IPv6 interfaces support multiple addresses in DHCPv6
IPv6 nodes must listen for address updates to support automatic renumbering
Nodes under IPv6 can obtain locally functioning addresses in DHCPv6
DHCPv6 servers and routers can be configured to send advertisements in authenticated form
DHCPv 6 can be set up to dynamically update DNS records
A. None do. A DHCP server must be available on any network segment or broadcast domain where a DHCP client resides.
B. Installing a DHCP relay agent on any network segment or broadcast domain where a DNS server is not directly attached
c. Installing a remote DHCP agent on any network segment or broadcast domain where a DNS server is not directly attached.
D. Configuring internal routers to forward DHCP requests from network segments or broadcast domains where DHCP clients reside to segments where DHCP servers reside.
E. Configuring internal routers to forward DHCP requests from network segments or broadcast domains where DHCP servers reside to segments where DHCP clients reside.
It uses a temporary IP address created for the requester
IT uses the IP address offered to the requester
IT uses the MAC layer address for the requester
It broadcasts a reply, for which the requester listens
64-bit randomly generated address
The 64-bit MAC address
The 64-bit modified EUI-64 address
a 64-bit CGS
Routers and servers require static IP address assignments
DCHP is a client only solution
DHCP may only be updated manually, so it's not suitable for servers or routers
Servers and routers often depend on DNS which must be manually updated when addresses change
None of the above
The node checks its calculated link-local address with a Neighbor Solicitation to make sure that address is not already in use.
The node makes an RS to obtain RAs from attached routers.
The node attempts to calculate a link-local address by prepending its EUI-64 IID with the well-known link-local prefix.
Once a DHCPv6 server is identified, it always provides all necessary information to complete the autoconfiguration process.
All of the above
