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.

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

Just tested it in my Azure environment - no, it is not required to be in the same region, I can add VNets from different regions.

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

If you enable autoregistration on a virtual network link, the DNS records for the virtual machines on that virtual network are registered in the private zone. When autoregistration is enabled, Azure DNS also updates the zone records whenever a virtual machine is created, changes its' IP address, or is deleted.
