An IPv6 address on a host moves from the preferred state to the deprecated state when which of the following events occurs? - Answer-The preferred lifetime timer expires and the valid lifetime timer is valid. Which of the following represent a valid DHCP software component? (Choose all that apply.) - Answer-• DHCP server • DHCP client Which of the following represent a valid enhancement found in DHCPv6 or a valid related enhancement that is part of the basic IPv6 environment? (Choose all that apply.) - Answer-• DHCPv6 servers and routers can be configured to send advertisements in authenticated form. • IPv6 interfaces support multiple addresses in DHCPv6. • DHCPv6 can be set up to dynamically update DNS records. • IPv6 nodes must listen for address updates to support automatic renumbering. Which flag is required to be set to "on" in an RA for a host to send a request to a DHCPv6 server? - Answer-• M flag What type of packet does a DHCP server send to a DHCP client in reply to a Discover packet? - Answer-• Offer packet When a DHCP server is not available on the same network segment as a DHCP client, which technique permits the DHCP client's initial DHCP broadcast requests to be serviced? - Answer-• Configuring internal routers to forward DHCP requests from network segments or broadcast domains where DHCP clients reside to segments where DHCP servers reside. What kind of DHCP packet does the server send to the client to denote completion of the DHCP Discovery process? - Answer-• DHCP Acknowledgment (ACK) packet How does a DHCP relay forward the DHCP server's reply to a client's initial address request? - Answer-• It uses the MAC layer address for the requester.When a node creates a link-local address, which of the following methods for creating an IID can be appended to the well-known link-local prefix fe80::/64? - Answer-• the 64-bit modified EUI-64 address • a 64-bit randomly generated address How does a DHCP client accept an offer from a DHCP server? - Answer-• by issuing a DHCP Request packet Which of the following UDP port numbers are associated with DHCPv6? - Answer-• 546 and 547 Which of the following best explain why a DHCP Discover packet is broadcast to the local network segment? (Choose all that apply.) - Answer-• because the client has no IP address and cannot send a unicast • because the address of a DHCP server is not known Which of the following types of machines is best suited for dynamic IP address assignment? (Hint: Some kinds of machines require persistent IP addresses to remain easy to find on the Internet; others do not.) - Answer-• Clients Which activities occur during the process of IPv6 autoconfiguration? (Choose all that apply.) - Answer-• 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. Which of the following UDP port numbers are associated with DHCP? - Answer-• 67 and 68 Which issue explains why DHCP was not traditionally used to manage server and router addresses? - Answer-• Servers and routers often depend on DNS, which must be manually updated when addresses change. On a Windows 10 host, if the host does not receive an RA in response to its RS, what is its next step in the IPv6 address autoconfiguration process? - Answer-• Send a DHCPv6 Solicit message.
