QUESTION: 125

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

QUESTION: 127

An organization has defined a common object model in Java to mediate the communication between different Mule applications in a consistent way. A Mule application is being built to use this common object model to process responses from a SOAP API and a REST API and then write the processed results to an order management system.

The developers want Anypoint Studio to utilize these common objects to assist in creating mappings for various transformation steps in the Mule application.
What is the most idiomatic (used for its intended purpose) and performant way to utilize these common objects to map between the inbound and outbound systems in the Mule application?

Use JAXB (XML) and Jackson (JSON) data bindings
Use the WSS module
Use the Java module
Use the Transform Message component

Answer(s): A

QUESTION: 128

A marketing organization is designing a Mule application to process campaign dat

The Mule application will periodically check for a file in a SFTP location and process the records in the file. The size of the file can vary from 10MB to 5GB. Due to the limited availabiltty of vCores, the Mule application is deployed to a single CloudHub worker configured with vCore size 0.2.
The application must transform and send different formats of this file to three different downstream SFTP locations.
What is the most idiomatic (used for its intended purpose) and performant way to configure the SFTP operations or event sources to process the large files to support these deployment requirements?
Use an in-memory repeatable stream
Use a file-stored non-repeatable stream
Use an in-memory non-repeatable stream
Use a file-stored repeatable stream
