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 retail company uses Power Apps to build a mobile app for store managers to approve discount requests. The app must work offline and sync when connected. Which type of app should the developer choose?
Portal
Why wrong: Portals are for external users and require connectivity.
Model-driven app
Why wrong: Model-driven apps are not designed for offline use.
Canvas app
Canvas apps can be built to work offline with the Power Apps mobile player.
Power Automate
Why wrong: Power Automate is a workflow tool, not an app type.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Canvas app
Canvas apps are the correct choice because they support offline capability by leveraging the Power Apps offline sync feature, which allows data to be cached locally on the device and synchronized with the data source (e.g., Dataverse or SharePoint) when connectivity is restored. This makes them ideal for mobile scenarios like store managers approving discount requests in areas with intermittent connectivity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Portal
Why it's wrong here
Portals are for external users and require connectivity.
Model-driven app
Why it's wrong here
Model-driven apps are not designed for offline use.
Canvas app
Why this is correct
Canvas apps can be built to work offline with the Power Apps mobile player.

Power Automate
Why it's wrong here
Power Automate is a workflow tool, not an app type.
Common exam traps
The trap here is that candidates often confuse Model-driven apps with offline capability because they see 'mobile' in the question, but Model-driven apps require a constant connection to Dataverse and do not offer built-in offline sync like Canvas apps do.
Detailed technical explanation
Canvas apps use the Power Apps mobile player to store data locally in a SQLite database on the device, enabling offline read and write operations. When connectivity is restored, the app automatically syncs changes using conflict detection and resolution strategies (e.g., last-writer-wins) defined in the data source. This is particularly useful in retail environments where store managers may need to approve discounts in basements or remote stockrooms without Wi-Fi.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
