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.

Reducing the oversubscription ratio means provisioning more uplink bandwidth relative to access bandwidth, which improves congestion handling and performance but also increases network cost due to the need for additional or higher-capacity links and equipment.

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.
