Question
SIMULATION VLAN 40 is configured in Switch A with an anycast-address of 192.168.40.254/24. The ARP neighbor suppression is enabled. Use the simulator to create a VTEP named vtep1 and assign an IP address of 10.10.10.1. Map the VNI 400 to VLAN 40. Answer:
Enter Configuration Mode:
SwitchA# configure terminal Create VTEP Interface:
SwitchA(config)# interface vtep1 SwitchA(config-if-vtep1)# ip address 10.10.10.1/24 SwitchA(config-if-vtep1)# exit Map VNI 400 to VLAN 40:
SwitchA(config)# vlan 40 SwitchA(config-vlan)# vn-segment 400 SwitchA(config-vlan)# exit Enable ARP Neighbor Suppression:
SwitchA(config)# interface Vlan40 SwitchA(config-if-Vlan40)# ip address 192.168.40.254/24 SwitchA(config-if-Vlan40)# vxlan arp-suppression SwitchA(config-if-Vlan40)# exit Save Configuration:
SwitchA# write memory

Explanation
Option A is correct because it follows the exact sequence required to configure a VXLAN environment: creating the VTEP interface with its underlay IP, binding the VNI to the VLAN via vn-segment, then configuring the VLAN interface with the anycast gateway address and enabling ARP suppression - each step is a prerequisite for the next. The order matters critically: you cannot map a VNI to a VLAN that has no segment defined, and ARP suppression must be applied on the SVI (Switched Virtual Interface) after the anycast address is set. Since this appears to be a single-answer simulation question, any variation that omits a step, uses wrong syntax (e.g., vni instead of vn-segment), or applies commands out of order would break the configuration.
Memory tip: Think of the acronym IVMS - Interface (VTEP) → VNI mapping → make the SVI → Suppress ARP - to remember the correct order of VXLAN configuration steps on exam simulations.
