  1. How many bits are in an IPv4 address?

    • 32
    • 64
    • 128
    • 256
      Explanation:

      An IPv4 address is comprised of four octets of binary digits, each containing 8 $.25, resulting in a 32-bit accost.

  2. Which 2 parts are components of an IPv4 accost? (Choose ii.)

    • subnet portion
    • network portion
    • logical portion
    • host portion
    • physical portion
    • broadcast portion
      Explanation:

      An IPv4 address is divided into two parts: a network portion – to identify the specific network on which a host resides, and a host portion – to identify specific hosts on a network. A subnet mask is used to place the length of each portion.

  3. What does the IP address 172.17.4.250/24 stand for?

    • network address
    • multicast accost
    • host address
    • broadcast address
      Explanation:

      The /24 shows that the network accost is 172.17.4.0. The broadcast accost for this network would be 172.17.iv.255. Useable host addresses for this network are 172.17.4.ane through 172.17.four.254.

  4. What is the purpose of the subnet mask in conjunction with an IP address?

    • to uniquely place a host on a network
    • to identify whether the address is public or private
    • to determine the subnet to which the host belongs
    • to mask the IP address to outsiders
      Explanation:

      With the IPv4 address, a subnet mask is also necessary. A subnet mask is a special type of IPv4 address that coupled with the IP accost determines the subnet of which the device is a member. ​

  5. What subnet mask is represented by the slash notation /20?

    • 255.255.255.248
    • 255.255.224.0
    • 255.255.240.0
    • 255.255.255.0
    • 255.255.255.192
      Explanation:

      The slash notation /twenty represents a subnet mask with 20 1s. This would translate to: 11111111.11111111.11110000.0000, which in turn would catechumen into 255.255.240.0.

  6. A message is sent to all hosts on a remote network. Which blazon of message is it?

    • express broadcast
    • multicast
    • directed broadcast
    • unicast
      Caption:

      A directed broadcast is a message sent to all hosts on a specific network. It is useful for sending a broadcast to all hosts on a nonlocal network. A multicast message is a message sent to a selected grouping of hosts that are part of a subscribing multicast grouping. A limited broadcast is used for a communication that is limited to the hosts on the local network. A unicast bulletin is a bulletin sent from one host to another.

  7. What are three characteristics of multicast manual? (Choose three.)

    • The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255.
    • A single packet can be sent to a group of hosts.
    • Multicast manual tin be used by routers to exchange routing information.
    • The range of 224.0.0.0 to 224.0.0.255 is reserved to reach multicast groups on a local network.
    • Computers apply multicast transmission to asking IPv4 addresses.
    • Multicast messages map lower layer addresses to upper layer addresses.
      Explanation:

      Broadcast letters consist of unmarried packets that are sent to all hosts on a network segment. These types of letters are used to request IPv4 addresses, and map upper layer addresses to lower layer addresses. A multicast transmission is a unmarried packet sent to a group of hosts and is used by routing protocols, such every bit OSPF and RIPv2, to commutation routes. The accost range 224.0.0.0 to 224.0.0.255 is reserved for link-local addresses to achieve multicast groups on a local network.

  8. Which three IP addresses are private ? (Choose 3.)

    • 10.i.i.1
    • 172.32.5.2
    • 192.167.10.x
    • 172.xvi.4.4
    • 192.168.5.5
    • 224.6.6.6
      Explanation:

      The private IP addresses are within these three ranges:
      x.0.0.0 – 10.255.255.255
      172.16.0.0 – 172.31.255.255
      192.168.0.0 – 192.168.255.255

  9. Which 2 IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains? (Cull two.)

    • trunking
    • dual stack
    • encapsulation
    • tunneling
    • multiplexing
      Caption:

      At that place are three techniques to allow IPv4 and IPv6 to co-exist on a network. Dual stack allows IPv4 and IPv6 to coexist on the same network segment. Dual stack devices run both IPv4 and IPv6 protocol stacks simultaneously. Tunneling is a method of transporting an IPv6 packet over an IPv4 network. The IPv6 packet is encapsulated inside an IPv4 packet, similar to other types of data. Network Accost Translation 64 (NAT64) allows IPv6-enabled devices to communicate with IPv4-enabled devices using a translation technique similar to NAT for IPv4.

  10. Which of these addresses is the shortest abbreviation for the IP address:

    3FFE : 1044 : 0000 : 0000 : 00AB : 0000 : 0000 : 0057?

    • 3FFE : 1044 :: AB :: 57
    • 3FFE : 1044 :: 00AB :: 0057
    • 3FFE : 1044 : 0 : 0 : AB :: 57
    • 3FFE : 1044 : 0 : 0 : 00AB :: 0057
    • 3FFE : 1044 : 0000 : 0000 : 00AB :: 57
    • 3FFE : 1044 : 0000 : 0000 : 00AB :: 0057

  11. What type of address is automatically assigned to an interface when IPv6 is enabled on that interface?

    • global unicast
    • link-local
    • loopback
    • unique local
      Caption:

      When IPv6 is enabled on any interface, that interface will automatically generate an IPv6 link-local address.

  12. What are two types of IPv6 unicast addresses? (Choose two.)

    • multicast
    • loopback
    • link-local
    • anycast
    • broadcast
      Explanation:

      Multicast, anycast, and unicast are types of IPv6 addresses. In that location is no broadcast accost in IPv6. Loopback and link-local are specific types of unicast addresses.

  13. What are three parts of an IPv6 global unicast address? (Choose iii.)

    • an interface ID that is used to identify the local network for a particular host
    • 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 place the portion of the network address provided by a local administrator
    • an interface ID that is used to place the local host on the network
      Caption:

      There are iii elements that brand up an IPv6 global unicast accost. A global routing prefix which is provided by an Isp, a subnet ID which is determined by the organization, and an interface ID which uniquely identifies the interface interface of a host.

  14. An administrator wants to configure hosts to automatically assign IPv6 addresses to themselves by the employ of Router Ad messages, but also to obtain the DNS server accost from a DHCPv6 server. Which address assignment method should be configured?

    • SLAAC
    • stateless DHCPv6
    • stateful DHCPv6
    • RA and EUI-64
      Explanation:

      Stateless DHCPv6 allows clients to use ICMPv6 Router Advert (RA) letters to automatically assign IPv6 addresses to themselves, but then allows these clients to contact a DHCPv6 server to obtain additional data such as the domain name and address of DNS servers. SLAAC does non permit the customer to obtain additional data through DHCPv6, and stateful DHCPv6 requires that the client receive its interface address direct from a DHCPv6 server. RA messages, when combined with an EUI-64 interface identifier, are used to automatically create an interface IPv6 accost, and are office of both SLAAC and stateless DHCPv6.

  15. Which protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?

    • ARPv6
    • DHCPv6
    • ICMPv6
    • UDP
      Explanation:

      SLAAC uses ICMPv6 messages when dynamically assigning an IPv6 address to a host. DHCPv6 is an alternate method of assigning an IPv6 addresses to a host. ARPv6 does non be. Neighbor Discovery Protocol (NDP) provides the functionality of ARP for IPv6 networks. UDP is the transport layer protocol used by DHCPv6.

  16. Which two things can be adamant by using the ping command? (Cull 2.)

    • the number of routers between the source and destination device
    • the IP address of the router nearest the destination device
    • the average time information technology takes a packet to reach the destination and for the response to return to the source
    • the destination device is reachable through the network
    • the average time it takes each router in the path between source and destination to reply
      Explanation:

      A ping control provides feedback on the time between when an repeat request was sent to a remote host and when the repeat reply was received. This tin be a measure of network functioning. A successfulpingalso indicates that the destination host was reachable through the network.

  17. What is the purpose of ICMP letters?

    • to inform routers almost network topology changes
    • to ensure the commitment of an IP packet
    • to provide feedback of IP packet transmissions
    • to monitor the process of a domain name to IP address resolution
      Caption:

      The purpose of ICMP messages is to provide feedback about issues that are related to the processing of IP packets.

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

    • The host is cabled properly.
    • The default gateway accost 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.
      Caption:

      The IPv6 accost ::1 is the loopback address. A successful ping to this accost means that the TCP/IP stack is correctly installed. It does not hateful that whatsoever addresses are correctly configured.

  19. A user is executing a tracert to a remote device. At what betoken would a router, which is in the path to the destination device, finish forwarding the parcel?

    • when the router receives an ICMP Time Exceeded message
    • when the RTT value reaches zip
    • when the host responds with an ICMP Echo Answer bulletin
    • when the value in the TTL field reaches zero
    • when the values of both the Repeat Request and Repeat Answer letters reach zero
      Explanation:

      When a router receives a traceroute packet, the value in the TTL field is decremented by 1. When the value in the field reaches nil, the receiving router will not forward the packet, and will send an ICMP Time Exceeded message dorsum to the source.

  20. What field content is used past ICMPv6 to determine that a packet has expired?

    • TTL field
    • CRC field
    • Hop Limit field
    • Time Exceeded field
      Explanation:

      ICMPv6 sends a Time Exceeded bulletin if the router cannot frontwards an IPv6 packet because the bundle expired. The router uses a hop limit field to determine if the packet has expired, and does not have a TTL field.

  21. Fill in the bare.

    The decimal equivalent of the binary number 10010101 is149 .

  22. Fill in the blank.
    The binary equivalent of the decimal number 232 is 11101000

  23. Make full in the bare.
    What is the decimal equivalent of the hex number 0x3F?63

    Caption:
    1. Hex 0x3F is 63 in decimal.
      (3*xvi)+(15*1) = 63

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