Topic 6, WingTip Toys General Background
You are a data architect for WingTip Toys. The company uses SQL Server 2012 Enterprise edition. SQL Server Analysis Services (SSAS) and SQL Server Reporting Services (SSRS) are installed on separate servers.
The company#39;s data warehouse initially contained less than 100 MB and 100 million rows of data from only one data source. It now contains more than 10 TB and 10 billion rows of data, in 25 tables, from 12 data sources.
The largest table in the data warehouse, the factOrders table, contains 5 TB of data. The factOrders table contains three date keys: OrderDateKey InvoiceDateKey, and ShipDateKey. The data warehouse server has 1 TB of RAM. Memory usage is currently at 20 percent.
One billion rows of data are added to the data warehouse each month. New data is copied each night from the data sources into SQL Server staging tables, and existing records are not updated. The largest data set is order information, which is loaded in parallel into multiple staging tables, one for each data source. All the staging tables have the same structure and belong to the same filegroup as the factOrders table.
The dimCustomers table stores customer information that may change over time.
You are developing three SSAS databases, as described in the following table.
Business users frequently generate reports in Microsoft Excel by using PowerPivot. The PowerPivot Management Dashboard does not currently display any usage data.
Several SSRS reports exist that use the data warehouse as a source. The data warehouse queries are aggregate queries that use the factOrders table and one or more dimension tables. All SSRS data sources use Integrated Windows authentication.
SSRS displays a security access error message when managers run SSRS reports based on the Operations database.
Reporting performance has become unacceptably slow.
Improve the query speed of the SSRS reports.
Allow business users to create reports by using PowerPivot and Power View.
Ensure that all users other than business users can view metadata for the Customers dimension. Ensure that business users cannot view metadata for the Customers dimension.
Modify the tables in the data warehouse to minimize aggregate query processing time. Minimize disk storage in the data warehouse.
Ensure that all multidimensional models process data as quickly as possible.
Create a fact table named factCustomerContact in the data warehouse to store the contact date, customer key, and communication type for each instance of customer contact.
Store the history of customer information changes in the dimCustomers table.
Move data from the staging tables into the factOrders table as quickly as possible. When creating dimensions for the date keys in the factOrders table, minimize storage space requirements and optimize the cube processing time.
Ensure that queries against the Sales database return the most current data in the data warehouse.
Ensure that the SSAS model of the Finance database does not page to disk or return a memory error as the size of the database grows.
Create an SSAS monitoring solution that tracks the following data:
->Queries answered per second
->Queries from cache direct per second
->Queries from file per second.
Question No: 62 – (Topic 6)
You need to design the dimCustomers table. Which design approach should you use?
Type 2 slowly changing dimension
Type 1 slowly changing dimension
Question No: 63 – (Topic 6)
You need to select the appropriate model type for the Finance database. Which model type should you select?
Tabular with PowerPivot
Question No: 64 – (Topic 6)
You need to implement a strategy for efficiently storing sales order data in the data warehouse.
What should you do?
Separate the factOrders table into multiple tables, one for each month that has orders, and use a local partitioned view.
Separate the factOrders table into multiple tables, one for each day that has orders, and use a local partitioned view.
Create daily partitions in the factOrders table.
Create monthly partitions in the factOrders table.
Question No: 65 – (Topic 6)
You need to create the factCustomerContact table. Which type of table should you create?
A fact table with a non-additive measure
A factless fact table
A periodic snapshot fact table
A fact table with an additive measure
Question No: 66 – (Topic 6)
You need to select and configure a tool for the monitoring solution. What should you choose?
Performance Monitor configured with the MSAS11:Storage Engine Query counter
Performance Monitor configured with the MSAS11:Processing counter
SQL Server Profiler configured with the Query Processing: Query Subcube event
SQL Server Profiler configured with the Queries Events: Query Begin event
Question No: 67 – (Topic 6)
You need to improve the performance of data warehouse queries. What should you do?
Create columnstore indexes.
Create clustered indexes.
Create indexed views.
Create bitmap indexes.
Question No: 68 – (Topic 6)
You need to ensure that you can monitor the usage data.
What should you do?
In SharePoint Central Administration, enable usage data collection.
In the PowerPivot Configuration Tool, repair PowerPivot for SharePoint.
In the PowerPivot Configuration Tool, upgrade PowerPivot for SharePoint.
In Reporting Services Configuration Manager, enable report execution logging.
Question No: 69 – (Topic 6)
You need to ensure that managers can successfully run reports. What should you do?
Implement Kerberos delegation.
Configure the SSRS data sources to store Windows credentials.
Implement forms-based authentication.
Configure the CustomData property in the connection strings.
Question No: 70 – (Topic 6)
You need to configure permissions for the Customers dimension.
What should you do? (Each correct answer presents a complete solution. Choose all that apply.)
In SQL Server Management Studio, configure the BusinessUsers role to disallow the reading of all definitions.
In SQL Server Data Tools, configure the BusinessUsers role to disallow the reading of the Customers dimension definition.
In SQL Server Management Studio, deny the member set for the Customers dimension data by using the Multidimensional Expressions (MDX) expression Filter([BusinessUsers]).
In SQL Server Management Studio, configure the BusinessUsers role to disallow the reading of the Customers dimension definition.
