Duplicate customers exist in a Microsoft Excel workbook. You create a Data Quality Services (DQSJ knowledge base and matching policy to identify these duplicate customers.
You need to identify the duplicate customers.
Which option should you use? (To answer, select the appropriate option in the answer area.)

2. HOTSPOT
You are developing a SQL Server Integration Service (SSIS) package. The package loads a customer dimension table by using a data flow task.
Changes to the customer attributes must be tracked over time.
You need to produce a checksum value to identify the rows that have changed since the last Extract, Transform and Load (ETL) process execution. You need to use the least amount of development effort to achieve this goal.
Which transformation should you use? (To answer, select the appropriate transformation in the answer area.)

3. A SQL Server Integration Services (SSIS) 2012 package currently downloads sales data from a Windows Azure SQL Database database.
To improve sales data accuracy, exchange rates must be downloaded daily from a public HTTP web service instead of from a weekly flat file.
You need to implement the change to the existing package while minimizing the development effort.
What should you use to call the web service to retrieve the daily exchange rates?

A) a Script component
B) a Web Service source
C) a Script task
D) a Web Service task

4. You develop a SQL Server Integration Services (SSIS) package that imports Windows Azure SQL Database data into a data warehouse every night.
The Windows Azure SQL Database data contains many misspellings and variations of abbreviations. To import the data, a developer used the Fuzzy Lookup transformation to choose the closest-matching string from a reference table of allowed values. The number of rows in the reference table is very large.
If no acceptable match is found, the Fuzzy Lookup transformation passes a null value. The current setting for the Fuzzy Lookup similarity threshold is 0.50.
Many values are incorrectly matched.
You need to ensure that more accurate matches are made by the Fuzzy Lookup transformation without degrading performance.
What should you do?

A) Change the Exhaustive property to True.
B) Decrease the maximum number of matches per lookup.
C) Change the similarity threshold to 0.55.
D) Change the similarity threshold to 0.40.

5. Note: This question is part of a series of questions that use the same set of answer choices. An answer choice may be correct for more than one question in the series.

You need to ensure that the reporting database is restored. You also need to ensure that
data loss is minimal.
What should you do?

A) Restore the latest full backup. Then, restore the latest differential backup.
B) Restore the latest full backup. Then, restore each differential backup taken before the time of failure from the most recent full backup.
C) Perform a point-in-time restore.
