RHCE, offered by Red Hat, validates your ability to manage, configure, and maintain Red Hat Enterprise Linux systems effectively. This article provides a detailed overview of the study points you need to master to succeed in the RHCE exam.

RHCE Study Points

1. Proficiency as a Red Hat Certified System Administrator

Before pursuing the RHCE certification, it’s essential to be well-versed in the responsibilities of a Red Hat Certified System Administrator (RHCSA). This knowledge forms the foundation for the advanced concepts you’ll encounter as an RHCE candidate.

2. Understanding and Using Essential Tools

RHCE candidates should be comfortable with the essential tools that are vital for Linux system administration, including tools for text editing, package management, and system monitoring. Mastery of these tools is crucial for efficient system management.

3. Operating Running Systems

You need to demonstrate the ability to manage running systems efficiently. This includes controlling services, configuring system startup and shutdown processes, and managing kernel modules.

4. Configuring Local Storage

Local storage management involves configuring disks, partitions, and logical volumes. You should be adept at handling storage devices and file systems to ensure optimal performance and data integrity.

5. Creating and Configuring File Systems

This RHCE competency area involves creating, mounting, unmounting, and maintaining file systems. Knowledge of the Filesystem Hierarchy Standard (FHS) is essential.

6. Deploying, Configuring, and Maintaining Systems

To excel as an RHCE, you must know how to deploy, configure, and maintain systems efficiently. This includes understanding system initialization and managing system services.

7. Managing Users and Groups

User and group management is a crucial aspect of system administration. RHCE candidates should be skilled in creating, modifying, and deleting user accounts and groups, and setting appropriate permissions.

8. Managing Security

Security is paramount in Linux system administration. RHCE candidates should understand the intricacies of security, including setting up firewalls, SELinux policies, and access controls.

9. Understanding Core Components of Ansible

Ansible is an essential tool for automation in Linux administration. RHCE candidates need to grasp the core components of Ansible, including inventories, modules, variables, facts, loops, conditional tasks, plays, handling task failures, playbooks, and configuration files.

10. Using Roles and Ansible Content Collections

Roles and Ansible Content Collections enable modular and scalable automation. You should be able to create, install, and use roles, Content Collections, and integrate them into playbooks to streamline your automation tasks.

11. Installing and Configuring an Ansible Control Node

RHCE candidates need to set up and configure the Ansible control node, including installing required packages, creating an inventory file, and configuring the Ansible environment.

12. Configuring Ansible Managed Nodes

Configuring the managed nodes involves creating and distributing SSH keys, configuring privilege escalation, and deploying files to the managed nodes. Understanding these tasks is essential for effective automation.

13. Creating Ansible Plays and Playbooks

You must know how to create plays and playbooks that automate standard RHCSA tasks, using Ansible modules that work with software packages, services, firewall rules, file systems, storage devices, file content, archiving, task scheduling, security, users, and groups.

14. Managing Content

Managing content in Ansible involves creating and using templates for customized configuration files and using Ansible Vault to protect sensitive data.


Becoming an RHCE involves mastering a wide range of skills, from Linux system administration fundamentals to advanced Ansible automation. The RHCE certification is highly regarded in the IT industry and can open doors to exciting career opportunities, increased earning potential, and recognition as an expert in Linux system administration. By diligently studying and practicing the RHCE study points outlined in this article, you’ll be well-prepared to tackle the RHCE exam and excel in your Linux administration career.
