Explanation
ARP and ND Suppression are features of ArubaOS-CX that reduce the broadcast traffic on EVPN VXLAN networks. ARP and ND Suppression enable the switch to reply to ARP and ND requests with information present in the local ARP and neighbor cache, instead of flooding them to all VTEPs. This reduces the bandwidth consumption and improves the network performance. ARP- Suppression and ND-Suppression can be enabled or disabled independently. They do not have to be enabled together. Therefore, this statement about ARP and ND Suppression is false, and the correct answer is no. For more information on ARP and ND Suppression, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet3 and the EVPN VXLAN Guide for your switch model.
