MS-900 Describe Microsoft 365 apps and services Practice Question
A global sales team uses Microsoft Teams for communication. They need to automate business workflows such as sending approval requests when a new lead is created in Dynamics 365. Which Microsoft 365 service should they integrate with Teams?
⚠ Common exam trap
Test-takers frequently confuse Power Automate with Power Apps, mistakenly thinking that building a custom app is necessary for workflow automation, whereas Power Automate is the dedicated service for no-code/low-code process automation.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Power Automate
Power Automate (Option B) is the correct service because it is designed specifically for automating business workflows across Microsoft 365 and third-party services. When a new lead is created in Dynamics 365, a Power Automate flow can trigger an approval request in Teams, enabling seamless process automation without custom code.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Power Apps
Why it's wrong here
Power Apps is a low-code application development platform used to build custom canvas apps or model-driven apps for specific business needs, such as a mobile client for tracking deals. While it can be embedded in Microsoft Teams and can call Power Automate flows, its primary purpose is creating user interfaces and business logic, not orchestrating automated workflows or approvals. Therefore, it is not the correct tool for automating approval processes within Teams and Dynamics 365.
- ✓
Power Automate
Why this is correct
Power Automate is the correct choice because it is Microsoft's dedicated workflow automation service, enabling users to create cloud flows that connect to hundreds of services, including Microsoft Teams and Dynamics 365. For a global sales team, you can design an approval flow triggered by a new lead or a Teams message, automatically routing the approval request to the appropriate manager and tracking its status in real time. It provides prebuilt templates for approval scenarios and supports both automated and manual triggers, making it the ideal solution for streamlining sales communications and approvals.
- ✗
Power BI
Why it's wrong here
Power BI is a business analytics and data visualization tool that allows you to create interactive dashboards and reports from various data sources, such as Dynamics 365 sales records. Although Power BI reports can be embedded in Teams for visibility, Power BI does not execute actions, send messages, or manage approval workflows. It is designed for analysis and insight, not for automating business processes, so it cannot fulfill the requirement of creating automated workflow for the sales team.
- ✗
Power Virtual Agents
Why it's wrong here
Power Virtual Agents is a tool for building intelligent chatbots that can converse with users in natural language and can be deployed within Microsoft Teams to handle FAQs or simple customer queries. While a bot built with Power Virtual Agents can trigger a Power Automate flow to perform backend actions, the platform itself is not a workflow automation tool. It focuses on creating conversational experiences, not on automating multi-step business processes like approvals, making it incorrect for this scenario.
