   A network architect is comparing EVPN-VXLAN with traditional VLAN trunking for a data center. The architect needs to justify the migration by highlighting a key operational benefit. Which statement accurately describes an operational advantage of EVPN-VXLAN?

   • AIt reduces the number of VLANs required on access ports.
   • BIt eliminates the need for STP by using BGP for loop prevention.
   • CIt increases the MTU size of the underlay.
   • DIt simplifies the underlay by removing the need for IP routing.

   A network team is designing an EVPN-VXLAN fabric. They have two options: use EVPN to advertise MAC routes, or rely on traditional data-plane learning. The team is concerned about the amount of BGP updates in the network. Which statement correctly compares the control plane overhead?

   • AEVPN increases control plane traffic but provides faster convergence.
   • BEVPN eliminates the need for BGP by using OSPF for MAC advertisement.
   • CEVPN generates more control plane traffic than data-plane learning because it advertises every MAC.
   • DEVPN reduces control plane traffic by using BGP route aggregation.

   In a multi-tenant data center, how does EVPN-VXLAN help isolate tenant traffic?

   • ABy using a separate routing protocol for each tenant
   • BBy encrypting each tenant's traffic with a different key
   • CBy using a unique VNI for each tenant's Layer 2 segment
   • DBy assigning each tenant a different physical switch
