You are an enterprise application developer. You are evaluating the physical design of a Web- based application. Fifty customers will use the application from different regions. The use of the application will trigger events of different severities. These events must be logged, extracted, and then filtered on the basis of customer, region, or severity of events. The event details also must be persisted, backed up, and archived for later retrieval. The development team plans to use an event log for logging events. On evaluation, you find the plan does not meet the requirements. You need to explain why an event log fails to meet the requirements.
What should you conclude?

You are an enterprise application developer. You are creating an application that will track shipments. This application must support integration with applications that run on different platforms and operating systems. The application that you are creating can be invoked only through SOAP messages over HTTP. You choose Web services instead of .NET Remoting to meet these requirements. You need to specify the reason for choosing Web services.
Which statement should influence your decision?

You are an enterprise application developer. You are designing an intranet Web application. This application must meet the following requirements:

* The employees must log on to use the application.
* The database authentication mechanism must be as secure as possible.
* The number of connection pools must be minimized.

You decide to use Microsoft SQL Server authentication and a specific SQL Server account. You need to evaluate whether the design will meet the business requirements and make recommendations, if required.
What should you conclude?

You are an enterprise application developer. You are designing an application. The database for the application currently has a one-to-one relationship between order and product. The application must meet the following business requirements:

* An order must contain orders for many products.
* An order must store the ordered quantity of each product.

You need to evaluate the existing design and recommend changes to meet the business requirements.
Which two changes should you recommend? (Each correct answer presents a complete solution. Choose two.)

You are an enterprise application developer. You create a business component for a contact management application that is named Contact. The Contact class contains a public read/write property that is named Company. Company is defined as a string. The Company field in the database is defined as nvarchar(20). You must test whether the property correctly handles values of any length. You decide to use a boundary condition test. You need to evaluate whether the proposed test is appropriate.
What should you conclude?

You are an enterprise application developer. You create an application that consists of a Microsoft Windows service. Your Quality Analysis team finds and reports bugs that occur in the service application. You need to debug your Windows service code to fix the bugs.
What should you do?

You write a Web service that is called by two client applications named Client1 and Client2.

The Web service must return a SOAP header that contains the date and time that the method executed.
You discover that the date and time information for Client1 must be stored in a different XML format from the format used for Client2.
The client application that is making the request is specified as a property of the SOAP header.
You need to ensure that date and time information is stored in the correct format for each client application.
Your solution must not change the way that ASP.NET handles SOAP requests.

What should you do?

You are writing an application that provides a graphical administrative interface to a message queue that displays information about the messages.
The GUI is updated in the AdminFunction function.
You need to ensure that the GUI is updated without unnecessary delay, and that processed messages contain the most recent message contents.

What should you do?

A Windows-based application sends messages to the TestMessageQueue queue.

An acknowledgement message must be sent to the TestMessageQueueAdmin queue when:
The original message is retrieved from TestMessageQueue.
The message has not been retrieved from TestMessageQueue after a specified time period.

The following code is used to send a message to the TestMessageQueue queue.

(Line numbers are included for reference only.)
01 MessageQueue mq = new MessageQueue(“.\\TestMessageQueue”);
02 MessageQueue mqAdmin = new MessageQueue(“.\\TestMessageQueueAdmin”);
03 Message m = new Message(messageBody);
04 m.AcknowledgeType = AcknowledgeTypes.PositiveReceive;
05 mq.Send(m);

You need to ensure that an acknowledgement message is sent to the TestMessageQueueAdmin queue as required.

Which two actions should you perform?(Each correct answer presents part of the solution. Choose two.)

An application has components named ComponentA, ComponentB, and ComponentC.

ComponentA and ComponentB update tables in a database named DB1.
ComponentC updates tables in a database named DB2.
At run time, ComponentA is executed with either ComponentB or ComponentC in a single transaction.
You need to compose the transaction to minimize the use of the system resources.
