NCP-MCI-6.10 · Question #125
An administrator has deployed two Nutanix clusters and is now establishing synchronous replication between them. However, the replication is failing immediately. Which two responses show the reason…
The correct answer is A. If the primary and the recovery clusters are in different subnets, open the ports manually for D. Use the command modify_firewall to open the ports on eth0 interface. Synchronous replication between Nutanix clusters in different subnets requires manual firewall port configuration, and the modify_firewall command must target the eth0 interface.
Question
An administrator has deployed two Nutanix clusters and is now establishing synchronous replication between them. However, the replication is failing immediately. Which two responses show the reason and corrective action an administrator can take to resolve the issue? (Choose two.)
Options
- AIf the primary and the recovery clusters are in different subnets, open the ports manually for
- BIf the primary and the recovery clusters are on the same subnet, open the ports manually for
- CUse the command modify_firewall to open the ports on eth1 interface.
- DUse the command modify_firewall to open the ports on eth0 interface

Why each option
Synchronous replication between Nutanix clusters in different subnets requires manual firewall port configuration, and the modify_firewall command must target the eth0 interface.
When the primary and recovery clusters reside in different subnets, the firewall does not automatically permit replication traffic, so an administrator must manually open the required ports to allow communication between the two clusters.
Clusters on the same subnet do not require manual port opening because firewall rules for local subnet traffic are handled automatically by Nutanix.
eth1 is not the interface used for replication traffic; using it would not open the correct ports, and the command must target eth0 instead.
The modify_firewall command must be run targeting eth0, which is the primary data/CVM network interface used for replication and cluster communication; eth1 is not the correct interface for this purpose.
Concept tested: Nutanix synchronous replication firewall port configuration
