Which file defines the policy artifact descriptor in a MuleSoft policy project?

• A. The pom.xml
• B. The mule-artifact.json descriptor
• C. The manifest.mf
• D. The policy YAML

Answer: (B)

The key thing being tested is where the policy artifact is described so the Mule runtime and Anypoint Platform can recognize and load the policy correctly. In a policy project, that descriptor is defined in the file at the root named mule-artifact.json. This file carries the metadata that identifies the policy artifact—its name, version, type, and the resources that implement the policy—so the platform knows how to install, manage, and execute the policy.

The other files have different roles: the pom.xml handles Maven build configuration, the manifest.mf is part of the JAR packaging metadata, and a policy YAML (if present) is typically used for policy configuration or behavior details, not for describing the artifact itself.
