C
SharePoint Online
Why wrong: SharePoint provides document storage and lists but lacks built-in video conferencing and a team calendar as a single workspace.
D
OneNote
Why wrong: OneNote is a digital notebook for note-taking, not a comprehensive workspace for file storage, calendars, and video meetings.

Correct answer & explanation
✓
Microsoft Teams
Microsoft Teams is the correct answer because it provides a single, integrated workspace that combines persistent chat, file storage (via SharePoint), collaborative editing on lists (via SharePoint or Planner), a shared calendar, and built-in video meetings. This eliminates the need to switch between separate apps for each task, fulfilling all the sales team's requirements in one experience.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often pick SharePoint Online because they associate it with document storage and lists, forgetting that Teams integrates those features with video meetings and a shared calendar, making it the single, integrated solution the question explicitly requires.
Detailed technical explanation
How to think about this question
Under the hood, Teams leverages SharePoint Online for file storage (each channel has a corresponding SharePoint document library), Exchange Online for calendar and meeting scheduling (via the Graph API), and Azure Communication Services for real-time video and audio. The shared calendar in Teams is actually a group calendar backed by an Exchange Online mailbox, and lead lists can be managed using the Lists app or integrated Planner tasks, all surfaced through the Teams client without requiring users to navigate away.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
