  5. .asp.vb.net

Show answer
Correct Option: D
Explanation:

To solve this question, the user needs to know about Visual Basic web form code files and their extensions.

The extension for a Visual Basic web form code file is typically ".aspx.vb". This file contains the code-behind logic for a web form created using Visual Basic.

Now, let's go through each option and explain why it is right or wrong:

A. .asp: This extension is used for Active Server Pages, which is a server-side scripting language used to create dynamic web pages. It is not the extension for Visual Basic web form code file.

B. .aspx: This extension is used for Active Server Pages.NET, which is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic web sites, applications and services. It is not the extension for Visual Basic web form code file.

C. .asp.vb: This extension is not typically used for Visual Basic web form code file. It is not the correct answer.

D. .aspx.vb: This extension is the correct answer. This is the extension used for Visual Basic web form code file which contains the code-behind logic for a web form created using Visual Basic.

E. .asp.vb.net: This extension is not typically used for Visual Basic web form code file. It is not the correct answer.

Which property is used to name a web control?
.net

  1. ControlName

  2. Designation

  3. ID

  4. Name

  5. Title

Show answer
Correct Option: C
Explanation:

To solve this question, the user needs to know about web controls and how they are named. Web controls are elements used to interact with a user on a web page, such as buttons, text boxes, or drop-down lists. Each web control needs a unique identifier or name to distinguish it from other controls on the page.

Now, let's go through each option and explain why it is right or wrong:

A. ControlName: This option is incorrect because "ControlName" is not a commonly used property to name a web control. The property used to name a web control is typically something else.

B. Designation: This option is incorrect because "Designation" is not a commonly used property to name a web control. The property used to name a web control is typically something else.

C. ID: This option is correct. The "ID" property is commonly used to name a web control. It provides a unique identifier for the control, which can be used to manipulate or access the control in code.

D. Name: This option is incorrect because "Name" is not commonly used as a property to name a web control. The property used to name a web control is typically something else.

E. Title: This option is incorrect because "Title" is not commonly used as a property to name a web control. The property used to name a web control is typically something else.

The Answer is: C

It is best to use a web instead of a windows application when the application:
.net

  1. has a thin front end (client).

  2. needs to be available to the public.

  3. must be platform-independent.

  4. Both a and b.

  5. All of the above.

Show answer
Correct Option: E
Explanation:

To determine the correct answer, let's go through each option and explain why it is right or wrong:

A. has a thin front end (client): This option suggests that using a web application is best when the application has a thin front end or client. A thin front end typically refers to a minimal user interface that focuses on displaying information rather than performing complex operations. In such cases, a web application can be a suitable choice as it can provide a lightweight and easily accessible interface through a web browser. However, this option alone does not cover all the possible scenarios.

B. needs to be available to the public: This option suggests that using a web application is best when the application needs to be available to the public. Web applications can be accessed over the internet, allowing them to be easily accessible to a wide range of users. This option is valid in scenarios where the application needs to be publicly accessible.

C. must be platform-independent: This option suggests that using a web application is best when the application must be platform-independent. Web applications are typically built using web technologies such as HTML, CSS, and JavaScript, which are supported by most modern web browsers across different platforms. This allows users to access the application regardless of their operating system or device, making it platform-independent.

D. Both a and b: This option combines options A and B, suggesting that using a web application is best when the application has a thin front end (client) and needs to be available to the public. Both of these options are valid reasons to choose a web application, but they do not cover the requirement of being platform-independent.

E. All of the above: This option combines options A, B, and C, suggesting that using a web application is best when the application has a thin front end (client), needs to be available to the public, and must be platform-independent. This option covers all the valid reasons stated in the previous options and provides a comprehensive answer.

Based on the explanations above, the correct answer is:

E. All of the above.

Which is not a fundamental service identified in a three-tier architecture?

.net

  1. Association layer

  2. Connection layer

  3. Logical layer

  4. Both a and b.

  5. All of the above.

Show answer
Correct Option: E

AI Explanation

To answer this question, we need to understand the fundamental services identified in a three-tier architecture.

A three-tier architecture is a software design pattern that divides an application into three interconnected layers: the presentation layer, the application layer, and the data layer. Each layer has its own specific responsibilities and services.

The fundamental services identified in a three-tier architecture are:

  1. Presentation layer: This layer is responsible for presenting the user interface to the user and handling user input. It includes services such as user interface rendering, input validation, and user interaction management.

  2. Application layer: This layer contains the business logic of the application. It handles the processing and manipulation of data, as well as the implementation of business rules. It includes services such as data processing, business logic implementation, and workflow management.

  3. Data layer: This layer is responsible for managing the storage and retrieval of data. It includes services such as data storage management, data access, and database connectivity.

Now, let's go through each option to determine which one is not a fundamental service identified in a three-tier architecture:

Option A) Association layer - This option is not a fundamental service identified in a three-tier architecture. The association layer is not a commonly recognized layer in the three-tier architecture. It may refer to a specific implementation detail or a layer specific to a particular application, but it is not a fundamental service in the context of a three-tier architecture.

Option B) Connection layer - This option is not a fundamental service identified in a three-tier architecture. While connectivity to databases or external services is a requirement in a three-tier architecture, it is typically handled by the data layer, which includes services such as database connectivity and data access. The term "connection layer" is not commonly used to describe a distinct layer in a three-tier architecture.

Option C) Logical layer - This option is a fundamental service identified in a three-tier architecture. The logical layer, also known as the application layer, is responsible for implementing the business logic of the application.

Option D) Both a and b - This option is incorrect because option C is a fundamental service identified in a three-tier architecture.

Option E) All of the above - This option is incorrect because option C is a fundamental service identified in a three-tier architecture.

Therefore, the correct answer is E) All of the above. This option is not a fundamental service identified in a three-tier architecture because both option A (Association layer) and option B (Connection layer) are not commonly recognized layers in a three-tier architecture.

Which layer is exemplified by a web server?

.net

  1. Application

  2. Association

  3. Data

  4. Logical

  5. Presentation

Show answer
Correct Option: A
Explanation:

To solve this question, the user needs to know about the layers of the OSI (Open Systems Interconnection) model, which is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology.

The layer exemplified by a web server is the Application layer, which is responsible for providing network services to the end-user applications. This layer provides services to the software applications that run on top of the network, such as web browsers (e.g., Chrome, Firefox), email clients (e.g., Outlook, Thunderbird), and file transfer clients (e.g., FTP, SFTP).

Now, let's go through each option and explain why it is right or wrong:

A. Application: This option is correct because a web server is an application that provides network services to other applications.

B. Association: This option is incorrect because there is no layer in the OSI model called Association.

C. Data: This option is incorrect because the Data layer is responsible for providing reliable end-to-end transmission of data between two devices.

D. Logical: This option is incorrect because the Logical layer (also known as the Network layer) is responsible for routing data between different networks.

E. Presentation: This option is incorrect because the Presentation layer is responsible for translating, encrypting, or compressing the data into a format that can be understood by the Application layer.

Therefore, the answer is: A. Application.
