You must develop custom business logic to support the reports. The custom business logic has the following requirements:
You must be able to quickly modify and deploy updates to the business logic. You need to develop the custom business logic.
What should you do?
A. Update the report logic to include the custom business logic. Use WebDAV to publish the reports to the server.
B. Develop a new HTTP module that includes the custom business logic. Deploy the HTTP module to IIS.
C. Develop a new HTTP handler that includes the custom business logic. Deploy the HTTP handler to IIS.
D. Develop a new ISAPI filter that includes the custom business logic. Deploy the ISAPI filter to IIS.
Answer: C
Explanation:
An ASP.NET HTTP handler is the process that runs in response to a request that is made to an ASP.NET Web application.
ASP.NET maps HTTP requests to HTTP handlers based on a file name extension.
Incorrect:
Not B: HTTP modules differ from HTTP handlers. An HTTP handler returns a response to a request that is identified by a file name extension or family of file name extensions. In contrast, an HTTP module is invoked for all requests and responses. It subscribes to event notifications in the request pipeline and lets you run code in registered event handlers.

You need to enable client-side validation for an ASP.NET MVC application.

A. Attach a custom validation attribute to the model properties that the view uses.
B. Reference the jquery, jquery.validate and jquery.validate.unobtrusive script files in the view.
C. Open the web.config file at the project root, and set the values of the ClientValidationEnabled and UnobtrusiveJavaScriptEnabled keys to True.
D. For each form element, use the Validator.element() method to validate each item.
E. Add data annotations to the model properties that the view uses.
Answer: B,C,E
Explanation:
B: The validation can be implemented using jQuery and jQuery validation plug-in (jquery.validate.min.js and jquery.validate.unobtrusive.min.js).
C: When you are developing an MVC application in Visual Studio 2012 then the client-side becomes enabled by default, but you can easily enable or disable the writing of the following app setting code snippet in the web.config file.
<configuration>
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
</configuration>
E: The jQuery validation plug-in takes advantage of the Data Annotation attributes defined in the model, which means that you need to do very little to start using it.
New Questions 9
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
