Description

1. The shortest compressed format of the IPv6 address 2001:0DB8:0000:1470:0000:0000:0000:0200 is .... --> 2001:DB8:0:1470::200 2. Which type of IPv6 address is not routable and use only for communication on a single subnet? --> link-local address 3. What is the prefix length notation for the subnet mask 255.255.255.224? --> /27 4. The 8-digit binary of the last octet of the IPv4 address 172.17.10.7 is ... ---> 00000111 5. Match the description to the IPv6 addressing component ○ This part of address is used by an organisation to identify subnets --> subnet ID ○ This network portion of the address is assigned by the provider --> global routing prefix ○ This part of the address is the equivalent to the host portion of an IPv4 address --> interface ID 6. A user who is unable to connect to the file server contacts the help desk. The helpdesk technician asks the user to ping the IP address of the default gateway that is configured on the workstation. What is the purpose of the ping command? --> to test that the host has the capability reach hosts on other networks 7. In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to host? --> SLAAC 8. The last host address on the 10.15.25.0/24 is ... ---> 10.15.25.254 9. The network portion of the address 172.16.30.5/16 is ... ---> 171.16 10. Which two types of devices are typically assigned static IP addresses? --> webservers --> printers 11. Match each description with an appropriate IP address? ○ A link-local address --> 169.254.1.5 ○ A public address --> 198.133.219.2

○ An experimental address --> 240.2.6.255 ○ A loopback address --> 127.0.0.1 12. An IPv6 enable 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 13. Which network migration techniques encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructure --> tunnelling 14. Match the IPv6 address with the IPv6 address type ○ 2001:DAB8::BAF:3F57:FE94 --> global unicast ○ FF02::1 --> all node multicast ○ ::1 --> loopback ○ FFO2::1:FFAE:F85F --> solicited note multicast 15. What field content is used by ICMPv6 to determine that a packet has expired? --> Hop limit field 16. What subnet mask is represented by the slash notation /20? --> 255.255.240.0 17. What is decimal equivalent of the hex number 0x3F? --> 63 18. What does the IP address 172.17.4.250/24 represent? --> host address 19. What is indicated by a successful ping to the ::1 IPv6 address? --> IP is properly installed on the host 20. What is the binary equivalent of the decimal number 232? --> 11101000 21. What type of address is automatically assigned to an interface when IPv6 is enabled on that interface? --> link-local 22. How many bits are in an IPv4 address? --> 32 23. Which protocol supports SLAAC for dynamic assignment of IPv6 addresses to a host? --> ICMPv6

24. What is the decimal equivalent of the binary number 10010101? --> 149 25. Which two things can be determined by using the ping command? --> 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 resource 26. What is the purpose of the subnet mask in conjunction with an IP address? --> to determine the subnet to which the host belongs 27. Which three IP addresses are private? --> 192.168.5.5 --> 172.16.4.4 --> 10.1.1.1 28. Which of these addresses is the shortest abbreviation for the ip address 3FFE:1044:0000:0000:00AB:0000:0000:0057 --> 3FFE:1044:0:0:AB::57 29. A message is sent to all hosts on a remote network. Which type of message is it? --> directed broadcast 30. Which two parts are components of an IPv4 address? --> network portion --> host portion 31. Which 2 IPv4 to IPv6 transition technique manage the interconnection of IPv6 domains? --> dual stack --> tunnelling 32. What are two types of IPv6 unicast address? --> loopback --> link-local 33. What are three characteristics of multicast transmission? --> the range of 224.0.0.0 to 224.0.0.255 is reserved to reach multicast groups on a local network --> a single packet can be sent to a group of hosts --> multicast transmission can be used by routers to exchange routing information 34. What are three parts of an IPv6 global unicast address?

--> an interface ID that is used to identify the local host on the network --> 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 35. Match each description with an appropriate IP address ○ 64.102.90.23 --> ○ 169.254.1.5 --> a link-local address ○ 192.2.0.123 --> a TEST-NET address ○ 240.2.6.255 --> an experimental address ○ 172.19.20.5 --> a private address ○ 127.0.0.1 --> a loppback address 36. A user is executing a tracert to a remote device. At what point would a router, which is in the path to the destination device, stop forwarding the packet? --> when the value in the TTL field reaches zero 37. What is the purpose of ICMP messages? --> to provide feedback of IP packet transmission...
