To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) One - This option is incorrect because a single .NET DLL (Dynamic Link Library) can contain multiple classes. A DLL can serve as a container for multiple classes and other types.

Option B) Two - This option is incorrect because a single .NET DLL can contain more than just two classes. It can contain any number of classes, depending on the complexity and design of the software.

Option C) None - This option is incorrect because a .NET DLL must contain at least one class. A class is the fundamental building block of object-oriented programming in .NET, and a DLL must have at least one class definition.

Option D) Many - This option is correct because a single .NET DLL can contain multiple classes. There is no restriction on the number of classes that can be included in a DLL.

The correct answer is D) Many. This option is correct because a single .NET DLL can contain any number of classes.

To answer this question, you need to understand the concepts of Server.Transfer and Response.Redirect.

Option A) Server.Transfer - This option is correct because Server.Transfer is a method in ASP.NET that transfers the execution directly to another page on the server. It preserves the server resources and improves performance by avoiding the round-trip to the client.

Option B) Response.Redirect - This option is correct because Response.Redirect is a method in ASP.NET that redirects the user to a different page or URL. It sends a response to the client with a new URL, and the client's browser makes a new request to that URL. This results in a round-trip to the client.

Option C) Both A) and B) - This option is correct because both Server.Transfer and Response.Redirect transfer the execution directly to another page, but they work in different ways.

Option D) None of the Above - This option is incorrect because both Server.Transfer and Response.Redirect transfer the execution directly to another page.

The correct answer is C) Both A) and B). This option is correct because both Server.Transfer and Response.Redirect transfer the execution directly to another page.

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A: ASP.NET applications run without a Web Server - This option is incorrect. ASP.NET applications cannot run without a web server. ASP.NET is a web development framework developed by Microsoft, and it requires a web server to host and run the applications.

Option B: ASP+ and ASP.NET refer to the same thing - This option is marked as the correct answer. It is incorrect. ASP+ and ASP.NET are not the same thing. ASP+ was a codename used by Microsoft during the early development stages of ASP.NET, but it was later renamed to ASP.NET. ASP.NET is the official name for the web development framework.

Option C: ASP.NET is a major upgrade over ASP - This option is correct. ASP.NET is indeed a major upgrade over ASP (Active Server Pages). ASP.NET provides a more robust and scalable framework for web development compared to ASP. It introduces new features and enhancements, such as improved performance, better security, and support for object-oriented programming.

Option D: None of the above - This option is incorrect. The correct answer is option B, as explained above.

Therefore, the correct answer is option B. ASP+ and ASP.NET do not refer to the same thing.

To answer this question, you need to understand how sessions work in ASP.NET.

In ASP.NET, sessions allow you to store and retrieve user-specific information across multiple requests. Session state is maintained on the server, and a session ID is used to associate the session data with a specific user.

Now let's go through each option to understand why it is correct or incorrect:

Option A) Session.Dump - This option is incorrect. The Session class in ASP.NET does not have a Dump method. Therefore, this option is not a valid way to dump sessions.

Option B) Session.Abandon - This option is correct. The Session.Abandon method is used to abandon or end a session. When you call Session.Abandon, it destroys the session and removes all session data. This effectively "dumps" the session.

Option C) Session.Exit - This option is incorrect. The Session class in ASP.NET does not have an Exit method. Therefore, this option is not a valid way to dump sessions.

Option D) None of the Above - This option is incorrect. As explained above, the correct option is B) Session.Abandon.

Therefore, the correct answer is B) Session.Abandon. This option is correct because calling Session.Abandon will effectively dump the session by destroying it and removing all session data.

To answer this question, we need to understand the concept of reading metadata and using its contents in .NET.

Option A) Reflection - This option is correct. Reflection in .NET refers to the process of examining and manipulating metadata, such as types, properties, and methods, at runtime. It allows you to dynamically inspect and interact with objects and their metadata. Reflection is often used for tasks like invoking methods, accessing properties, and creating instances dynamically.

Option B) Enumeration - This option is incorrect. Enumeration is a different concept in .NET that refers to the process of iterating over a collection of items.

Option C) Binding - This option is incorrect. Binding in .NET refers to the process of connecting data to a user interface element or a property of an object.

Option D) Serialization - This option is incorrect. Serialization in .NET refers to the process of converting an object into a format that can be stored or transmitted, typically as binary or XML data.

The correct answer is A) Reflection. This option is correct because reflection is the operation of reading metadata and using its contents in .NET.

To answer this question, you need to understand the purpose of the DataAdapter control and how it is used to load data into a dataset.

The correct answer is:

B) Fill() - This method is used to populate a dataset with data from a data source. The Fill() method is invoked on the DataAdapter control to fetch data from the database and load it into the dataset. It takes the dataset as a parameter and populates it with the retrieved data.

Option A) Load() - This method is not a valid method for loading data into a dataset using the DataAdapter control. It is not a recognized method in the context of the DataAdapter control.

Option C) DataList - DataList is not a method on the DataAdapter control. It is a type of control used for displaying data in a list format in ASP.NET.

Option D) DataBind - DataBind is not a method on the DataAdapter control. It is a method used to bind data to controls in ASP.NET, but it is not specifically used for loading data into a dataset with the DataAdapter control.

Therefore, the correct answer is B) Fill(). This method is used to load a generated dataset with data from a data source.
