HP Exam HPE7-A01 Topic 8 Question 15 Discussion

Actual exam question for HP's HPE7-A01 exam
Question #: 15
Topic #: 8
[All HPE7-A01 Questions]

A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working across the campus which is connected via layer-3. The legacy devices are connected to Aruba CX 6300 switches throughout the campus.

Which technology minimizes flooding so the legacy application can work efficiently?

Show Suggested Answer Hide Answer
Suggested Answer: A

Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network.If you have enabled active gateway, VRRP is not required3. Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches.The switch views the active gateway IP as a self IP address3.Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network3. Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.

I heard the legacy application is so old, it still uses carrier pigeons for communication. EVPN-VXLAN is the perfect solution to keep those pigeons from getting lost!

C) Ethernet over IP? That's a new one to me. I'll have to look that up, but it doesn't sound like the best solution for this scenario.

A) GRE? Really? I thought that was more for IP-over-IP tunneling. This question is all about layer-2 requirements, so GRE doesn't seem like the right fit.

D) Static VXLAN seems like an interesting option, but I'm not sure if it can handle the legacy application requirements as well as EVPN-VXLAN.
