Cisco 300-620 Exam - Topic 5 Question 76 Discussion

A Cisco ACI environment consists of multiple silent hosts that are often relocated between leaf switches. When the host is relocated, the bridge domain takes more than a few seconds to relearn the host's new location. The requirement is to minimize the relocation impact and make the ACI fabric relearn the new location of the host faster. Which action must be taken to meet these requirements?
A) Set Unicast Routing to Enabled.
B) Configure ARP Flooding to Enabled.
C) Set L2 Unknown Unicast to Hardware Proxy.
D) Configure IP Data-Plane Learning to No.

Unicast Routing being enabled sounds like a solid option too!

I feel like configuring IP data-plane learning to 'No' could slow things down, but I'm not confident about how it affects the relearning process.

I practiced a similar question where enabling unicast routing was the answer, but I don't know if it applies here since the focus is on host relocation.

I think the hardware proxy option might be related to how the ACI fabric handles unknown unicast traffic, but I can't recall the exact impact on learning speed.

I remember something about ARP flooding helping with faster host relocation, but I'm not entirely sure if it's the best option here.

I'm pretty confident I know the right answer here. The question is specifically asking how to make the ACI fabric relearn the host's new location faster, so the obvious choice is to configure ARP Flooding to Enabled. That will ensure the fabric gets updated as soon as the host moves.

Okay, I think I've got this. The key is to minimize the relocation impact and make the fabric relearn the host's new location faster. Based on that, I'd say the best option is to set L2 Unknown Unicast to Hardware Proxy. That should help the fabric learn the new location more quickly.

Hmm, I'm a bit confused by the question. I'm not super familiar with the ACI environment and the different settings they're asking about. I'll need to review my notes on this topic before attempting to answer.

Hmm, I'm not sure about this one. Reformatting the hard drive or deleting the active partition seem a bit extreme. I think I'll try the Disk Cleanup tool first before considering anything more drastic.

I bet the person who wrote this question has been relocating hosts between leaf switches all day. That's the only way they could come up with something this devious!
