This separation allows developers to work on individual components (Model, View, or Controller) without impacting others, leading to more manageable and scalable code. It improves the application's testability and makes it more adaptable to changes, providing a significant advantage over traditional Web Forms.What is the purpose of ViewBag in ASP NET MVC?A) Data transfer between controller and viewB) Database managementC) Error handlingD) URL routingCorrect Answer: A) Data transfer between controller and viewExplanation: ViewBag is a dynamic property provided by the MVC framework used to transfer data from a controller to a view. It's an easy and convenient way to pass data within an MVC application. Unlike ViewData, which requires typecasting, ViewBag automatically achieves this due to its dynamic nature. However, it's important to use it judiciously as it lacks the compile-time checking, making it prone to runtime errors if not handled correctly.Which ASP NET feature is used for reusing a user interface layout across multiple pages?A) Master PagesB) Web PartsC) Custom ControlsD) ThemesCorrect Answer: A) Master PagesExplanation: Master Pages in ASP NET are a powerful feature for maintaining a consistent layout across multiple web pages. By defining a common site template (header, footer, navigation menus, etc.), Master Pages allow content pages to embed their unique content within this shared framework. This not only ensures uniformity across the site but also simplifies maintenance and updates, as changes to the master layout automatically reflect across all associated content pages.In ASP NET, what is the purpose of the Global.asax file?A) Configuring application settingsB) Handling application-level eventsC) Routing URL patternsD) Managing user sessionsCorrect Answer: B) Handling application-level eventsExplanation: The Global.asax file, also known as the ASP NET application file, is used for handling application-level events triggered by ASP NET or by HTTP modules. These events include Application_Start, Application_End, Session_Start, and others. It serves as a central place to manage application-wide events and services, such as logging, error handling, or application initialization tasks. Understanding its role is critical for developers to effectively manage the application lifecycle and response to various global events.Which protocol is primarily used for data transmission in Web API in ASP NET?A) TCPB) HTTPC) FTPD) SMTPCorrect Answer: B) HTTPExplanation: ASP NET Web API primarily uses HTTP for data transmission. It is a framework for building HTTP services that can be accessed from various clients, including browsers and mobile devices. HTTP as a stateless protocol is an ideal choice for RESTful services provided by Web API, where each request is independent and carries enough information on its own. This choice leverages the existing web infrastructure and makes it easy to integrate with web clients using standard HTTP methods like GET, POST, PUT, and DELETE.
