- A
Implement a timer control to delay scanning between items.
Why wrong: This would only mask the issue and degrade user experience.
- B
Migrate the SharePoint list to an on-premises SQL Server database.
Why wrong: On-premises SQL would introduce latency and maintenance overhead.
- C
Optimize the Power Apps by enabling delegation for the SharePoint connector.
Delegation allows queries to be processed server-side, reducing data transfer.
- D
Replace SharePoint with Microsoft Dataverse for better performance.
Why wrong: Dataverse may require additional licensing and migration effort.

PL-900 Practice Question: Describe complementary Microsoft Power Platform solutions
This PL-900 practice question tests your understanding of describe complementary microsoft power platform solutions. 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 manufacturing company uses Microsoft Power Platform to manage its inventory. They have a Power Apps app that allows warehouse staff to scan items and update quantities in a SharePoint list. Recently, the app has been slow to load and occasionally times out when scanning multiple items in quick succession. The IT team suspects the issue is related to the data source connection. They want to improve performance without changing the user interface. The company has a Microsoft 365 E3 subscription and all data resides in SharePoint Online. What should the IT team do first?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Optimize the Power Apps by enabling delegation for the SharePoint connector.
Option C is correct because enabling delegation for the SharePoint connector allows Power Apps to offload filtering and sorting operations to SharePoint Online, rather than retrieving all rows to the client. This reduces the amount of data transferred over the network, which directly addresses the slow load and timeout issues when scanning multiple items in quick succession, without changing the user interface.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'optimizing performance' with 'changing the data source' (Option B or D) or 'adding client-side delays' (Option A), rather than recognizing that the most immediate and non-disruptive fix is to enable delegation on the existing SharePoint connector.
Detailed technical explanation
How to think about this question
Delegation in Power Apps works by translating app formulas (e.g., Filter, SortByColumns) into server-side queries using the SharePoint REST API, which supports OData query operators like $filter and $orderby. Without delegation, Power Apps must pull all list items (up to the non-delegable limit of 500 or 2000 rows) to the client for processing, causing performance degradation. Enabling delegation ensures that only the relevant subset of data is transferred, reducing network payload and improving responsiveness under rapid scanning conditions.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- 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 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.
