Q

The answer is

You are developing a project that contains multiple SQL Server Integration Services (SSIS) packages. The packages will be deployed to the SSIS catalog. One of the steps in each package accesses an FTP
site to download sales transaction data. You create project parameters to store the username and password that are used to access the FTP site. You need to ensure that the username and password values are encrypted when they are deployed. What should you do?
A. Set the Sensitive property of the parameters to True.
B. Set the Protection Level property of the package to Encrypt Sensitive With User Key.
C. Change the parameters to package parameters.
D. Change the project to the Legacy Deployment model.

Q

The answer is

You develop a SQL Server Integration Services (SSIS) package that imports SQL Azure data into a data warehouse every night. The SQL Azure 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. Change the similarity threshold to 0.55.
C. Change the similarity threshold to 0.40.
D. Increase the maximum number of matches per lookup

A

A. Change the Exhaustive property to True.
B. Change the similarity threshold to 0.55.
C. Change the similarity threshold to 0.40.

Q

The answer is

A SQL Server Integration Services (SSIS) package named DataFeed interacts with an external vendor data feed. The package is executed several times a day, either as part of other packages’ control flow or by itself. The external data feed is unreliable because network failures and slow response times are
frequent. The package is currently deployed on the file system. To analyze the reliability of the external data feed, you must collect execution data.
Every time the DataFeed package is executed, the following information must be logged:
- Start Time
- End Time
- Execution Result
- Execution Duration
You need to design a logging solution that meets the requirements by using the least amount of administrative and development effort.
Which three 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.)

Add OnError and OnWarning event handlers.
Query the catalog.executable_statistics view.
Query the ExecutionLog table.
Deploy the project that contains the package to the SSIS catalog and execute the package on the server.
Deploy the package to the msdb database,
Add an Execute SQL task to the event handlers.
Query the catalog.execution_data_statistics view.
Create a new project and add the package to the project.

A

Create a new project and add the package to the project.
Deploy the project that contains the package to the SSIS catalog and execute the package on the server.
Query the catalog.execution_data_statistics view.

Q

The answer is

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

Q

The answer is

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 admin 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.

Q

The answer is

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 4th 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.

Q

The answer is

You are designing a data warehouse hosted on SQL Azure. The data warehouse currently includes the dimUser and dimDistrict dimension tables and the factSales fact table. The dimUser table contains records for each user permitted to run reports against the warehouse; and the dimDistrict table contains information about sales districts.

Q

The answer is

You are implementing the indexing strategy for a fact table in a data warehouse. The fact table is named Quotes. The table has no indexes and consists of seven columns: [ID], [QuoteDate], [Open], [Close], [High], [Low], [Volume]
Each of the following queries must be able to use a columnstore index:
select AVG([Close]) as [average close] from Quotes where QuoteDate between ‘20100101’ AND ‘20101231’

select AVG([High]-[Low]) as [AverageRange] from Quotes where QuoteDate between ‘20100101’ AND ‘20101231’

select sum([volume]) as [SumVolume] from Quotes where QuoteDate between ‘20100101’ AND ‘20101231’

You need to ensure that the indexing strategy meets the requirements. The strategy must also minimize the number and size of the indexes. What should you do?

A. Create one columnstore index that contains [ID], [Close], [High], [Low], [Volume] and [QuoteDate].
B. Create three coiumnstore indexes:
- One containing [QuoteDate] and [Close]
- One containing [QuoteDate], [High], and [Low]
- One containing [QuoteDate] and [Volume]
C. Create one columnstore index that contains [TradeDate], [Close], [High], [Low], and [Volume].
