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.
You are a Power Platform administrator for a large multinational company that uses Microsoft Power Platform to manage its sales operations. The company has a Power App for sales representatives to log customer meetings and a Power Automate flow that sends a summary email to the sales manager after each meeting is logged. Recently, sales representatives have reported that the app is slow to load and sometimes times out. The IT team has checked network connectivity and server performance and found no issues. The app uses Dataverse as its data source and includes several lookup fields to related tables. The Power Automate flow runs immediately after a meeting is created and queries additional data from the Dataverse. You suspect the issue is related to the flow's trigger and subsequent queries. What course of action should you take to improve performance?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Modify the flow to run on a schedule instead of immediately upon record creation
Option A is correct because the performance issue is likely caused by the Power Automate flow's trigger running synchronously or near-synchronously upon record creation, which can block the app's response or cause timeouts if the flow queries additional Dataverse data. By modifying the flow to run on a schedule (e.g., every 5 minutes), you decouple the heavy query operations from the real-time app interaction, reducing the load on the app's session and preventing timeouts.
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.
✓
Modify the flow to run on a schedule instead of immediately upon record creation
Why this is correct
Running on a schedule reduces the immediate load on the Dataverse and improves app responsiveness.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Disable the Power Automate flow and manually send summary emails
Why it's wrong here
Disabling the flow stops the emails, but does not address the app slowness caused by the flow.
✗
Implement caching in the Power App to store lookup data locally
Why it's wrong here
Caching lookup data can help, but the main issue is the flow's real-time queries.
✗
Increase the timeout duration of the Power Automate flow to allow more time for queries
Why it's wrong here
Increasing timeout does not reduce load; it only allows longer execution.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse client-side app performance issues (like lookup caching) with server-side flow execution delays, and they incorrectly assume that increasing timeouts or disabling automation will solve the problem, rather than recognizing that decoupling the flow from the real-time trigger is the proper architectural fix.
Detailed technical explanation
How to think about this question
Power Automate flows with an 'immediately' trigger (e.g., 'When a row is added, modified, or deleted') run in the same transaction scope as the Dataverse operation, which can hold locks and delay the app's response until the flow completes. Scheduling the flow (e.g., using 'Recurrence' trigger) moves the queries to a separate background process, allowing the app to return control to the user faster. In high-volume scenarios, this also reduces contention on Dataverse tables and improves overall throughput.
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.
