QUESTION 11
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
Answer: B
Explanation:
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 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 this series. Information and details provided in a question apply only to that question.
You need to examine information about logins, CPU times, and Disk I/O on a particular database in Microsoft Azure.
What should you use?
A. Activity Monitor
B. Sp_who3
C. SQL Server Management Studio (SSMS) Object Explorer
D. SQL Server Data Collector
E. SQL Server Data Tools (SSDT)
F. SQL Server Configuration Manager
Answer: A
Explanation:
Activity Monitor displays information about SQL Server processes and how these processes affect the current instance of SQL Server. Activity Monitor is a tabbed document window with the following expandable and collapsible panes: Overview, Active User Tasks, Resource Waits, Data File I/O, and Recent Expensive Queries.
The Activity User Tasks Pane shows information for active user connections to the instance, including the following column:
* Login: The SQL Server login name under which the session is currently executing.
The Recent Expensive Queries Pane shows information about the most expensive queries that have been run on the instance over the last 30 seconds, including the following column:
* CPU (ms/sec): The rate of CPU use by the query

QUESTION 13
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 this series. Information and details provided in a question apply only to that question.
You have an on-premises server that runs Microsoft SQL Server 2016 Standard Edition.
You need to identify missing indexes.
What should you use?
A. Activity Monitor
B. Sp_who3
C. SQL Server Management Studio (SSMS) Object Explorer
D. SQL Server Data Collector
E. SQL Server Data Tools (SSDT)
F. SQL Server Configuration Manager
Answer: D
Explanation:
Data Collector can gather performance information from multiple SQL Server instances and store it in a single repository. It has three built-in data collecting specifications (data collectors) designed to collect the most important performance metrics. The information collected by default is about disk usage, query statistics, and server activity. The Query Statistics data collection set collects information about query statistics, activity, execution plans and text on the SQL Server instance. Missing indexes can be found with the execution plans.

QUESTION 14
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 sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
A company has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL Database instances. The environment hosts several customer databases.
One customer reports that their database is not responding as quickly as the service level agreements dictate.
You observe that the database is fragmented.
You need to optimize query performance.
Solution: You rebuild all indexes.
Does the solution meet the goal?
A. Yes
B. No
Answer: A
Explanation:
You can remedy index fragmentation by either reorganizing an index or by rebuilding an index.

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 master database.
Does the solution meet the goal?
A. Yes
B. No
Answer: B
Explanation:
Database Mail is guarded by the database role DatabaseMailUserRole in the msdb database, not the master 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.

One customer reports that their database is not responding as quickly as the service level agreements dictate.
You observe that the database is fragmented.
You need to optimize query performance.
Solution: You run the DBCC CHECKDB command.
Does the solution meet the goal?
A. Yes
B. No
Answer: B
Explanation:
DBCC CHECKDB only checks the logical and physical integrity of all the objects in the specified database. It does not update any indexes, and does not improve query performance.
