QUESTION 17
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 five servers that run Microsoft Windows 2012 R2. Each server hosts a Microsoft SQL Server instance. The topology for the environment is shown in the
following diagram.
You have an Always On Availability group named AG1. The details for AG1 are shown in the following table.
Instance1 experiences heavy read-write traffic. The instance hosts a database named OperationsMain that is four terabytes (TB) in size. The database has
multiple data files and filegroups. One of the filegroups is read_only and is half of the total database size.
Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O.
Instance5 hosts a database named StagedExternal. A nightly BULK INSERT process loads data into an empty table that has a rowstore clustered index and two
nonclustered rowstore indexes.
You must minimize the growth of the StagedExternal database log file during the BULK INSERT operations and perform point-in-time recovery after the BULK
INSERT transaction. Changes made must not interrupt the log backup chain.
You plan to add a new instance named Instance6 to a datacenter that is geographically distant from Site1 and Site2. You must minimize latency between the
nodes in AG1.
All databases use the full recovery model. All backups are written to the network location \\SQLBackup\. A separate process copies backups to an offsite location.
You should minimize both the time required to restore the databases and the space required to store backups. The recovery point objective (RPO) for each
instance is shown in the following table.

LX0-102 dumps

Full backups of OperationsMain take longer than six hours to complete. All SQL Server backups use the keyword COMPRESSION.
You plan to deploy the following solutions to the environment. The solutions will access a database named DB1 that is part of AG1.
The wait statistics monitoring requirements for the instances are described in the following table.
You need to create a backup plan for Instance4.
Which backup plan should you create?
A. Weekly full backups, nightly differential. No transaction log backups are necessary.
B. Weekly full backups, nightly differential backups, transaction log backups every 5 minutes.
C. Weekly full backups, nightly differential backups, transaction log backups every 12 hours.
D. Weekly full backups, nightly differential backups, nightly transaction log backups.
Correct Answer: B
Explanation
Explanation/Reference:
From scenario: Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O. The recovery point objective of Instancse4 is 60
minutes. RecoveryPoint Objectives are commonly described as the amount of data that was lost during the outage and recovery period.

QUESTION 18
You manage a SQL Server 2016 instance that contains a database named DB1. Users report that some queries to DB1 take longer than expected. Although most
queries run in less than one second, some queries take up to 20 seconds to run.
You need to view all of the performance statistics for each database file.
Which method should you use?
A. Query the sys.dm_os_tasks dynamic management view.
B. Query the sys.dm_os_performance_counters dynamic management view.
C. Query the sys.dm_io_virtual_file_stats dynamic management function.
D. Examine the Data File I/O pane in Activity Monitor.
Correct Answer: C
Explanation
Explanation/Reference:
sys.dm_io_virtual_file_stats
Returns I/O statistics for data and log files.
Reference: sys.dm_io_virtual_file_stats (Transact-SQL)
