What makes the DEA-C01 hard
DEA-C01 is not a theory exam. The scenarios are practical: a Glue job failing silently, a Kinesis stream dropping records, a Lake Formation permission not behaving the way it should. You need to know what to do, not just what the service is called, which is what separates candidates who pass from candidates who know AWS but have not studied the exam.
65 questions in 130 minutes, 720 out of 1000 to pass. This pack has 366 practice questions covering the AWS service combinations and specific scenarios that keep coming up, with no filler and no generic cloud questions.
