JN0-1103 Exam Dumps : Design - Associate (JNCIA-Design)

The exhibit shows a hierarchical structure with Leaf, Spine, and Super Spine layers. This architecture is characteristic of a 7-stage IP fabric, which is used in large-scale data centers to provide high scalability and bandwidth. It extends the 3-stage fabric by adding an additional spine layer (Super Spine) for interconnecting multiple spine layers.

VXLAN and MPLS are commonly used to encapsulate frames and provide Layer 2 reachability across an IP fabric. VXLAN enables L2 overlays over L3 infrastructure, while MPLS can also be used in L2VPN services to extend L2 connectivity across IP/MPLS networks.

Planned outages (for maintenance or upgrades) and WAN failures (due to carrier or link issues) both directly impact network uptime by causing service disruptions, either scheduled or unexpected.
