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. A company is deploying an IPv6 addressing scheme for its network. Each number or letter in the address represents 4 bits, so the prefix-length is /60.Ģ7. Which three addresses are valid public addresses? (Choose three.)Įxplanation: All the addresses have the part 2001:0DB8:BC15:00A in common. The administrator knows immediately that this IP will not work. The administrator sends a request for the IP address for the end device in school B and the response is 192.168.25.10. The network administrator of school A configures the end device with the IP address 209.165.201.10. The videoconferencing is conducted between two end devices through the Internet. A high school in New York (school A) is using videoconferencing technology to establish student interactions with another high school (school B) in Russia.
Network D needs to use 192.168.0.80/30, which yields 4 host addresses.ġ8. Network C needs to use 192.168.0.96 /27, which yields 32 host addresses. Network B needs to use 192.168.0.0 /26, which yields 64 host addresses. What is the network address and subnet mask of the second useable subnet?Įxplanation: Network A needs to use 192.168.0.128 /25, which yields 128 host addresses. An administrator wants to create four subnetworks from the network address 192.168.1.0/24. Match the subnetwork to a host address that would be included within the subnetwork. How many equal-sized subnets are created?ĥ. A network administrator subnets the 192.168.10.0/24 network into subnets with /26 masks. Which subnet mask would be used if 5 host bits are available?Ĥ. How many valid host addresses are available on an IPv4 subnet that is configured with a /26 mask?ģ. The prefix length is the number of consecutive 1s in the subnet mask.
