MCSD-Microsoft Certified Solutions Developer Questions

Q:

You are a Web developer for XYZ. You create an ASP.NET application that accesses sales and marketing data. The data is stored in a Microsoft SQL Server 2000 database on a server named XYZ01.


The company purchases a factory automation software application. The application is installed on XYZ01, where it creates a second instance of SQL Server 2000 named Factory and a database named FactoryDB. You connect to FactoryDB by using Windows Integrated authentication.


You want to add a page to your ASP.NET application to display inventory data from  FactoryDB. You use a SqlConnection object to connect to the database. You need to create a connection string to FactoryDB in the instance of SQL Server named Factory on XYZ01. Which string should you use?

A) ?Server=XYZ01;Data Source=Factory; Initial Catalog=FactoryDB;Integrated Security=SSPI? B) ?Server=XYZ01;Data Source=Factory; Database=FactoryDB;Integrated Security=SSP1?
C) ?Data Source=XYZ01\Factory; Initial Category=Factory; Integrated Security=SSP1? D) ?Data Source=XYZ01\Factory; Database=FactoryDB; Integrated Security=SSP1?
 
Answer & Explanation Answer: D) ?Data Source=XYZ01\Factory; Database=FactoryDB; Integrated Security=SSP1?

Explanation:

The Data Source attribute of the connection string contains the name, instance or network address of the instance of SQL Server to which to connect. In this scenario we are to connect to the Factory Instance on XYZ01 so we use XYZ01\Factory as data source. To specify the database we should either use the Database or the Initial Catalog attribute. Here we use Database=FactoryDB.

 

Incorrect Answers:

 

A, B: There is no Server attribute in the connection string. Instead we should use the Data Source attribute to specify the server and the instance.

 

C: There is no Initial Category attribute in the connection string. We can use Database or the Initial Catalog attribute to specify the database.

Q:

You are creating an ASP.NET application for XYZ. The company data is stored in a Microsoft SQL Server 6.5 database. Your application generates accounting summary reports based on transaction tables that contain million of rows.


You want your application to return each summary report as quickly as possible. You need to configure your application to connect to the database and retrieve the data in a away that achieves this goal.


What should you do?

A) Use a SqlConnection object to connect to the database, and use a SqlCommand object to run a stored procedure that returns the data. B) Use an OleDbConnection object to connect to the database, and use an OleDbCommand object to run a stored procedure that returns the data.
C) Configure SQL Server to support HTTP access, and create an XML template to run a stored procedure that returns the data in XML format. D) Use COM interop to create an ADODB.Connection object, and use an ADODB.Command object to run a SQL statement that returns the data.
 
Answer & Explanation Answer: B) Use an OleDbConnection object to connect to the database, and use an OleDbCommand object to run a stored procedure that returns the data.

Explanation:

We need to use an OleDBConnection to connect to SQL Server Version 6.5 (or earlier). 

 

Incorrect Answers:

 

A: We could use a SqlConnection object only if the SQL Server were SQL Server 7.0, 2000 or later.

 

C: HTTP functionality is not required in this scenario. It would introduce unnecessary overhead.

 

D: ADODB is a legacy standard and should not be used here

Q:

You create English, French, and German versions of a test engine ASP.NET application you are developing for XYZ Inc. You have separate resource files for each language version.You need to deploy the appropriate resource file based on the language settings of the server. What should you do?

A) Create an installer and set the Installer.Context property for each version of your application. B) Create an installer that has a launch condition to verify the locale settings.
C) Create an installer that has a custom action to install only location-specific files. D) Create an installer that has an MsiConfigureProduct function to install the appropriate version.
 
Answer & Explanation Answer: C) Create an installer that has a custom action to install only location-specific files.

Explanation:

Custom actions are a Windows Installer feature that allows you to run code at the end of an installation to perform actions that cannot be handled during installation. This is an appropriate solution for this scenario as we only want to deploy the resource files on the server. 

 

Incorrect Answers:

 

A: We just want to deploy the resource files. We do not need to set the Context property in the application.

 

B: We don’t need any launch conditions. We just want to deploy the resource files.

 

D: We just want to deploy the resource files.
