Question

The 165 Project Company is setting up a new headquarters in Downtown Springfield. As such, they need to set up a network of publicly available services on that network. Please read the rest of the instructions and answer carefully, the answer boxes will be doing string matches, to the best of your ability. You will get three submissions chances to get it right. They have bought the public IP subnet of 192.165.1.192/26 to be used. You need to divide that subnet into three subnets. One for infrastructure that can support 14 nodes, one for public services that can support 30 nodes, and one for private services that can support 14 nodes. The lowest numeric value IPs should be used for the private services. They will need you to configure a ISC DHCP server that will hand out the last half of each subnets IPs except the last usable IP (that will be used as the default-gateway. The DHCP server will also be the Name Server (DNS Server) (named net-srv.infra.165pro.net) for the three subnets as well. The IP of the DH

Answer 1

The 165 Project Company's subnet can be divided into three: a /28 for private services, a /27 for public services, and another /28 for infrastructure.

Step-by-step explanation:

The correct answer is option Computers and Technology. The 192.165.1.192/26 subnet can be divided into three smaller subnets to accommodate the different node requirements for the 165 Project Company.

To support 14 nodes, the infrastructure subnet needs a minimum of 16 IPs (14 for nodes, one for network address, and one for broadcast), hence a /28 subnet.

Similarly, the public services subnet requires at least 32 IPs, so it needs to be a /27 subnet, whereas the second /28 subnet will be for the private services.

The lowest subnet, 192.165.1.192/28, will be for private services with the range 192.165.1.192 - 192.165.1.207. The remaining IPs after the network, broadcast, and default gateway IP, from 192.165.1.198 to 192.165.1.206, are available for DHCP allocation.

The next subnet, 192.165.1.208/27, for public services, spans from 192.165.1.208 - 192.165.1.239. DHCP can allocate from 192.165.1.225 to 192.165.1.238, just before the default-gateway.

The final subnet, 192.165.1.240/28, supports the infrastructure and has an IP range from 192.165.1.240 - 192.165.1.255, with DHCP assigning from 192.165.1.248 to 192.165.1.254, excluding the last IP for the default-gateway.

For the ISC DHCP server configuration, the IP of the DHCP and DNS server, net-srv.infra.165pro.net, will be one of the IPs assigned outside the DHCP range but within each subnet's range.

The DHCP server will allocate the latter half of each subnet's IPs, excluding the last IP (reserved for the default-gateway), and will serve as the DNS server.
