Question 164

Which of the following packets is sent by a DHCPv6 client before it sends a request packet to the DHCPv6 server?

    Correct Answer: B

    In the DHCPv6 process, a client initially sends a Router Solicitation (RS) message to solicit information from routers on the network. The router responds with a Router Advertisement (RA) message, which can include information about DHCPv6 servers. Based on the options provided, the correct packet sent by a DHCPv6 client before sending a request packet to the server is the Router Solicitation (RS).

BD I think that the correct answer there should be SOLICIT Packet, based on the For-way Negotiation (SARR). Before it will send a REQUEST packet to a DHCPv6 server, it should've sent a SOLICIT packet. But NS and RS could also be seem correct from a IPv6 node(client) context, prior to the allocation of addresses, it should be clearly understood that an IPv6 node(client) is required to generate a link-local address and be successfullly evaluated by the Duplicate Address Detection (DAD) process (NS & NA). Following this, a link router discovery process is involved, for which the IPv6 client node broadcast a Router Solicitation(RS) message, and the link router responds with a Router Advertisment(RA) message after receiving the RS message.
