Nice question really had to dig deep into my memory to, well answer the question.
If everything seems to be going well, you have obviously overlooked something.

Easy question - if you know the answer.
(I had to look!)

This was so easy I answered right away without hesitation. Then, I noticed it was a two point question and that gave me doubt. Those two point questions always have some twist to them. So, I looked up the definition of deterministic to make sure I understood the word correctly.
Definition:
In computer science, a deterministic algorithm is an algorithm which, in informal terms, behaves predictably.
Also, for those interested, Steve had a nice post about this function on June 28, 2011:

I got it right but I was scared to push that submit button.

Great question as it taught me about Hashbytes, which is something I did not know about.

Nice question, but the documentation linked to doesn't really explain anything!

Nice question, but quite easy as hash functions are deterministic by design.

An unexpected adventure into hashing - Hash Tuesday anyone?
Thanks for the stimulating question Steve.
Please don't go. The drones need you. They look up to you.
