Microsoft TS:MS SQL Server 2008.Business Intelligence Dev and Maintenan Sample Questions:

1. You are an ETL developer for a mortgage company. In your application you have to load data from a Microsoft Excel source and an OLE DB source.
The Excel source contains vender data and has approximately 1000 records.
The OLE source contains loan data and has approximately 1,000,000 records.
Sample vendor data (Excel source) is shown in the following table:
VendorID VendorName 1 VendorA 2 VendorB 3 VendorC 4 VendorD 5 VendorE
Sample loan data (OLE DB source) is shown in the following table:
VendorID VendorName
1 VendorA
2 VendorB
3 VendorC
4 VendorD
5 VendorE
Sample loan data (OLE DB source) is shown in the following table:
LoanNumber VendorID LoanAmount
I-100 1 120000
I-200 1 130000
I-300 2 150000
I-400 3 150000
I-500 4 160000
I-600 4 170000
I-700 5 180000
The CIO asks you to generate an Excel file with the loan list information for each vendor. You build a SQL Server 2008 Integration Services (SSIS) package that can generate the Excel files dynamically. The Excel files should have the vendor name as the prefix and the date as the suffix (e.g., VendorA_DDMMYYYY.xlsx).
You get the error message shown in the exhibit. (Click the Exhibit button.)
You need to sort both sources in order to merge join the data.
What should you do?

A) Set the ISSorted property to True for the OLE DB, sort the data in the selct statement of the OLE DB source, and use sort transformation after the Excel source.
B) Sort the data in the select statement of the OLE DB source and use sort transformation after the Excel source.
C) Use the sort transformation after the OLE DB source and set the IsSorted property to True for the Excel destination.
D) Set the IsSorted property to True for both the OLE DB and Excel sources.

2. You plan to use SQL Server 2008 Integration Services (SSIS) on a SQL Server 2008 failover cluster.
You have a complex package that takes a long time to run.
You need to ensure that if the package executes during a failover, the package can be resumed at the point
of failure.
What should you do?

A) Cluster the SSIS service. Add the SSIS service to its own cluster resource group.
B) Implement checkpoints within your package. Restart the package whenever a failover occurs.
C) Implement transactions within your package. Restart the package whenever a failover occurs.
D) Cluster the SSIS service. Add the SSIS service to the SQL Server cluster resource group.

3. You are developing a SQL Server 2008 Integration Services (SSIS) data flow that extracts data from two sources: a Mircosoft Excel sources and ADO.net. The ADO.net source is based on a SELECT statement that uses an ORDER BY clause.
The data flow is as shown in the following exhibit. (Click the Exhibit button.)
When the paths from the two sources are connected to the Merge Join component, the following error
message is displayed:
Data Flow Task: the input is not sorted. The `input "Merge Join Left Input"(48)' must be sorted.
You need to ensure that data from each query is included in each row in the data flow.
What should you do? (Each correct answer presents part of the solution. Choose two.)

A) Replace the Merge Join transformation with a Union All transformation.
B) Update the sorting properties in the ADO.net source component.
C) Add an OLE DB Command transformation for each data flow.
D) Add a Sort transformation for the Excel source.

4. You create a SQL Server 2008 Analysis Services (SSAS) solution.
You create a dimension named DimCustomer that contains the following three attributes:
Customer
City
Country
The Customer attribute is the key. The DimCustomer dimension is related to a measure group named
Sales
that has the Granularity property set to City.
You need to ensure that you can retrieve measure values based on the City and Country attributes.
What should you do?

A) Set the source attribute to City and the related attribute to Customer. Set the source attribute to Country and the related attribute to Customer.
B) Set the source attribute to City and the related attribute to Customer. Set the source attribute to Country and the related attribute to City.
C) Set the source attribute to Customer and the related attribute to City. Set the source attribute to Customer and the related attribute to Country.
D) Set the source attribute to Customer and the related attribute to City. Set the source attribute to City and the related attribute to Country.

5. You maintain a SQL Server 2008 Analysis Services (SSAS) instance.
You plan to update only the Products dimension while processing the cube by using an XML for Analysis
(XMLA) script.
You need to ensure that only the dimensions are updated.
What should you do?

A) Execute a processIndex command.
B) Execute a processStructure command.
C) Execute a processUpdate command.
D) Execute a processDefault command.
