The answer is Azure Event Grid and Azure Logic Apps, as both services enable Power Automate to trigger flows from external systems by extending its native event-driven capabilities. Azure Event Grid uses a publish-subscribe model to route events from Azure services or custom sources in near real-time, while Azure Logic Apps provides pre-built connectors and enterprise integration features like HTTP requests and webhooks, allowing Power Automate to react to external triggers beyond its standard connectors. On the PL-900 exam, this question tests your understanding of how Power Automate integrates with broader Azure services for event-driven automation, often appearing as a scenario where a company needs to respond to external system events like file uploads or service alerts. A common trap is confusing Azure Logic Apps with Power Automate itself—remember that Logic Apps is the integration bridge, not the flow engine. Memory tip: think of Event Grid as the “event postman” and Logic Apps as the “integration translator” working together to extend Power Automate’s reach.
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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 company uses Microsoft Power Platform to automate business processes. They want to extend their solution by integrating with other Microsoft services. Which TWO services can be used together with Power Automate to trigger flows based on events from external systems?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Logic Apps
Azure Logic Apps is a cloud service that provides pre-built connectors and enterprise integration capabilities, allowing Power Automate to trigger flows based on events from external systems via HTTP requests, webhooks, or service bus messages. Azure Event Grid is a fully managed event routing service that uses a publish-subscribe model, enabling Power Automate to react to events from Azure services or custom sources in near real-time. Both services extend Power Automate's event-driven triggers beyond its native connectors.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Azure Event Grid allows event-driven triggers for Power Automate flows.
Related concept
Read the scenario before looking for a memorised answer.
✗
Power Virtual Agents
Why it's wrong here
Power Virtual Agents is a chatbot service, not an event trigger.
✗
Azure DevOps
Why it's wrong here
Azure DevOps is for CI/CD pipelines, not for triggering flows based on external events.
✗
Azure SQL Database
Why it's wrong here
Azure SQL Database is a data store; it does not directly trigger flows.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Azure Logic Apps as a standalone alternative to Power Automate rather than recognizing it as a complementary service that provides advanced event triggers, or they may incorrectly assume Azure SQL Database can natively trigger flows without an intermediary event service.
Detailed technical explanation
How to think about this question
Azure Event Grid uses HTTP-based webhook delivery with an SLA of 99.99% and supports custom topics for routing events from any source, while Azure Logic Apps can act as an event handler for Event Grid or directly expose an HTTP endpoint. In a real-world scenario, an external SaaS application can post events to an Event Grid custom topic, which then triggers a Power Automate flow via a Logic Apps connector, enabling decoupled, scalable integration without polling.

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 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.
