            Incorrect

            Link-Local addresses are assigned automatically by the OS and are located in the block 169.254.0.0/16. The private address ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. The addresses in the block 240.0.0.0 to 255.255.255.254 are reserved as experimental addresses. Loopback addresses belong to the block 127.0.0.0/8.

            Hint

            Link-Local addresses are assigned automatically by the OS and are located in the block 169.254.0.0/16. The private address ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.

                    Incorrect

                    FF02::1:FFAE:F85F is a solicited node multicast address.
                    2001:DB8::BAF:3F57:FE94 is a global unicast address.
                    FF02::1 is the all node multicast address. Packets sent to this address will be received by all IPv6 hosts on the local link.
                    ::1 is the IPv6 loopback address.
                    There are no examples of link local or unique local addresses provided.

                    3. Question
                    2 points
                    Which two types of devices are typically assigned static IP addresses? (Choose two.)
                    Correct

                    Incorrect

                    Servers and peripherals are often accessed by an IP address, so these devices need predictable IP addresses. End-user devices often have dynamic addresses that are assigned. Hubs do not require IPv4 addresses to operate as intermediary devices.

                    1 points

                    Fill in the blank.
                    The 8-digit binary value of the last octet of the IPv4 address 172.17.10.7 is …………………. .

                    Correct

                    Incorrect

                    7 = 4 + 2 + 1 = 00000111

                    Hint

                  • Question 5 of 14

                    1 points
                    In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?
                    Correct

                    Incorrect

                    Stateless Address Autoconfiguration (SLAAC) can be used as an alternative to DHCPv6. In this approach, a router provides global routing prefix, prefix length, default gateway, and DNS server information to a host. The host is not provided with a global unicast address by SLAAC. Instead, SLAAC suggests that the host create its own global unicast address based on the supplied global routing prefix. ARP is not used in IPv6. ICMPv6 messages are used by SLAAC to provide addressing and other configuration information. EUI-64 is a process in which a host will create an Interface ID from its 48-bit MAC address.

                    1 points

                    Fill in the blank.
                    The last host address on the 10.15.25.0/24 network is …………………. .

                    Correct

                    Incorrect

                    The host portion of the last host address will contain all 1 bits with a 0 bit for the lowest order or rightmost bit. This address is always one less than the broadcast address. The range of addresses for the network 10.15.25.0/24 is 10.15.25.0 (network address) through 10.15.25.255 (broadcast address). So the last host address for this network is 10.15.25.254.

                    Hint

                    1 points
                    What is the prefix length notation for the subnet mask 255.255.255.224?
                    Correct

                    Incorrect

                    The binary format for 255.255.255.224 is 11111111.11111111.11111111.11100000. The prefix length is the number of consecutive 1s in the subnet mask. Therefore, the prefix length is /27.

                    Hint

                    The binary format for 255.255.255.224 is 11111111.11111111.11111111.11100000. The prefix length is the number of consecutive 1s in the subnet mask. Therefore, the prefix length is /27.

                          A global IPv6 unicast address contains three parts. The Global Routing Prefix of an IPv6 is the prefix or network portion of the address assigned by the provider, such as an ISP, to a customer or site. The Subnet ID Field is used by an organization to identify a subnet within its site. The interface ID field of the IPv6 Interface ID is equivalent to the host portion of an IPv4 address.

                          1 points
                          Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?
                          Correct

                          Incorrect

                          The tunneling migration technique encapsulates an IPv6 packet inside an IPv4 packet. Encapsulation assembles a message and adds information to each layer in order to transmit the data over the network. Translation is a migration technique that allows IPv6-enabled devices to communicate with IPv4-enabled devices using a translation technique similar to NAT for IPv4. The dual-stack migration technique allows IPv4 and IPv6 protocol stacks to coexist on the same network simultaneously.

                          The network portion of the address 172.16.30.5/16 is …………………. .

                          Correct

                          Incorrect

                          A prefix of /16 means that 16 bits are used for the network part of the address. The network portion of the address is therefore 172.16.

                          Correct

                          Incorrect

                          A double colon (::) can replace any single, contiguous string of one or more 16-bit segments (hextets) consisting of all 0s, and can only be used once per IPv6 address. Any leading 0s (zeros) in any 16-bit section or hextet can be omitted.

                          An IPv6 enabled device sends a data packet with the destination address of FF02::1. What is the target of this packet?​
                          Correct

                          Incorrect

                          This address is one of the assigned IPv6 multicast addresses. Packets addressed to FF02::1 are for all IPv6 enabled devices on the link or network. FF02::2 is for all IPv6 routers that exist on the network.

                          Correct

                          Incorrect

                          Link-local addresses have relevance only on the local link. Routers will not forward packets that include a link-local address as either the source or destination address.

                          1 points
                          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 for this ping command?
                          Correct

                          Incorrect

                          The ping command is used to test connectivity between hosts. The other options describe tasks not performed by ping. Pinging the default gateway will test whether the host has the capability to reach hosts on its own network and on other networks.
