15.50Deployment pipeline example

A good concrete interview answer:

GitHub PR
   ↓
GitHub Actions / Jenkins
   ↓
mvn clean test
   ↓
MUnit passes
   ↓
mvn package
   ↓
publish versioned artifact
   ↓
deploy QA using Mule Maven Plugin
   ↓
wait for RUNNING
   ↓
run smoke/API tests
   ↓
approval
   ↓
promote same artifact to PROD
   ↓
production health/smoke validation
   ↓
monitor error/latency metrics

That is enough to sound completely comfortable with the lifecycle.
