Question 96

An organization is designing a Mule application to periodically poll an SFTP location for new files containing sales order records and then process those sales orders. Each sales order must be processed exactly once.

To support this requirement, the Mule application must identify and filter duplicate sales orders on the basis of a unique ID contained in each sales order record and then only send the new sales orders to the downstream system.

What is the most idiomatic (used for its intended purpose) Anypoint connector, validator, or scope that can be configured in the Mule application to filter duplicate sales orders on the basis of the unique ID field contained in each sales order record?

Configure a Cache scope to filter and store each record from the received file by the order ID

Configure a Database connector to filter and store each record by the order ID

Configure an Idempotent Message Validator component to filter each record by the order ID

Configure a watermark In an On New or Updated File event source to filter unique records by the order ID

Correct Answer: C

To filter duplicate sales orders based on a unique ID, the most idiomatic Anypoint component would be the Idempotent Message Validator. This component is specifically designed to ensure that each message processed is unique based on a specified key, such as an order ID. By using the Idempotent Message Validator, the Mule application can guarantee that each sales order is processed exactly once.
