Quick Answer
The answer is that Screen2 does not exist in the app. When a button with the Navigate function does nothing, the most likely cause is that the target screen name is missing or misspelled, because the Navigate function fails silently when it cannot find the specified screen. This tests your understanding of how Power Apps handles screen navigation and formula evaluation—the app does not throw an error for a nonexistent screen; it simply ignores the command. On the PL-900 exam, this is a classic trap: candidates often suspect publishing status or permissions, but navigation between screens is purely formula-driven and works immediately in the editor. A common memory tip is to think of Navigate like a GPS—if the destination address (screen name) is wrong, the car just sits still. Always double-check that every screen name in your Navigate calls matches exactly, including capitalization and spaces.
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 user reports that a Power App button does nothing when clicked. The button's OnSelect property contains: Navigate(Screen2). What is the most likely cause?

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.
The formula is missing parentheses
Why wrong: The formula has proper parentheses
The user lacks permission to navigate to Screen2
Why wrong: No permissions are required for screen navigation
The app is not published
Why wrong: Unpublished apps can still run in preview; navigation works
Screen2 does not exist in the app
Navigate to a non-existent screen causes failure
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Screen2 does not exist in the app
Option B is correct because if Screen2 does not exist, the Navigate function fails silently. Option A is wrong because the app does not need to be published to test navigation. Option C is wrong because the formula is correct if Screen2 exists. Option D is wrong because permissions do not affect navigation between screens.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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

Real-world example
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.
