AWS Certification exams are tough nuts to crack. Starting right from the Foundational-level, they are built to test your awareness and practical experience in the domain. As every question are scenario-based, leaving you with almost no quick help to crack the exam. Speaking about AWS DevOps certification is a Professional-level certification exam, which makes it much tougher to crack than the Foundational and Associate level.
You will face around 75 Questions that are all scenario-based and tests your capability in the domain, to build automated solutions, and testing to get your job done within the cloud. It not only tests your grasp in AWS but how well you could perform DevOps by leveraging AWS. You would find it very difficult if you are not thoroughly prepared for the exam, practically. And for the same reason, I would recommend you to enroll in a good AWS DevOps course from Intellipaat. This course is designed to enhance your practical skills through guided projects.
If this is all completely new to you, then I would suggest you watch the following video on AWS DevOps.
