When performing a failover from an on-premises VM or server to an Azure VM, what is true about the network interfaces created?

When performing a failover from an on-premises VM or server to an Azure VM, the correct understanding revolves around the behavior of network interfaces created by Azure Site Recovery. In this scenario, Azure Site Recovery is designed to replicate the configuration of the on-premises environment within Azure to ensure a seamless transition.

The statement regarding the creation of network interfaces reflects that Azure Site Recovery creates the same number of network interfaces on the Azure VM as are present on the on-premises server. This design is crucial because it helps maintain the network architecture and ensures that the Azure VM can integrate effectively into the virtual network, retaining the same connectivity as the original server. By matching the network interface count, Azure can facilitate an easier configuration process during the failover, allowing for consistent IP addressing and network settings needed for applications and services to function without disruption.

Other statements that suggest variations in interface creation may not align with the replicative nature of Azure Site Recovery, which aims to mimic the on-premises setup as closely as possible for optimal performance upon failover.
