You are an enterprise application developer. You create a Microsoft Windows-based service application. The application must perform the following tasks: Monitor running processes for critical events.Log critical events to an e-mail and send the e-mail to the system administrators.Record and include stack information as part of the critical event. You must be able to configure application event logging at run time. Application event logging must have minimal impact on runtime performance. You need to choose an appropriate monitoring feature to
fulfill these requirements. Which feature should you choose?

You are an enterprise application developer. You create a Web-based application and deploy it to your customers. The application requires the users to log on to use the application. The application does not permit impersonation. The application also requires the users to connect to the database and to a folder in the Web server. Your customers report a security bug. The bug denies access to the logged-on users every time they try to upload a file to the folder in the Web server. Your customers provide you with the following data to reproduce the bug: The version of the Web-based applicationThe users steps in the Web-based applicationThe version of the operating system You find that the information is insufficient to reproduce the bug. You need to identify the additional information that is required to reproduce the bug. Which two additional data
should you use? (Each correct answer presents part of the solution. Choose two.)

You are an enterprise application developer. You plan to design a monitoring mechanism for a Web service. The Web service contains a method named Forecast that uses a complex algorithm to forecast weather. The algorithm generates a number of exceptions. Administrators are responsible for shutting down the service when the number of exceptions is greater than 50 for every 10 seconds. You need to monitor the number of exceptions that are generated by the Forecast method during the execution of the Web service. What should you do?

You are an enterprise application developer. You are reviewing a code segment in a Windows Forms application that invokes a Web service asynchronously. You discover that there is no implementation of exception handling. You need to implement exception handling for the application and log the error in the event log by using the minimum amount of coding effort.

You are an enterprise application developer. You are evaluating a component that monitors a Web-based application. The component stores monitoring information in a database and performs the following functions: Retrieves the number of orders placed per second.Tracks the data for peak usage of the application and displays the data in a tabular form. Subsequently, monitoring requirements change in the following manner: Users must be able to view data graphically.Users must be able to analyze data in real time.Users must be able to correlate the number of orders placed per second with the memory usage in the Web server. You need to evaluate whether the component meets the new requirements and propose a solution, if required.

You are an enterprise application developer. The application is used by 500 call center executives for an item tracking system. The existing application contains large custom- serializable business objects that contain no user-specific data. The objects are stored by using the session state in-memory provider. You plan to evaluate the logical design of the application. You need to ensure that the application can support long-term growth in the number of users.

You are an enterprise application developer. You are planning the life cycle of a component. Currently, multiple versions of the component exist. You need to access the most recent version of the component. You also need to ensure that existing applications can access the most recent version and the previous versions of the component without being recompiled. Which plan should
you implement?

You are an enterprise application developer. You develop a component that gathers data from multiple Web services and loads the data into a DataTable. You need to identify a class to persist the information stored in the DataTable to a Microsoft SQL Server database by using the most time-efficient method. Which class should you choose?

You are an enterprise application developer. You are developing a smart client application. You write a method that reads a registry value. Your application runs from a partially trusted environment. The method must not throw an exception when it reads the registry value. You need to ensure that your code is authorized to read the registry key before it attempts to read the value.
What should you do?

You are an enterprise application developer. You are designing an event logging mechanism for a Web-based application. The application uses Windows authentication. The application retrieves data from a Microsoft SQL Server database. The event logging mechanism must meet the following requirements: All logon and logoff events are logged.All exceptions are logged.All access to the database is logged.All application start and end events are logged. You need to ensure that all the requirements are met by using the minimum amount of coding effort. What should you do?
