Implement performant and reliable Mule applications had questions about resolving throughput and stability problems, such as whether to use streaming, batch processing, connection pooling, or retry/circuit-breaker patterns for a given scenario. I cleared the exam after drilling on streaming vs buffering, connector configuration for pooling, and backoff/retry strategies to ensure nonblocking, fault-tolerant flows.

Happy to say I passed Salesforce MuleSoft Developer II, but monitoring and troubleshooting was the area that surprised me with how practical it was. Spending time in Anypoint Monitoring and learning what good dashboards and alerts look like paid off.

Implement monitorable Mule applications included troubleshooting vignettes that required choosing the right metrics, logging strategy, or alert threshold to catch a silent failure. I passed and recommend getting hands-on with Anypoint Monitoring, custom metrics, log patterns, and setting meaningful alerts and dashboards so you can map symptoms to the right metric.

Implement maintainable and modular Mule applications and their Maven builds often showed up as architecture-style questions asking which project layout or POM configuration supports shared libraries and domain projects. I managed to pass the exam by practicing multi-module Maven setups and understanding dependency scopes, Mule domains, and when to externalize common code.

Expose production-ready Anypoint Platform-managed APIs from Mule applications came up as scenario questions where you must pick the right API Manager policies, proxy placement, and versioning approach for a live traffic requirement. I passed the exam and thanks Pass4Success for providing good collection of exam questions for preparation in short time, so focus on how RAML/OAS definitions, API proxy vs direct deployment, and policy order impact runtime behavior.

Free Salesforce Salesforce Certified MuleSoft Developer II (Mule-Dev-301) Exam Actual Questions

Note: Premium Questions for Salesforce Certified MuleSoft Developer II (Mule-Dev-301) were last updated On Aug. 03, 2026 (see below)

Question #1

Which type of cache invalidation does the Cache scope support without having to write any additional code?

Reveal Solution Hide Solution
Correct Answer: C

The Cache scope supports time to live (TTL) as a cache invalidation strategy without having to write any additional code. TTL specifies how long the cached response is valid before it expires and needs to be refreshed. The Cache scope also supports custom invalidation strategies using MEL or DataWeave expressions. Reference: https://docs.mulesoft.com/mule-runtime/4.3/cache-scope#cache_invalidation


Question #2

A custom policy needs to be developed to intercept all cutbound HTTP requests made by Mule applications.

Which XML element must be used to intercept outbound HTTP requests?

Reveal Solution Hide Solution
Correct Answer: B

The http-policy:processor element is used to intercept outbound HTTP requests made by Mule applications. It allows customizing the request before it is sent to the target API and modifying the response after it is received from the target API. Reference: https://docs.mulesoft.com/api-manager/2.x/policy-mule4-custom-policy#policy-xml-file


Question #3

A new Mule project has been created in Anypoint Studio with the default settings.

Which file inside the Mule project must be modified before using Maven to successfully deploy the application?

Reveal Solution Hide Solution
Correct Answer: C

To use Maven to successfully deploy the application, the developer needs to modify the pom.xml file inside the Mule project. The pom.xml file contains the configuration and dependencies of the Mule application, as well as the deployment information such as the CloudHub region, environment, and worker size. The developer needs to specify these properties in the pom.xml file before using Maven to deploy the application. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#application-deployment-descriptor


Question #4

Which command is used to convert a JKS keystore to PKCS12?

Reveal Solution Hide Solution
Correct Answer: B

To convert a JKS keystore to PKCS12, the developer needs to use the keytool-importkeystore command with the following options: -srckeystore keystore.jks -srcstoretype JKS -destkeystore keystore.p12 -deststoretype PKCS12. This command imports all entries from a source JKS keystore (keystore.jks) into a destination PKCS12 keystore (keystore.p12). Reference: https://docs.oracle.com/en/java/javase/11/tools/keytool.html#GUID-5990A2E4-78E3-47B7-AE75-6D1826259549


Question #5

What is the MuleSoft recommended method to encrypt sensitive property data?

Reveal Solution Hide Solution
Correct Answer: A

The MuleSoft recommended method to encrypt sensitive property data is to use the Secure Properties Tool that comes with Anypoint Studio. This tool allows encrypting properties files with a secret key and then decrypting them at runtime using the same key. The encryption key and sensitive data should be different for each environment to ensure security and avoid accidental exposure of sensitive data. Reference: https://docs.mulesoft.com/mule-runtime/4.3/secure-configuration-properties
