the answers for the question below is 1,3,4
Can someone help to explain why 2 and 6 not valid host address?
What are three valid host addresses given a subnet mask of 255.255.254.0? (Choose three.)188.8.131.52.25184.108.40.206.25220.127.116.11.04.192.168.162.2518.104.22.168.2522.214.171.124.0
Go to Solution.
a valid host address means no broadcast address and no subnet address can be used and means that not all 9 bits of host portion can be all 1 or all 0.
you need to write in binary the last two octets
33.255 = 001000||1 1111 1111
as you can see all last 9 bits are set to 1 so this is a broadcast address of subnet 126.96.36.199/23
62.0 in binary = 0011 111||0 0000 0000
here all last 9 bits are set to zero this is a subnet address 188.8.131.52/23
question five is like 2)
Hope to help
