Cisco 2, Module 8

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

• ARP

• DAD

• stateful DHCPv6

• random generation

• EUI-64

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

• FE80 : : 1

• FF02 : : 1 : 2

• FF02 : : 1

• FF02 : : 2

What are two characteristics of the SLAAC method for IPv6 address configuration? (Choose two.)

• Router solicitation messages are sent by the router to offer IPv6 addressing to clients.

• The default gateway of an IPv6 client on a LAN will be the link-local address of the router interface attached to the LAN.

• IPv6 addressing is dynamically assigned to clients through the use of ICMPv6.

• This stateful method of acquiring an IPv6 address requires at least one DHCPv6 server.

• Clients send router advertisement messages to routers to request IPv6 addressing.

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

• DAD

• SLAAC

• EUI-64

• ARP

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 INFORMATION-REQUEST message to request the address of the DNS server.

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

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

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

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?

• neighbor advertisements that are received from link neighbors

• 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

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 INFORMATION-REQUEST

• DHCPv6 SOLICIT

• DHCPv6 REQUEST

• DHCPv6 ADVERTISE

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

• the DHCPv6 Advertise message

• the ICMPv6 Router Solicitation

• the ICMPv6 Router Advertisement

• the DHCPv6 Reply message

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

• SLAAC

• ICMPv6

• ARP

• EUI-64
