Software Quality Assurance Practice Exam

What aspect of an application is tested by verifying that all links point to valid files or websites?

1. Business layer

2. Data layer

3. Browser compatibility

4. Presentation layer

The correct answer is: Presentation layer

The aspect of an application tested by verifying that all links point to valid files or websites pertains to the presentation layer. The presentation layer is responsible for the user interface and user experience, which includes how information is displayed and how users interact with various elements, such as hyperlinks. Ensuring that all links function correctly and lead to valid destinations is crucial for maintaining a seamless and effective user experience. Testing links relates directly to the visual components of an application, which falls under the presentation layer's domain. A broken link or an incorrect URL can lead to frustration for users, negatively affecting their experience and perception of the application. Therefore, verifying the functionality of links is an essential part of ensuring that the application presents content correctly and effectively to the end-user. In contrast, the other options address different layers of application architecture. The business layer pertains to the logic that processes user inputs and business rules, while the data layer concerns the storage and retrieval of data. Browser compatibility tests focus on ensuring that an application functions correctly across different web browsers, but they do not specifically focus on the validation of links.
