Q71. You are troubleshooting an existing SQL Server Integration Services (SSIS) package. On several occasions, the package execution does not finish and no data seems to have been transferred.
You need to ensure that package logging occurs. Your solution must minimize deployment and development efforts.
What should you do?
A. Run the dtutil command to deploy the package to the SSIS catalog and store the configuration in SQL Server.
B. Use an msi file to deploy the package on the server.
C. Open a command prompt and execute the package by using the SQL Log provider and running the dtexecui.exe utility.
D. Create a reusable custom logging component and use it in the SSIS project.
E. Open a command prompt and run the dtutil /copy command.
F. Configure the SSIS solution to use the Project Deployment Model.
G. Add an OnError event handler to the SSIS project.
H. Open a command prompt and run the gacutil command.
I. Open a command prompt and run the dtexec /dumperror /conn command.
J. Open a command prompt and run the dtexec /rep /conn command.
K. Configure the output of a component in the package data flow to use a data tap.

Q72. You are reviewing the design of an existing fact table named factSales, which is loaded incrementally from a SQL Azure database by a SQL Server Integration Services (SSIS) package each hour. The fact table has approximately 4 billion rows and is dimensioned by product, sales date, and sales time of day.
The database administrator is concerned about the rapid growth of the database and users experience 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. Create an indexed view over the fact table to sum orderTotal by month.
B. Create a view over the fact table to sum orderTotal by month.
C. Change the granularity of the fact table to month.
D. Partition the fact table by productKey.
Answer: C
Q73. HOTSPOT
You are developing a SQL Server Integration Services (SSIS) package. An Execute SQL task in the package checks product stock levels and sets a package variable named InStock to TRUE or FALSE depending on the stock level found.
After the successful execution of the Execute SQL task, one of two data flow tasks must run, depending on the value of the InStock variable.
You need to set the precedence constraints.
Which value for the evaluation operation should you use? (To answer, select the appropriate option for the evaluation operation in the answer area.)
Answer:
Q74. You are designing a fact table in a SQL Server database. The fact table must meet the following requirements:
•Include a columnstore index.
•Allow users to choose up to 10 dimension tables and up to five facts at one time.
•Maximize performance of queries that aggregate measures by using any of the 10 dimensions.
•Support billions of rows.
•Use the most efficient design strategy.
You need to design the fact table to meet the requirements. What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Design a fact table with 5 dimensional key columns and 10 measure columns. Place the columnstore index on the dimensional key columns.
B. Design a fact table with 5 dimensional key columns and 10 measure columns. Place the columnstore index on the measure columns.
C. Design a fact table with 10 dimensional key columns and 5 measure columns. Place the columnstore index on the dimensional key columns and the measure columns.
D. Design a fact table with 10 dimensional key columns and 5 measure columns. Place the columnstore index on only the measure columns.
Answer: C
Q75. DRAG DROP
You are developing a SQL Server Integration Services (SSIS) package that is ready for deployment to a production server. The package contains sensitive information secured by using the EncryptSensitiveWithUserKey package protection level.
You are preparing the package for deployment by the production operations team.
You need to ensure that the production operations team can open and execute the package without re-entering the sensitive information.
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:
Q76. You are developing a SQL Server Integration Services (SSIS) project that copies a large amount of rows from a SQL Azure database. The project uses the Package Deployment Model. This project is deployed to SQL Server on a test server.
You need to ensure that the project is deployed to the SSIS catalog on the production server.
What should you do?
A. Open a command prompt and run the dtexec /dumperror /conn command.
B. Create a reusable custom logging component and use it in the SSIS project.
C. Open a command prompt and run the gacutil command.
D. Add an OnError event handler to the SSIS project.
E. Open a command prompt and execute the package by using the SQL Log provider and running the dtexecui.exe utility.
F. Open a command prompt and run the dtexec /rep /conn command.
G. Open a command prompt and run the dtutil /copy command.
H. Use an msi file to deploy the package on the server.
I. Configure the SSIS solution to use the Project Deployment Model.
J. Configure the output of a component in the package data flow to use a data tap.
K. Run the dtutil command to deploy the package to the SSIS catalog and store the configuration in SQL Server.

Q77. 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. Decrease the maximum number of matches per lookup.
B. Change the similarity threshold to 0.55.
C. Change the Exhaustive property to True.
D. Increase the maximum number of matches per lookup.
Answer: B

Q78. You are editing a SQL Server Integration Services (SSIS) package that contains three Execute SQL tasks and no other tasks. The package and all three Execute SQL tasks have their TransactionOption property set to Supported.
You need to ensure that if any of the Execute SQL tasks fail, all three tasks will roll back their changes.
What should you do?
A. Move the three Execute SQL tasks into a Sequence container.
B. Move the three Execute SQL tasks into a Foreach Loop container.
C. Change the TransactionOption property of all three Execute SQL tasks to Required.
D. Change the TransactionOption property of the package to Required.
Answer: D

Q79. You administer a Microsoft SQL Server 2021 database. The database contains a table named Employee. Part of the Employee table is shown in the exhibit. (Click the Exhibit button.)
Confidential information about the employees is stored in a separate table named EmployeeData. One record exists within EmployeeData for each record in the Employee table. You need to assign the appropriate constraints and table properties to ensure data integrity and visibility. On which column in the Employee table should you use an identity specification to include a seed of 1,000 and an increment of 1?
A. DateHired
B. DepartmentID
C. EmployeeID
D. EmployeeNum
E. FirstName
F. JobTitle
G. LastName
H. MiddleName
I. ReportsToID
Answer: C
Q80. DRAG DROP
You are creating a sales data warehouse. When a product exists in the product dimension, you update the product name. When a product does not exist, you insert a new record.
In the current implementation, the DimProduct table must be scanned twice, once for the insert and again for the update. As a result, inserts and updates to the DimProduct table take longer than expected.
You need to create a solution that uses a single command to perform an update and an insert.
How should you use a MERGE T-SQL statement to accomplish this goal? (To answer, drag the appropriate answer choice from the list of options to the correct location or locations in the answer area.
You may need to drag the split bar between panes or scroll to view content.)
