QUESTION 1
A SQL Server Integration Services (SSIS) package on a computer is failing periodically in production. The package was
created less than one year ago and was deployed to the SSIS catalog. Sometimes the package is started on a SQL
Agent schedule; sometimes the package is started manually by an SSIS developer by using the Object Explorer in SQL
Server Management Studio. You need to identify the authenticated user responsible for starting the package each time
it failed in the past.
Where can you find this information?
A. the SQL Server Log
B. the SSISDB.[catalog].[executions] view
C. the SSISDB.[catalog].[event_messages] view
D. the SQL Agent Job History
E. the SQL Agent Error Log
Correct Answer: B

QUESTION 4
You are reviewing the design of a student dimension table in an existing data warehouse hosted on SQL Azure.
The current dimension design does not allow the retention of historical changes to student attributes such as
ParentOccupation.
You need to redesign the dimension to enable the full historical reporting of changes to multiple student attributes
including ParentOccupation.
What should you do?
A. Add CurrentValue and PreviousValue columns to the student dimension.
B. Enable Snapshot Isolation on the data warehouse.
C. Add an IsCurrent column to the student dimension.
D. Add StartDate and EndDate columns to the student dimension.
Correct Answer: D
Explanation: Adding a start and end date will give you this ability as when a record is inserted and given a start and end
date, you\\’ll have the ability to determine when they were active therefore giving you a retention of historical changes
QUESTION 5
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains
a unique solution that might meet the stated goals. Some question sets might have more than one correct solution,
while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not
appear in the review screen.
Each night you receive a comma separated values (CSV) file that contains different types of rows. Each row type has a
different structure. Each row in the CSV file is unique. The first column in every row is named Type. This column
identifies
the data type.
For each data type, you need to load data from the CSV file to a target table. A separate table must contain the number
of rows loaded for each data type. Solution: You create a SQL Server Integration Services (SSIS) package as shown in
the exhibit. (Click the Exhibit tab.)
Does the solution meet the goal?
A. Yes
B. No
Correct Answer: A
The conditional split is correctly placed before the count.

warehouse, and SQL Server Analysis Services (SSAS) Tabular and multidimensional models.
The data warehouse stores data related to your company sales, financial transactions and financial budgets All data for
the data warenouse originates from the company\\’s business financial system.
The data warehouse includes the following tables:
The company plans to use Microsoft Azure to store older records from the data warehouse. You must modify the
