[Configure and Utilize Nutanix Unified Storage]
An administrator has recently added several NGT-enabled VMs with in-guest iSCSI initiators to a Volume Group (VG) using IP addresses in the VG allowlist. Several days later, the administrator restored the VG, after which the VMs lost connectivity to the Volume Group.
What should the administrator have done differently to prevent this from happening?

Agreed, it’s more reliable for iSCSI connections.

I think using the iSCSI IQN is the best option.

A covers all bases. IQN is standard practice.

D is too specific. MAC addresses can change too.

C seems risky. Hostnames can change.

I agree, but B could work too. VM UUID is unique.

I think option A is the best choice. IQN is crucial for iSCSI.

I thought IP addresses were enough, guess I was wrong!

Using MAC addresses is a solid option too, just saying.

Wait, can you really use VM UUIDs for this? Sounds odd.

I vaguely recall something about MAC addresses being less reliable for this kind of configuration. I wonder if the IQN is really the best practice here.

I feel like using the VM hostname could lead to issues if the hostname changes, so I'm leaning towards the iSCSI IQN option.

I'm not entirely sure, but I think the VM UUID could also work since it uniquely identifies the VM. It might have been mentioned in one of the practice questions we did.

I remember we discussed the importance of using the correct identifiers in the allowlist during our practice sessions. I think using the iSCSI IQN might be the right choice here.
