What Are Exam Topics for RHCSA Certification Test?

The RHCSA certification exam assesses a candidate's knowledge and competency in a vast range of IT areas. Thus, the student must demonstrate their aptitude in the following domains:

• Basic Networking — Here, students have to demonstrate they can set up IPv4 and IPv6 addresses, operate with hostname resolution, tweak networking solutions to launch on their own at boot, and also restrict network access with the help of Firewall.
• Containers — This last domain checks if candidates can do things such as withdraw container images from a remote registry, inspect container images, use commands such as skopeo and podman to carry out container management, list running containers, and connect persistent storage to a container.
• Security — This exam objective asks students to tweak firewall configurations, use file access control lists, set up key-based authentication for SSH, configure various modes for SELinux, and to identify SELinux files. In addition, you will have to know how to deal with SELinux policies and settings.
• Running Systems — In this section, skills such as booting and rebooting a system perfectly, booting systems into another target manually, gaining access to a system by intervening in the boot process, killing memory intensive processes, scheduling a process, managing tuning profiles, finding as well as analyzing system log files and journals, saving system journals, stopping and checking the condition of network services, and transferring files safely among systems will all be tested.
• Local Storage — This area checks a candidate's ability to make and delete partitions on MBR and GPT disks, remove physical volumes, designate physical volumes to volume groups, create and erase logical volumes, set up systems so they mount file systems according to their universally unique ID (UUID) or label when they boot, add extra partitions and logical volumes, and lastly, change to another system non-destructively.
• Simple Shell Scripts — This next category checks whether test-takers can run codes with conditional statements, process files with looping constructions, process inputs for scripts, processing shell command output, and exit codes.
• System Deployment — For this part, candidates will have to use at & cron to schedule tasks, stop services and set up services to start on their own during boot, configure systems so they boot into another target automatically, set up time service clients, install software from a remote repository or from the Red Hat Network, handle package module streams, and lastly, customize the system bootloader.
• Essential Tools — This first area will evaluate how well examinees can use shell prompts and make commands in the right syntax, use input-output redirection, analyze texts with grep and regular expressions, use SSH to get into remote systems, log in and switch users, use star and bzip2 to store and unpack files, edit text files, delete and transfer files as well as directories, make soft and hard links, set and change ugo/rwx permissions, and finally, locate and utilize documentation for systems.
• File Systems — Here, candidates need to mount and use ext4 and xfs file systems, use NFS to increase & decrease file systems, broaden logical volumes, design & implement set-GID directories for collaboration, compress disks, maintain layered storage, and finally, assess and rectify file permission issues.
• Users and Groups — In this next segment, examinees must be skilled at configuring and customizing local user accounts, changing passwords for such accounts, tweaking local groups as well as group memberships, and also setting up superuser access.
