   A network engineer is implementing a VXLAN-based DCI. They need to ensure that the control plane can advertise MAC addresses to remote VTEPs without relying on data-plane learning. Which protocol should they use?

   • ABGP EVPN
   • BOSPF
   • CIS-IS
   • DPIM

   A company operates two data centers connected by a dark fiber link. They currently run OSPF between the sites to exchange routing information. The network team needs to extend a single VLAN across the link so that a legacy application can perform a live migration of VMs between the sites. They want to avoid purchasing additional hardware. Which interconnect approach should they use?

   • AConfigure VXLAN on the existing routers and extend the VLAN over the IP network.
   • BEnable EVPN on the OSPF routers to advertise the VLAN as a route.
   • CBridge the VLAN directly over the dark fiber using an Ethernet switch at each site.
   • DUse MPLS LSPs to carry the VLAN traffic across the link.

   A large enterprise has two data centers connected via a service provider MPLS VPN. They need to interconnect the two data centers to support active-active workloads that require both Layer 2 and Layer 3 connectivity. The traffic patterns are dynamic, and they want to use traffic engineering to optimize bandwidth utilization. Which interconnect type should they choose?

   • AMPLS-based interconnect with RSVP-TE
   • BIP-based interconnect with BGP
   • CVXLAN-based interconnect over the public internet
   • DDirect dark fiber with Spanning Tree Protocol

   • BTo interconnect two or more geographically separated data centers
   • CTo connect a data center to the internet
   • DTo connect servers within the same rack to a top-of-rack switch
