Quick Answer
The answer is a model-driven app. This is the correct choice because it is built on Dataverse, which provides the relational data model needed to link patients to their visit records, and it natively includes a timeline control that automatically aggregates and displays those records in chronological order for each patient. On the PL-900 exam, this question tests your understanding of when to choose a model-driven app over a canvas app or portal—the key distinction is that model-driven apps excel at complex, data-centric scenarios with built-in business logic and timeline components, while canvas apps are better for custom layouts or simple forms. A common trap is to select a canvas app because it seems more flexible, but remember that the timeline feature is a native model-driven component, not a canvas one. Memory tip: “Model-driven for the timeline—canvas for the canvas.”

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 healthcare organization needs a Power Apps app to track patient visit data. The data must be stored in Microsoft Dataverse, and the app should automatically generate a timeline of visits for each patient. Which app type is most suitable?
Portal
Why wrong: Portals are not suitable for internal tracking.
Model-driven app
Model-driven apps provide built-in timeline and Dataverse integration.
Power Automate
Why wrong: Power Automate is a separate product.
Canvas app
Why wrong: Canvas apps require custom components for timeline.

Correct answer & explanation
Model-driven app
A model-driven app is the most suitable choice because it is designed for complex, data-centric business applications that require rich relational data modeling, automated business logic, and built-in timeline controls. Dataverse provides the underlying relational storage, and model-driven apps natively support timeline components that automatically aggregate and display patient visit records in chronological order without custom development.
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 not suitable for internal tracking.
Model-driven app
Why this is correct
Model-driven apps provide built-in timeline and Dataverse integration.

Power Automate
Why it's wrong here
Power Automate is a separate product.
Canvas app
Why it's wrong here
Canvas apps require custom components for timeline.
Common exam traps
The trap here is that candidates often choose Canvas app because they think custom UI is needed for a timeline, but model-driven apps already include a native timeline component that automatically binds to Dataverse relationships, making it the correct choice for structured data tracking.
Detailed technical explanation
Model-driven apps leverage Dataverse’s relational model, where a Patient entity and a Visit entity can be linked via a lookup relationship. The timeline control automatically queries related activity records (e.g., visits, notes, appointments) based on the ‘Regarding’ lookup field and displays them in reverse chronological order, respecting security roles and field-level permissions. This eliminates the need for custom code or complex Power Fx formulas to achieve the same result.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
