Quick Answer
The answer is the "When a file is created" trigger. This trigger is specifically designed to initiate a Power Automate cloud flow the moment a new file is added to a SharePoint document library, making it the correct choice for sending an automatic email notification. It listens exclusively for creation events, not modifications or deletions, which ensures your flow runs only when a brand-new file appears. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your understanding of SharePoint triggers and their distinct event types—a common trap is confusing "created" with "created or modified," which would fire on updates as well. To remember, think of the trigger as a door that only opens for new arrivals: if the file already existed, it won't knock.
This PL-900 practice question tests your understanding of demonstrate the capabilities of power automate. 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.

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 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.
