   A growing company is deploying an IP Clos campus fabric. They currently have 4 spine switches and 20 leaf switches. As the company expands, they expect to add more access switches and users. Which statement correctly describes how the IP Clos fabric scales?

   • AThe fabric size is limited by the number of VLANs, and scaling requires a new fabric.
   • BThe fabric can only scale by replacing existing switches with larger models; adding switches is not supported.
   • CAdding more leaf switches increases the number of endpoints that can connect, while adding more spine switches increases the fabric's capacity and redundancy.
   • DAdding more spine switches reduces the number of leaf switches that can be supported.

   In a campus fabric, what role does EVPN play in the EVPN-VXLAN solution?

   • AIt provides the control plane for signaling MAC and IP routes
   • BIt provides the data plane encapsulation for tenant traffic
   • CIt provides the physical underlay routing protocol
   • DIt provides a management interface for the fabric

   A company is planning to expand its campus fabric from 10 leaf switches to 40 leaf switches. They are concerned about the number of links required and the cost of cabling. Which scaling strategy is most cost-effective while maintaining redundancy?

   • AAdd more spine switches and connect each leaf to all spines, maintaining a full mesh.
   • BConnect each leaf to only two spines to reduce cabling, accepting reduced redundancy.
   • CUse a single spine switch and connect all leaves to it, simplifying cabling.
   • DReplace all leaf switches with larger models that have more ports, avoiding the need for additional spines.

   A network architect is designing an EVPN-VXLAN fabric for a campus with multiple buildings. They need to ensure that broadcast, unknown unicast, and multicast (BUM) traffic is handled efficiently without flooding the entire fabric. Which approach should they use?

   • AUse a central server to handle all BUM traffic and forward it to the appropriate leaves.
   • BUse multicast in the underlay to efficiently distribute BUM traffic to all leaves.
   • CUse EVPN with ingress replication, where the ingress leaf replicates BUM traffic to all other leaves in the VNI.
   • DDisable BUM traffic entirely and rely on unicast for all communication.

   What is a key consideration for cabling in an IP Clos campus fabric deployment?

   • AUse wireless links for spine-to-leaf connections to simplify cabling
   • BEnsure that leaf-to-spine links use appropriate fiber types and speeds for the distance
   • CUse only copper cabling for all leaf-to-spine links to reduce cost
   • DUse a single cable type for all links to reduce inventory
