Published On: 22 November 2024

Objective

For IT professionals who use Red Hat Enterprise Linux (RHEL), earning the RHCSA (Red Hat Certified System Administrator) certification is a remarkable success. A broad range of practical abilities required to manage and administer Linux systems are tested in the certification exam. The first step to exam preparation and achievement is to comprehend the RHCSA exam objectives.

This resource provides information on how to approach preparing while outlining the key goals of the RHCSA exam. 

Key RHCSA Exam Objectives

1. Essential Tools and Commands

A core part of the RHCSA exam involves using essential tools and commands. You need to be proficient in accessing shell prompts, navigating file systems, and managing file permissions and links. Tools like vim, nano, grep, find, and awk are fundamental. Mastery of these tools is critical for managing and troubleshooting systems effectively.

Key Areas to Focus on:

  • Navigating file systems: Use commands like cd, ls, and pwd.

  • File management: Creating, deleting, and editing files with vim and nano.

  • File permissions: Managing read/write/execute permissions using chmod, chown, and chgrp.

  • Search and text processing: Using grep, awk, sed, and find to search, filter, and manipulate text.

Proficiency with these tools will significantly improve your ability to troubleshoot and manage Linux systems efficiently.

2. Operating Running Systems

This section of the RHCSA certification focuses on managing running systems. It includes booting systems into different targets, troubleshooting processes, and managing services with systemctl. Understanding local storage management, including creating and managing partitions and logical volumes, is also covered under the RHCSA exam objectives.

Key Areas to Focus on:

  • Boot targets and systemd: Understanding the systemd boot process and using systemctl to manage system services.

  • Troubleshooting processes: Monitoring processes with ps, top, and kill commands.

  • Managing local storage: Creating and managing partitions and Logical Volume Management (LVM) for disk management.

These tasks test your ability to handle real-time system issues and effectively manage system resources.

3. Configuring Local Storage and File Systems

Candidates are expected to demonstrate their ability to configure local storage, including creating and resizing partitions and logical volumes. Familiarity with xfs and ext4 file systems, as well as encryption and LVM, is essential. The exam also tests your skills in creating, mounting, and managing file systems, including setting permissions, attributes, and ACLs.

Key Areas to Focus on:

  • Partitioning and LVM: Creating and resizing partitions and managing logical volumes with LVM.

  • File system management: Working with xfs and ext4 file systems, including creating, mounting, and managing them.

  • Security: Implementing disk encryption and securing file system permissions.

  • ACLs (Access Control Lists): Configuring file system permissions beyond the basic user/group/other model.

You need to understand the nuances of local storage management, including optimizing and securing storage volumes and ensuring system performance.

4. Deploying, Configuring, and Maintaining Systems

Preparation for the RHCSA certification involves learning how to deploy, configure, and maintain systems. This includes installing Red Hat Enterprise Linux (RHEL), updating software, and configuring network settings.

Key Areas to Focus on:

  • RHEL installation: Understanding the installation process and configuring system settings such as networking and hostname.

  • System maintenance: Applying updates with yum or dnf, and managing system logs using journalctl.

  • Firewall and SELinux configuration: Configuring firewalld for security, and properly setting SELinux to enforce security policies.

These tasks ensure that your system is secure, stable, and up-to-date for long-term operations.

5. User and Group Management

Managing users and groups is an essential skill for any system administrator. The RHCSA exam requires you to create, delete, and modify user accounts and manage group memberships.  For more detailed information on this topic, click here.

Key Areas to Focus on:

  • User account management: Adding, removing, and modifying user accounts with useradd, usermod, and userdel.

  • Group management: Managing group memberships with groupadd and groupdel.

  • File permissions and user environments: Configuring user access and setting up user-specific configurations (e.g., .bashrc and environment variables).

This section ensures that you can control access to the system and maintain proper security standards for all users.

6. Security Practices

Security is a vital part of system administration. The RHCSA exam will test your knowledge of firewall configuration, SELinux, and SSH security measures.

Key Areas to Focus on:

  • Firewall: Configuring firewalld for controlling incoming and outgoing network traffic.

  • SELinux: Understanding SELinux modes (Enforcing, Permissive, Disabled) and managing its policies.

  • SSH security: Hardening SSH configurations, disabling root login, and using key-based authentication.Click here to know more.

Security measures are necessary for protecting the system from external threats and ensuring safe user access.

Strategies for Exam Preparation

Besides the cognitive comprehension of the exam objectives, it is very important to know how to prepare well in order to do well in the RHCSA exam. To help you prepare, here are some:

  • Hands-On Practice: Practical experience is critical. You can use virtual machines, labs, or platforms such as RHCSAGuru to simulate real-world scenarios and help build your confidence.

  • Study Resources: Get some in-depth study material, like the books by Sander van Vugt or online resources and videos that explain each exam goal.To assist with your preparation, we've put together a detailed blog on available free and paid resources. Click here to read more.
