Question 8
You have a database named OnlineSales that contains a table named Customers. You plan to copy incremental changes from the Customers table to a data warehouse every hour.
You need to enable change tracking for the Customers table.
How should you complete the Transact-SQL statements? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segment 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.
Solution:
Box 1: DATABASE [OnlineSales]
Before you can use change tracking, you must enable change tracking at the database level. The following example shows how to enable change tracking by using ALTER DATABASE.
ALTER DATABASE AdventureWorks2012 SET CHANGE_TRACKING = ON
(CHANGE_RETENTION = 2 DAYS, AUTO_CLEANUP = ON) Box 2: CHANGE_TRACKING = ON
ALTER SET CHANGE_RETENTION
Box 3: ALTER TABLE [dbo].[Customers]
Change tracking must be enabled for each table that you want tracked. When change tracking is enabled, change tracking information is maintained for all rows in the table that are affected by a DML operation.
The following example shows how to enable change tracking for a table by using ALTER TABLE. ALTER TABLE Person.Contact
ENABLE CHANGE_TRACKING
WITH (TRACK_COLUMNS_UPDATED = ON) Box 4: ENABLE CHANGE_TRACKING

What should you do?
Question 11
You are developing a Microsoft SQL Server Integration Services (SSIS) package to incrementally load new and changed records from a data source.
The SSIS package must load new records into Table1 and updated records into Table1_Updates. After loading records, the package must call a Transact-SQL statement to process updated rows according to existing business logic.
You need to complete the design of the SSIS package.
Which tasks should you use? To answer, drag the appropriate SSIS objects to the correct targets. Each SSIS object 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.
Solution:
Step 1: CDC Control Task Get Processing Range Step 2: Mark Processed Range
Step 3: Data Flow
The Data Flow task encapsulates the data flow engine that moves data between sources and destinations, and lets the user transform, clean, and modify data as it is moved. Addition of a Data Flow task to a package control flow makes it possible for the package to extract, transform, and load data.
Step 4: CDC Source
The CDC source reads a range of change data from SQL Server 2017 change tables and delivers the changes downstream to other SSIS component.
Step 5: CDC Splitter
The CDC splitter splits a single flow of change rows from a CDC source data flow into different data flows for Insert, Update and Delete operations.

Question 22
You need to recommend a storage solution for a data warehouse that minimizes load times. The solution must provide availability if a hard disk fails.
Which RAID configuration should you recommend for each type of database file? To answer, drag the appropriate RAID configurations to the correct database file types. Each RAID configuration 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.
Solution:
Box 1: RAID 5
RAID 5 is the similar to that of RAID 0 provided that the number of disks is the same. However, due to the fact that it is useless to read the parity data, the read speed is just (N-1) times faster but not N times as in RAID 0.
Box 2: RAID 10
Always place log files on RAID 1+0 (or RAID 1) disks. This provides better protection from hardware failure, and better write performance.
Note: In general RAID 1+0 will provide better throughput for write-intensive applications. The amount of performance gained will vary based on the HW vendor’s RAID implementations. Most common alternative to RAID 1+0 is RAID 5. Generally, RAID 1+0 provides better write performance than any other RAID level providing data protection, including RAID 5.

RAID 5 is the similar to that of RAID 0 provided that the number of disks is the same. However, due to the fact that it is useless to read the parity data, the read speed is just (N-1) times faster but not N times as in RAID 0.
Box 2: RAID 10
Always place log files on RAID 1+0 (or RAID 1) disks. This provides better protection from hardware failure, and better write performance.
Note: In general RAID 1+0 will provide better throughput for write-intensive applications. The amount of performance gained will vary based on the HW vendor’s RAID implementations. Most common alternative to RAID 1+0 is RAID 5. Generally, RAID 1+0 provides better write performance than any other RAID level providing data protection, including RAID 5.

Question 23
You have a server that has Data Quality Services (DQS) installed.
You create a matching policy that contains one matching rule.
You need to configure the Similarity of Similar percentage that defines a match. Which similarity percentage will always generate a similarity score of 0?

Question 24
You have a Microsoft SQL Server Integration Services (SSIS) package that loads data into a data warehouse each night from a transactional system. The package also loads data from a set of Comma-Separated Values (CSV) files that are provided by your company’s finance department.
The SSIS package processes each CSV file in a folder. The package reads the file name for the current file into a variable and uses that value to write a log entry to a database table.
You need to debug the package and determine the value of the variable before each file is processed.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Solution:
You debug control flows.
The Foreach Loop container is used for looping through a group of files. Put the breakpoint on it.
The Locals window displays information about the local expressions in the current scope of the Transact-SQL debugger.
