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

For a 120-meter (400-foot) connection between switches, multimode fiber is the most reliable and cost-effective option. It supports higher bandwidth and longer distances than UTP (which is limited to 100 meters) and is more stable and secure than a wireless solution.

BGP multipath with multiple-as is required in an EBGP underlay to enable ECMP across multiple autonomous system paths. In an IBGP underlay, Route Reflectors help scale the control plane by reducing the need for a full mesh of BGP sessions among all fabric nodes.

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.
