Red Hat Certified Engineer (RHCE): What You Need to Know

RHCE (Red Hat Certified Engineer) is one of the most recognized qualifications in the Linux and open-source community. It certifies that an IT professional possesses the skills to manage and automate environments for Red Hat Enterprise Linux (RHEL). This article covers everything about RHCE, including what the certification entails, how to prepare for the exam, and its benefits.

What is RHCE Certification?

The RHCE certification extends from the Red Hat Certified System Administrator (RHCSA) certificate, verifying the professional’s ability to tackle advanced topics like automation, security, and troubleshooting in Linux environments.

It is well-suited for system administration engineers and DevOps professionals working with Red Hat Enterprise Linux. An RHCE holder demonstrates advanced knowledge of Ansible automation, making them well-equipped to automate system deployment, configuration, and management at scale.

Key Topics Covered in RHCE

The RHCE exam tests not only Linux system administration but also automation using Ansible. Key topics include:

1. Automation with Ansible

   • Writing and deploying Ansible playbooks

   • Automating routine tasks such as server setup, software installation, and service management.

2. System Administration

   • Network service management: DNS, HTTP, databases

   • User account setup and privilege configuration

   • Storage and partitioning

3. Security

   • Firewall rules

   • SELinux configuration and enforcement for secure communication

4. Troubleshooting

   • System log analysis and performance problem resolution

   • General Linux system error tracking and correction

RHCE Exam Structure

The RHCE exam (EX294) is nearly four hours long and hands-on. Candidates complete tasks on live systems in a controlled environment. The key points are:

• No multiple-choice questions: It tests practical skills, not theory.

• Automation focus: Heavy emphasis on Ansible and automation.

• System administration: In addition to automation, traditional system admin tasks are included.
