Which IPv6 address assignment methods are used? DHCP, Static and SLAAC.

• A. DHCP, SLAAC and DHCPv6
• B. DHCP, SLAAC and Static
• C. DHCP, SLAAC and DHCPv6
• D. DHCP, Static and SLAAC

Answer: (D)

IPv6 address assignment can be done in three ways: SLAAC, DHCPv6, and static/manual configuration. SLAAC uses router advertisements to learn the network prefix and then the device combines that prefix with an interface identifier to form its address, with no server handing out the address. DHCPv6 involves a server assigning addresses (and often providing other configuration) in a stateful manner. Static addressing is when an administrator assigns a fixed address to a device. Because IPv6 supports all three methods, the option listing DHCP, Static and SLAAC correctly covers the complete set. In many contexts, DHCP is used to refer to DHCPv6 for IPv6 addressing, so this choice aligns with the typical understanding.
