• a global routing prefix that is used to identify the network portion of the address that has been provided by an ISP
• a subnet ID that is used to identify networks inside of the local enterprise site
• a global routing prefix that is used to identify the portion of the network address provided by a local administrator

  Router(config)# ipv6 unicast-routing
   
• Router# configure terminal
  Router(config)# interface fastethernet 0/0
  Router(config-if)# ipv6 address 2001:db8:bced:1::9/64
  Router(config-if)# no shutdown

• Router# configure terminal
  Router(config)# interface fastethernet 0/0
  Router(config-if)# ip address 2001:db8:bced:1::9/64Router(config-if)# ip address 192.168.1.254 255.255.255.0

14. Which two ICMP messages are used by both IPv4 and IPv6 protocols? (Choose two.)?

• router solicitation
• route redirection
• neighbor solicitation
• protocol unreachable
• router advertisement

15. When an IPv6 enabled host needs to discover the MAC address of an intended IPv6 destination, which destination address is used by the source host in the NS message?

• all-node multicast address
• solicited-node multicast address
• link-local address of the receiver
• global unicast address of the receiver

16. When will a router drop a traceroute packet?

• when the router receives an ICMP Time Exceeded message
• when the RTT value reaches zero
• when the host responds with an ICMP Echo Reply message
• when the value in the TTL field reaches zero
• when the values of both the Echo Request and Echo Reply messages reach zero

17. What is indicated by a successful ping to the ::1 IPv6 address?

• The host is cabled properly.
• The default gateway address is correctly configured.
• All hosts on the local link are available.
• The link-local address is correctly configured.
• IP is properly installed on the host.

18. Which two things can be determined by using the ping command? (Choose two.)

• the number of routers between the source and destination device
• the IP address of the router nearest the destination device
• the average time it takes a packet to reach the destination and for the response to return to the source
• whether or not the destination device is reachable through the network
