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

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.

The oversubscription ratio in an IP fabric is influenced by the number of spine nodes relative to the number of leaf nodes and their uplinks.

Removing spine nodes reduces available uplink bandwidth, increasing oversubscription.

Adding spine nodes increases available bandwidth between leafs and spines, decreasing the oversubscription ratio.

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.
