PL-900 Practice Question: Describe the business value of Microsoft Power Platform
A retail company wants to reduce the time store managers spend on manual inventory reporting. Currently, managers use paper forms and email to submit daily stock counts, which then need to be manually entered into a central system. This process is error-prone and delays replenishment. The company wants a solution that automates data entry, provides real-time dashboards, and allows managers to submit reports from their phones without installing any software on the phones. Which combination of Microsoft Power Platform tools should the company use?
⚠ Common exam trap
Watch out — candidates often think a single tool can cover all requirements, but the question explicitly demands three distinct capabilities (mobile input, automation, dashboards) that map to three separate Power Platform components, not one or two.

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 Apps, Power Automate, and Power BI
The scenario requires a combination of Power Apps (for mobile-friendly report submission without installing software), Power Automate (to automate data entry into the central system), and Power BI (to provide real-time dashboards). Power Apps alone cannot automate data entry or provide dashboards; Power Automate alone cannot provide a mobile input interface or dashboards; Power BI alone cannot capture data or automate workflows. Only the trio covers all requirements: mobile input, automated processing, and real-time visualization.
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 Automate only
Why it's wrong here
Power Automate moves and triggers data between services but offers no user interface for managers to submit counts and no dashboards, so the paper-to-system gap persists. It is tempting because automation of data entry is the stated pain point, and it would be correct if a capture app and reporting layer already existed.
- ✗
Power Apps only
Why it's wrong here
Power Apps delivers the mobile browser-based entry form, but it provides no automated flow to write submissions into the central system and no real-time dashboards for replenishment decisions. It is tempting because it satisfies the no-install phone requirement, and it would be the right sole tool if only data capture were needed.
- ✓
Power Apps, Power Automate, and Power BI
Why this is correct
Power Apps delivers a phone browser-based canvas app requiring no installation, Power Automate replaces manual entry by writing counts into the central system, and Power BI supplies real-time dashboards. Together they satisfy automation, dashboards and no-install mobile submission.
- ✗
Power BI only
Why it's wrong here
Power BI renders dashboards and reports but cannot capture phone submissions or automate the entry of stock counts into the central system, leaving the paper-and-email process intact. It is tempting because real-time dashboards are an explicit requirement, and Power BI alone would suffice if the data were already flowing into a source it can query.
