Nutanix Exam NCS-Core Topic 1 Question 80 Discussion

Actual exam question for Nutanix's NCS-Core exam

Question #: 80
Topic #: 1

A customer wants to ensure that the Data Protection configuration using Protection Domains is fully functional.

The consultant has configured a protection domain for newly-created VMs with static IP addresses on multiple VLANs. The network administrator confirmed that the correct subnets exist at both physical sites.

After performing a failover operation, the virtual machines are turned back on but have no network access.

Which statement describes this issue?

ANetwork mappings are not configured for the Remote Site.

BNutanix Guest Tools (NGT) are mandatory to use Data Protection.

CVirtIO drivers need to be reinstalled after a failover.

DRemote Virtual IP addresses are missing for the Remote Site.

Show Suggested Answer

Suggested Answer: A

If after performing a failover operation the virtual machines have no network access despite the network administrator confirming the correct subnets at both sites, the likely issue is:

A . Network mappings are not configured for the Remote Site: This configuration oversight means that although the VMs are online, they do not have appropriate network settings that correspond to the network environment at the failover site, resulting in connectivity issues.

Aha, the missing Remote Virtual IP addresses must be the culprit. Without those, the VMs have nowhere to call home after the failover.

B: That makes sense, without those addresses, the VMs won't have network access.

But could it also be that VirtIO drivers need to be reinstalled after a failover? That could cause network issues too.

I agree with Chantay, without proper network mappings, the virtual machines won't have network access after failover.

Haha, the VirtIO drivers got scared and ran away during the failover! Time to lure them back with some virtual treats.

Hmm, I don't think it's the NGT issue. The question states the Data Protection configuration is the focus, so the network setup should be the problem here.

I think the issue is that the network mappings are not configured for the Remote Site. The consultant needs to set up the network mappings to ensure the VMs have the correct network access after failover.
