DNS topic, bigger than i thought!!?

Hi All,
I have been studying the DNS topic for the 70-410 exam. Before I began to study this topic I assumed it wouldn't be so big but i was completely wrong. There were bits which I grasped straightaway and some parts that confused me but I watched some youtube vids to cover these.
Thinking I'm really confident after reading the chapter in Mastering 2012 r2 book, I tried the DNS questions on the Transcender practice exams and got absolutely hammered. What will be the requirements for DNS on this exam? I've seen the exam objectives but find it vague. How did you people deal with this topic? what parts did you study?
thanks
