70-216 MS exam

Hi all!

I faild to pass 70-216 exam last Friday. MS has changed the form of exams recently and now you can find a lot of questions that look like real configuration windows where you need to supply values. This is fine, just letting you know to be prepared and have more time with a mouse in your hands 🙂 I faild on questions about DNS configured with round robin function. My question is: what is round robin and how it affects DNS?

Thanks in advance
