The correct answer is a model-driven Power App configured for offline use. This is because model-driven apps are built on Microsoft Dataverse and natively integrate with the Dynamics 365 offline sync engine, which pre-caches customer records and work orders on the mobile device. When a field service technician loses connectivity, they can still view and update data locally; once the device reconnects, all changes are automatically synchronized back to Dataverse, ensuring data consistency. On the PL-900 exam, this scenario tests your understanding of how Power Apps handles mobile offline scenarios, often contrasting model-driven apps (which have built-in offline sync) with canvas apps (which require custom offline logic). A common trap is choosing a canvas app or assuming all Power Apps work offline by default. Memory tip: think “model-driven = mobile-ready offline” because the model (Dataverse) handles the sync engine for you.

Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to enable its field service technicians to access customer records and update work orders from their mobile devices offline. Which Power Platform solution should they implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Power Apps (model-driven) configured for offline use
Model-driven Power Apps natively support offline capabilities through the Dynamics 365 offline sync engine, which allows field service technicians to access customer records and update work orders without connectivity. When the device reconnects, changes are automatically synchronized with the Dataverse, ensuring data consistency. This makes it the correct choice for mobile offline scenarios.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 Pages website accessible from mobile browsers
Why it's wrong here
Power Pages is for external-facing websites, not for offline mobile access.
✓
Power Apps (model-driven) configured for offline use
Why this is correct
Model-driven Power Apps can be used offline, enabling technicians to view and edit data on their mobile devices.
Related concept
Read the scenario before looking for a memorised answer.
✗
Power BI dashboards embedded in a mobile app
Why it's wrong here
Power BI is for reporting, not for transactional data entry.
✗
Power Automate flows to sync data periodically
Why it's wrong here
Power Automate does not provide a mobile app interface for technicians to interact with records.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'offline access' with 'periodic sync' (Option D) or 'mobile browser access' (Option A), not realizing that only model-driven Power Apps provide a native offline runtime with full CRUD capabilities on mobile devices.
Detailed technical explanation
How to think about this question
Model-driven Power Apps leverage the Dynamics 365 offline profile, which uses client-side SQLite databases on mobile devices to cache entity data and metadata. When offline, changes are stored in a local change tracking table and replayed via the Dataverse Web API upon reconnection, handling conflicts with a 'last writer wins' strategy by default. This architecture ensures that field service technicians can continue working even in remote locations with intermittent connectivity.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
