You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the support and deployment of applications.
Domain.com operates as a credit bureau.
You are currently developing an Extensible Markup Language (XML) Web service that is destined to allow companies to retrieve credit reports from Domain.com. You created a Performance Session in Microsoft Visual Studio 2005 Team Edition for Software Developers. Following are the measurements you obtained from a Web method named ObtainCreditReport:
* When the Web method is called once: execution time for the method is measured to be 8,340.211 milliseconds memory consumption is measured to be 10,200 Kilobytes (K).
* When the Web method is called twice: total execution time for the method is measured to be 33,360.844 milliseconds memory consumption is measured to be 10.296K.
* When the Web method is called thrice: total execution time for the method is measured to be 133,443.376 milliseconds memory consumption is measured to be 10,264 K.
You need to analyze the performance trends.

You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the testing and stabilization of applications.
Domain.com operates as a retailer. You are currently developing a sales management application. You are making use of Microsoft ASP.NET Web and the application will be hosted on a Production Web server that runs Microsoft Internet Information Services (IIS) 6.0. Another Domain.com tester named Rory Allen discovered a bug and reported as follows:
If 30 users access the application simultaneously, an error page is displayed. At present this is unacceptable since Domain.com requirements state that the application should support up to 60 concurrent users. You are thus required to address the issue. To this end you need to reproduce and isolate the bug.

You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the support and deployment of applications. You completed the development of a Microsoft ASP.NET Web application using Microsoft Visual Studio 2005 Team Edition for Software Developers. You then deploy the Microsoft ASP.NET Web application to a production server. Then you discover that the central processing unit (CPU) usage on the Web server sometimes reaches 100%. You then assume that the Web application can be the cause of the sudden increase of CPU usage, but you have no idea of where in the application the problem can be.
You now need to ascertain the reason why this performance spike occurs.

You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the testing and stabilization of applications. Domain.com operates in the international retail environment. Domain.com works in joint ventures with courier companies world-wide due to the nature of the business. These courier companies are responsible for the delivery of the order. A method named Ship is implemented to invoke a Web method of an Extensible Markup Language (XML) Web service at these courier companies. You are currently developing an order fulfillment solution for Domain.com. In this solution, the Domain.com customer’s order is represented by the Order class. The Order class in turn has a Web method named Ship. The Ship method is designed as follows:
1. It accepts a DateTime instance that represents the earliest date that an order should be shipped.
2. It throws an exception if it is passed a data that is earlier than the current date.
3. It allows multiple threads to call it at the same time.
4. It invokes the Web method of the Web service asynchronously.
You are required to unit test and conclude that the previous design aspects are implemented correctly. To this end you need to perform an additional unit test so as to ensure that the Ship method will be functional under all production scenarios.

All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the testing and stabilization of applications. Domain.com operates in the international retail environment. You are currently developing an order fulfillment solution for Domain.com. In this solution, the Domain.com customer’s order is represented by the Order class. The Order class has a property named Status. It is possible to set Status to one of the following enumeration members:
1. Created – the order has been created.
2. BackOrdered – the order has been placed on backorder.
3. Scheduled – the order is scheduled for delivery.
4. Cancelled – the order has been cancelled.
5. Shipped – the order has been shipped.
6. Delivered – the order has been delivered.
Domain.com works in joint ventures with courier companies world-wide due to the nature of the business. A method named Ship is implemented to invoke a Web method of an Extensible Markup Language (XML) Web service at these courier companies. The courier companies are then responsible for the delivery of the order. When the Ship method is called, the Status property is set to Shipped. You are required to unit test the Ship method to ensure that the test passes.

You work as the Microsoft.NET developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. The creation and assessment of serviced components form part of your responsibilities at Domain.com. After receiving the instruction, you complied and have just created a private message queue on an application server. You have configured the message queue in such a way than whenever a message arrives in the queue, you will need to simultaneously run two executables to process the message. To this end you need to create a rule or more rules and triggers to ensure that these two executables run simultaneously when a message arrives in the queue.

You work as the Microsoft.NET developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. The development and deployment of client applications forms part of your responsibilities at Domain.com. You are currently creating a message queue programmatically. This message queue will be accessed by two applications. Each message represents an instance of a public class named OrderInfo. The OrderInfo class does not derive from ServicedComponent, and it does not implement any interfaces. You need to ensure that the state of the class is preserved when a message is sent to and received from the message queue. This state of the class would include the values of private members. The message receiving application understands only the basic .NET Framework classes, and the OrderInfo class. To this end you need to specify the formatter that will be used to serialize and dessserialize messages.

You work as the Microsoft.NET developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. The development and deployment of client applications forms part of your responsibilities at Domain.com. You have received instruction to develop and order fulfillment application. This order fulfillment application must send multiple messages to the queue in the case of it receiving an order. After the application sends the messages to the queue, it must update an inventory database accordingly. In the event of an error occurring for one of the messages while it is busy updating the database, the application must automatically remove all messages that were sent for the current order. In the event of the database update being successful, another application on the same computer must read and process the messages. Only these two applications must be allowed to access the messages.
Now you need to create the message queue manually.
