What is one use case for designing a 2-tier campus LAM instead of using a 3-tier?
A
Explanation:
A 2-tier campus LAN architecture, consisting of the core and access layers, is typically suitable for
smaller campuses or networks with limited numbers of wiring closets. This simplified architecture
eliminates the need for a dedicated aggregation layer, which is more common in larger, more
complex network environments (the 3-tier architecture). In a small campus setting with only a few
wiring closets, a 2-tier design can provide sufficient performance and scalability, reducing complexity
and potentially lowering costs. This architecture allows for direct connectivity between the access
layer, where end devices connect to the network, and the core layer, which routes traffic to and from
the campus network. The use of a 2-tier architecture in such scenarios is driven by the network's size
and the simplicity of its requirements, making it an efficient and effective choice.
