2021 Feb exam prep 70-467:
Q21. You are designing an extract, transform, load (ETL) process for loading data from a SQL Azure database into a large fact table in a data warehouse each day with the prior day's sales data.
The ETL process for the fact table must meet the following requirements:
Load new data in the shortest possible time.
Remove data that is more than 36 months old.
Minimize record locking.
Minimize impact on the transaction log.
You need to design an ETL process that meets the requirements.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Partition the fact table by date. Insert new data directly into the fact table and delete old data directly from the fact table.
B. Partition the fact table by customer. Use partition switching both to remove old data and to load new data into each partition.
C. Partition the fact table by date. Use partition switching and staging tables both to remove old data and to load new data.
D. Partition the fact table by date. Use partition switching and a staging table to remove old data. Insert new data directly into the fact table.
Answer: C
Q22. 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
Q23. You are designing a SQL Server Integration Services (SSIS) solution. The solution will contain an SSIS project that includes several SSIS packages. Each SSIS package will
define the same connection managers and variables.
You have the following requirements:
. Ensure that the deployment model supports changing the content of connection strings by using parameters at execution time. . Ensure that the deployment model automatically starts from calls to the
catalog.start_execution stored procedure in the SSISDB database.
. Maximize performance at execution time.
. Minimize development effort.
You need to design a solution that meets the requirements.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Use a project deployment model. Modify connection manager properties to use project parameters. Ensure that the SSISDB database is created.
B. Use a project deployment model. Configure connections in an XML configuration file referenced by an environment variable that corresponds to the SQL Server environment of each SSIS package.
C. Use a package deployment model. Use a SQL Server package configuration with a common filter. Change the contents of the SSIS Configurations table at runtime.
D. Use a package deployment model. Save each SSIS package to a file share that can be accessed from all environments.
Answer: A
Q24. You need to design the dimCustomers table.
Which design approach should you use?
A. Reference dimension
B. Type 2 slowly changing dimension
C. Junk dimension
D. Conformed dimension
E. Type 1 slowly changing dimension
Answer: B
Q25. You need to ensure that the Sales measure in the Power View field list meets the requirements.
What should you do? (Each correct answer presents a part of the solution. Choose all that apply.)
A. Format the column to display zero decimal places.
B. Hide the column from client tools.
C. Create a measure named Sales based on the column by using the Data Analysis Expressions (DAX) SUM() function.
D. Rename the column to Sales.
E. Format the measure to display zero decimal places.
Answer: AC

Q26. You need to select the appropriate mode for the Sales database.
Which mode should you select?
A. ROLAP
B. Direct Query
C. MOLAP
D. In-Memory
Answer: B
Q27. You are redesigning a SQL Server Analysis Services (SSAS) database that contains a cube named Sales. Before the initial deployment of the cube, partition design was optimized for processing time. The cube currently includes five partitions named FactSalesl through FactSales5. Each partition contains from 1 million to 2 million rows.
A. Use the Usage-Based Optimization Wizard to create aggregations for the current partitions.
B. Use the Aggregation Design Wizard to create aggregations for the current partitions.
C. Combine all the partitions into a single partition. Use the Usage-Based Optimization Wizard to create aggregations.
D. Combine all the partitions into a single partition. Use the Aggregation Design Wizard to create aggregations.
Answer: C
Q28. You need to fix the PowerPivot data refresh problem by using the least amount of administrative effort.
What should you do?
A. Use the PowerPivot Configuration Tool and select the Upgrade Features, Services,
Applications and Solutions option.
B. Use the PowerPivot Configuration Tool and select the Configure or Repair PowerPivot
for SharePoint option.
C Reinstall SSAS in PowerPivot for SharePoint mode by using the SQL Server 2012
installation media.
C. In SharePoint Central Administration, create a target application and configure the
PowerPivot service application settings to use the target application.
Answer: B
Q29. A group of report writers develop reports. The report writers currently use Report Builder
1.0 and report models. The report writers are not trained on SQL Server query writing. Their report assignments come from various departments within the organization.
The company is upgrading to SQL Server 2012 with SQL Server Reporting Services (SSRS) in native mode. After the upgrade, reports will retrieve data from a large new data warehouse that will reside on an instance of the SQL Server 2012 Database Engine. Reports for each department will retrieve data from only a subset of the data warehouse tables.
You are designing the data access strategy. You have the following requirements:
. Ensure that report writers can create only reports that display data which they have database permissions to view. . Minimize the effort required to update connection strings for all reports developed by the report writers. . Minimize the number of fields visible in a specific report for report writers who work for multiple departments.
You need to design the data access strategy.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
