Expert Recommendations by Role
Cloud Engineer / DevOps
Take AZ-900. MS-900 won't help with infrastructure roles.
IT Administrator (Small Business)
Take MS-900 first, then AZ-900. You'll likely manage M365 daily, Azure occasionally.
Help Desk / Support
Take MS-900. You'll troubleshoot Teams, Outlook, SharePoint more than VMs.
Career Changer (No IT Background)
Take MS-900 for easier entry, or AZ-900 for better long-term prospects.MS-900 is easier to pass, but AZ-900 opens more doors.
Sales / Consulting
Take both. Understanding the full Microsoft ecosystem helps credibility.
