Q5. 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.
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 reduce the amount of time it takes to backup OperationsMain. What should you do?
A. Modify the backup script to use the keyword SKIP in the FILE_SNAPSHOT statement.
B. Modify the backup script to use the keyword SKIP in the WITH statement
C. Modify the backup script to use the keyword NO_COMPRESSION in the WITH statement.
D. Modify the full database backups script to stripe the backup across multiple backup files.
Answer: D
Explanation:
One of the filegroup is read_only should be as it only need to be backup up once. Partial backups are useful whenever you want to exclude read-only filegroups. A partial backup resembles a full database backup, but a partial backup does not contain all the filegroups. Instead, for a read-write database, a partial backup contains the data in the primary filegroup, every read-write filegroup, and, optionally, one or more read-only files. A partial backup of a read-only database contains only the primary filegroup.
From scenario: Instance1 experiences heavy read-write traffic. The instance hosts a database named OperationsMainthat 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.

Q6. 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.

You need to be able to send the entire product catalog to all branch offices on a monthly basis. Which configuration should you use?
A. • Two servers configured in the same data center
• A primary server configured to perform log-shipping every 10 minutes
• A backup server configured as a warm standby
B. • SQL Server that includes an application database configured to perform transactional replication
C. • Two servers configured in the same data center
• SQL Server Availability Group configured in Asynchronous-Commit Availability Mode
• One server configured as an Active Secondary
D. • Two servers configured in a Windows Failover Cluster in the same data center
• SQL Server configured as a clustered instance
E. • SQL Server that includes an application database configured to perform snapshot replication
F. • Two servers configured in different data centers
• SQL Server Availability Group configured in Synchronous-Commit Availability Mode
• One server configured as an Active Secondary
G. • Two servers configured on the same subnet
• SQL Server Availability Group configured in Synchronous-Commit Availability Mode
H. • Two servers configured in different data centers
• SQL Server Availability Group configured in Asynchronous-Commit Availability Mode
Answer: E
Explanation:
I think that i'll stick with "E" as that was the original answer and "You need to be able to send the entire product catalog to all branch offices on a monthly basis. " definatly sounds like it wants snapshot
Q8. You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN).
The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D). A transaction log of 10 GB is located on a dedicated LUN (drive E). Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands.
Each data load adds 3 GB of data to the database.
These data load operations must occur in the minimum amount of time. A full database backup is performed every Sunday at 10:00 hours.
Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours. You need to ensure that the minimum amount of data is lost.
Which recovery model should the database use?
A. FULL
B. DBO_ONLY
C. CONTINUE_AFTER_ERROR
D. CHECKSUM
E. NO_CHECKSUM
F. SIMPLE
G. Transaction log
H. SKIP
I. RESTART
J. COPY_ONLY
K. NORECOVERY
L. BULK_LOGGED
M. Differential
N. STANDBY
Answer: L
