Certification Overview
This exam focuses on enterprise Teams voice infrastructure: configuring Direct Routing to on-premises Session Border Controllers, managing Microsoft Teams Phone (cloud voice), optimizing network quality for real-time communications, and troubleshooting PSTN connectivity and call routing issues. Heavy emphasis on PowerShell automation, licensing models, and hands-on configuration over conceptual knowledge.

Who Should Take This Exam
Microsoft Teams administrators and infrastructure engineers with 1-3 years of Teams administration experience who are transitioning into voice/telephony specialization. Requires solid understanding of Teams fundamentals and networking concepts, but not necessarily prior VoIP experience.

MS-720-Specific Tips
- Build hands-on Direct Routing labs in a test tenant—configure SBC, voice routes, and failover. This domain dominates the exam and requires practical experience, not just theory.
- Master PowerShell for Teams voice cmdlets (New-CsOnlineApplicationInstance, New-CsCallQueue, Set-CsTeamsPhoneNumberAcquisitionType). ~15-20% of questions test automation and scripting.
- Study network optimization for Teams voice: QoS tagging, bandwidth requirements, jitter/latency thresholds. The 'Optimize network performance' domain is light (1 question) but foundational to everything else.
- Practice troubleshooting call flow scenarios using call analytics and logs. Focus on PSTN connectivity failures, Direct Routing routing issues, and Teams client problems.
- Deep dive into licensing and PSTN options (Calling Plans vs. Direct Routing tradeoffs). Exam includes licensing decision scenarios, not just configuration.
- Review Session Border Controller (SBC) requirements and certification list. Know which SBCs are certified, basic SBC configuration concepts, and why media bypass matters.
- Take 3+ full practice exams (126 questions suggests 2-3 official practice sets exist). Target 75%+ on practice exams before sitting; the 2.8 difficulty is misleading—domains are interconnected.
