Messaging between an IPv6 router and an IPv6 device, including dynamic address allocation are as follows:
Router Solicitation (RS) message
Router Advertisement (RA) message
Neighbor Advertisement ( NA ) message.
Neighbor Solicitation ( NS ) message.
Ping can be used to test the internal configuration of IPv4 / IPv6 on the local host. To do this, ping the local loopback address of 127.0.0.1 for IPv4 (::1 for IPv6).
False
True
Traceroute provides round-trip time for each hop along the path and indicates if a hop fails to respond. An asterisk (*) is used to indicate a lost or unreplied packet.
False
True
A company uses the method SLAAC to configure IPv6 addresses for the workstations of the employees. A network administrator configured the IPv6 address on the LAN interface of the router. The interface status is up/up. However, the workstations on the LAN segment did not obtain the correct prefix and prefix length. What else should be configured on the router that is attached to the LAN segment for the workstations to obtain the information?
R1(config-if)# ipv6 enable
R1(config)# ipv6 unicast-routing
R1(config-if)# ipv6 nd other-config-flag
R1(config)# ipv6 dhcp pool < name of the pool >
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 use the information that is contained in the RA message exclusively.
It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information.
It should contact a DHCPv6 server for the prefix, the prefix-length information, and an interface ID that is both random and unique.
Refer to the exhibit. A network administrator is implementing the stateless DHCPv6 operation for the company. Clients are configuring IPv6 addresses as expected. However, the clients are not getting the DNS server address and the domain name information configured in the DHCP pool. What could be the cause of the problem?
The GigabitEthernet interface is not activated.
The router is configured for SLAAC operation.
The DNS server address is not on the same network as the clients are on.
The clients cannot communicate with the DHCPv6 server, evidenced by the number of active clients being 0.
Refer to the exhibit. A network administrator is configuring a router as a DHCPv6 server. The administrator issues a show ipv6 dhcp pool command to verify the configuration. Which statement explains the reason that the number of active clients is 0?
The default gateway address is not provided in the pool.
No clients have communicated with the DHCPv6 server yet.
The IPv6 DHCP pool configuration has no IPv6 address range specified.
The state is not maintained by the DHCPv6 server under stateless DHCPv6 operation.
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 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
the global unicast address of the router interface that is attached to the network
Refer to the exhibit. A network administrator is configuring a router for DHCPv6 operation. Which conclusion can be drawn based on the commands?
The DHCPv6 server name is ACAD_CLASS.
The router is configured for stateless DHCPv6 operation.
Clients would configure the interface IDs above 0010.
The router is configured for stateful DHCPv6 operation, but the DHCP pool configuration is incomplete.
Refer to the exhibit. Based on the output that is shown, what kind of IPv6 addressing is being configured?
SLAAC
Stateful DHCPv6
stateless DHCPv6
static link-local
