which of the following IPv6 address assignment methods …

In which of the following IPv6 address assignment methods will the interface receive its IPv6 address from a process native to IPv6, and receive additional
parameters from DHCP?

A.
Stateless DHCPv6

B.
Stateful DHCPv6

C.
DHCPv6-PD

D.
Stateless autoconfiguration

Explanation:
Stateless DHCPv6 uses a combination of processes to assign a configuration to an IPv6 interface. It uses Stateless Address Autoconfiguration (SAAC), a process
native to IPv6, to assign an IPv6 address to the interface. It uses DHCPv6 to assign other parameters, such as the DNS server and NTP server.
In stateful DHCPv6, the interface will receive the IPv6 address and all other parameters from the DHCP server.
In DHCPv6 Prefix Designation (DHCPv6-PD), the device is assigned a set of IPv6 “subnets.” This assignment will consist of a set of IPv6 addresses in the same
subnet (such as the address 2001:db8::/60) that the device can dynamically allocate to its interfaces.
