In my experience, "no solution at all" is already the default. When people choke on questions it is because they get stuck trying to guess at what you want, and panic thinking it must be some clever trick they don't recognize. Becasue we've all seen a million tricks and forgotten most of them.

If you're happy with just getting it done quick and dirty, at least as a start, then telling them so is obviously better than not doing so. Beyond that, anything more about what you want will help trigger their thinking in terms of the right approach. Unless of course you really are looking for some clever trick (and I have certainly seen those annoying questions).
