   A cloud provider is using EVPN-VXLAN in its IP fabric to offer Layer 2 connectivity to tenants. A tenant has VMs in two different racks that need to communicate as if they were on the same VLAN. Which component is responsible for encapsulating and decapsulating the tenant traffic?

   • AThe EVPN route reflector, which encapsulates traffic for the overlay.
   • BThe tenant's virtual machines, which must be configured with VXLAN.
   • CThe VTEP (VXLAN Tunnel Endpoint) on the leaf switches.
   • DThe spine switches, which forward the encapsulated traffic.

   A network team is deploying an EVPN-VXLAN fabric. They need to ensure that the overlay control plane can exchange MAC and IP address information between leaf switches. Which protocol is used for this purpose?

   • AMP-BGP with the EVPN address family.
   • BIS-IS with the MAC address family.
   • CPIM-SM for multicast MAC distribution.
   • DOSPF with the VXLAN address family.

   A network engineer is configuring a new IP fabric with 12 leaf switches and 4 spine switches. The design requires fast convergence and the ability to scale to hundreds of leaf switches in the future. The engineer wants to use a single routing protocol for the underlay. Which protocol choice best meets these requirements?

   • AiBGP with a full mesh of sessions between all switches.
   • BeBGP with each leaf and spine using a unique AS number.
   • COSPF with a single area 0 for all switches.
   • DStatic routes pointing to the default gateway on each spine.

   A large enterprise is designing an IP fabric with 40 leaf switches and 8 spine switches. The underlay will use OSPF. The network team is concerned about the OSPF database size and the potential for slow convergence during a spine failure. They are considering splitting the fabric into multiple OSPF areas. What is the most important trade-off to evaluate?

   • AMultiple areas reduce the OSPF database size on each switch but introduce inter-area routing complexity and potential suboptimal paths.
   • BMultiple areas increase the number of BGP peers, which is the primary scaling constraint.
   • CMultiple areas allow the use of different routing protocols in each area, improving flexibility.
   • DMultiple areas eliminate the need for a backbone area, simplifying the design.
