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 site subsection to represent multiple geographical sites of the company, the sub-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 of subnets achieved per sub-site ?
16
Match the IPv6 address with the IPv6 address type. (Not all options are used.)
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.
Match each description with an appropriate IP address. (Not all options are used.)
Link-Local addresses are assigned automatically by the OS environment and are located in the block 169.254.0.0/16. The private addresses ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. TEST-NET addresses belong to the range 192.0.2.0/24. 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.
Refer to the exhibit. Match the network with the correct IP address and prefix that will satisfy the usable host addressing requirements for each network.
Network A needs to use 192.168.0.128 /25, which yields 128 host addresses. Network B needs to use 192.168.0.0 /26, which yields 64 host addresses. Network C needs to use 192.168.0.96 /27, which yields 32 host addresses. Network D needs to use 192.168.0.80/30, which yields 4 host addresses.
An IPv6 enabled device sends a data packet with the destination address of FF02::1. What is the target of this packet?
