RHCSA and RHCE 6 Certifications

This article is an introduction to the series of articles that will be presented on this site covering the Red Hat Certified System Administration (RHCSA EX200) and Red Hat Certified Engineer ( RHCE EX300) certification exams. You need to keep in mind the following notes when reading the associated articles.

Scope

I am trying to write a series of articles that cover the exam objectives that make up the RHCSA and RHCE certification exams. I am not trying to teach Linux administration from first principles.

Assumptions

Resources

While you are working through the exam objectives, your first stop for information should be the Red Hat Documentation, available for free online. This will not be available during the exams, so get used to using the man and info pages also.

The man pages provide very detailed explanations of specific commands, including all available flags and syntax variations. You should get used to reading them because they will probably be the major source of information during exams. Typically you will just specify the command of interest as a parameter, but some sections with suggest checking the information for a specific section of the documentation. In this case it can be specified using an integer before the command parameter.

# man vmstat
# man 8 vmstat

The info command is an alternative to the man command. Some info entries are similar to the man entries, but others are much more in the style of the HTML documentation, with better examples. If you are struggling to understand the man pages for a particular subject, you should probably try the info entry for the same command.

# info vmstat

You also have the information in the "/usr/share/doc" directory, but its usefulness is very much dependent on the feature you are looking for. Some entries are almost devoid of information. Some give detailed step-by-step usage notes. It is usually the last place I look for information, but worth checking out if you are stuck.

If you need more detail specifically about the exams, I suggest you get hold of a copy of one of the certification guides, such as the one by Michael Jang.
