AWS Certified Machine Learning Specialty Full Practice Exam from Udemy

UPDATED FOR 2024 with updated questions & answers, more detailed explanations, and more realistic questions.

Nervous about the AWS Certified Machine Learning Specialty exam? You should be. It's arguably the toughest certification exam AWS offers, as it not only tests AWS-specific knowledge, but your practical experience in machine learning and deep learning in general. It's tough to know what to expect on the exam before going in.

This practice exam offers a realistic, full-length simulation of what you can expect in the AWS MLS-C01 exam. It's not a "brain dump," but a complete, 65-question, 3-hour practice exam with original questions of the same style, topics, difficulty, and breakdown of the real exam. It's a great test of your readiness before you decide to invest in the real exam, and a great way to see what sorts of topics the exam will touch on. We also include a 15-question warmup test that will give you a rough idea of your readiness in just a half an hour.

The author of this exam, Frank Kane, is a popular machine learning instructor on Udemy who passed the AWS Certified Machine Learning exam himself on the first try - as well as the AWS Certified Big Data Specialty exam, which the Machine Learning exam builds upon. Frank spent over 9 years working at Amazon itself in Seattle, as a senior manager specializing in some of Amazon's early machine learning development.

Just like the real exam, this practice exam tests four different domains:

Data Engineering
Exploratory Data Analysis
Modeling
Machine Learning Implementation and Operations

You'll need deep and broad knowledge of SageMaker and AWS's other machine learning services, including Rekognition, Translate, Polly, and Comprehend. You'll need to know how to process big data using Kinesis, S3, Glue, and Athena. And you'll need a strong knowledge of AWS security, including use of KMS and IAM.

But AWS knowledge is not enough to pass this practice exam, or the real thing. You also need deep knowledge on data science, feature engineering and tuning your machine learning models. Do you really understand regularization techniques and how to use them? Do you really understand precision, recall, and AUC? Do you know how different deep learning models work, and how they are used? This practice exam will let you find out. Every question includes an explanation of the correct answer as well.

Don't risk hundreds of dollars and hours of your time on the AWS Certified Machine Learning Exam until you're sure you're ready for it. This practice exam is a good test of that readiness, and a good taste of what to expect. It's worth the effort - this AWS certification is the most elite one there is right now.

This practice exam is a bargain compared to the official AWS practice exam, and it's three times as long. Buy it now, and get some extra peace of mind as you head into your testing center.

Syllabus

This 15-question warmup test should give you a good idea of how prepared you really are for the full practice exam, and for the real one - without investing 3 hours in the process. We chose these questions to be representative of the domains covered by the real exam, and some of the more difficult topics you'll be expected to know on it. If you're surprised by the topics and level of detail you encounter, you know you have more preparation and studying to do.

The AWS Certified Machine Learning Specialty exam goes beyond AWS topics, and tests your knowledge in feature engineering, model tuning, and modeling as well as how deep neural networks work. You need to both have expert-level knowledge of AWS's machine learning services (especially SageMaker), and expert-level knowledge in machine learning and AI in general.

Simulate the real AWS Certified Machine Learning Specialty exam experience. You'll encounter the same number of questions, the same breakdown of topics, and a similar format to the real thing. Your ability to pass or fail this exam should be a good indicator of your readiness for the real thing.

When taking the real exam, some questions might sound similar to some of these practice questions, since they cover the same material. But they are not the same. If you see a question on the real exam that looks familiar, don't automatically select the same answer that you remember from this practice exam. Odds are the question is actually a little different, and has a different answer.

The actual exam is timed and you will have 3 hours, with no breaks, to complete it. You should find that 3 hours is more than sufficient, so take your time and read each question and possible answer carefully.
