A network uses on pair of Layer 3 switches for core and distribution purposes. Which design is this network using?

In a collapsed core architecture, the core and distribution layers are combined into a single layer of Layer 3 switches, eliminating a separate core tier. This is common in smaller networks where the full three-tier model (core, distribution, access) is unnecessary. The pair of Layer 3 switches handles both routing and high-speed switching functions normally split across two tiers.

Collapsed distribution is not a standard network design term - the recognized term for merging these two layers is collapsed core.

Collapsed Layer 3 core is not a standard Cisco hierarchical design term and does not accurately describe the merging of core and distribution functions.

Collapsed Layer 2-3 is not a recognized hierarchical network design term and does not describe the specific combination of core and distribution layers.
