AWS Cloud Practitioner Study Session Two

December 27, 2025

I am taking the AWS Cloud Practitioner Exam in approximately eight days and want to ensure I am prepared. This series will serve as non-exhaustive note taking for the information that I am internalizing as I go.

Study materials:

• Free Code Camp Preparation
• AWS Certified Solutions Architect Practice Tests
• AWS Cloud Practitioner Essentials
• AWS Documentation
  • What is Cloud Computing?
  • Shared Responsibility Model
  • Regions and Availability Zones
• ChatGPT
