Which option correctly describes a two-tier network design?
Options:
A.
designed to avoid routing entirely and to have Layer 2 remain across Core, Distribution, and Access layers
B.
divides the Core into two layers (Core and Aggregation) with the Access Layer only handling PoE and Access Control
C.
includes a Distribution Layer to provide Layer 3 features between a routed Core and a Layer 2 Access edge
D.
divides the network into two layers (Access and Core) with the option of routing to the Access Layer
Answer
C
Explanation
In a two-tier network architecture, the collapsed core layer typically combines the core and distribution layers of a three-tier architecture into a single layer. The main function of the collapsed core layer is to provide high-speed switching and routing of traffic between the distribution layer switches and the access layer switches.
