📋 Channel Type Decision

Question Standard Private Shared
All team members need access? ✅ ❌ ❌
Subset of team members only? ❌ ✅ ❌
Cross-team collaboration? ❌ ❌ ✅
External org collaboration? ❌ ❌ ✅
Separate SharePoint site? ❌ ✅ ✅
Guest access supported? ✅ ✅ ❌
Uses B2B direct connect? ❌ ❌ ✅

📅 Meeting Type Decision

Need Recommendation
Team standup (10 people, interactive) Meeting

🔑 Policy Assignment Hierarchy

Policies are applied in this priority order (highest to lowest):

flowchart TD
    P1["1️⃣ Direct User Assignment\n(Highest priority)"]
    P2["2️⃣ Group Assignment\n(If user is in a group with policy)"]
    P3["3️⃣ Global (Org-wide Default)\n(Lowest priority — applies to everyone)"]

    P1 --> P2 --> P3

⚠️ Exam Caveat: If a user has a directly assigned policy AND belongs to a group with a different policy, the direct assignment wins.

⚠️ Common Exam Traps

Trap Correct Answer
“Where to configure Conditional Access for Teams?” Entra admin center — target the Office 365 cloud app
“Where to restrict M365 group creation?” PowerShell (Entra ID) — NOT M365 admin center UI
“Shared channels support guest access” False — shared channels use B2B direct connect, NOT guest access
“Private channel files are on the team’s SharePoint site” False — private channels get their own SharePoint site collection
“CQD shows real-time data” False — CQD data has a processing delay; use real-time analytics for live data
“Support Specialist can see all user analytics” False — Specialist sees per-user only; Engineer sees all users
“Town halls support interactive chat” False — Town halls only support Q&A, not full chat
“Meeting templates set defaults; meeting policies enforce limits” True — templates can lock settings; policies apply to all meetings for a user
“Teams Phone Resource Account license has a cost” False — it’s a free license
“Expiration policies auto-delete groups immediately” False — owners get notifications at 30, 15, and 1 day before expiration
“Webinars don’t require registration” False — registration is required for webinars
“Copilot works without transcription” False — Copilot in meetings requires transcription to be enabled
“Information barriers use group membership” False — IB uses user segments based on Entra ID attributes

Latency (round-trip) < 100 ms > 500 ms
