LFCS Practice Exam 02 is a second, independent hands-on assessment of practical Linux administration. Its 20 challenges cover operations and deployment, networking, storage, essential commands, and users and groups through scenarios different from Practice Exam 01. The recommended total duration is 120 minutes; each task is worth 5 points, and 67 points is the simulated LabEx passing threshold.
You will work from goals and acceptance criteria rather than guided solutions. Each challenge opens in a fresh Ubuntu 22.04 environment where you must inspect the current state, implement the requested change, and prove live behavior, persistent configuration, generated evidence, or access controls as appropriate.
What You Will Learn
- Create systemd service timers, repair service environment settings, configure a local APT repository, and run a persistent Docker worker
- Maintain a libvirt domain with defined CPU, memory, autostart, and qcow2 disk settings
- Configure IPv6 state, SSH client aliases, local port redirection, and a reverse proxy while diagnosing live listeners
- Extend LVM storage, mount a constrained tmpfs, configure a read-only automount, and repair an ext4 filesystem image
- Restore a known-good configuration from Git and extract precise evidence from staged authentication logs
- Produce a filtered, checksummed backup and diagnose a systemd resource-constraint failure without altering the evidence
- Apply access and default ACLs and create a locked, non-login service account with controlled groups and aging settings
Who This Course Is For
This course is for Linux administrators, DevOps engineers, support professionals, and LFCS candidates who want another complete exam-style set or a demanding check of independent troubleshooting skills. It is intended for learners who already perform common Linux administration tasks from the command line.
Prerequisites: Comfortable use of the Linux shell, sudo, files and permissions, packages, systemd, networking, storage, Git, and user administration. Basic familiarity with Docker, LVM, ACLs, and virtualization concepts is helpful.
Learning environment: Twenty isolated browser-accessible Ubuntu 22.04 environments, including a desktop-capable VM for the libvirt task. Required repositories, packages, services, disk images, Git history, logs, keys, configuration files, and container or virtual-machine assets are staged locally; no state is shared between challenges.
Frequently Asked Questions
Is Practice Exam 02 a continuation of Practice Exam 01?
No. It is a separate full practice form with different tasks. You can take either one first, and no users, services, files, mounts, or other state carry between the two courses.
Is this an official LFCS exam?
No. It is an independent LabEx practice resource. The 120-minute recommendation, 100-point scale, and 67-point threshold are simulated settings and do not produce an official LFCS result.
Will I receive step-by-step commands?
No. Each challenge provides a goal and measurable acceptance criteria, then automatically checks the final state. The course assesses whether you can select commands, diagnose problems, and verify results on your own.
Do the virtualization and networking tasks require external infrastructure?
No. The libvirt domain, qcow2 disks, local services, IPv6 interface, SSH material, and proxy endpoints are prepared inside the relevant VM. You perform real local administration without needing cloud accounts or remote servers.
