Demonstrate the capabilities of Power Apps →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the target screen 'OrderDetailScreen' does not exist in the app. This is correct because the button's OnSelect property contains a Navigate function that references a specific screen name, and if that screen has not been added to the app, the function cannot find a destination, causing the button to appear unresponsive when tapped. On the PL-900 exam, this scenario tests your understanding of canvas app navigation and screen management, often appearing as a trap where learners assume the issue is with the data source or gallery configuration since the orders display correctly. A common memory tip is to remember that a button that does nothing usually points to a missing target, not a broken data connection—think "Navigate needs a destination."

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 developer creates a canvas app to display orders from Microsoft Dataverse. The app uses the gallery and data configuration shown in the exhibit. When the app runs, the gallery shows orders but the 'View Details' button does nothing when tapped. What is the most likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

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

✓

The target screen 'OrderDetailScreen' does not exist in the app

Option B is correct because the Navigate function in the button's OnSelect property references 'OrderDetailScreen', but if that screen does not exist in the app, the function cannot execute, causing the button to appear unresponsive. The gallery displays orders correctly, confirming the data source and Items property are functional, isolating the issue to the navigation target.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    The button's OnSelect property has a syntax error

    Why it's wrong here

    The exhibit shows the action as 'Navigate(OrderDetailScreen)', which is valid syntax.

  • ✓

    The target screen 'OrderDetailScreen' does not exist in the app

    Why this is correct

    The navigation action references a screen that is not defined.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The Dataverse connection requires user authentication

    Why it's wrong here

    If authentication failed, the gallery would not show data.

  • ✗

    The gallery's items property is misconfigured

    Why it's wrong here

    The gallery shows orders, so items property works.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates assume the button's OnSelect property must have a syntax error when it does nothing, but Power Apps silently fails on invalid screen references, making the missing screen the more subtle and likely cause.

Trap categories for this question

  • Command / output trap

    The exhibit shows the action as 'Navigate(OrderDetailScreen)', which is valid syntax.

Detailed technical explanation

How to think about this question

The Navigate function in Power Apps uses the screen name as a string argument; if the screen does not exist, the function silently fails without throwing an error in the app, making it a common oversight. Under the hood, Power Apps resolves screen references at runtime by matching the string to the Screen property of the app's screens collection, and a mismatch results in a no-op. In real-world scenarios, this often occurs when screens are renamed or deleted after the button's OnSelect is configured, or when copying controls between apps with different screen structures.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
