You are a database developer for an application hosted on a Microsoft SQL Server 2014 server. The database contains two tables that have the following definitions:

Global customers place orders from several countries. You need to view the country from which each customer has placed the most orders.
Which Transact-SQL query do you use?

• A.SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer cINNER JOIN(SELECT CustomerID, ShippingCountry,COUNT(OrderAmount) DESC) AS OrderAmountFROM OrdersGROUP BY CustomerID, ShippingCountry) AS oON c.CustomerID = o.CustomerIDORDER BY OrderAmount DESC
• B.SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer cINNER JOIN(SELECT CustomerID, ShippingCountry,RANK() OVER (PARTITION BY CustomerIDORDER BY COUNT(OrderAmount) DESC) AS RnkFROM OrdersGROUP BY CustomerID, ShippingCountry) AS oON c.CustomerID = o.CustomerIDWHERE o.Rnk = 1
• C.SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer cINNER JOIN(SELECT CustomerID, ShippingCountry,RANK() OVER (PARTITION BY CustomerIDORDER BY OrderAmount DESC) AS RnkFROM OrdersGROUP BY CustomerID, ShippingCountry) AS oON c.CustomerID = o.CustomerIDWHERE o.Rnk = 1
• D.SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM(SELECT c.CustomerID, c.CustomerName, o.ShippingCountry, RANK()OVER (PARTITION BY CustomerIDORDER BY COUNT(o.OrderAmount) ASC) AS RnkFROM Customer cINNER JOIN Orders oON c.CustomerID = o.CustomerIDGROUP BY c.CustomerID, c.CustomerName, o.ShippingCountry) cs WHERE Rnk = 1

You use Resource Manager to deploy a new Microsoft SQL Server instance in a Microsoft Azure virtual machine (VM) that uses Premium storage. The combined initial size of the SQL Server user database files is expected to be over 200 gigabytes (GB). You must maximize performance for the database files and the log file.
You add the following additional drive volumes to the VM:

You have the following requirements:
You need to deploy the SQL instance.
In the table below, identify the drive where you must store each SQL Server file type.
NOTE: Make only one selection in each column. Each correct selection is worth one point.

正解：

Explanation:
Enable read caching on the disk(s) hosting the data files and TempDB.
Do not enable caching on disk(s) hosting the log file. Host caching is not used for log files.

You have database that contains a 400-GB table that is read-only.
You need to enable the Stretch Database feature.
How should you complete the statement? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Select and Place:

Explanation:
Section: Deploy and migrate applications
To configure an existing table for Stretch Database, run the ALTER TABLE command.
Here's an example that migrates the entire table and begins data migration immediately.
USE <Stretch-enabled database name>;
GO
ALTER TABLE <table name>
SET ( REMOTE_DATA_ARCHIVE = ON ( MIGRATION_STATE = OUTBOUND ) ) ;
GO

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?

• A.Record the LSN of the transaction log at 08:59 hours. Perform a transaction log backup at17:01 hours.
• B.Create a marked transaction in the transaction log at 08:59 hours. Perform a transaction log backup at 17:01 hours.
• C.Create a marked transaction in the transaction log at 08:59 hours. Perform a transaction log backup at 08:59 hours.
• D.Perform a differential backup at 08:59 hours.
• E.Create a database snapshot at 08:59 hours.
• F.Record the LSN of the transaction log at 08:59 hours. Perform a transaction log backup at08:59 hours.

You plan to migrate a Microsoft sql server instance between physical servers.
You must migrate the metadata associated with the database instance.
You need to ensure that the new instance retains the existing jobs and alerts.
Solutions: You restore the model database.
Does the solution meet the goal?

• A.Yes
• B.No
