CCNA sample Q clarification

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. B. C. D. FFFF.FFFF.FFFF E. F. All of the above

It looks like "none of the above" to me, but the stated answer was "A". Isn't a broadcast address?

No. Convert it in BITs and split according to subnet to network and host pieces: = 10101100 00011111 10 | 000000 11111111

Network = 10101100 00011111 10 Host = 000000 11111111

Good luck,
