE_MODE = NONE)
Correct Answer: C
Stale Query Threshold (Days): Time-based cleanup policy that controls the retention period of persisted runtime
statistics and inactive queries. By default, Query Store is configured to keep the data for 30 days which may be
unnecessarily
long for your scenario.
Avoid keeping historical data that you do not plan to use. This will reduce changes to read- only status. The size of
Query Store data as well as the time to detect and mitigate the issue will be more predictable. Use Management Studio
or the
following script to configure time-based cleanup policy:
ALTER DATABASE [QueryStoreDB]
SET QUERY_STORE (CLEANUP_POLICY = (STALE_QUERY_THRESHOLD_DAYS =
14));
References:https://docs.microsoft.com/en-us/sql/relational-databases/performance/best- practice-with-the-query-store
QUESTION 16
Your network contains an Active Directory domain that has two groups named Group1 and Group2.
The domain contains two SQL Server instances named SQLDev and SQLProd. Each SQL Server instance has access
to various storage media.
The SQL Server instances have a database that contains a table named Table1.
Table1 contains a column named Column1. The value for Column1 can be either Value1 or Value2.
You need to recommend a solution to ensure that users in Group1 can retrieve only rows from Column1 that contain the
value of Value1.
What should you recommend?
A. A dynamic management view
B. Filegroups
C. Snapshot isolation
D. User-defined views
Correct Answer: D
A view is a virtual table whose contents are defined by a query. Like a table, a view consists of a set of named columns
and rows of data. Unless indexed, a view does not exist as a stored set of data values in a database. The rows and
columns of data come from tables referenced in the query defining the view and are produced dynamically when the
view is referenced.
A view acts as a filter on the underlying tables referenced in the view. http://msdn.microsoft.com/en-
us/library/ms190174.aspx
Incorrect:
Not A: Dynamic management views and functions return server state information that can be used to monitor the health
of a server instance, diagnose problems, and tune performance.

You need to identify the isolation level used by the query when a deadlock occurs.
What should you do?
More than one answer choice may achieve the goal. Select the BEST answer.
A. Query the sys.dm_exec_requests dynamic management view.
B. Create a trace in SQL Server Profiler that contains the Deadlock graph event.
C. Query the sys.dm_exec_sessions dynamic management view.
D. Enable trace flag 1222, and then view the SQL Server error log.
Correct Answer: C
* 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. Include the column:
transaction_isolation_level smallint Transaction isolation level of the session. 0 = Unspecified 1 = ReadUncomitted 2 =
ReadCommitted 3 = Repeatable 4 = Serializable 5 = Snapshot Is not nullable.

QUESTION 20
You have a database that stores information for a shipping company. You create a table named Customers by running
the following Transact-SQL statement. (Line numbers are included for reference only.)
You need to ensure that salespeople can view data only for the customers that are assigned to them. Which Transact-
SQL segment should you insert at line 07?
A. RETURNS varchar(20)WITH Schemabinding
B. RETURNS dbo.CustomersORDER BY @salesPerson
C. RETURNS tableORDER BY @salesPerson
D. RETURNS tableWITH Schemabinding
Correct Answer: D
The return value can either be a scalar (single) value or a table. SELECT 1 just selects a 1 for every row, of course.
What it\\’s used for in this case is testing whether any rows exist that match the criteria: if a row exists that matches the
WHERE clause, then it returns 1, otherwise it returns nothing. Specify the WITH SCHEMABINDING clause when you
are creating the function. This ensures that the objects referenced in the function definition cannot be modified unless
the function is also modified.

You need to configure a Microsoft SQL Server instance to ensure that a user named Mail1 can send mail by using
Database Mail.
Solution: You add the DatabaseMailUserRole to Mail1 in the msdb database.
Does the solution meet the goal?
A. Yes
B. No
Correct Answer: A
Database Mail is guarded by the database role DatabaseMailUserRole in the msdb database in order to prevent anyone
from sending arbitrary emails. Database users or roles must be created in the msdb database and must also be a
member of DatabaseMailUserRole in order to send emails with the exception of sysadmin who has all privileges.
Note: Database Mail was first introduced as a new feature in SQL Server 2005 and replaces the SQL Mail feature found
in previous versions.

QUESTION 24
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
Correct Answer: A
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.

A. AlwaysOn availability groups
B. Database mirroring
C. Log shipping
D. Failover Clustering
Correct Answer: A
The AlwaysOn Availability Groups feature is a high-availability and disaster-recovery solution that provides an enterprise-
level alternative to database mirroring. Introduced in SQL Server 2012, AlwaysOn Availability Groups maximizes the
availability of a set of user databases for an enterprise. An availability group supports a failover environment for a
discrete set of user databases, known as availability databases that fail over together.

QUESTION 27
You deploy a database by using SQL Server 2016. The database contains a table named Table1.
You need to recommend a solution to track all of the deletions executed on Table1. The solution must minimize the
amount of custom code required. What should you recommend?
A. Change data capture
B. Statistics
C. A trigger
D. Master Data Services
Correct Answer: A
Change data capture is designed to capture insert, update, and delete activity applied to SQL Server tables, and to
make the details of the changes available in an easily consumed relational format. The change tables used by change
data capture contain columns that mirror the column structure of a tracked source table, along with the metadata
needed to understand the changes that have occurred.

Correct Answer: C
*
Transparent Data Encryption (TDE) is a special case of encryption using a symmetric key. TDE encrypts an entire
database using that symmetric key called the database encryption key. The database encryption key is protected by
other keys or certificates which are protected either by the database master key or by an asymmetric key stored in an
EKM module.

SQL Server provides the following mechanisms for encryption: Transact-SQL functions Asymmetric keys Symmetric
keys Certificates Transparent Data Encryption

QUESTION 31
You create a stored procedure that retrieves all of the rows from a table named Table1.
You need to recommend a solution to ensure that all of the statements in the stored procedure can be executed if
another transaction is modifying rows in Table1 simultaneously. What should you recommend?
A. Snapshot isolation
B. A database snapshot
C. Filegroups
D. Indexes
Correct Answer: A
Once snapshot isolation is enabled, updated row versions for each transaction are maintained in tempdb. A unique
transaction sequence number identifies each transaction, and these unique numbers are recorded for each row version.
The transaction works with the most recent row versions having a sequence number before the sequence number of the
transaction. Newer row versions created after the transaction has begun are ignored by the transaction.

be correct for more than one question in the series. Each question is independent of the other questions in this series.
Information and details provided in a question apply only to that question.
You collect performance metrics on multiple Microsoft SQL Server instances and store the data in a single repository.
You need to examine disk usage, query statistics, and server activity without building custom counters.
What should you use?
A. Activity Monitor
B. Sp_who3 stored procedure
C. Object Explorer in the Microsoft SQL Server Management Studio (SSMS)
D. SQL Server Data Collector
E. SQL Server Data Tools (SSDT)
F. SQL Server Configuration Manager
Correct Answer: D
The data collector is a core component of the data collection platform for SQL Server 2017 and the tools that are
provided by SQL Server. The data collector provides one central point for data collection across your database servers
and applications. This collection point can obtain data from a variety of sources and is not limited to performance data
QUESTION 33
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 are a database administrator for a company that has an on-premises Microsoft SQL Server environment and
Microsoft Azure SQL Database instances. The environment hosts several customer databases, and each customer
uses a dedicated instance. The environments that you manage are shown in the following table.
You need to monitor WingDB and gather information for troubleshooting issues. What should you use?
A. sp_updatestats
B. sp_lock
C. sys.dm_os_waiting_tasks
D. sys.dm_tran_active_snapshot_database_transactions
Correct Answer: B
The sp_lock system stored procedure is packaged with SQL Server and will give you insight into the locks that are
happening on your system. This procedure returns much of its information from the syslock info in the master database,
which is a system table that contains information on all granted, converting, and waiting lock requests.
Note: sp_lock will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development
work, and plan to modify applications that currently use this feature. To obtain information about locks in the SQL
Server
Database Engine, use the sys.dm_tran_locks dynamic management view.
sys.dm_tran_locks returns information about currently active lock manager resources in SQL Server 2008and later.
Each row represents a currently active request to the lock manager for a lock that has been granted or is waiting to be
granted.

QUESTION 34
You administer a SQL Server 2016 instance.
Users report that the SQL Server has seemed slow today. A large database was being restored for much of the day,
which could be causing issues.
You want to write a query of the system views that will report the following:
Number of users that have a connection to the server Whether a user\\’s connection is active Whether any connections
are blocked What queries are being executed
Whether the database restore is still executing and, if it is, what percentage of the restore is complete.
Which system objects should you use in your query to best achieve this task?
A. sys.dm_exec_requests, sys.dm_exec_sessions, sys.objects
B. sys.dm_exec_sessions, sys.dm_exec_query_stats, sys.dm_exec_query_text,sys.objects
C. sys.sysprocesses, sys.dm_exec_query_text, sys.objects
D. sys.dm_exec_requests, sys.dm_exec_sessions, sys.dm_exec_query_text
Correct Answer: D
*
sys.dm_exec_requests
Returns information about each request that is executing within SQL Server.
*
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. This information includes client version, client program
name, client login time, login user, current session setting, and more.
*
sys.dm_exec_query_text
Returns the text of the SQL batch that is identified by the specified sql_handle.
sys.dm_exec_requests (Transact-SQL)
sys.dm_exec_sessions (Transact-SQL)
Incorrect:
*
sys.dm_exec_query_stats
Returns aggregate performance statistics for cached query plans in SQL Server. The view contains one row per query
statement within the cached plan, and the lifetime of the rows are tied to the plan itself.
*
sys.objects
Contains a row for each user-defined, schema-scoped object that is created within a database.
