1. Foundational Principles & Core Azure Concepts

Phase 1 establishes the mental models you'll use throughout your Azure development career. Before diving into specific services, you need to understand:

• How to study effectively (Section 1.1)
• What the exam actually tests (Section 1.2)
• Core Azure concepts that underpin all services (Section 1.3)
• The shared responsibility model (Section 1.4)
• Essential development tools (Section 1.5)

These foundational concepts are referenced throughout later phases. Time invested here pays dividends when you encounter scenario questions that require reasoning from first principles.
