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.
What should you recommend?

You are an enterprise application developer. You are creating an ASP.NET e-commerce Web site. Shoppers are able to browse products anonymously and page output caching is enabled.
You are adding monitoring features to the Web site.
You must track the following information:

* Products that are being browsed
* Promotions that are being clicked on
* Shoppers who want to sign out
* Shoppers who have completed more than one purchase

The monitoring features are in the form of performance counters. You need to ensure that the monitoring features meet the requirements.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are an enterprise application developer. You are creating a Microsoft Windows-based client application that manages investment portfolios and permits users to monitor stock market data. The application must meet the following requirements:

* It must provide asynchronous processing of transactions.
* It must prevent pending transactions from blocking new transactions.
* It must execute transactions immediately.

You need to use an appropriate component implementation approach to meet the requirements.
What should you do?

You are an enterprise application developer. You create a Microsoft Windows client application that consumes a third-party Web service. The Web service is secure and requires user credentials to be passed through SOAP headers. The Web service is currently in its beta. The URL of the Web service will change after it goes live. The beta Web service will be available after the Web service goes live. You need to ensure that the Windows application can switch between the beta version and the live version of the Web service, if required. You need to achieve this goal by using the least maintenance and coding effort.
What should you do?

You are an enterprise application developer. You create a Microsoft Windows-based application for a high-volume call center.
The Windows-based application performs the following tasks:

* The application manages incoming customer calls and requests.
* The application delivers event information to a company server that consolidates the call statistics into reports.

Your design team recommends an event logging solution for the application to meet the following requirements:

* Minimize customer wait times and increase the number of calls that are handled during the workdays.
* Record and log all user activity for historical reporting and auditing.
* Reliably deliver all event information to a central server.
* Consolidate all event information on a central server.

You need to identify a delivery mechanism and a data storage solution for event information.
