You are an enterprise application developer. Your company operates a Microsoft Windows-based client application. The application is deployed to 50 client computers on the network. The application uses a separate class library as a data access layer. The data access layer is currently deployed to the application folder of the client application. It is time consuming to deploy new versions of the data access layer. You need to evaluate the current physical design of the application and recommend changes to speed up deployment of new versions of the data access layer.
What should you recommend?

You are an enterprise application designer. You are designing a three-tier enterprise application. The application currently consists of a business layer and a data layer.

The application must perform the following tasks:

Support a smart client interface and a Web client interface. Achieve maximum reuse between the smart client interface and the Web client interface.
Reduce code duplication.

The systems analyst recommends adding a UI layer to perform the required tasks. You need to evaluate this recommendation. What should you conclude?

You are an enterprise application developer. You are evaluating a database design for a human resource application. The existing database schema meets the following criteria:

* The database has an Employee table.
* The Employee table has an Employee ID field and several other fields.
*
You must accommodate the following new requirements:

* Employees are either supervisors or line workers.
* A supervisor will supervise zero or more line workers.
* An employee will be supervised by only one supervisor.

A database administrator suggests creating a table named Supervisor and copying the supervisor data from the Employee table to the new table. The database administrator also wants to create a foreign key in the Supervisor table to reference the Employee table. You need to evaluate the suggested change to ensure that there is minimal impact on the existing database schema.
What should you conclude?

You are an enterprise application developer.
You create an application that has three layers:

* Layer 1 contains the Microsoft Windows client and the input validation logic.
* Layer 2 contains business entities, business workflows, and business rules.
* Layer 3 contains the data access classes and stored procedures.

You need to analyze the layers and identify dependencies that exist between these layers.
Which two dependencies should you identify? (Each correct answer presents part of the solution. Choose two.)

You are an enterprise application developer. You are creating a client/server application. You need to install the application on the company network.
The client/server application must meet the following criteria:

* The server component is a class library that is created by using the .NET Framework.
* The client component is a Microsoft Windows-based application that is created by using the .NET Framework.
* The client component and the server component must communicate by using a binary protocol.
* The fewest possible ports are opened between the client component and the server component.

You need to identify a technology that permits the server to communicate with the client component through the TCP/IP protocol.
Which technology should you use?

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 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 are an enterprise application developer. You create a routing application that ascertains the best routes for shipment of containers.
The application contains a complex routing method that examines the following parameters:

* The weight of the containers
* The length of the trailer that hauls the containers
* Road constraints such as weight limits and bridge heights

The method returns a list of roads to use. You need to design a unit test to ensure that the routes returned do not violate any known constraints.
Which test should you perform?

You are an enterprise application developer. You are testing authentication in a Microsoft Windows-based application.
After the user enters the user name and password in the logon form of the user interface component, the following responses are triggered:

* The user interface component passes the user name and password to a utility component that performs the encryption.
* The user interface component then passes the encrypted user name and password to a Web service.
* The Web service invokes a business component and passes the encrypted user name and password.
* The business component passes the encrypted user name and password to a data access layer component that validates the user.

You need to identify the component on which the business component depends.
Which component should you choose?

You are an enterprise application developer. You create a Web-based application that manages financial transactions for an online investment company. The company requires to meet the following processes:

* Log all customer actions.
* Log all application execution failures.

The company security policy permits audit events to be logged. The security policy requires that there must be only one local administrator on the Web server. The policy also requires that all code must be run with the least possible privileges. The company uses Microsoft Windows Event Log as the repository for all event information. You need to recommend an appropriate solution to meet the companys requirements. You also need to ensure that you adhere to the company security policy.
