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 company has a model-driven app with a custom table 'Issue' that has a choice column 'Status' with values: New, In Progress, Resolved, Closed. The app uses a business rule to set 'Resolved By' (lookup to User) when status changes to Resolved. Users report that the 'Resolved By' field is not being populated. 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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The business rule is scoped to the form but the status change happens via a quick create form.
Business rules in model-driven apps can be scoped to either the entity (all forms) or a specific form. If the rule is scoped to a particular form (e.g., the main form) but the status change occurs via a quick create form, the rule will not trigger. This is the most likely cause because users report the field is not populated, indicating the rule is not firing in the context where the status is being changed.
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 'Resolved By' lookup column is not added to the form.
Why it's wrong here
The column must be on the form for the rule to set it, but the rule can set it even if hidden.
✗
The 'Resolved By' column is required and users don't fill it.
Why it's wrong here
The rule should populate it automatically.
✓
The business rule is scoped to the form but the status change happens via a quick create form.
Why this is correct
Business rules only apply to the form they are scoped to.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
The business rule is deactivated.
Why it's wrong here
If deactivated, it wouldn't work at all.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a business rule always applies to all forms of an entity, overlooking the scope setting that can restrict it to a specific form type, such as the main form versus a quick create form.
Detailed technical explanation
How to think about this question
Business rules in Power Apps (model-driven apps) have a scope property: 'All Forms' applies the rule to every form of the entity, while 'Specific Form' restricts it to that form only. Quick create forms are separate form types and are not considered 'main' forms; thus, a rule scoped to the main form will not execute on a quick create form. This is a common misconfiguration when developers assume the rule applies globally without explicitly setting the scope to 'All Forms'.

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 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.
