RedHat Certifications-RHCSA and RHCA
If there’s one major star in the vendor-specific Linux certification firmament, it’s got to be Red Hat. The company has major market presence and serious duration as a commercial provider of Linux platforms and technologies.
Like so many other certification programs, Red Hat offers a typical administrator → engineer → architect certification ladder; unlike many other such programs, however, it offers highly regarded and valued credentials at each rung, along with demanding and hands-on oriented exams and an excellent training curriculum to match. All exams for the following Red Hat certifications are performance based and last two hours or longer.
The giveaway for Red Hat certifications is that all come with acronyms that start with RH, as follows:
• Red Hat Certified Systems Administrator RHCSA — this foundation Red Hat certification vets essential skills in handling files, working at the command line and using system documentation, along with managing systems, configuring storage partitions and logical volumes and more.
• Red Hat Certified Engineer RHCE — this cornerstone Red Hat certification is designed to test and validate the skills and knowledge necessary to work as a senior-level Linux system administrator. Topics covered include advanced IP routing and services, managing runtime kernel behavior, working with iSCSI, automating maintenance tasks with shell scripts and working with networking services for Web, FTP, NFS, SMB, SMTP, SSH and more. An RHSCA is a prerequisite for the RHCE.
• Red Hat Certified Architect RHCA — Red Hat’s pinnacle certification takes the RHCE or Red hat Certified JBoss Developer RHCJD as a prerequisite, and also requires candidates to earn at least five certificates of expertise within one of the concentrations: Datacenter, Cloud, Application Platform or Enterprise Application Development. Expertise areas include OpenStack, hybrid cloud storage, JBoss administration, platform as a service PaaS, deployment and systems management, virtualization, clustering and storage management, server hardening and performance tuning. Each certificate requires passing a performance-based exam, which lasts up to six hours.
