[All HPE2-W09 Questions]

Is this statement about ARP and ND Suppression true?

Solution: The switch replies to ARP requests with information present in the local ARP Table when ARP-Suppression is enabled.

Show Suggested Answer Hide Answer
Suggested Answer: A

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.When ARP-Suppression is enabled, the switch replies to ARP requests with information present in the local ARP Table2. Therefore, this statement about ARP and ND Suppression is true, and the correct answer is yes.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.

LOL, ARP Suppression? More like 'Arp Deception' if the switch is just making up its own replies. Better hope no one's trying to spoof the network!

Hmm, I'm not sure about this one. Isn't ARP Suppression more about reducing unnecessary broadcasts? This answer seems a bit off. I'll have to think it through more.

No way, that can't be right. The switch should forward the ARP request to the intended destination, not reply with its own information. Sounds like a security vulnerability to me!

I'm not sure, but I think the statement is true based on my understanding of ARP-Suppression and how it works.

I disagree, I believe the statement is false because ARP-Suppression actually prevents the switch from replying to ARP requests.

Yes, that's correct! The switch will reply to ARP requests using the information in its local ARP table when ARP Suppression is enabled. Saves a lot of network traffic.
