PL-900 Trigger Practice Question
Which THREE components are part of a Power Automate cloud flow?
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
✓
Action
A Power Automate cloud flow is built from three core components: a Trigger (option E), which defines the event that starts the flow (such as a new email, a scheduled recurrence, or an HTTP request); an Action (option A), which is each step that performs work after the trigger (for example, sending a Teams message, creating a SharePoint item, or calling a connector operation); and a Connector (option B), which is the API wrapper that exposes the underlying service's triggers and actions to the flow. These three elements are exactly what the flow designer composes into the definition that runs in the Power Automate service. Business process flow (option C) is a different Power Platform feature used in Dynamics 365/model-driven apps for guiding users through stages, not a component of a cloud flow, and Power Apps (option D) is a separate app-building service rather than a building block inside a flow.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Action
Why this is correct
An action is a discrete operation performed after the trigger, such as creating a record or sending a message. It is a core building block of a cloud flow definition, satisfying the question's requirement for a flow component.
- ✓
Connector
Why this is correct
A connector provides the prebuilt interface through which a flow calls an external service's operations, such as SharePoint or Outlook. It is a core building block of a cloud flow definition, satisfying the question's requirement for a flow component.
- ✗
Business process flow
Why it's wrong here
Business process flow is a separate Power Platform component for guiding users through defined stages; it is not part of a cloud flow's structure. It is tempting because both appear in the same maker portal, but a cloud flow comprises a trigger and one or more actions.
- ✗
Power Apps
Why it's wrong here
Power Apps is a separate low-code app-building service, not a component of a cloud flow; a flow comprises a trigger, actions and connectors. It is tempting because Power Apps and Power Automate are both Power Platform services that share connectors and can call each other, so it would be the right answer if the question asked which service embeds a flow.
- ✓
Trigger
Why this is correct
A trigger is the event that starts a cloud flow, such as a new email or a scheduled recurrence. It is a core building block of a cloud flow definition, satisfying the question's requirement for a flow component.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which THREE components are part of a Power Automate cloud flow? (Select THREE.)
easy- A.Environment
- ✓ B.Condition
- C.Connector
- ✓ D.Action
- ✓ E.Trigger
Why B: In Power Automate, every cloud flow is built from a trigger (E), which is the event that starts the flow (for example, 'When a new email arrives' or a manual button press), and one or more actions (D), which are the operations the flow performs after it is triggered, such as sending a message or creating a record. A condition (B) is also a core flow component: it is a control/decision construct that evaluates an expression and branches the run into 'If yes' and 'If no' paths, directing which actions execute. These three — trigger, action, and condition — are the building blocks that define a flow's logic. An environment (A) is not a flow component but the container/administrative boundary (with its own Dataverse, connections, and permissions) in which flows are created and stored. A connector (C) is likewise not a flow component itself; it is the API wrapper or service interface (such as the SharePoint or Outlook connector) that exposes the triggers and actions a flow can use.
