Quick Answer
The correct first step is to redesign the app to use delegation and reduce data requests. This directly addresses the performance bottleneck because when a canvas app connects to Dataverse without delegation, it retrieves all records locally before filtering, which overwhelms the device and network under high concurrency. By applying delegation, the filtering logic is pushed to the server, so only the necessary data is transferred, drastically reducing load times. On the Microsoft Power Platform Fundamentals PL-900 exam, this scenario tests your understanding of canvas app data source limits and the delegation concept—a common trap is assuming bandwidth or app type is the root cause, but inefficient queries are usually the culprit. Remember the memory tip: “Delegate to accelerate”—if your app feels slow, check whether your filters are delegable to the server first.
This PL-900 practice question tests your understanding of describe the business value of microsoft power platform. 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 large retail chain uses Power Platform to manage store operations. They have 500 stores, each with a tablet running a Power Apps canvas app for inventory management. The app connects to Dataverse. Recently, store managers reported that the app is slow during peak hours. The IT team suspects that the issue is due to the number of concurrent users and the design of the app. They need to improve performance without rewriting the app. What should they do first?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Migrate the app to a model-driven app
Why wrong: Migration is a major rewrite and may not be faster.
Replace the app with a Power BI dashboard
Why wrong: Power BI is not for inventory management transactions.
Increase the network bandwidth at each store
Why wrong: Network might not be the bottleneck.
Redesign the app to use delegation and reduce data requests
Delegation offloads processing to the data source, improving performance.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Redesign the app to use delegation and reduce data requests
Reducing the number of data requests by using delegation and filtering can significantly improve performance. Option B is incorrect because moving to model-driven app is not a simple fix. Option C is incorrect because increasing network bandwidth may not help if the app is making inefficient queries. Option D is incorrect because Power BI is not the issue.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
