Can someone help me understand why the answer is "B". Thanks.

You work as the network administrator at The network consists of a single Active Directory domain named The network contains a Dynamic Domain Name System (DDNS) server named Server01 and a File Server named Server02. Server01 uses the IP address and Server02 uses the IP address

You Windows XP Professional client computer is named Client01. Client01 is configured with the IP address and a gateway address of You are unable to connect to Server02. You need to access files on Server02.

What should you do?
a. Change the IP address on Server01 to
b. Change the IP address on Client01 to (Correct Answer)
c. Change the IP address on Server02 to
d. Change the gateway address on Client01 to

    It always helps to write things out in binary:

    Remember, you can't use all 0s (network address) or all 1s (broadcast address) for a host. That's why you have to subtract two when determining the max number of hosts on a subnet.

    Thanks for the reply, but I still don’t understand why we have to change the IP address for Client01 from to If the subnet mask is /27, shouldn’t they all be able to communicate?

    11111111.11111111.11111111.11100000 = /27
    11000000.10101000.00000010.10011111 = (client01)
    11000000.10101000.00000010.10001111 = (server01)
    11000000.10101000.00000010.10010001 = (server02)
    11000000.10101000.00000010.10010001 = (default gateway)

    11000000.10101000.00000010.10011110 =

    See the note at the bottom of my previous post. All the host bits are set to 1, which is the broadcast address for that subnet. The broadcast and network addresses are reserved for their respective purposes. Therefore, you can't set a host's IP to the broadcast address.
