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 design and development of application frameworks. Domain.com operates in the security and surveillance environment. You are currently developing a video surveillance application for Domain.com. While executing your duties, you examine a third party component that implements a Camera class. This class allows you to connect to a physical camera and record video or capture images. The following exhibit illustrates the Camera class definition:

public class Camera
{
public virtual void CaptureImage()
{
//Capture a still image
}
public virtual void StartRecording()
{
//Start a recording session
}
public virtual void StopRecording()
{
//Stop a recording session
}
}

You now need to define the custom class to achieve the following goals:
1. reuse the Camera class to implement a custom class
2. allow the application to capture still images
3. prevent the application from being able to use your class to start and stop a recording session

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 design and development of applications. Domain.com operates as a service provider in the security industry. You are currently developing a video surveillance application for Domain.com. You need to implement a class named Visuals. Visuals will be destined to control access to a video camera. A method named StartRecording must start a recording session of the camera if one is not already started. In the event of a recording session having started already when the method is called, you must interrupt the execution of the application. To this end you now need to define the Visuals class.

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 design and development of applications. Domain.com operates as a Geographic Positioning System service provider. You are currently developing a geographical mapping application. You must create a struct named Waypoint that models a waypoint. This waypoint is to consist of a set of latitude and longitude coordinates. In the event of a user passing a street address to the struct, it must perform a location lookup and set its coordinates appropriately.
To this end you need to define the Waypoint struct. You need to ensure that your application requires the least amount of code to set the coordinates from a street address.

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 design and development of applications. You are currently developing a Microsoft Windows service that will form part of an enterprise solution for Domain.com. The service must be able to (1) Monitor a File Transfer Protocol (FTP) directory for incoming files, and (2) Extract data from the files and import them into a database.
Following are the requirements that should be met by this service:
1. It must run using a least privileged account.
2. It must be capable of processing 300 files per minute.
3. It must be able to recover from failures that cause it to stop functioning. You thus need to identify the factor that is most important during the design of the application.

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. The design of applications forms part of your responsibilities at Domain.com. Domain.com operates as a cosmetics company.
You are currently busy developing an enterprise application for Domain.com. This application must be able to support the ability to access chemical data. This chemical data are stored in five relational databases. The chemical makeup of each product is represented as a business entity. The business logic determines how the chemical makeup can be used in combinations to create new products. You need to evaluate the design in terms of the best performance that is can offer. Following are the physical design aspects that you should take into account in you evaluation:
1. One assembly for all business entities.
2. One assembly to contain business logic.
3. An assembly per type of database.

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. The design of applications forms part of your responsibilities at Domain.com. Domain.com operates as an Internet Service Provider (ISP).
You are currently developing an enterprise application for Domain.com. Domain.com currently offers its customers three services: Web site hosting, Internet connectivity and voice over Internet Protocol (VoIP). The choice of purchasing one or more of these services is up to each customer. Furthermore, multiple customers can purchase the same services. In the event of a customer purchasing a service, a service commencement date, as well as service termination data is set for that customer. The exhibit below illustrates the logical database design for the application.

You now need to normalize the database.

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. The design of applications forms part of your responsibilities at Domain.com. Certkiller .COM operates as an insurance company.
You are currently developing an enterprise application that is destined to allow the Domain.com customer to pay their premiums for the insurance services rendered to them. The Domain.com customers have a choice in payment options: credit card or debit order. In your development of this application you took a decision to model the requirements on a class diagram. You now need to choose the appropriate class diagram.

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 design and development of application frameworks.
A developer named Clive Wilson is currently writing the following code for an Extensible Markup Language (XML) Web service:
(The line numbers are for reference purposes only.)
01 TraceSwitch generalSwitch = new TraceSwitch(“General”, “General Switch”);
02 Trace.WriteLinelf(generalSwitch.TraceError, “Cannot access mainframe computer”);
03 Trace.WriteLinelf(generalSwitch. TraceInfo, “Creating a new data file”);

Unfortunately the Web service is experiencing problems in production. To this end you decide that both the error message and the informational message need to be written to a Microsoft SQL Server 2005 database. Thus a custom trace listener is configured in the Web.config file to write the trace information to the database. Clive Wilson then sets the trace level to 1 (Error). You need to make a decision as to whether the solution is correct or not.

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 design and development of application frameworks. Domain.com operates as a medical technological company that manufactures electronic scanning equipment for medical use. You are currently developing a Microsoft Windows Forms application. This application is destined to allow doctors to perform computed Axial Tomography (CAT) scans on patients. When a CAT scan is carried out, it takes over 1,000 two-dimensional scans that are combined to create a three-dimensional image. It takes no more than two seconds to make a two-dimensional scan, however it also takes approximately 20 seconds to combine each image. The Microsoft Windows Forms application that you are developing must allow doctors to take the two-dimensional scans without requiring the patients to wait for a long time. You thus need to choose the appropriate component to meet this requirement.
