CIT 240 3.5.5 LAB QUESTIONS AND
ANSWERS WITH SOLUTIONS 2024
You are configuring the IP addresses of the SFO router FastEthernet interfaces. Subnet 1 (connected to
FasEthernet0/0) has 1178 hosts and Subnet 2 (connected to FastEthernet0/1) has 508 hosts. Your task in
this lab is to subnet the 172.16.0.0 network to provide sufficient host address for both subnets while
minimizing wasted IP addresses.
Complete the following tasks:
Choose one subenet mask for each subnet. The masks should provide for enough host addresses without
wasting IP addresses. - ANSWER SFO>enable
SFO#configure terminal
SFO(config)#interface FastEThernet0/0
SFO(config-if)#ip address 172.16.15.254
255.255.248.0
SFO(config-if)#no shutdown
SFO(config-if)#interface FastEthernet0/1
SFO(config-if)#ip address 172.16.17.254
255.255.254.0
SFO(config-if)#no shutdown
SFO(config-if)#exit
SFO(config)#exit
SFO#copy run start
Assign IP addresses and correct subnet masks to the SFO interfaces connected to the switches (in this
order):
1. For FastEthernet0/0, use the second possible
subnet and the last address on the subnet.
2. For FastEthernet0/1, use the next available
subnet that does not overlap and the last
address on the subnet. - ANSWER To determine which subnet mask will work for the 172.16.0.0
network, first look at the number of hosts required for each subnet:
