MCIA-Level-1 MuleSoft Exam Lab Questions

Explanation

Correct answer is For Each scope in the parent flow On Error Continue error handler in the child flow. You can extract below set of requirements from the question a) Records should be sent to downstream system in the same order that it was received in the array b) Any validation or communication failures should not prevent further processing of the remaining records First requirement can be met using For Each scope in the parent flow and second requirement can be met using On Error Continue scope in child flow so that error will be suppressed.

The MuleSoft-recommended best practice for sharing the connector and configuration information among multiple APIs is to use a Mule domain project. The steps are:

• Create a Mule domain project.
• Add the Database connector and its configuration to the domain project.
• Reference this domain project from each System API that needs to use the Database connector and configuration.

By using a domain project, you centralize the configuration and reuse it across multiple APIs. This approach ensures consistency, reduces duplication, and simplifies maintenance and updates to the connector configuration.

To ensure that data is encrypted both in-transit and at-rest, and to validate incoming requests to the Payment Processing API, the following approach is recommended:

• TLS Inbound Policy: Apply a Transport Layer Security (TLS) - Inbound policy in API Manager. This policy ensures that the data is encrypted during transmission and can be decrypted by the API Manager before it reaches the Mule application.
• Decryption: With the TLS policy applied, the message payload is decrypted when it is received by the API Manager.
• JSON Validation: After decryption, the Mule application can use the JSON Validation module to validate the structure and content of the JSON data. This ensures that the payload conforms to the specified format and contains valid data.

This approach ensures that data is securely transmitted and properly validated upon receipt.

Anypoint Platform provides the productivity advantage of automatic API proxy generation. This feature enables developers to quickly create proxies for their APIs, which act as intermediaries that forward requests to the appropriate backend services. Automatic proxy generation simplifies the process of securing and managing APIs, allowing developers to enforce policies, monitor traffic, and analyze usage without having to manually configure these aspects.
