Question No : 1
You administer a Microsoft SQL Server 2014 instance.
The instance contains a database that supports a retail sales application. The application generates hundreds of transactions per second and is online 24 hours per day and 7 days per week.
You plan to define a backup strategy for the database. You need to ensure that the following requirements are met:
No more than 5 minutes worth of transactions are lost. Data can be recovered by using the minimum amount of administrative effort.
What should you do? Choose all that apply.
정답: Explanation:
The full recovery model uses log backups to prevent data loss in the broadest range of failure scenarios, and backing and restoring the transaction log (log backups) is required. The advantage of using log backups is that they let you restore a database to any point of time that is contained within a log backup (point-in-time recovery). You can use a series of log backups to roll a database forward to any point in time that is contained in one of the log backups. Be aware that to minimize your restore time, you can supplement each full backup with a series of differential backups of the same data.

Question No : 2
You administer a Microsoft SQL Server 2014 instance named SQL2012 that hosts an OLTP database of 1 terabyte in size.
The database is modified by users only from Monday through Friday from 09:00 hours to 17:00 hours. Users modify more than 30 percent of the data in the database during the week.
Backups are performed as shown in the following schedule:
The Finance department plans to execute a batch process every Saturday at 09:00 hours. This batch process will take a maximum of 8 hours to complete.
The batch process will update three tables that are 10 GB in size. The batch process will update these tables multiple times.
When the batch process completes, the Finance department runs a report to find out whether the batch process has completed correctly.
You need to ensure that if the Finance department disapproves the batch process, the batch operation can be rolled back in the minimum amount of time.
What should you do on Saturday?
You administer a Microsoft SQL Server 2014 instance that contains a financial database hosted on a storage area network (SAN).
The financial database has the following characteristics:
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 backup size is as small as possible.
Which backup should you perform every two hours?
정답: Explanation:
Minimally, you must have created at least one full backup before you can create any log backups. After that, the transaction log can be backed up at any time unless the log is already being backed up.

On Wednesday at 10:00 hours, the development team requests you to refresh the database on a development server by using the most recent version.
You need to perform a full database backup that will be restored on the development server.
Which backup option should you use?
정답: Explanation:
COPY_ONLY specifies that the backup is a copy-only backup, which does not affect the normal sequence of backups. A copy-only backup is created independently of your regularly scheduled, conventional backups. A copy-only backup does not affect your overall backup and restore procedures for the database.

You need to ensure that your backup will continue if any invalid checksum is encountered.
Which backup option should you use?
정답: Explanation:
The CONTINUE_AFTER_ERROR option, of the Transact-SQL BACKUP command, instructs BACKUP to continue despite encountering errors such as invalid checksums or torn pages.

Question No : 7
You administer a Microsoft SQL Server 2014 Enterprise Edition server that uses 64 cores.
You discover performance issues when large amounts of data are written to tables under heavy system load.
You need to limit the number of cores that handle I/O.
What should you configure?
정답: Explanation:
The affinity Input-Output (I/O) mask Server Configuration Option.
To carry out multitasking, Microsoft Windows 2000 and Windows Server 2003 sometimes move process threads among different processors. Although efficient from an operating system point of view, this activity can reduce Microsoft SQL Server performance under heavy system loads, as each processor cache is repeatedly reloaded with data. Assigning processors to specific threads can improve performance under these conditions by eliminating processor reloads; such an association between a thread and a processor is called processor affinity.

You administer a Microsoft SQL Server 2014 instance. After a routine shutdown, the drive that contains tempdb fails.
You need to be able to start the SQL Server.
What should you do?
정답: Explanation:
If you have configuration problems that prevent the server from starting, you can start an instance of Microsoft SQL Server by using the minimal configuration startup option.
When you start an instance of SQL Server in minimal configuration mode, note the following:
Only a single user can connect, and the CHECKPOINT process is not executed.
Remote access and read-ahead are disabled.
Startup stored procedures do not run.
tempdb is configured at the smallest possible size.

You administer a Microsoft SQL Server 2014 failover cluster that contains two nodes named Node A and Node B. A single instance of SQL Server is installed on the cluster.
An additional node named Node C has been added to the existing cluster.
You need to ensure that the SQL Server instance can use all nodes of the cluster.
What should you do?
정답: 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. Then, select Add node to a SQL Server failover cluster.

Question No : 13
You administer a Microsoft SQL Server 2014 database.
You need to ensure that the size of the transaction log file does not exceed 2 GB.
What should you do?
정답: 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.

HOTSPOT
You need to set up the service accounts that the database engine and SQL Server Agent services will use.
How should you design the solution? To answer, select the appropriate configuration options in the answer area.
정답:
Explanation:
Box 1: Domain Account
The service startup account defines the Microsoft Windows account in which SQL Server Agent runs and its network permissions. SQL Server Agent runs as a specified user account.
You select an account for the SQL Server Agent service by using SQL Server Configuration Manager, where you can choose fromthe following options:
* Built-in account. You can choose from a list of the following built-in Windows service accounts: Local System account.
* This account. Lets you specify the Windows domain account in which the SQL Server Agent service runs.
Box2: Domain users
Microsoft recommends choosing a Windows user account that is not a member of the Windows Administrators group.
Box 3: Managed Service Accounts
When resources external to the SQL Server computer are needed, Microsoft recommends using a Managed Service Account (MSA), configured with the minimum privileges necessary.
Note: A Managed Service Account (MSA) can run services on a computer in a secure and easy to maintain manner, while maintaining the capability to connect to network resources as a specific user principal.
