Look up Azure pass or you can get a free account with 200USD credit which you can convert to PAYG after 30 days.Free account has some restrictions but should be fine for labs.

Selected Answer: D
D for Sure.. Reverse DNS is supported in all ARM based virtual networks. You can issue reverse DNS queries (PTR queries) to map IP addresses of virtual machines to FQDNs of virtual machines. All PTR queries for IP addresses of virtual machines will return FQDNs of form [vmname].internal.cloudapp.net Forward lookup on FQDNs of form [vmname].internal.cloudapp.net will resolve to IP address assigned to the virtual machine. If the virtual network is linked to an Azure DNS private zones as a registration virtual network, the reverse DNS queries will return two records. One record will be of the form [vmname].[privatednszonename] and the other will be of the form [vmname].internal.cloudapp.net
