- A
Java Applets
Why wrong: Applets are client-side and deprecated.
- B
Java EE with EJB
Why wrong: EJB is a heavyweight specification, not optimal for lightweight microservices.
- C
Java EE with JAX-RS RESTful Web Services
Correct. Java EE with JAX-RS is the standard Java technology for RESTful web services, enabling independent services to communicate over a network via HTTP. JAX-RS annotations like @Path and @GET simplify service creation.
- D
Java RMI
Why wrong: RMI is for remote method calls, not for REST-based microservices.
Question 167 of 509
1Z0-811 JAX-RS Practice Question
This 1Z0-811 practice question tests your understanding of what is java. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: jAX-RS. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A team is designing a new system that requires deploying independent services communicating over a network. Which Java technology is most suitable for this architecture?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Java EE with JAX-RS RESTful Web Services
Option C is correct because Java EE with JAX-RS (Java API for RESTful Web Services) enables building RESTful services that communicate over HTTP, which is ideal for independent services in a microservices architecture. Option A is incorrect: Java Applets are client-side components that run in a browser and are not suitable for server-side network communication. Option B is incorrect: Java EE with EJB is a heavyweight, monolithic approach that is less suited for modern microservices architectures. Option D is incorrect: Java RMI is a remote method invocation protocol for tightly coupled distributed systems, not designed for lightweight RESTful services.
Key principle: JAX-RS

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates may mistakenly choose Spring Boot because it is popular, but the question specifically asks for a 'Java technology' from the core Java ecosystem. JAX-RS is the correct standard choice.
Detailed technical explanation
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- JAX-RS
- Microservices
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. JAX-RS Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
