The RHCE^® Certification lab (RH299) is a facilitated lab environment for students to work at their own pace through a hands-on review prior to taking the Red Hat Certified Engineer (RHCE) exam (EX300).

Students attending this lab should have already completed their classroom training and simply be preparing to take or retake the exam. The delivery is focused primarily on lab time.

• Managing and troubleshooting systemd services during the boot process
• Network configuration and basic troubleshooting
• Managing local storage, creating and using file systems
• Firewall management with firewalld
• Automating installation of Red Hat Enterprise Linux^® using kickstart
• Manage SELinux settings
• Using NFS and Samba shared filesystems
• iSCSI initiator and target configuration
• Domain Name System (DNS) troubleshooting and caching name server
• Providing Network File System (NFS) and Server Message Block (SMB) file servers
• Apache HTTPD web server management
• MariaDB SQL database configuration
• Postfix Simple Mail Transfer Protocol (SMTP) nullclient for servers
• Bash scripting for automation

To qualify for this course, students must:

• Students should have already completed Red Hat System Administration I (RH124), Red Hat System Administration II (RH134), and Red Hat System Administration III (RH254) or equivalent training.
• It is highly recommended students take our online skills assessment  prior to enrolling in this course.
• Extensive UNIX administration experience by itself is not adequate for most students.
