Quick Answer
The answer is a Canvas app. This is the correct choice because Canvas apps support offline capability through the Power Apps mobile player, which caches data locally on the device and automatically syncs changes when connectivity is restored, making them ideal for field service technicians who need to view and update work orders without constant internet access. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your understanding of Power App types and their specific features, often appearing as a scenario where mobile, offline-first requirements are described. A common trap is choosing Model-driven apps, which are primarily online and rely on Dataverse connectivity, whereas Canvas apps offer explicit offline sync logic and custom UI tailored to mobile scenarios. Remember the memory tip: “Canvas caches, Model needs modems” — if the task demands offline work, think Canvas.
This PL-900 practice question tests your understanding of demonstrate the capabilities of power apps. 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 needs to create a mobile app for field service technicians to view and update work orders. The app should work offline and sync when connected. Which type of Power App should they build?
Canvas app
Canvas apps offer flexible design and can be built with offline capabilities.
SharePoint list app
Why wrong: SharePoint lists are data sources, not a type of Power App.
Power Automate flow
Why wrong: Power Automate is for workflows, not standalone apps.
Model-driven app
Why wrong: Model-driven apps are more form-focused and require connectivity.

Correct answer & explanation
Canvas app
A Canvas app is the correct choice because it supports offline capability via the Power Apps mobile player, which can cache data locally and sync changes when connectivity is restored. This is ideal for field service technicians who need to view and update work orders without constant internet access, as Canvas apps allow custom UI tailored to mobile scenarios and can leverage the Offline-first pattern with explicit sync logic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

SharePoint list app
Why it's wrong here
SharePoint lists are data sources, not a type of Power App.
Power Automate flow
Why it's wrong here
Power Automate is for workflows, not standalone apps.
Model-driven app
Why it's wrong here
Model-driven apps are more form-focused and require connectivity.
Common exam traps
The trap here is that candidates often confuse Model-driven apps with offline support because they think Dataverse's offline profiles are equivalent to Canvas apps' built-in offline, but Model-driven apps require complex configuration and are less suited for custom mobile UIs, while Canvas apps are the straightforward choice for offline-first mobile scenarios.
Detailed technical explanation
Under the hood, Canvas apps use the Power Apps mobile player's offline capability, which leverages a local SQLite database to store data from connectors like Dataverse or SharePoint. The sync process uses conflict detection and retry logic, and developers must explicitly enable 'Offline' in app settings and configure data sources for offline use. In a real-world scenario, a technician might update a work order status while in a basement with no signal; the app queues the change locally and syncs automatically when the device reconnects, using the 'Sync' function or automatic refresh.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company wants to create a mobile app for field service technicians to log work orders. The app must use a SharePoint list as the data source and include offline capability. Which type of Power App should they build?
easyWhy D: A canvas app allows custom layout and offline support via Power Apps mobile. Model-driven apps (B) are primarily for data management and require online connectivity. Power Pages (C) is for external websites. Power Automate (D) is for workflow automation.
Variation 2. A company wants to create a mobile app for field technicians to view and update work orders. The work orders are stored in a SharePoint list. Technicians need to filter work orders by status and take photos of completed work, attaching them to the work order. Which type of Power App should you recommend? A) Model-driven app B) Canvas app C) Power Pages website D) Power Automate flow
easyWhy A: Option B is correct because canvas apps provide flexible UI design, support for camera control, and easy connection to SharePoint. Option A: Model-driven apps are good for complex data but have limited custom UI for camera. Option C: Power Pages is for external websites, not mobile app. Option D: Power Automate is for automation, not app building.
