Correct Answer: Box 1: Private Box 2: Private You can only link VNETs to private DNS zones only and accordingly auto register a VNET only to a private DNS zones. Private DNS zones can be linked with VNETs (not public ones). And VM can auto-register to any private DNS zone linked with the Vnet and with auto-registration option set. To resolve the records of a private DNS zone from your virtual network, you must link the virtual network with the zone. Linked virtual networks have full access and can resolve all DNS records published in the private zone.

DNS zones that can link to VNET1: Azure private DNS zones can be linked to virtual networks, enabling resources in the virtual network to resolve DNS records within that zone. Therefore, only private zones can be linked to virtual networks. Answer: The private zones only DNS zones to which VM1 can automatically register: VM1 can automatically register its hostname in private DNS zones to which the virtual network (VNET1) is linked. Public DNS zones do not support automatic registration of virtual machine hostnames. Answer: The private zones only

bad question or options provided "A specific virtual network can be linked to only one private DNS zone when automatic VM DNS registration is enabled. You can, however, link multiple virtual networks to a single DNS zone." so assuming that autoregistration is on - we can link it to just 1 private zone

I think it is not correcxt 1 = Private zones 2 = Adatum.com since it is set to the server , thus the nic that takes precedent over other dns settings. If the settings did not sauy adatum.com on the server lver, than it was both private dns

To resolve the records of a private DNS zone from your virtual network, you must link the virtual network with the zone. Linked virtual networks have full access and can resolve all DNS records published in the private zone.
