A network administrator configures a router to send RA messages with the A flag and O flag set to 1. The M flag is set to 0. Which statement describes the effect of this configuration when a PC tries to configure its IPv6 address?
- It should contact a DHCPv6 server for all the information that it needs.
- It should contact a DHCPv6 server for the prefix, the prefix-length information, and an interface ID that is both random and unique.
- It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information.
- It should use the information that is contained in the RA message exclusively.
Explanation: ICMPv6 RA messages contain flags to indicate whether a workstation should use SLAAC, a DHCPv6 server, or a combination to configure its IPv6 address. The A flag determines whether to use SLAAC. The O flag indicates whether to use a stateless DHCPv6 server. The M flag indicates whether to use stateful DHCPv6. The M and O flags are independent of SLAAC.
