You are an enterprise application developer. You are creating a component that will be deployed as part of a class library. The component must meet the following specifications:

The interface of the component must be accessible to components outside the hosting assembly.
The interface of the component must be interoperable with components written in any other .NET Framework languages.
The implementation of the component cannot be expanded upon by a derived class.

You need to design the interface of the component.
Which three tasks should you perform? (Each correct answer presents part of the solution.
Choose three.)

You are an enterprise application developer. You are creating a .NET Remoting component. The Version 1.0 of the component is deployed as a well-known server-activated object. The strong- named component is installed into the global assembly cache. Ten distributed applications in your
company utilize the component, and each application has an independent schedule for upgrades and deployment. You add new features to the component. These additions will change the signatures of the public methods on the component. You need to devise a deployment strategy for the component. What should you do?

You are an enterprise application developer. You are designing an event logging mechanism for a Web service. The Web service will be used to expose financial data. You need to ensure that the event logging mechanism meets the following requirements: Access to all financial data is logged in production for auditing purposes.Arithmetic exceptions are logged only during application development.Event log data is available to the administrators only on the local Web servers. Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)

You are an enterprise application developer. You create a three-tier Web-based application that accesses 10 external Web services to retrieve currency rates. You need to calculate product prices in ten currencies. A smart client invoicing application accesses the business tier to retrieve and use the product prices in 10 currencies. The business tier calls the 10 external Web services. You create a separate service agent component to encapsulate the logic of which Web service to call. This component also makes it easier to change the Web references when required. Your team plans to deploy this service agent in the Web presentation tier. You need to evaluate whether your teams deployment plan meets the requirements and recommend accordingly. What should you conclude?

You are an enterprise application developer. You are implementing a new component for an application. The component accesses a database to populate a list of customer objects and exposes a method that is named GetAllCustomers. The component uses a design pattern to access the database only on an as-needed basis. A caching mechanism exists in a lower tier of the application architecture. The component must not cache data. You need to implement the logic for populating a list of customer objects by using a database query. You also need to ensure that you meet the company guidelines for the component design pattern. What should you do?

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 designing an application that manages names and descriptions for your companys products.
To manipulate these items, the application requires the object that holds the strings to meet the following criteria:

Be dynamically resizable.
Be able to store duplicate entries.
Expose methods to find all instances of the same text.

You need to recommend an appropriate container for the strings. What should you recommend?

You are an enterprise application developer. You are designing unit tests for a Customer class.
The Customer class contains properties to get or set data in private fields. The Customer class
also contains one default constructor and one non-default constructor. The non-default constructor accepts a Customer ID argument. When the non-default constructor is used to instantiate the Customer object, a public method named Load is invoked along with the Customer
ID argument. The Customer object properties are then loaded by using values from the database.
You need to design unit tests that will test the class properties. Which three test scenarios should
you recommend? (Each correct answer presents part of the solution. Choose three.)
