How does an IPv6 client ensure that it has a unique address after it configures its IPv6 address using the SLAAC allocation method?

• It sends an ICMPv6 Neighbor Solicitation message with the IPv6 address as the target IPv6 address.

• It contacts the DHCPv6 server via a special formed ICMPv6 message.

• It checks with the IPv6 address database that is hosted by the SLAAC server.

• It sends an ARP message with the IPv6 address as the destination IPv6 address.

Which method would an IPv6-enabled host using SLAAC employ to learn the address of the default gateway?

• router advertisements that are received from the link router.

• advertise messages that are received from the DHCPv6 server.

• reply messages that are received from the DHCPv6 server.

• neighbor advertisements that are received from the link neighbors.

What two methods can be used to generate an interface ID by an IPv6 host that is using SLAAC? (Choose two.)

• EUI-64

• ARP

• DAD

• stateful DHCPv6

• random generation

A client is using SLAAC to obtain an IPv6 address for its interface. After an address has been generated and applied to the interface, what must the client do before it can begin to use this IPv6 address?

• It must send a DHCPv6 REQUEST message to the DHCPv6 server to request permission to use this address.

• It must send a ICMPv6 Router Solicitation message to determine what default gateway it should use.

• It must send a DHCPv6 INFORMATION-REQUEST message to request the address of the DNS server.

• It must send a ICMPv6 Neighbor Solicitation message to ensure that the address is not already in use on the network.

Which command should be configured on a router interface to set the router as a stateful DHCPv6 client?

• ipv6 enable

• ipv6 address dhcp

• ipv6 address autoconfigure

• ipv6 dhcp server stateful

What message informs IPv6 enabled interfaces to use stateful DHCPv6 for obtaining an IPv6 address?

• the ICMPv6 Router Solicitation

• the ICMPv6 Router Advertisement

• the DHCPv6 Reply message

• the DHCPv6 Advertise message

Which destination IP address is used when an IPv6 host sends a DHCPv6 SOLICIT message to locate a DHCPv6 server?

• FF02::2

• FE80::1

• FF02::1

• FF02::1:2

In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?

• ARP

• SLAAC

• EUI-64

• ICMPv6

A company implements the stateless DHCPv6 method for configuring IPv6 addresses on employee workstations. After a workstation receives messages from multiple DHCPv6 servers to indicate their availability for DHCPv6 service, which message does it send to a server for configuration information?

• DHCPv6 SOLICIT

• DHCPv6 ADVERTISE

• DHCPv6 INFORMATION-REQUEST

• DHCPv6 REQUEST

What process is used in ICMPv6 for a host to verify that an IPv6 address is unique before configuring it on an interface?

• ARP

• EUI-64

• DAD

• SLAAC
