Policies consist of what two files?

• A. A deployable JAR file that contains the policy implementation, and a YAML Configuration File where the policy parameters and metadata are defined.
• B. An XML template and a YAML file
• C. A single YAML file
• D. A Java source file and a resources directory

Answer: (A)

Policies in MuleSoft are delivered as a pair of artifacts: the runtime implementation packaged as a deployable JAR, and a YAML configuration file that defines the policy’s parameters and metadata. The JAR contains the actual policy logic that runs when the policy is applied to an API, while the YAML file provides the necessary configuration—such as the policy name, version, and parameter definitions—that the API Manager uses to apply and manage the policy. Without the JAR, there is no policy code to execute; without the YAML, the platform wouldn’t have the configuration to apply or parameterize the policy. The other options don’t fit because policies aren’t defined by an XML template, a single YAML file alone, or a Java source file with a resources directory at deployment time.
