What is the purpose of a Poll scope in a Mule flow?

• A. To periodically poll a source for work
• B. To route messages to an endpoint
• C. To transform payload data
• D. To manage security context

Answer: (A)

Poll scope is used to periodically check a configured source for new work and hand off each found item to the inner flow for processing. It relies on a scheduler to trigger the poll at the configured interval, so you can process data from sources that generate work intermittently—like new files in a directory, rows added to a database, or messages in a queue. This scope is specifically about fetching work over time, not about routing messages, transforming payloads, or managing security. Routing would be done by a Router or flow logic, transformation happens with a transformer/DataWeave step, and security context is handled by security configurations, not the poll mechanism.
