About RHCA

Red Hat Certified Architect (RHCA) - Complete Learning Path & Exam Guide

The RHCA (Red Hat Certified Architect) is the highest level of certification in Red Hat's credentialing program, designed for senior Linux professionals, cloud architects, and DevOps engineers. Unlike RHCSA and RHCE (which are single exams), RHCA requires earning five additional Red Hat certifications after RHCE.


📌 RHCA Requirements

  1. Prerequisite: You must have a valid RHCE certification (either from RHEL 8 or RHEL 9).

  2. Total Exams Needed5 Red Hat Specialist exams (from the list below).

  3. Validity: Each exam extends your RHCE expiration date by 3 years.

  4. Cost: Each exam costs 400−400−600 USD (varies by region).


📚 RHCA Learning Paths (Specializations)

Red Hat offers multiple tracks for RHCA, depending on your career focus. You can mix and match exams from different tracks.

1. Cloud & Automation Track (DevOps Focus)

  • EX447 (Advanced Automation: Ansible Best Practices)

  • EX280 (OpenShift Administration)

  • EX188 (Containerized Application Development)

  • EX374 (Linux Security)

  • EX358 (Ansible for Networking)

2. Enterprise Applications & Development

  • EX183 (Red Hat Certified Developer)

  • EX280 (OpenShift Administration)

  • EX188 (Container Development)

  • EX442 (Performance Tuning)

  • EX210 (OpenStack Administration)

3. Infrastructure & Security Track

  • EX413 (Server Hardening & Compliance)

  • EX342 (High Availability Clustering)

  • EX442 (Performance Tuning)

  • EX374 (Linux Security)

  • EX280 (OpenShift Administration)


📝 RHCA Exam Format

  • Hands-on, performance-based (no multiple-choice questions).

  • 3-4 hours per exam.

  • Passing score: Typically 70%+ (varies by exam).

  • Real-world tasks: You must configure systems, troubleshoot issues, and implement solutions.


🚀 Recommended Study Approach

  1. Start with RHCE (if not already certified).

  2. Choose a specialization (Cloud, Security, DevOps, etc.).

  3. Take official Red Hat training (recommended but not mandatory):

    • DO447 (Advanced Ansible)

    • DO280 (OpenShift Administration)

    • RH413 (Security)

  4. Practice in a lab environment (use Red Hat Developer Subscription for free RHEL access).

  5. Use study guides & practice tests (e.g., Sander van Vugt’s RHCA books).


💡 Tips for Success

✔ Focus on automation (Ansible is key in many RHCA exams).
✔ Master OpenShift & containers (EX280/EX288 are popular choices).
✔ Learn security deeply (SELinux, OpenSCAP, firewalld).
✔ Join Red Hat communities (for troubleshooting help).


🎯 Is RHCA Worth It?

✅ For Cloud/DevOps Engineers: Highly valuable (OpenShift, Ansible, Kubernetes).
✅ For Linux Architects: Establishes deep expertise.
✅ For Security Specialists: EX374 & EX413 are gold standards.
