An administrator is creating a recovery plan between two availability zones.

When failing over a virtual machine between different physical locations or availability zones, it is common for the network topology at the recovery site to differ from the primary site. If a VM is recovered into a site where its original subnet is unavailable, it will lose connectivity.

To resolve this, Nutanix Recovery Plans include a " Network Mapping " section. The administrator must configure these mappings to explicitly define which production subnet at the source site corresponds to which valid subnet at the recovery site. During the failover process, the orchestrator uses this mapping to automatically re-configure the VM ' s virtual network interface (vNIC) to connect to the correct local VLAN or overlay network at the destination. While " matching subnet names " (Option D) can simplify management, it is not a requirement if the mapping is correctly defined. Synchronous replication (Option B) does not address the networking layer, as it is a storage-level feature. Network mapping is therefore the essential task for ensuring that workloads are not only recovered but also accessible following a failover.
