Router# configure terminalRouter(config)# interface fastethernet 0/0Router(config-if)# ip address 192.168.1.254 255.255.255.0Router(config-if)# no shutdownRouter(config-if)# exitRouter(config)# ipv6 unicast-routing Router# configure terminalRouter(config)# interface fastethernet 0/0Router(config-if)# ipv6 address 2001:db8:bced:1::9/64Router(config-if)# no shutdownRouter(config-if)# exitRouter(config)# ipv6 unicast-routing Router# configure terminalRouter(config)# interface fastethernet 0/0Router(config-if)# ipv6 address 2001:db8:bced:1::9/64Router(config-if)# no shutdownRouter# configure terminalRouter(config)# interface fastethernet 0/0Router(config-if)# ip address 2001:db8:bced:1::9/64Router(config-if)# ip address 192.168.1.254 255.255.255.0Router(config-if)# no shutdown Router# configure terminalRouter(config)# interface fastethernet 0/0

B) 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(config-if)# exit Router(config)# ipv6 unicast-routing

Which message is displayed on the web server? Correct configuration! IPv6 address configured! You did it right! Successful configuration!

Correct configuration!

1.What is indicated by a successful ping to the ::1 IPv6 address? IP is properly installed on the host. The link-local address is correctly configured. The default gateway address is correctly configured. The host is cabled properly. All hosts on the local link are available.

IP is properly installed on the host.

5.Which two statements are correct about IPv4 and IPv6 addresses? (Choose two.) IPv4 addresses are 32 bits in length. IPv6 addresses are represented by hexadecimal numbers. IPv6 addresses are 32 bits in length. IPv4 addresses are 128 bits in length. IPv4 addresses are represented by hexadecimal numbers. IPv6 addresses are 64 bits in length.

IPv4 addresses are 32 bits in length. IPv6 addresses are represented by hexadecimal numbers.

14.What two statements describe characteristics of Layer 3 broadcasts? (Choose two.) Routers create broadcast domains A limited broadcast packet has a destination IP address of 255.255.255.255 There is a broadcast domain on each switch interface. A router will not forward any type of Layer 3 broadcast packet. Broadcasts are a threat and users must avoid using protocols that implement them. Some IPv6 protocols use broadcasts.

Routers create broadcast domains A limited broadcast packet has a destination IP address of 255.255.255.255

10.An IPv6 enabled device sends a data packet with the destination address of FF02::1. What is the target of this packet? all IPv6 enabled nodes on the local link all IPv6 configured routers across the network all IPv6 configured routers on the local link all IPv6 DHCP servers

all IPv6 enabled nodes on the local link

22.A message is sent to all hosts on a remote network. Which type of message is it? directed broadcast limited broadcast unicast multicast

direct broadcast

13.What are two types of IPv6 unicast addresses? (Choose two.) loopback link-local anycast multicast

loopback link-local

Which two parts are components of an IPv4 address? (Choose two.)

network portion host portion

2.Which two ICMP messages are used by both IPv4 and IPv6 protocols? (Choose two.) route redirection protocol unreachable router solicitation neighbor solicitation router advertisement

route redirection protocol unreachable

4.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? solicited-node multicast address global unicast address of the receiver all-node multicast address link-local address of the receiver

solicited-node multicast address

12.Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures? tunneling encapsulation translation dual-stack

tunneling

15.When will a router drop a traceroute packet? when the value in the TTL field reaches zero when the router receives an ICMP Time Exceeded message when the host responds with an ICMP Echo Reply message when the values of both the Echo Request and Echo Reply messages reach zero when the RTT value reaches zero

when the value in the TTL field reaches zero

7.Which two things can be determined by using the ping command? (Choose two.) whether or not the destination device is reachable through the network the average time it takes a packet to reach the destination and for the response to return to the source the average time it takes each router in the path between source and destination to respond the IP address of the router nearest the destination device the number of routers between the source and destination device

whether or not the destination device is reachable through the network the average time it takes a packet to reach the destination and for the response to return to the source
