Match each network topology architecture model or functional layer on the left to its corresponding design trait and operational responsibility on the right.
- Collapsed Core Architecture LayerCombines core transport and policy enforcement into a single redundant switch pair to reduce cost and complexity in small-to-medium enterprise sites.
- Three-Tier Core LayerProvides high-speed, uncompromised L2/L3 transport without performing CPU-intensive packet inspection, ACL filtering, or policy enforcement.
- Three-Tier Distribution LayerAggregates Access switches, acts as the Layer 2/Layer 3 boundary, and enforces security policies, QoS markings, and inter-VLAN routing.
- Data Center Spine Layer (Clos)Functions as a high-bandwidth IP fabric backbone where every leaf switch connects to every switch in this tier with predictable single-hop latency.
Answer
Collapsed Core Architecture Layer matches the description combining core transport and policy enforcement into a single switch pair. Three-Tier Core Layer matches the description providing high-speed transport without CPU-intensive packet inspection or ACL filtering. Three-Tier Distribution Layer matches the description aggregating Access switches, acting as the L2/L3 boundary, and enforcing security policies. Data Center Spine Layer matches the description functioning as a high-bandwidth IP fabric backbone with predictable single-hop latency.
Each architecture layer is uniquely optimized for its operational domain: Collapsed Core combines distribution and core functions for smaller networks; Three-Tier Core optimizes raw forwarding speed without packet filtering; Three-Tier Distribution acts as the control boundary for VLANs, security policies, and routing aggregation; Spine-Leaf Spine nodes provide predictable, non-blocking single-hop transport between all leaf switches.
