MS-721-Specific Tips

  • Deep-dive into Teams Phone and Direct Routing configuration—these are heavily tested domains; practice building dial plans, call routing rules, and emergency calling policies in a lab environment
  • Master PowerShell for Teams Phone management; know cmdlets for voice policies, calling policies, and Teams device management (Get-CsOnlineUser, New-CsTeamsCallPolicy, etc.)
  • Study Teams Rooms deployment end-to-end: hardware selection, software configuration, device provisioning, and lifecycle management—device management is a core domain
  • Practice troubleshooting scenarios using Teams Admin Center and real-world call quality issues; the moderate difficulty (2.9/5) suggests practical troubleshooting will be tested alongside configuration
  • Focus on Direct Routing and SIP trunk configurations, especially emergency calling compliance and failover scenarios—these are critical for production implementations
  • Review meetings, webinars, and town halls features in context of organizational requirements (capacity, security, compliance); understand the difference between native Teams and Direct Routing quality considerations
  • Use the 268 available practice questions strategically—focus on weak domains first, then do full-length simulations under timed conditions to simulate exam pressure
