An administrator is using IPv4 on all servers. If a new technician installs only IPv6 on a workstation, which of the following servers will the workstation be able to access?

The DHCP server is IPv4-only; the IPv6-only workstation would need DHCPv6 or SLAAC for address assignment and cannot communicate with a legacy IPv4 DHCP server.

The domain controller is running IPv4 services; an IPv6-only host cannot establish a connection to it without dual-stack or translation support.

IPv4 and IPv6 use entirely different addressing schemes and packet formats with no built-in backward compatibility. Because all servers in the environment are configured with IPv4 only, and the workstation has only IPv6, there is no common protocol layer for communication. Without a translation mechanism such as NAT64/DNS64 or dual-stack configuration, the workstation cannot reach any of the IPv4-only servers.

The DNS server is IPv4-only; even though DNS is a higher-layer protocol, the underlying transport must match and an IPv6-only client cannot reach an IPv4-only DNS server.
