A network engineer is tasked with enhancing the efficiency and manageability of a growing corporate network. The current flat network architecture leads to high latency and challenging troubleshooting. The engineer decides to implement a three-tier hierarchical network design. What layer of the three-tier model is primarily responsible for connecting users and providing them access to network resources?
The Access layer is the correct answer because it connects devices to the network and directly interfaces with end-users, providing them with access to the network resources. The Distribution layer, often mistaken as the correct answer, aggregates the data received from the Access layer before it is transmitted to the Core layer for routing to other network segments. The Core layer is designed for high-speed, efficient data transport across the network backbone and is not involved in directly connecting end-user devices.
