What’s included

• Overview: format, audience, readiness checklist, compact study plan
• Syllabus: objective-by-domain outline (cloud concepts, core services, security/governance, pricing/TCO/SLAs)
• Cheatsheet: high-yield tables (global infrastructure, identity/governance, storage/compute/networking basics, SLA math)
• Practice: app embed with suggested progression and pacing tips
• FAQ: common candidate questions and scenario heuristics
• Resources: official docs and pricing/SLAs/trust center links
• Updates: this changelog page

Impacted areas: Syllabus • Cheatsheet • Practice • Resources • Copy

How we version changes

• Patch updates (typos, minor clarifications): increment patch (e.g., v1.0.1).
• Objective re-mapping / added sections: increment minor (e.g., v1.1).
• Major blueprint shifts (Microsoft revision): increment major (e.g., v2.0).

We align to Microsoft’s published exam objectives and product naming. When those change, we update the syllabus mapping first, then mirror adjustments across cheatsheet and practice coverage.
