Pavel should create a public DNS zone and add the record set for the VM's FQDN because this is essential for allowing external clients to resolve the domain name to an IP address. In Azure, when a VM is meant to be internet-facing, it typically requires a public IP address that is tied to its Fully Qualified Domain Name (FQDN). By creating a public DNS zone, Pavel ensures that the domain name is properly managed and can be resolved by clients over the Internet.

This approach allows for the necessary mapping between the FQDN and the public IP address of the VM. Furthermore, managing this in a public DNS zone means it can be more efficiently handled and accessed by external clients, leading to better connectivity and availability.

The other options, while they may touch on aspects of DNS resolution and connectivity, do not directly address the requirement of setting up a public DNS zone to facilitate the resolution of the FQDN for an internet-facing VM in Azure.
