Hi Sandeep. For the purposes of the exam, the order of the artifacts is not relevant. The exam is largely situational and will throughly test your knowledge in terms of "Agile Mindset." I don't recall any questions that were straightforward, such as "Define the third artifact in an Iteration" or "The Burn Down Chart is the___artifact in a Sprint."
However, you should thoroughly understand what a Burn Down and Burn Up chart are, what they are used for and how to interpret them. And of course, know what a Product Increment is and when it occurs in an iteration.
