1. How does an IPv6 client ensure that it has a unique address after it configures its IPv6 address using the SLAAC allocation method?
- 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.
- It sends an ICMPv6 Neighbor Solicitation message with the IPv6 address as the target IPv6 address.
2. Which method would an IPv6-enabled host using SLAAC employ to learn the address of the default gateway?
- neighbor advertisements that are eceived from link neighbors
- router advertisements that are received from the link router
- reply messages that are received from the DHCPv6 server

4. 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 a DHCPv6 REQUEST message to the DHCPv6 server to request permission to use this address.
- It must send an ICMPv6 Router Solicitation message to determine what default gateway it should use.
- It must send an ICMPv6 Neighbor Solicitation message to ensure that the address is not already in use on the network.
5. Which command should be configured on a router interface to set the router as a stateful DHCPv6 client?

8. In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?
- SLAAC
- EUI-64
- ICMPv6
- ARP
9. 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 REQUEST
- DHCPv6 INFORMATION-REQUEST
- DHCPv6 ADVERTISE
- DHCPv6 SOLICIT
10. What process is used in ICMPv6 for a host to verify that an IPv6 address is unique before configuring it on an interface?
- EUI-64
- SLAAC
- ARP
- DAD
11. 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.
- 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.
- IPv6 addressing is dynamically assigned to clients through the use of ICMPv6.
12. After booting, a client receives an ICMPv6 RA message with the M flag set to 0 and the O flag set to 1. What does this indicate?
- The client should request an IPv6 address directly from a DHCPv6 server.
- The client should automatically configure an IPv6 address and then contact a DHCPv6 server for more information.
- The client should automatically configure an IPv6 address without contacting a DHCPv6 server.
- The client should be statically configured with an IPv6 address because the local router does not support autoconfiguration.
13. A network administrator is entering the command ipv6 unicast-routing to start configuring DHCPv6 operation on a router. Which statement describes the function of this command?
- It is required for enabling DNS service in DHCPv6 configurations.
- It is required for sending ICMPv6 RA messages.
- It is required to configure stateless DHCPv6 server on the router.
- It is required to configure stateful DHCPv6 server on the router.
14. A company uses the SLAAC method to configure IPv6 addresses for the employee workstations. Which address will a client use as its default gateway?
- The all-routers multicast address
- The global unicast address of the router interface that is attached to the network
- The link-local address of the router interface that is attached to the network
- The unique local address of the router interface that is attached to the network
15. A network administrator configures a router to send RA messages with the A flag and O flag set to 1. The M flag is set to 0. Which statement describes the effect of this configuration when a PC tries to configure its IPv6 address?
- It should contact a DHCPv6 server for all the information that it needs.
- It should contact a DHCPv6 server for the prefix, the prefix-length information, and an interface ID that is both random and unique.
- It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information.
- It should use the information that is contained in the RA message exclusively.
16. An administrator wants to configure hosts to automatically assign IPv6 addresses to themselves by the use of Router Advertisement messages, but also to obtain the DNS server address from a DHCPv6 server. Which address assignment method should be configured?
- RA and EUI-64
- SLAAC
- Stateful DHCPv6
- SLAAC and stateless DHCPv6
17. What is used in the EUI-64 process to create an IPv6 interface ID on an IPv6 enabled interface?
- A randomly generated 64-bit hexadecimal address
- An IPv4 address that is configured on the interface
- An IPv6 address that is provided by a DHCPv6 server
- The MAC address of an Ethernet interface
18. A network administrator is implementing DHCPv6 for the company. The administrator configures a router to send RA messages with M flag as 1 by using the ipv6 nd managed-config-flag interface command, and the A flag is set to 0 using the ipv6 nd prefix default no-autoconfig command. What effect will this configuration have on the operation of the clients?
- Clients must use all configuration information that is provided by a DHCPv6 server.
- Clients must use the information that is contained in RA messages.
- Clients must use the prefix and prefix length that are provided by a DHCPv6 server and generate a random interface ID.
- Clients must use the prefix and prefix length that are provided by RA messages and obtain additional information from a DHCPv6 server.
19. An organization requires that LAN clients generate their IPv6 configuration using SLAAC. You have configured the IPv6 GUA on the router LAN interface and verified that the interface is UP. However, hosts are not generating an IPv6 GUA. Which other command should be configured to enable SLAAC?
- R1(config)# ipv6 dhcp pool pool-name
- R1(config)# ipv6 unicast-routing
- R1(config-if)# ipv6 enable
- R1(config-if)# ipv6 nd other-config-flag
20. A network administrator configures a router to send RA messages with M flag as 0 and O flag as 1. Which statement describes the effect of this configuration when a PC tries to configure its IPv6 address?
- It should contact a DHCPv6 server for all the information that it needs.
- It should contact a DHCPv6 server for the prefix, the prefix-length information, and an interface ID that is both random and unique.
- It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information.
- It should use the information that is contained in the RA message exclusively.
21. When SLAAC is used, which address will a client use as its default gateway?
