Actual exam question from Microsoft's 70-463

Question #: 22
Topic #: 1

You are developing a data flow transformation to merge two data sources. One source contains product data and the other source contains data about the country in which the product was manufactured. Both data sources contain a two-character CountryCode column and both use SQL Server. Both data sources contain an
ORDER BY clause to sort the data by the CountryCode column in ascending order.
You use a Merge Join transformation to join the data.

You need to ensure that the Merge Join transformation works correctly without additional transformations.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

A. Change the ORDER BY clause on the product source to order by ProductName.
B. Change the Merge Join transformation to a Merge transformation.
C. Set the appropriate SortKeyPosition properties on the data sources.
D. Set the IsSorted property on both data sources.
E. Set the ValidateExternalMetaData property on the Merge Join transformation to True.
F. Set the MaxBuffersPerlnput property on the Merge Join transformation to 2.
