Which layer of the three-tier hierarchical network model typically manages routing between VLANs, aggregates uplinks from access switch layers, and enforces security policies?
Core
Collapsed Core
Distribution
Access
The correct answer is the Distribution layer. This layer aggregates the data received from the Access layer switches and forwards it to the Core layer or routes it between different VLANs. It is crucial in managing the routing between VLANs, which involve inter-VLAN routing and Layer 3 forwarding decisions. This layer can also enforce security policies through access control lists (ACLs) and firewall policies, shaping and controlling the boundary between the high-speed backbone connectivity of the Core layer and endpoint data traffic management in the Access layer. Core layer mainly handles high-speed packet switching across the network backbone without focusing on inter-VLAN routing, making it an incorrect option. Access layer focuses on connecting endpoint devices to the network and does not handle inter VLAN routing or enforcement of security polices. Collapsed Core is an architecture where the Core and Distribution layers are combined; however, the question specifically asks about the traditional three-tier model.
