You use the Task.Run() method to launch a long-running data processing operation. The data processing operation often fails in times of heavy network congestion.If the data processing operation fails, a second operation must clean up any results of the first operation.You need to ensure that the second operation is invoked only if the data processing operation throws an unhandled exception.What should you do?
You are modifying an application that processes leases. The following code defines the Lease class. (Line numbers are included for reference only.)Leases are restricted to a maximum term of 5 years. The application must send a notification message if a lease request exceeds 5 years.You need to implement the notification mechanism.Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
You are developing an application that uses structured exception handling. The application includes a class named ExceptionLogger.The ExceptionLogger class implements a method named LogException by using the following code segment: public static void LogException(Exception ex)You have the following requirements:✑ Log all exceptions by using the LogException() method of the ExceptionLogger class.✑ Rethrow the original exception, including the entire exception stack.You need to meet the requirements.Which code segment should you use?
You are developing an application that includes a class named UserTracker. The application includes the following code segment. (Line numbers are included for reference only.)You need to add a user to the UserTracker instance.What should you do?
DRAG DROP -You develop an application that displays information from log files when errors occur. The application will prompt the user to create an error report that sends details about the error and the session to the administrator.When a user opens a log file by using the application, the application throws an exception and closes.The application must preserve the original stack trace information when an exception occurs during this process.You need to implement the method that reads the log files.How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)Select and Place:
You are developing an application that includes a class named Order. The application will store a collection of Order objects.The collection must meet the following requirements:✑ Use strongly typed members.✑ Process Order objects in first-in-first-out order.✑ Store values for each Order object.✑ Use zero-based indices.You need to use a collection type that meets the requirements.Which collection type should you use?
