Software Quality Assurance Practice Exam

Select the description that matches the e-commerce architecture tier for tier 1:

1. Focuses on storing and retrieving data from the data source

2. Provides the visual content to the end user

3. Runs the software to model user business processes

4. Handles payment processing

The correct answer is: Provides the visual content to the end user

The description that aligns with tier 1 of e-commerce architecture accurately identifies the function of the presentation layer. This tier is responsible for providing the visual content and user interface through which end users interact with the application. It encompasses the design aspects that users engage with, including layouts, graphics, and overall user experience elements. The primary goal of this tier is to ensure that users can efficiently navigate the platform and access the features provided by the e-commerce application. The other tiers focus on different aspects of the e-commerce system. For instance, the data tier would be concerned with storing and retrieving data, while the logic tier would manage the underlying processes and workflows required to fulfill business transactions. The specific duty of handling payment processing would typically be part of the business logic tier or a separate service dedicated to transactions, rather than the presentation tier.
