Question:
A network administrator is implementing DHCPv6 for the company. The administrator configures a router to send RA messages with M flag as 1 by using the interface command ipv6 nd managed-config-flag. What effect will this configuration have on the operation of the clients?​

• Clients must use the information that is contained in RA messages.
• Clients must use all configuration information that is provided by a DHCPv6 server.
• Clients must use the prefix and prefix length that are provided by a DHCPv6 server and generate a random interface ID.
• Clients must use the prefix and prefix length that are provided by RA messages and obtain additional information from a DHCPv6 server.

Explanation: Under stateful DHCPv6 configuration, which is indicated by setting M flag as 1 (through the interface command ipv6 nd managed-config-flag), the dynamic IPv6 address assignments are managed by the DHCPv6 server. Clients must obtain all configuration information from a DHCPv6 server.
