Exam AD0-E902 Topic 2 Question 1 Discussion

* Understanding Instant and Polling Triggers:
* Instant Triggers:
* Rely on webhooks to receive real-time data from a third-party system.
* The external system sends a notification (webhook) to Fusion whenever an event occurs, triggering the scenario immediately.
* Polling Triggers:
* Regularly check (poll) the third-party system for new or updated records at scheduled intervals.
* These are slower because they involve repeated API requests.
* Why Option B is Correct:
* Speed and Efficiency:
* Instant triggers process data faster because they act immediately upon receiving a webhook. Polling triggers, on the other hand, may take time depending on the polling frequency and can result in unnecessary delays.
* Reduced Load on Systems:
* Instant triggers generate fewer API calls than polling triggers, which continuously check for new records even if no changes have occurred.
* Best Practice: Use instant triggers whenever supported by the third-party system to ensure faster and more efficient scenario execution.
* Why the Other Options are Incorrect:
* Option A ("Instant triggers store received webhooks in a queue"):
* Webhooks do not store data in a queue; they simply notify Fusion of events in real-time.
Polling triggers also do not store records but remember the last processed record.
* Option C ("A user must set up a webhook in Fusion"):
* Instant triggers require setting up webhooks in the external system, not in Fusion. Fusion provides the webhook endpoint, but the user must configure the source system to send data.
* Option D ("Only polling triggers can be set to run on a schedule"):
* This is incorrect because instant triggers do not rely on schedules; they operate in real-time.
Polling triggers, however, run on schedules and are used when instant triggers are unavailable.

* Workfront Community: Differences Between Instant and Polling Triggers Instant triggers are the preferred option when available, as they provide real-time data processing with greater speed and efficiency than polling triggers.
