Which statement correctly reflects the interaction of DHCPv6 and SLAAC under certain router configurations?

• A. Both can be used together depending on router flags
• B. Only one of them can be used even if flags permit both
• C. SLAAC must be disabled
• D. DHCPv6 is the only method for address assignment

Answer: (A)

The idea being tested is how IPv6 autoconfiguration can mix SLAAC and DHCPv6 choices based on router advertisements. Routers send a prefix and two flags in their advertisements: the Managed flag and the Other configuration flag. The Managed flag tells hosts to use DHCPv6 for address assignment, while the Other flag tells hosts to use DHCPv6 to obtain additional configuration like DNS servers. But this doesn’t force a single method for everything. In many setups you can have the address itself come from SLAAC (using the advertised prefix) while still using DHCPv6 to provide other information. That means both methods can operate together, depending on how the router flags are set. This flexibility is exactly what option choices describe as the correct idea.
