PL-900 Automated trigger Practice Question
You create a Power Automate flow that runs when a new tweet matches a keyword. What type of trigger does this use?
⚠ Common exam trap
PL-900 often tests the distinction between automated (event-driven) and scheduled (recurrence) triggers, so candidates must recognize that 'when a new tweet matches a keyword' is event-driven, not timer-based.

Correct answer & explanation
✓
Automated trigger
An automated trigger in Power Automate fires in response to an event, such as a new tweet matching a keyword, without any user interaction. The Twitter/X connector provides a 'When a new tweet matching a keyword is posted' trigger, which is classified as automated because it is event-driven. This is distinct from scheduled or manual triggers, which require a timer or explicit user action.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Recurrence trigger
Why it's wrong here
A recurrence trigger fires on a fixed time interval, so it cannot react to a matching tweet as it is posted. It tempts because recurrence is the standard choice for polling or scheduled batch runs, and would be correct if the flow needed to check for tweets every hour.
- ✗
Manual trigger
Why it's wrong here
A manual trigger requires a user to start the flow, so it cannot fire automatically when a tweet matches the keyword. It tempts because manual triggers suit on-demand flows such as button-triggered mobile actions, and would be correct if a person chose when to run it.
- ✓
Automated trigger
Why this is correct
An Automated trigger fires automatically when the external event occurs, here a new tweet matching the keyword, satisfying the scenario's requirement. It requires no manual initiation, unlike Instant triggers, and is event-driven rather than recurrence-based like Scheduled triggers.
- ✗
Scheduled trigger
Why it's wrong here
A scheduled trigger runs at defined times rather than responding to each matching tweet as it appears. It tempts because scheduled triggers are the standard mechanism for recurring timed jobs, and would be correct if the flow needed to poll Twitter on a set cadence instead of reacting instantly.
