Answer F
Wrong answer is given. 🙁
The correct one is B (only). Here is why:
“Name Protection is based on the DHCID support to the DHCP server, and support for the new DHCID RR (Resource Record) to Microsoft DNS. In addition, support for DUID will be added to the IPv4 registration on the DHCP client.
Note this feature prevents name squatting due to non-Windows OS machines, for example servers with Mac OS, various Linux, and other variants of non Windows operating systems. In case of Windows OS machines it would not be an issue, as administrators can leverage upon Active Directory ACL functionality to limit access rights to a name to a particular user/machine and thus prevent name squatting. ”
