slightly different in each data mart.
You need to design a consolidated dimensional structure that will be easy to maintain while ensuring that
all dimensional data from the three original solutions is represented.
What should you do?
A.Create a junk dimension for the geography dimension.
B.Implement change data capture.
C.Create a conformed dimension for the geography dimension.
D.Create three geography dimensions.

NO.2 DRAG DROP
A new SQL Server Integration Services (SSIS) project is deployed to the SSIS catalog.
To troubleshoot some data issues, you must output the data streaming through several data flows into text
files for further analysis.You have the list of data flow package paths and identification strings of the
various task components that must be analyzed.
You need to create these output files with the least amount of administrative and development effort.
Which three stored procedures should you execute in sequence? (To answer, move the appropriate
actions from the list of actions to the answer area and arrange them in the correct order.)
Answer:

NO.3 You are designing a data warehouse with two fact tables.The first table contains sales per month and
the second table contains orders per day.
Referential integrity must be enforced declaratively.
You need to design a solution that can join a single time dimension to both fact tables.
What should you do?
A.Create a time mapping table.
B.Change the level of granularity in both fact tables to be the same.
C.Merge the fact tables.
D.Create a view on the sales table.
Answer: C

NO.4 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
Answer: B

NO.5 You are designing a data warehouse for a software distribution business that stores sales by software
title.It stores sales targets by software category.Software titles are classified into subcategories and
categories.Each software title is included in only a single software subcategory, and each subcategory is
included in only a single category.The data warehouse will be a data source for an Analysis Services
cube.
The data warehouse contains two fact tables:
factSales, used to record daily sales by software title
factTarget, used to record the monthly sales targets by software category
Reports must be developed against the warehouse that reports sales by software title, category and
subcategory, and sales targets.
You need to design the software title dimension.The solution should use as few tables as possible while
supporting all the requirements.
What should you do?
A.Create three software tables, dimSoftware, dimSoftwareCategory.and dimSoftwareSubcategory and a
fourth bridge table that joins software titles to their appropriate category and subcategory table records
with foreign key constraints.Direct the cube developer to use key granularity attributes.
B.Create three software tables, dimSoftware, dimSoftwareCategory, and
dimSoftwareSubcategory.Connect factSales to all three tables and connect factTarget to
dimSoftwareCategory with foreign key constraints.Direct the cube developer to use key granularity
attributes.
C.Create one table, dimSoftware, which contains Software Detail, Category, and Subcategory
columns.Connect factSales to dimSoftware with a foreign key constraint.Direct the cube developer to use
a non-key granularity attribute for factTarget.
D.Create two tables, dimSoftware and dimSoftwareCategory.Connect factSales to dimSoftware and
factTarget to dimSoftwareCategory with foreign key constraints.Direct the cube developer to use key
granularity attributes.

NO.6 DRAG DROP
You are editing a SQL Server Integration Services (SSIS) package that contains a task with a sensitive
property.
You need to create a project parameter and configure it so that its value is encrypted when it is deployed
to the SSIS catalog.
Which three steps 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.)
Answer:

NO.7 You are reviewing the design of an existing fact table named factSales, which is loaded from a SQL
Azure database by a SQL Server Integration Services (SSIS) package each day.The fact table has
approximately 1 billion rows and is dimensioned by product, sales date, and sales time of day.
The database administrator is concerned about the growth of the database.Users report poor reporting
performance against this database.Reporting requirements have recently changed and the only
remaining report that uses this fact table reports sales by product name, sale month, and sale year.No
other reports will be created against this table.
You need to reduce the report processing time and minimize the growth of the database.
What should you do?
A.Partition the table by product type.
B.Create a view over the fact table to aggregate sales by month.
C.Change the granularity of the fact table to month.
D.Create an indexed view over the fact table to aggregate sales by month.
Answer: C

You need to ensure that the username and password values are encrypted when they are deployed.
What should you do?
