RHCSA Rapid Track
Course update
An updated version of this course is available that uses a newer version of Red Hat Enterprise Linux in the lab environment. Therefore, the RHEL 9.0 version of the lab environment will retire on December 31, 2024. Please complete any work in this lab environment before it is removed on December 31, 2024. For the most up-to-date version of this course, we recommend moving to the RHEL 9.3 version.
You might see the following lab activity types in this course:
A guided exercise is a hands-on practice exercise that follows a presentation section. It walks you through a procedure to perform, step by step.
A quiz is typically used when checking knowledge-based learning, or when a hands-on activity is impractical for some other reason.
An end-of-chapter lab is a gradable hands-on activity to help you to check your learning. You work through a set of high-level steps, based on the guided exercises in that chapter, but the steps do not walk you through every command. A solution is provided with a step-by-step walk-through.
A comprehensive review lab is used at the end of the course. It is also a gradable hands-on activity, and might cover content from the entire course. You work through a specification of what to accomplish in the activity, without receiving the specific steps to do so. Again, a solution is provided with a step-by-step walk-through that meets the specification.
To prepare your lab environment at the start of each hands-on activity, run the lab start command with a specified activity name from the activity's instructions.
Likewise, at the end of each hands-on activity, run the lab finish command with that same activity name to clean up after the activity.
Each hands-on activity has a unique name within a course.
The syntax for running an exercise script is as follows:
[student@workstation ~]$ lab action exerciseThe action is a choice of start, grade, or finish.
All exercises support start and finish.
Only end-of-chapter labs and comprehensive review labs support grade.
- start
The
startaction verifies the required resources to begin an exercise. It might include configuring settings, creating resources, checking prerequisite services, and verifying necessary outcomes from previous exercises. You can take an exercise at any time, even without taking preceding exercises.- grade
For gradable activities, the
gradeaction directs thelabcommand to evaluate your work, and shows a list of grading criteria with aPASSorFAILstatus for each. To achieve aPASSstatus for all criteria, fix the failures and rerun thegradeaction.- finish
The
finishaction cleans up resources that were configured during the exercise. You can take an exercise as many times as you want.
The lab command supports tab completion.
For example, to list all exercises that you can start, enter lab start and then press the Tab key twice.
