- A
Add a Text input control for manual barcode entry, use Power Automate flows to fetch product details, enable offline by storing data locally in collections, and deploy by sending a deep link.
Why wrong: Manual entry defeats the scanning requirement; flows do not work offline.
- B
Use a Power Fx formula with the Camera control to decode barcodes, enable offline data in SharePoint lists, add a Copilot chat box, and deploy via Microsoft Intune as a required app.
Why wrong: Power Fx formula for barcode decoding is not a standard approach and lacks reliability.
- C
Add the Barcode scanner control to the canvas app, enable offline mode in app settings, integrate Copilot using the Copilot control, and deploy the app by sharing it via email link.
Why wrong: Email link does not enforce automatic installation; staff must manually install the app.
- D
Add the Barcode scanner control, configure the app for offline use with sync, integrate Copilot using the AI Builder 'Ask a question' component, and deploy the app via Power Apps mobile app with a managed solution and installation policy.
All requirements are met: barcode scanning, offline sync, Copilot, and automatic deployment.
Quick Answer
The correct answer is to add the Barcode scanner control, configure the app for offline use with sync, integrate Copilot using the AI Builder 'Ask a question' component, and deploy via Power Apps mobile app with a managed solution and installation policy. This approach works because the Barcode scanner control natively uses the device camera for scanning, while Power Apps mobile app provides built-in offline sync capabilities that cache data locally and reconcile changes when connectivity returns. The Copilot integration uses the AI Builder 'Ask a question' component to enable natural language queries against your data, and deploying as a managed solution with an installation policy ensures automatic, no-touch distribution to all warehouse staff. On the PL-900 exam, this question tests your ability to combine multiple platform features—scanning, offline, AI, and deployment—into a single solution, a common scenario in the "Describe building Power Apps" domain. A frequent trap is choosing Power Automate flows for scanning, which fail in real-time offline scenarios. Memory tip: think "Scan, Sync, Ask, Ship"—the four pillars of this solution.
PL-900 Demonstrate the capabilities of Power Apps Practice Question
This PL-900 practice question tests your understanding of demonstrate the capabilities of power apps. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 manufacturing company uses Power Apps to manage inventory tracking. The current app is a canvas app connected to a SharePoint list. The operations team needs to add a new feature that allows warehouse staff to scan barcodes using a mobile device camera to look up product details. Additionally, the app must work offline in areas with no internet connectivity and sync data when connectivity is restored. The app should also incorporate a Copilot assistant to help staff quickly find product information using natural language queries. The IT department requires that the app be deployed to all warehouse staff without requiring manual installation. Which approach should you take to meet all requirements?
Answer choices
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
Add the Barcode scanner control, configure the app for offline use with sync, integrate Copilot using the AI Builder 'Ask a question' component, and deploy the app via Power Apps mobile app with a managed solution and installation policy.
Option D is correct because it combines the Barcode scanner control for camera-based scanning, offline capabilities via Power Apps mobile app with offline sync, Copilot in Power Apps for natural language queries, and automatic deployment using a managed solution and Power Apps mobile app installation policy. Option A fails to address offline and Copilot requirements. Option B uses Power Fx formula, which is not a native barcode scanning method. Option C uses Power Automate flows, which are not suitable for real-time offline scanning.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Why this is correct
All requirements are met: barcode scanning, offline sync, Copilot, and automatic deployment.
Related concept
OSPF neighbours must agree on key parameters.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
How this comes up in practice
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. OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related PL-900 OSPF questions on adjacency and route selection.
