Key

A)

Given a network

of
192.168.100.0
,
you need to create at least 4
usable
subnet
s which will support up to 30 host addresses each.

C

255.255.255.0

How many bits
need to be left in host field:

5

(2
5

=
32 hosts, 30 usable
)

How many bits need to be borrowed:

3

(2
3

=
8 subnets,
6 usable)

Custom
:

255.255.255.224

(255.255.255.11100000)

List the
following information for the 1
st

8
subnets

(including the Zero subnet)
