Exam MCIA - Level 1 topic 1 question 99 discussion

Actual exam question from Mulesoft's MCIA - Level 1
Question #: 99
Topic #: 1
[All MCIA - Level 1 Questions]

A marketing organization is designing a Mule application to process campaign data. 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?

  • A. Use an in-memory repeatable stream
  • B. Use a file-stored non-repeatable stream
  • C. Use an in-memory non-repeatable stream
  • D. Use a file-stored repeatable stream

Selected Answer: D
I'll go with D. Use a file-stored repeatable stream. File-stored, because heap memory assigned to 0.2 vCores is 1 GB. If the size of the processed file is more than 1 GB and the disc storage isn't available, the application will crash. So the disc (file) storage is needed. Repeatable, since there are three downstream SFTP locations which expect different file formats, it can be assumed, that the mule application needs to access the stored data three times to transform them into three different formats.
