1. Which 2 methods allowed the continued use of IPv4 even though the pool of IPv4 addresses are being exhausted? (choose 2) Answer Supernetting of routes Private addresses with Network Address Translation (NAT) Expansion of the IPv4 address range Subnetting using variable length Which of the following routes is a supernet route? Answer 10.1.10.0 /16 100.10.100.0 /8 150.20.2.0 /14 200.2.2.0 /26 The network address 192.168.1.0 will be subnetted with a subnet mask /28. Which of the following is a subnet address? Answer 192.168.1.40 192.168.1.98 192.168.1.110 192.168.1.176 Given a subnet mask 255.255.254.0, how many usable host addresses are available? Answer 126 254 510 1022 What subnet mask can be used in a network with 52 hosts with minimal waste of unused addresses? Answer 255.255.255.0 255.255.255.128 255.255.255.192 255.255.255.224 The routers are running RIPv1. Router B sends an update containing information about 192.168.3.224. What subnet mask will router A apply to this network? Answer /16 /24 /25 /27 The network 172.16.0.0 /16 is subnetted using a /24 subnet mask. What subnet mask can be applied to divide the subnet further into 6 equal sized subnets? Answer A network engineer is summarizing 2 groups of routes shown below. What summarization can be used for ALL the subnets? Group A 192.168.0.0 /30 192.168.0.4 /30 192.168.0.8 /30 192.168.0.16 /29 Group B 192.168.4.0 /30 192.168.5.0 /30 192.168.6.0 /30 192.168.7.0 /29 Answer 1. What is a supernet route? What is needed to propagate supernet routes? Answer Refer to the exhibit above. Given the network address block 192.168.1.0 /24, subnet and provide the IP addressing for the network topology using VLSM. The network requirements are:- o The HQ LAN1 will require 50 host IP addresses. o The HQ LAN2 will require 50 host IP addresses. o The Branch1 LAN1 will require 20 host IP addresses. o The Branch1 LAN2 will require 20 host IP addresses o The Branch2 LAN1 will require 12 host IP addresses. o The Branch2 LAN2 will require 12 host IP addresses. o The link from HQ to Branch1 will require an IP address for each end of the link. o The link from HQ to Branch2 will require an IP address for each end of the link. o The link Branch1 to Branch2 will require an IP address for each end of the link.
