RHCSA 7 books

I have decided to make a slight career path change down the Linux route. My day to day activities vary with their depth into Linux. I'm looking to get a good Linux cert and from what I'm reading, the RHCSA is a good route to take. I was looking to buy a book but it looks like the ver 7 material for the new test isn't covered in any of the books out on Amazon. Should I just pick up one of the following books and supplement with the new material from Red Hat's documentation?

If you follow the objectives from the exam from Red Hat and know how to perform them, you should pass.
