You posted this to the 'Document' area, which is really meant for how-to related posts. I am also going to move this over to the Education area of the forums too, as that is the appropriate place for this. That being said, you want to start with the following:
That will give you all of the basics you need to know, as far as preparation, you need to be familiar with the product, we recommend having worked with things for at least a year, but you may be able to review all the Help documentation and other guides and be prepared well enough if you understand the material and can apply the information to real-world use cases etc. That is about the best I can offer, as certficate holders are not allowed to discuss specific questions etc. on the exam, the above link is to provide that information to you, so you can prepare. Oh, I would recommend the training courses as well if you have not already done those too.
