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 Mar. 05, 2026 (see below)

Question #1

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 #2

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


Question #3

A Mule application need to invoice an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to compute its process.

Which implementation should be used to get response data from the external API after it completes processing?

Reveal Solution Hide Solution
Correct Answer: D

To get response data from the external API after it completes processing, the developer should expose an HTTP callback API in Mule and register it with the external system. This way, the external API can invoke the callback API with the response data when it is ready, instead of making the Mule application wait for a long time or poll for a response repeatedly. Reference: https://docs.mulesoft.com/mule-runtime/4.3/http-listener-ref#callback


Question #5

A system API that communicates to an underlying MySQL database is deploying to CloudHub. The DevOps team requires a readiness endpoint to monitor all system APIs.

Which strategy should be used to implement this endpoint?

Reveal Solution Hide Solution
Correct Answer: A

To implement a readiness endpoint to monitor all system APIs, the developer should create a dedicated endpoint that responds with the API status and reachability of the underlying systems. This way, the DevOps team can check if the system API is ready to receive requests and if it can communicate with its backend systems without errors. Reference: https://docs.mulesoft.com/mule-runtime/4.3/deployment-strategies#readiness-probes
