# Introduction In Linux systems, it's common to have multiple users sharing the same environment. As a system administrator, you need to be proficient in managing user accounts and switching between them. This challenge will test your skills in user management and authentication in a Linux environment. ## Environment LabEx uses Red Hat Universal Base Image 9 (UBI9) to simulate the exam environment. It may not be identical to the actual RHCSA exam environment, but it provides a good representation of the tasks you'll encounter. There are two users in the environment: - `labex`: A standard user with sudo privileges, password: `labex`. - `root`: The system administrator, password: `redhat`. The challenge features real exam questions, along with explanations, requirements, and automated verification scripts to help you confirm task completion. It effectively simulates the knowledge areas covered in the RHCSA exam.
