Top Tips for Passing the AWS AI Certified Practitioner Exam

I just passed the AWS AI Certified Practioner Exam and became one of the recipients of the Early Adopter Badge. In this blog, I will share my tips and tricks to help you pass the exam.

Understanding the AWS AI Practitioner Exam

The AWS Certified AI Practitioner exam is designed to give you a foundational knowledge of Artificial Intelligence(AI) and Machine Learning (ML) concepts and practical applications and key AWS services. Think of it as your AI 101 with an AWS twist. It covers four main domains, including:

• Machine Learning Basics: Understanding AI/ML concepts and their real-world applications.

• AWS AI Services: Key services such as Amazon SageMaker, Rekognition, Comprehend, Lex, and Polly.

• Responsible AI Practices: Ethical considerations and best practices in AI implementations.

• Model Training and Deployment: Understanding the end-to-end AI/ML workflow.

Note: The AWS AI Practioner Exam consists of 65 questions with a 90-minute duration.

Pro tip! Keep an eye on the AWS website for possible discounts on exam vouchers! When I took the exam, it had 50% discount and a free retake - a great deal if you need a second shot!

• AWS Builder Training Videos – These free video resources provided hands-on demonstrations and real-world use cases of AWS AI services, making it easier to understand complex concepts.

• AWS Training Live on Twitch – Training video resources from AWS experts

• AWS Skill Builder – I highly recommend creating an AWS Skill Builder ID and enrolling in the Exam Prep Standard Course: AWS Certified AI Practitioner (AIF-C01). This comprehensive course covers all essential topics and provides exam tips to help you succeed.

• AWS AI/ML Workshops – Participating in hands-on workshops helped me gain practical insights into real-world AI implementations, including topics such as building machine learning models, deploying AI services, and optimizing cloud infrastructure for AI workloads.

• AWS Whitepapers and Documentation – Reading AWS whitepapers helped me grasp fundamental AI concepts and understand how AWS services can be applied in real-world scenarios.

• AWS Machine Learning Blogs – Reading AWS whitepapers helped me stay updated on AWS AI/ML Innovations. It also provides tutorials, hands-on-demos and guides to AWS AI/ML services.

• AWS Free Tier – Hands-on practice with AWS AI services to gain practical experience in deploying and managing AI models.

  
  
  
  

3. Practice Exams

Taking practice exams was crucial to assess my readiness. I used resources like:

• AWS Official Practice Exams – These provided a benchmark of my knowledge and highlighted areas that needed improvement.

  
  

4. Hands-On Projects

To reinforce my understanding, I worked on small projects utilizing AWS AI services such as:

• Building a chatbot using Amazon Lex

• Performing sentiment analysis with Amazon Comprehend

  
  

Exam-Day Tips

On the day of the exam, I followed these key strategies to ensure a smooth experience:

• Time Management: I carefully allocated time to each question, ensuring I didn’t spend too long on any single one. If you're not sure or don't know the answer, mark the question and go back again to review it.

  
  

• Elimination Technique: When uncertain about an answer, I used the process of elimination to narrow down options.

• Reviewing Marked Questions: I revisited flagged questions to double-check my answers before submitting.

  
  

Key Takeaways

Reflecting on my journey, here are a few key takeaways:

1. Hands-on Practice is Key: Practical experience with AWS AI services helped reinforce theoretical knowledge.

2. Understand Core Concepts: Don’t just memorize; focus on understanding core AI/ML concepts and how they apply to AWS services.

3. Stay Updated: AWS frequently updates its services, so keeping up with new features and best practices is essential.

Conclusion

Earning the AWS Certified AI Practitioner certification has strengthened my knowledge in AI and ML, positioning me for further growth in cloud-based AI solutions. If you’re considering taking this exam, I encourage you to adopt a similar structured approach, create an AWS Skill Builder ID, enrol in the recommended courses, and participate in AWS AI/ML workshops to gain hands-on experience and achieve success.

I hope this blog provides you with valuable insights and inspiration for your AWS AI certification journey. Good luck!
