Is this statement about ARP and ND Suppression true?

Solution: ARP-Suppression and ND-Suppression must be enabled together.

Show Suggested Answer Hide Answer
Suggested Answer: B

ARP and ND Suppression are features of ArubaOS-CX that reduce the broadcast traffic on EVPN VXLAN networks1.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 VTEPs1.This reduces the bandwidth consumption and improves the network performance1.ARP-Suppression and ND-Suppression can be enabled or disabled independently1.They do not have to be enabled together1. 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 datasheet3and the EVPN VXLAN Guide for your switch model1.

I see the rationale, but I still think we should be able to choose whether to enable one or both.

But the solution clearly states that both must be enabled. It helps in preventing unnecessary ARP and ND requests.

I think they should be enabled together because they both prevent address resolution conflicts.
