Which of the following is the IPv6 connection addressing service mechanism option?

• A. None, DHCP
• B. SLAAC, Static or LL-only
• C. DHCP
• D. Static only

Answer: (B)

IPv6 addressing for a connection can be provided in several ways: by SLAAC (Stateless Address Autoconfiguration), by static configuration, or by using only link-local addresses on a given link. SLAAC lets a device automatically build a global address from router-advertised prefixes, while link-local addresses are always created automatically for on-link communication, and static addresses are manually assigned. The option that lists these common mechanisms—SLAAC, static, or LL-only—best reflects the ways IPv6 addresses can be provisioned. Other choices are too narrow (dhcp-only or static-only) or omit SLAAC, so they don’t capture the full range of IPv6 addressing methods.
