An administrator is working with the 192.168.4.0 network, which has been subnetted with a
/26 mask. Which two addresses can be assigned to hosts within the same subnet? (Choose
two.)
A.
192.168.4.61
B.
192.168.4.63
C.
192.168.4.67
D.
192.168.4.125
E.
192.168.4.128
F.
192.168.4.132
Explanation:
Only the values of host with 67 and 125 fall within the range of /26 CIDR subnet mask, all
others lie beyond it.
C – D
These subnets use an increment of 64 (/26 converted to dotted decimal is 192, 256 – 192 = 64)
Using this increment, we can create the following subnets:
192.168.4.0
192.168.4.64
192.168.4.128
192.168.4.192
answer A is in the first subnet
answer B is the broadcast address of the first subnet (and therefore cannot be assigned to a host)
answer E is the network address of the third subnet
answer F is in the third subnet
only answers C and D are in the same subnet (the second subnet)
