I'm not losing sight of that, actually. In fact, I mentioned this in an
earlier post. I'm simply trying to correct the couple of people who
think that D is technically correct. This is a pretty typical question
for a Cisco test, and you'd definitely want to answer D in that
situation. However, there were a few people that seemed to think that D
was actually a valid answer given that question, and it isn't.
Splitting hairs, I know, but I just wanted to make sure they understood
my point.
Then again, maybe I need to take a nap! :-)

I think you are losing sight of the real question, which is right on a
cisco
exam! That can ONLY be D. Whether this is the phrasing you would use
in a
production environment is totally irelevant.
