- Understand async versus sync execution type.
- Use @Timeout.
- Understand Retry policies and apply using @Retry.
- Understand and define Fallback.
- Understand and apply CircuitBreaker.
- Understand and apply Bulkhead.
- Understand and set up fault tolerance configuration.
Probe the state of a Quarkus application from another machine using MicroProfile Health Check
- Understand and implement the HealthCheck interface.

- Understand tags (labels).
- Understand and use metadata.
- Understand metric registry and @Metric.
- Expose metrics via REST API.
- Know required metrics.
- Understand Quarkus application metrics programming model.
MicroProfile Interoperable JWT RBAC on Quarkus applications: OpenID Connect (OIDC)-based JSON Web Tokens(JWT) for role-based access control (RBAC) of microservice endpoints
- Understand token-based authentication.
- Use JWT bearer tokens to protect services.
- Mark a JAX-RS application as requiring MP-JWT access control.
- Map MP-JWT tokens to Java EE container APIs.
Implement a Quarkus application and expose REST service endpoints with JAX-RS
- Understand REST concepts, particularly the application and use of the HTTP PUT, DELETE, GET, and POST methods.
- Know and use standard HTTP return codes.
- Implement RESTful root resource class.
- Expose a REST service using JAX-RS.
- Understand and use @Path, @Produce, and @Consume.
- Using CDI to integrate components.
- Using bean validation to ensure data format and consistency.
Simplified JPA mapping with Panache
- Understand the difference between the Active Record Pattern and the Repository Pattern.
- Use basic JPA to create, read, update, and delete persistent objects and their relationships.
- Map a bi-directional one-to-many relationship between two entities, including both sides of the association.
- Demonstrate the ability to perform the most common Panache operations and add custom entity methods.
Microprofile OpenAPI specification to document RESTful APIs
- Understand OpenAPI documents and the Swagger UI to discover remote services APIs.
- Demonstrate the ability to link to semantic versioning (semver) remote service endpoints.
- Understand how to produce the default and custom OpenAPI document to JAX-RS endpoints.
Interacting with REST APIs in Quarkus using the MicroProfile REST Client
- Understand the type-safe approach to invoke RESTful services over HTTP using the JAX-RS APIs.
- Understand REST concepts, particularly the application and use of the HTTP PUT, DELETE, GET, and POST methods.
- Demonstrate the ability to create and use a REST client to connect with a remote service.
- Parameterize and configure the REST client URI to invoke a specific remote microservice.
- Understand and use special additional client headers.
As with all Red Hat performance-based exams, configurations must persist after restart without intervention.
