After completing the Red Hat RHCA certification, you can advance to become an intermediate and senior operation and maintenance engineer, and enter a high-tech position in a large factory ! After learning, you can get started with professional system tuning, Ansible automated operation and maintenance, Openstack+Ceph cloud computing management officially recognized by Red Hat, and master Zabbix, Prometheus, Saltstack and other extended skills!

Red Hat's certification course is a combination of theory and experiment. Each chapter in Red Hat's official textbooks has a matching practice experiment. The ratio of theory and experiment is basically close to 1:1.

The exams of Red Hat certification are all practical questions on the computer , not multiple-choice questions in the traditional sense. "It is a test item based on practical operation ability, and it mainly examines the practical ability of candidates in the actual operating system." One of the reasons for the high gold content of Red Hat certification .
