CCNA 2 Module 8 test
It must send an ICMPv6 Neighbor Solicitation message to ensure that the address is not already in use on the network.
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?
DHCPv6 INFORMATION-REQUEST
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?
The link-local address of the router interface that is attached to the network
A company uses the SLAAC method to configure IPv6 addresses for the employee workstations. Which address will a client use as its default gateway?
It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information
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 use the information that is contained in the RA message and contact a DHCPv6 server for additional information.
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 is required for sending ICMPv6 RA messages.
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?
Clients must use all configuration information that is provided by a DHCPv6 server.
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?
The client should automatically configure an IPv6 address and then contact a DHCPv6 server for more information.
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?
SLAAC and stateless DHCPv6
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?
R1(config)# ipv6 unicast-routing
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?
It sends an ICMPv6 Neighbor Solicitation message with the IPv6 address as the target IPv6 address.
How does an IPv6 client ensure that it has a unique address after it configures its IPv6 address using the SLAAC allocation method?
SLAAC
In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?
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.
What are two characteristics of the SLAAC method for IPv6 address configuration? (Choose two.)
The MAC address of an Ethernet interface
What is used in the EUI-64 process to create an IPv6 interface ID on an IPv6 enabled interface?
the ICMPv6 Router Advertisement
What message informs IPv6 enabled interfaces to use stateful DHCPv6 for obtaining an IPv6 address?
DAD
What process is used in ICMPv6 for a host to verify that an IPv6 address is unique before configuring it on an interface?
random generation EUI-64
What two methods can be used to generate an interface ID by an IPv6 host that is using SLAAC? (Choose two.)
The connecting router link-local address
When SLAAC is used, which address will a client use as its default gateway?
ipv6 address dhcp
Which command should be configured on a router interface to set the router as a stateful DHCPv6 client?
FF02::1:2
Which destination IP address is used when an IPv6 host sends a DHCPv6 SOLICIT message to locate a DHCPv6 server?
router advertisements that are received from the link router
Which method would an IPv6-enabled host using SLAAC employ to learn the address of the default gateway?
