PL-900 Demonstrate the capabilities of Power Apps Practice Question
A supply chain analyst uses a Power Apps canvas app to scan barcodes in a warehouse where network connectivity is intermittent. The app must store scanned records locally and upload them later when connectivity returns. Which Power Apps capability should the analyst use?
⚠ Common exam trap
The trap here is assuming any cloud-connected feature such as a flow or a Dataverse table provides offline queuing, when only device-local storage functions persist data without a network.

Correct answer & explanation
✓
SaveData and LoadData functions
Canvas apps support offline use through device-local storage. The SaveData function serializes a collection to the local device, and LoadData reads it back. A warehouse app can collect scans into a collection, persist with SaveData, and later LoadData and write to the data source when the network is available. This directly satisfies the intermittent-connectivity requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SaveData and LoadData functions
Why this is correct
SaveData writes a collection to local storage on the device, and LoadData restores it. In an intermittent-network warehouse, the app can capture scans into a collection, call SaveData, and later LoadData and submit when connectivity returns. This is the documented offline pattern for canvas apps and works without a network connection.
- ✗
A Power Automate instant cloud flow triggered by the app
Why it's wrong here
An instant cloud flow runs in the cloud and requires the app to reach the Power Automate service at trigger time. During an outage the trigger cannot be sent, so scans would not be queued. It also does not provide device-local persistence, so it fails the core offline requirement.
- ✗
Delegation with a SharePoint list
Why it's wrong here
Delegation determines which query operations are processed server-side versus limited to the first 500 or 2000 records. It is about query correctness and scale, not offline storage. A SharePoint list still requires a live connection, so intermittent connectivity would still block saving scans in the warehouse.
- ✗
Concurrent function with a Dataverse table
Why it's wrong here
The Concurrent function only runs multiple formulas in parallel to improve performance; it does not persist data locally. If the warehouse loses connectivity, a Dataverse write fails regardless of Concurrent, so scanned records would be lost. It addresses speed, not offline durability, which is the requirement here.
