Match each network architecture layer or topology design model on the left to its correct functional responsibility or operational trait on the right.
- Spine Layer (Data Center Spine-Leaf)Acts as a high-speed L3 backbone interconnecting nodes without direct peer-to-peer links, enabling equal-cost multipath (ECMP) forwarding.
- Leaf Layer (Data Center Spine-Leaf)Serves as the network boundary where endpoints connect, acting as the VXLAN Tunnel Endpoint (VTEP) for encapsulation.
- Distribution Layer (Traditional 3-Tier Campus)Provides policy-based routing, inter-VLAN routing, ACL filtering, and QoS enforcement between access switches and core infrastructure.
- Collapsed Core Layer (2-Tier Campus)Consolidates high-speed transport routing and policy control functions into a single physical switch tier for smaller enterprise sites.
Cevap
Spine Layer matches high-speed L3 ECMP backbone forwarding; Leaf Layer matches endpoint attachment and VTEP encapsulation; Distribution Layer matches inter-VLAN routing, ACL filtering, and policy enforcement; Collapsed Core matches combining Core transport and Distribution policy into a single switch tier.
The pairings correctly align each tier with its defining design attributes: Spine switches provide non-blocking ECMP L3 transport; Leaf switches act as endpoint connection points and VTEPs; Distribution switches manage L2/L3 policy, ACLs, and routing boundaries; Collapsed Core switches combine Core and Distribution capabilities into one physical tier.
