Build my study plan

  1. Week 1: Read the exam guide; review the Developer II domains against your project experience and list gaps.
  2. Week 2: Maintainable apps (25%): build a parent POM, shared libraries, Maven-based deployment and environment-specific properties.
  3. Week 3: Performance and reliability (27%): implement Object Store caching, idempotent filters, until-successful, VM queues and reconnection strategies.
  4. Week 4: Security (20%): secure properties, TLS contexts, mTLS and client ID enforcement; monitoring with correlation IDs and custom logging.
  5. Week 5-6: Production-ready APIs with Autodiscovery and policies; take the official practice exam and timed reviews.

Make it yours: pick your exam date and weekly hours. We'll split your time by domain weight and give you a printable plan.

Exam-day tips

  • Performance and reliability is the largest domain; know which component gives idempotency vs retries vs persistence.
  • Understand Maven configuration for deployment (mule-maven-plugin, credentials, properties) at the XML level.
  • Know how API Autodiscovery links a running app to an API Manager instance.
  • Expect questions on secure properties encryption and TLS context configuration.
  • Answers that rely on manual console steps are usually wrong when a Maven or automated option exists.
