You create an application by using Microsoft Visual Studio 2008 and the .NET Framework 3.5.
The application is hosted on a Web server that runs Microsoft Windows Server 2003. It connects to a third-party system by using Web service calls.
The third-party system experiences occasional unplanned outages. When a system outage occurs, the application must perform the following tasks:
– Log error details.
– Notify an on-call technician.
You need to develop a strategy to perform the required tasks.
What should you do?

You create an ASP.NET application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
The application uses a Microsoft SQL Server database. During testing, the application intermittently logs the following exception message:
“Transaction (Process ID xxx) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.”
The error cannot be reproduced in the development environment. You need to identify the root cause of the exception.
What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
The application uses a Web farm to host several Windows Communication Foundation (WCF) services.
The services receive messages from several clients over the Internet that implement the same data contract.
You develop a new version of the data contract. An older version of the data contract had elements that were optional that are now required.
Default element is an acceptable variation for the optional element.Not all customers will be able to implement the new version of the data contract
before you complete deployment to the entire Web farm.You need to define a validation strategy that will ensure that all the clients can successfully
communicate by using the new data contract.
What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application communicates with other systems by using a proprietary messaging format. The company must monitor the response-time of the communication. The monitoring strategy of the application must meet the following requirements:
– Information must be logged to a central location.
– Historical data must not be overwritten without administrator action.
– Information can be displayed in real time.
– Information can be displayed in graphical format.
– Information can be displayed along with system-supplied performance data.
You need to design a strategy that monitors response-times to meet the requirements.
What should you do?

You create a Windows Forms application by using Microsoft Visual Studi .NET 2008 and the .NET Framework 3.5.
The application is installed on several computers on the network.
All unhandled and unexpected exceptions must be logged to a central location to allow reporting for administrator users.
You need to record the exception details. What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. You have a pre-defined database schema.
You plan to design a business object layer in the application. The business object layer must map each database table in the schema to an objectin the layer.
The application must provide support for different database providers.
You need to identify a technology to implement the business object layer by using the minimum amount of development effort.
Which technology should you use?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
You plan to add an existing .NET component into the current application. The .NET component has insufficient documentation.
The structure of the classes in the component must be analyzed before they are incorporated in the application.
You need to analyze the members in the component and the dependencies among them.
What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
The application includes a class that contains several public methods that modify the object state.
Object state is encapsulated in private data members. You need to ensure that your unit tests meet the following requirements:
– Call public methods.
– Validate the expected behavior by checking the values of private data members.
– Fail to compromise object security or encapsulation.
What should you do?

You are designing business layer classes by using the .NET Framework 3.5 and Microsoft SQL Server 2008.
The business classes will be used by a banking application. The class diagram for the business classes is as shown in the exhibit. (Click the Exhibit button.)
You need to ensure that the application meets the following requirements:
– Users are allowed to select only one of the three operationswithdraw, deposit, and get balance.
– Access to other members of the business objects is disallowed.
– Future types of accounts can be handled.
– Use of the operations directly from the class is disallowed.
– Child classes inherited from the business layer classes are prevented from overriding these operations. What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
You purchase a logging component along with the source code from a third-party vendor.
New versions of the component are frequently released by the same vendor.
You require certain additional features that might be present in a future release of the logging component.
You need to consume the logging component in the application.
You also need to ensure that the component can be replaced with a new version by using the minimum amount of development effort.
