Discuss Nutanix NCP-MCI-6.10 Exam Topic 3 Question 9

A company is evaluating Nutanix Disaster Recovery (DR) to protect multiple business-critical applications. Some applications are built using a 3-tier architecture and have interdependencies.

After failover, the VM's static IP address is retained, but DNS configuration is lost.

How should an administrator proceed to resolve this issue?

AConfigure Self-Service Restore.

BCreate custom in-guest scripts to preserve the statically assigned DNS IP addresses.

CInstall Network Manager command-line tool (nncli) in the protected Windows VMs.

DConfigure a Protection Domain.

Suggested Answer: B

During failover in Nutanix Disaster Recovery, VMs retain their static IPs but may lose DNS settings if the network configuration at the DR site is different from the primary site.

Option B (Create custom in-guest scripts) is correct:

Custom scripts allow Windows or Linux VMs to restore DNS settings automatically after failover.

These scripts can be executed using post-failover automation in Nutanix DR policies.

Option A (Self-Service Restore) is incorrect:

Self-Service Restore is used for end-user recovery of deleted files, not for network settings.

Option C (nncli tool) is incorrect:

The nncli tool is used for network troubleshooting, but it does not automatically restore DNS settings.

Option D (Configure a Protection Domain) is incorrect:

Protection Domains define replication policies, but they do not fix DNS settings after failover.

C is unnecessary, we don't need another tool for this.

I disagree, A might be more effective for quick restores.

D could help with overall protection, but not just DNS.

Madonna 10 months ago

Wait, I thought static IPs meant DNS wouldn't be an issue?

Adelaide 11 months ago

B seems like the best option to keep DNS intact.

I vaguely remember something about using network tools in VMs, but I’m not confident if nncli is the right approach for this DNS problem.

Ria 11 months ago

I feel like configuring a Protection Domain was more about backup schedules rather than DNS issues. I’m leaning towards the in-guest scripts option.

I think we practiced a similar question where we had to preserve settings during a failover. Creating custom scripts sounds familiar, but I can't recall the details.

Harrison 11 months ago

I remember discussing the importance of DNS in our DR plans, but I'm not sure which option directly addresses the DNS loss after failover.

Emile 12 months ago

I've got this! The question is asking us to resolve the DNS configuration issue after failover, so the answer has to be option B. Creating custom scripts to preserve the static DNS IP addresses is the way to go.

Katie 12 months ago

Okay, let's think this through step-by-step. Since the VMs retain their static IP addresses, we need to find a way to preserve the DNS configuration. Creating custom in-guest scripts sounds like the best approach to me.

Hmm, I'm a little confused about the DNS issue. I'll need to review the Nutanix DR documentation to make sure I understand the implications and how to properly address it.

This seems like a tricky question, but I think I can figure it out. The key is understanding how Nutanix DR handles DNS configuration after failover.

D) Configuring a Protection Domain seems like a logical choice. It should help the administrator manage the interdependencies between the 3-tier applications during the failover process.

Haha, I bet the exam writer was feeling cheeky when they included that 'Self-Service Restore' option. Surely that's not the right answer for this scenario!

C) Installing the Network Manager command-line tool (nncli) in the protected Windows VMs could be a convenient option. It should help automate the DNS configuration process post-failover.

B) Creating custom in-guest scripts to preserve the statically assigned DNS IP addresses seems like a solid solution. It's a proactive approach to ensure the DNS configuration is maintained after failover.

That's a valid point, Svetlana. Option D could indeed provide a more comprehensive solution for ensuring the integrity of the applications post-failover.

Svetlana 1 year ago

I disagree, I believe option D is the way to go. Configuring a Protection Domain will ensure that all necessary configurations are retained during failover.

Vilma 1 year ago

I think option B is the best choice. Preserving the statically assigned DNS IP addresses is crucial for maintaining connectivity after failover.
