PL-900 Practice Question: Describe the business value of Microsoft Power Platform
This PL-900 practice question tests your understanding of describe the business value of microsoft power platform. 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.
Your organization has a Power Apps app that uses the Microsoft Dataverse connector. Users report that the app loads slowly. You review the app and find that it loads all records from a large table (over 500,000 rows) into a gallery. What is the best action to improve performance?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Modify the gallery's Items property to use a delegable filter, such as Filter(Table, Condition).
Option B is correct because modifying the gallery's Items property to use a delegable filter (e.g., Filter(Table, Condition)) ensures that the query is processed server-side by Microsoft Dataverse, retrieving only the subset of records that match the condition. This avoids loading all 500,000+ rows into the client app, which is the root cause of the slow performance. Delegation allows Power Apps to offload data processing to the data source, significantly reducing network payload and client memory usage.
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.
✗
Increase the data row limit in the app settings.
Why it's wrong here
Increasing limit would worsen performance by loading more data.
✓
Modify the gallery's Items property to use a delegable filter, such as Filter(Table, Condition).
Why this is correct
Delegation filters are processed server-side, reducing data load.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Clear the app cache on the client devices.
Why it's wrong here
Caching helps with subsequent loads, not initial load speed.
✗
Reduce the delegation limit in the environment settings.
Why it's wrong here
Reducing limit would not help; delegation must be used.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse client-side caching or row limits with the core delegation concept, mistakenly believing that increasing limits or clearing caches solves performance issues, when the real solution is to ensure queries are processed on the server via delegable filters.
Detailed technical explanation
How to think about this question
Under the hood, Power Apps delegation relies on the connector's ability to translate canvas app functions (like Filter, SortByColumns) into server-side queries (e.g., OData $filter parameters). For Microsoft Dataverse, the default non-delegable limit is 500 records; without delegation, the app downloads all matching rows up to the data row limit (default 500) and then applies filters client-side, which is inefficient for large tables. A real-world scenario is a sales dashboard gallery that must show only active accounts; using a delegable Filter on the 'Status' column ensures only active records are transferred, while a non-delegable filter would pull all 500,000+ rows and filter locally, causing timeouts and poor UX.

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
