The answer is to apply a delegable filter on the data source to limit the records returned. This works because delegation pushes data processing to the source—like a large SharePoint list—so only the filtered subset is transferred over the network, drastically reducing load time. In the context of the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your understanding of delegation as a core performance strategy for canvas apps connecting to large data sources. A common trap is assuming that increasing the delegation limit (e.g., from 500 to 2000) solves the problem, but if the query itself isn’t delegable, the app still pulls all 10,000+ items locally. Remember the memory tip: “Delegate to eliminate, don’t escalate to compensate”—always ensure your filter, sort, and search functions are delegable to keep performance snappy.

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 user reports that a canvas app is loading slowly. The app connects to a large SharePoint list with over 10,000 items. Which change would most improve performance?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply a delegable filter on the data source to limit records returned.
Using a filter on the data source reduces the number of records retrieved, improving performance. Option A is wrong because adding more screens doesn't help. Option B is wrong because disabling offline doesn't affect loading speed. Option D is wrong because increasing delegation limit doesn't improve performance when the query is not delegable.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Increase the delegation limit to 10,000.
Why it's wrong here
Increasing delegation limit doesn't speed up loading; it only allows more records.
✓
Apply a delegable filter on the data source to limit records returned.
Why this is correct
Filtering at the data source reduces the data transferred and improves performance.

TExam Day Tips
→Underline the problem statement mentally.
→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.

Variation 1. A canvas app includes a gallery that shows a list of customers. The app loads slowly when the gallery displays more than 500 records. What is the best way to improve performance?
hard
A.Use a non-delegable query
B.Convert the app to a model-driven app
✓ C.Apply a filter to the gallery data source
D.Increase the gallery height
Why C: Option B is correct because using a filter to reduce the number of records loaded improves performance. Option A is wrong because increasing the gallery height does not affect data loading. Option C is wrong because delegable queries only work with certain data sources; for non-delegable sources, filtering is best. Option D is wrong because moving to a model-driven app is a redesign, not a simple fix.
