Q.173

Exhibit:

The exhibit shows an IP address and its subnet mask. What is the last available host address for this IP subnet?

A.172.20.7.255

B.172.20.7.197

C.172.20.7.190

D.172.20.7.129

E.172.20.255.255

Answer: C

Explanation: In order to determine the last available host you will need to draw a vertical line just after the last contiguous subnet mask 1 bit. On the next line write the address that it to the left of the line and then to the right of the line place all 1s in the remaining spaces until the last free space. Place a 0 in this place. Convert the binary to dotted-decimal and this will be the last available host.

In this case the binary would be:

10101100 00010100 00000111 10 111110 This converts to

172.20.7.190
