Exam PL-600 topic 3 question 35 discussion

Why the other options are incorrect: A. Microsoft Power Apps API Request limit: Applies to Power Apps usage, not Power Automate flows. B. User entitlement limit: These are broader limits tied to licensing, but the issue here is short-term throttling, not entitlement caps. C. Microsoft Dataverse storage capacity limit: Affects data storage, not API call volume or flow execution. D. Microsoft Power Automate API Request limit: This is a general term, but the specific issue here is service protection throttling, which is more granular and time-based.

E - "is often delayed" but eventually executed - waits for the retry

"the higher API transaction volumes is as a result of the sales promotions"... to prevent excessive requests to the service, the Service protection API Limit acts as a mechanism causing the flow to pause temporarily if it hits the limit, often returning a "429 Too Many Requests" error and instructing the flow to wait before retrying

Microsoft Power Automate API Request limit pertains to the number of requests that can be made to the Power Automate service, and it is typically based on the license type or service plan. In this case, since the flow is being run under a service account that experienced a high volume of API transactions due to a sales promotion, it's likely that the flow is exceeding the allowable API request limit, causing delays or failures.
