Studying for the CCNA exam, I came across the following sample question:
Which of the following is an example of a valid unicast host IP address? A. 172.31.128.255./18 B. 255.255.255.255 C. 192.168.24.59/30 D. FFFF.FFFF.FFFF E. 224.1.5.2 F. All of the above
It looks like "none of the above" to me, but the stated answer was "A". Isn't 172.31.128.255/18 a broadcast address?

No, since 172.31.128.255/18 means 172.31.128.0 - 172.31.191.255

No. Convert it in BITs and split according to subnet to network and host pieces:
172.31.128.255 = 10101100 00011111 10 | 000000 11111111Network = 10101100 00011111 10 Host = 000000 11111111
Good luck,
Mike
