Quick Answer
The answer is a canvas app. This is the correct choice because canvas apps provide complete control over the user interface layout, allowing you to design a custom mobile experience for field technicians, and they natively connect to hundreds of data sources, including an existing SQL database, without requiring a pre-built data model. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your ability to distinguish between app types based on user needs and data source requirements; a common trap is confusing the flexible, pixel-perfect canvas app with the rigid, form-driven model-driven app, which is designed for complex business processes and not ideal for a simple mobile logging tool. To remember, think of a canvas as a blank painting surface where you can freely arrange buttons and fields, while a model-driven app is like a pre-built form you must fill in.
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 wants to create a mobile app for field technicians to log service calls. The app will connect to an existing SQL database. Which type of Power App should they build?
Power Automate flow
Why wrong: Power Automate is for workflow automation, not building user interfaces.
Model-driven app
Why wrong: Model-driven apps are built on Dataverse and are form-heavy, not ideal for custom mobile layouts.
Power Pages
Why wrong: Power Pages is for creating external websites, not mobile apps.
Canvas app
Canvas apps provide full control over UI and can connect to SQL databases, perfect for mobile field apps.
Answer choices

Correct answer & explanation
Canvas app
Option C is correct because canvas apps allow custom layout and connectivity to many data sources, ideal for mobile scenarios. Option A is wrong because model-driven apps are form-centric and designed for complex business processes. Option B is wrong because Power Pages is for external-facing websites. Option D is wrong because Power Automate is for automation, not app building.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
