If that's the activity you had to do, then congratulations you should score 100%.
It seems very odd that your tutors would make you ask on a forum what DSS are. Are you sure that's really what they said? The normal approach teachers take is to explain the subject or where in the course book to read, then ask you questions, often saying you have to express it in your own words (to stop you just copying the relevant section directly out of the book).
If your tutors really did make you ask about the subject they're supposed to be teaching you on a forum, instead of teaching it themselves, then you need to question why they're being paid to teach you, because they aren't doing that. You should raise a formal complaint that the teachers are skiving off and not doing their jobs properly.
Of course, if you're going to do that, then you need to be 100% certain of your facts, and that the reason you don't know anything isn't down to you goofing around.
