Exam MCIA - Level 1 topic 1 question 21 discussion

Actual exam question from Mulesoft's MCIA - Level 1
Question #: 21
Topic #: 1
[All MCIA - Level 1 Questions]

Refer to the exhibit. A business process involves the receipt of a file from an external vendor over SFTP. The file needs to be parsed and its content processed, validated, and ultimately persisted to a database. The delivery mechanism is expected to change in the future as more vendors send similar files using other mechanisms such as file transfer or HTTP POST.
What is the most effective way to design for these requirements in order to minimize the impact of future change?

  • A. Use a composite data source so files can be retrieved from various sources and delivered to a MuleSoft Batch Job for processing
  • B. Use a MuleSoft Scatter-Gather and a MuleSoft Batch Job to handle the different files coming from different sources
  • C. Create a Process API to receive the file and process it using a MuleSoft Batch Job while delegating the data save process to a System API
  • D. Create an API that receives the file and invokes a Process API with the data contained in the file, then have the Process API process the data using a MuleSoft Batch Job and other System APIs as needed

It should be D. Key here is there will be future changes. You want to design so that Process API does not need any change. Fronting Process API with another API layer gurantees that Process API will not need to change for any future changes. Everything else can remain same for future changes, just the API that sends requests to Process API need to change.
