   A network architect is designing an IP fabric and must decide where to invest in scaling. The current underlay has sufficient bandwidth, but the overlay is expected to grow significantly in the number of tenants and MAC addresses. Which scaling approach should they prioritize?

   • AScale the overlay by deploying EVPN and using route targets for tenant isolation.
   • BScale the underlay by using BGP confederations.
   • CScale the underlay by adding more spine switches.
   • DScale the underlay by enabling ECMP on all links.

   A company is designing a leaf-spine fabric for a web-tier workload that has unpredictable east-west traffic patterns. They want to maximize bandwidth utilization while keeping the design simple. Which design consideration is most important to achieve this goal?

   • AUse a single spine switch to reduce latency.
   • BDeploy EVPN-VXLAN on the underlay.
   • CConfigure all leaves in a single BGP autonomous system.
   • DEnsure all leaf-to-spine links are the same speed and use ECMP.

   An enterprise is deploying a VXLAN EVPN fabric to support multiple tenants. Each tenant requires Layer 2 adjacency across many leaf switches. The network team wants to scale the number of tenants without increasing the number of VLANs or subnets. Which EVPN feature directly enables this scaling?

   • ABGP route reflection for EVPN routes.
   • BRoute targets and route distinguishers to isolate tenant routes.
   • CSpine-and-leaf oversubscription design.
   • DECMP on the underlay to load-balance VXLAN traffic.

   Why is monitoring important when scaling an IP fabric?

   • ATo reduce the number of network devices required
   • BTo eliminate the need for regular maintenance
   • CTo automatically configure new switches without manual intervention
   • DTo detect and troubleshoot issues such as link failures, congestion, and routing anomalies

   What role does ECMP play in providing redundancy in an IP fabric?

   • AIt uses a single path but with redundant hardware
   • BIt ensures that all paths are always active and traffic is automatically rerouted if one path fails
   • CIt prevents any single point of failure by duplicating all traffic
   • DIt creates a backup path that is used only when the primary path fails
