Well worth it!
Many similar questions came up on the exam, so these questions are well worth your time. For those that feel it doesn’t cover enough I would say that trying SCS without at least SAA is not a good idea. There are also several DVA level questions on the exam around security. If you know SAA and DVA then these questions round out the security part of it well.
Thanks for the awesome review! We wish you all the best on your next certifications! 🙂
