An administrator wants to configure hosts to automatically assign IPv6 addresses to themselves through the use of router advertisement messages, but also to obtain the DNS server address from a DHCPv6 server. Which address assignment method should be configured?

• RA and EUI-64
• SLAAC
• Stateful DHCPv6
• Stateless DHCPv6

Explanation: Stateless DHCPv6 allows clients to use ICMPv6 router advertisement (RA) messages to automatically assign IPv6 addresses to themselves but then allows these clients to contact a DHCPv6 server to obtain additional information such as the domain name and address of DNS servers. SLAAC does not allow the client to obtain additional information through DHCPv6, and stateful DHCPv6 requires that the client receive its interface address directly from a DHCPv6 server. RA messages, when combined with an EUI-64 interface identifier, are used to automatically create an interface IPv6 address and are part of both SLAAC and stateless DHCPv6.
