CompTIA Network+ Practice Test

Which of the following best describes the access layer of a three-tier architecture?

1. Connects web servers to the users

2. Midpoint for traffic management

3. Direct connection point for workstations and printers

4. Handles data storage and processing

The correct answer is: Direct connection point for workstations and printers

The access layer of a three-tier architecture is primarily responsible for providing end-user devices with a direct connection to the network. This includes connecting workstations, printers, and other endpoint devices, enabling them to communicate with the services provided by the upper layers. As such, it functions as the point where users access the network, facilitating their ability to send and receive data. In a three-tier architecture, the access layer plays a crucial role in managing how users interact with the network. It is designed to efficiently deliver user traffic to the network and is focused on providing access to resources and services rather than managing the heavy lifting of data processing or storage, which is typically handled by the higher layers. This differentiation makes it clear why this description fits the access layer best. The other choices refer to different functionalities within a three-tier architecture. For instance, connecting web servers to users relates more to the presentation layer, while a midpoint for traffic management suggests functions that fall under the distribution layer, which is responsible for routing and managing traffic between the access and core layers. Lastly, handling data storage and processing is characteristic of the core layer, where back-end resources are managed. Thus, the description that emphasizes a direct connection point for workstations and printers aligns accurately with the role
