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?
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.
