Match each description with an appropriate IP address. (Not all options are used.)

a link local address - 169.254.1.5 a TEST-NET address - 192.0.2.123 an experimental address 240.2.6.255 a loopback address - 127.0.0.1

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 devices on the local link​ or network

A host is transmitting a broadcast. Which host or hosts will receive it?

all hosts in the same subnet

Three methods allow IPv6 and IPv4 to co-exist. Match each method with its description. (Not all options are used.)

dual stack - ipv4 packets and the ipv6 packets coexist in the same network. tunneling - The ipv6 packet is transported inside an IPv4 packet. translation - ipv6 packets are converted into ipv4 packets, and vice versa.

Match each IPv4 address to the appropriate address category. (Not all options are used.)

host address 1 - 192.168.100.161/25 host address 2 - 203.0.113.100/24 network address 1 - 10.10.10.128/25 network address 2 - 172.110.12.64/28 broadcast address 1 - 192.168.1.191/26 broadcast address 2 - 10.0.0.159/27

What type of IPv6 address is FE80::1?

link-local

A user issues a ping fe80:65ab:dcc1::100 command and receives a response that includes a code of 4 . What does this code represent?

port unreachable

An administrator wants to create four subnetworks from the network address 192.168.1.0/24. What is the network address and subnet mask of the second useable subnet?

subnetwork 192.168.1.64 subnet mask 255.255.255.192

What is the purpose of ICMP messages?

to provide feedback of IP packet transmissions

A user executes a traceroute over IPv6. At what point would a router in the path to the destination device drop the packet?

Match the subnetwork to a host address that would be included within the subnetwork. (Not all options are used.)

192.168.1.68 - 192.168.1.64/27 192.168.1.48 - 192.168.1.32/27 192.168.1.121 - 192.168.1.96/27

Which address is a valid IPv6 link-local unicast address?

FE80::1:4545:6578:ABC1

Refer to the exhibit. A company is deploying an IPv6 addressing scheme for its network. The company design document indicates that the subnet portion of the IPv6 addresses is used for the new hierarchical network design, with the s ite subsection to represent multiple geographical sites of the company, the s ub-site section to represent multiple campuses at each site, and the subnet section to indicate each network segment separated by routers. With such a scheme, what is the maximum number ofsubnets achieved per sub-site ?

16

Which type of IPv6 address refers to any unicast address that is assigned to multiple hosts?

anycast

A high school in New York (school A) is using videoconferencing technology to establish student interactions with another high school (school B) in Russia. The videoconferencing is conducted between two end devices through the Internet. The network administrator of school A configures the end device with the IP address 209.165.201.10. The administrator sends a request for the IP address for the end device in school B and the response is 192.168.25.10. Neither school is using a VPN. The administrator knows immediately that this IP will not work. Why?

This is a private IP address.
