You need to develop a class that implements logging. Which interface should you implement?
A. IExceptionFilter
B. IActionFilter
C. IClientValidatable
D. IResultFilter
Answer: A
Explanation:
Exception filters are used to apply global policies to unhandled exceptions in the MVC app. Exception Filters implement either the IExceptionFilter or IAsyncExceptionFilter interface. Exception filters handle unhandled exceptions, including those that occur during controller creation and model binding. They are only called when an exception occurs in the pipeline.
Question No: 12
You are developing an ASP.NET MVC application to be used on the Internet. The environment does not use Active Directory.
Users must be able to log on to the application to maintain their personal preferences. You need to use the least amount of development effort to enable users to log on. What should you do?
A. Enable Digest authentication.
B. Enable Windows authentication.
C. Enable Forms authentication.
D. Generate server SSL certificates and install them in IIS.
Answer: C
Explanation:
Many Web applications require a way to restrict access to some resources (such as specific pages) so that those resources are accessible only to authenticated users. The default Web application project template for ASP.NET MVC provides a controller, data models, and views that you can use to add ASP.NET forms authentication to your application. The built-in functionality lets users register, log on and off, and change their password. For many applications, this functionality provides a sufficient level of user authentication.
Incorrect:
Not B: Windows authentication would require an Active Directory.
Windows authentication method works only if the following two conditions exist:
/ You set up your network to use the Kerberos authentication protocol that requires Active Directory.
/ You set up the computers and accounts on your network as trusted for delegation. References: https://msdn.microsoft.com/en-us/library/ff398049(VS.98).aspx
