This test measures administration skills using the Linux operating system. It is distribution-agnostic. Administrators running Mint, Debian, CentOS, Ubuntu, SUSE, and more can be assessed with this test. Note: All references to shell refer to Bash shell. While this test does include a sub-topic on Bash, IKM also offers a separate UNIX BASH SHELL SCRIPTING test for a more in-depth review of working with the shell. In addition, separate RED HAT ENTERPRISE LINUX (RHEL) ADMINISTRATION tests are also available.
