Which two methods are used to assign IPv6 addresses to nodes?

• A. SLAAC and DHCPv6
• B. SLAAC only
• C. DHCPv6 only
• D. DHCP and SLAAC

Answer: (A)

IPv6 addresses can be assigned to hosts using two primary mechanisms: SLAAC and DHCPv6. SLAAC relies on router advertisements to share the network prefix, and each host automatically combines that prefix with an interface identifier to form its own address, without needing a dedicated address server. DHCPv6, on the other hand, uses a DHCPv6 server to assign addresses (and can also provide other configuration like DNS). In many networks you may see both mechanisms available, with SLAAC handling the address assignment in some cases and DHCPv6 providing addresss in others or supplying additional configuration. Hence, the two methods used to assign IPv6 addresses are SLAAC and DHCPv6.
