An administrator needs to extend an on-premises subnet to an NC2 cluster on Azure. Which set of options should the administrator configure to complete this task?

Extending an on-premises subnet to NC2 on Azure uses the Layer 2 VPN feature of Nutanix Flow Virtual Networking. This requires connecting an on-premises VLAN-backed subnet to a VPC overlay subnet in the cloud. The connection must support IPv4 unicast traffic and ARP for address resolution across the stretched L2 segment. Modern implementations also support IPv6. The on-premises component, the Nutanix VPN gateway appliance, is officially supported on AHV and ESXi hypervisors.

A. This is incorrect because the configuration must involve both on-premises VLAN subnets and cloud VPC subnets, not just VPC subnets.
C. This is too restrictive. The on-premises VPN gateway appliance is supported on both AHV and ESXi, not just AHV.
D. This is incorrect as it omits the mandatory support for IPv4 traffic. Additionally, Hyper-V is not a supported platform for the on-premises VPN gateway appliance.

1. Nutanix Flow Virtual Networking Guide v6.7, "Subnet Extension Using Layer 2 VPN > Prerequisites for Subnet Extension". This section explicitly lists the supported on-premises hypervisors as AHV and ESXi.

2. Nutanix Flow Virtual Networking Guide v6.7, "Subnet Extension Using Layer 2 VPN". The documentation details that the feature extends the L2 broadcast domain, which inherently requires handling ARP and supports both IPv4 and IPv6 unicast traffic.
