This course consists of:
Answer Key: why this, not that + clickable links to supporting materials (docs, blogs, wikis, and videos).
Please note that provided two practice tests are mock exams, not brain dumps. The tests are designed to replicate the style, topics, and complexity (or simplicity ;8-) of the real-world AWS certification exams. The number of questions for each Domain Topic is chosen to match current AWS exam guidelines (2020 AWS MLS-C01). The sentence length and structure of questions are adjusted to match examples from the AWS Sample Exam Questions document.
The multiple-choice questions are written with plausible distractors, using memory + application method that tests students' knowledge of principles and facts in real-life situations.
The question subjects (eg. A Machine Learning Specialist, etc) and the question conditions (eg. "to address this concern", "choose the BEST/most EFFICIENT way to", "to improve/minimize" etc) also follow the AWS Sample Exam Format. Candidates preparing for the exam will expend about the same time and apply about the same mental effort understanding the question as they would in the real test center environment.
In the end, I have also tried to make the presentation interesting, in some cases even fun, to maximize the probability you will retain the knowledge ;8-) In a few places, I have been adding graphics/figures to illustrate the question, hoping that might improve your understanding of the subject matter.
P.S. I recommend you first take the AWS Cloud Practitioner Exam. There are two advantages: (i) you get familiarized with the AWS Exams format and physical exam center environment, and (ii) you can get rolling 50% off discounts on all future exams! Also, if you are not a native English speaker, you can apply online for a 30-minute extension ("ESL+30 minutes") to the exam time from your CertMetrics account.
P.S.S. A final comment about the validity of the answers: each practice exam question is followed by an answer, explanation of the answer, and explanation of why other multiple choices are wrong. The clickable link(s) (between two and four) to the free online resources are provided (AWS documentation, other documentation, pdf articles, blogs, and videos). Some questions on a real AWS Certification Exam are poorly worded. (Sorry -- that is not my fault.) Sometimes two multiple-choice options appear to be an almost equally acceptable answer. You should not get too worked up over that: if you use these practice exams as one of the building blocks of your studies, you should be able to demonstrate your broad ML knowledge in a job interview and you should be able to pass the AWS Machine Learning Specialty Exam (75% passing score required).
