XK0-006 practice examsFinished
CompTIA Linux+ V8 (XK0-006)
CompTIA Linux+ validates the skills to configure, manage, operate and troubleshoot Linux server environments: system management, services and users, security, automation with scripting, Python, Git and infrastructure as code, and troubleshooting.
What you get
Papers are cut from the bank and weighted like the real exam, and no question appears in two of them. Every wrong answer comes back on later days until you have it right.
What the exam covers
| System Management | 23% |
| Services and User Management | 20% |
| Security | 18% |
| Automation, Orchestration, and Scripting | 17% |
| Troubleshooting | 22% |
Two sample questions
1. Which kernel feature shows how much time tasks lose waiting for CPU, memory or I/O?
- The OOM killer score of each task
- dmesg output
- Pressure stall information — correct
- The Magic SysRq key combination
Why: /proc/pressure reports stall time per resource.
2. What is the main risk of a NOPASSWD rule for a broad command set?
- sudo stops writing any log entries
- Account compromise means instant root — correct
- The account becomes locked after use
- Commands run slower
Why: NOPASSWD removes a check, so a compromised account escalates instantly.
