Objective 4.2: Design an exception handling strategy
Exceptions are a standard part of applications. Even if your software is error free, your application can throw exceptions or experience other problems due to external factors, such as improper data input or network problems.
As you design your ASP.NET MVC 4 application, you should consider potential problem points, such as calling a web service for data or accessing files on a file share, and determine what you will do when an error occurs. Also consider whether you will notify users and, if so, what you will display in a message. You also need to choose recovery options to keep your application in a normal running state and the kind of diagnostic information you should capture.
