While filling the header you have to give the title, summary, and other details. Title is an important thing because it should contain all the information about the question paper - to which year it belongs, to which class or year it belongs, to which college it belongs, to which board or university it belongs etc. You can see some sample question papers which are approved and published to get a feel of that. Regarding summary it should simply invite the person interested in seeing it and generally should start like - Are you interested to go through the question paper related to such and such course of such and such institution etc.
Generally it is preferred that we type the whole paper in the prescribed place but one can attach the PDF file also. The difference is that if you type it you might get more points as compared to simply attaching it.
Knowledge is power.
