Practice labs
- Try confusable command options in the terminal: You run ten confusable option pairs for tar, find, grep and chmod on sample files and write the difference into an answer file.
- Pick and run the command that fits the task: You solve twelve short tasks from a checker script with the right command and hand in each output.
- One-liner sprint: In twenty-five minutes you solve eight text-processing, search and permission tasks with one-liners and see the script's score.
- Write key file paths from memory: You answer twenty questions on where account, network, service and log files live and verify the paths exist on the system.
- Match each setting to its configuration file: You match fifteen settings to the file or directory where they are made and note the equivalents on other distributions.
- Build a Debian versus RPM family difference table: You try the commands doing the same job in both families for packages, networking, firewall and services in the lab and put them in a table.
- Read the fields in ls and ps output: In ten output fragments you interpret the permission string, ownership, process state and priority fields and answer the questions.
- Name the fault from service and journal output: In eight systemctl and journalctl outputs you determine why the service isn't running and write the command that fixes it.
- Find the inconsistency in storage and network output: Reading lsblk, df, ip and ss output together you point out the misconfigured item in six scenarios.
- Choose where to look first in a scenario: For ten problem scenarios you pick the first diagnostic command to run and write why in one line.
- Choose the narrowest fix in security scenarios: In ten scenarios on permissions, sudo, firewalls and mandatory access control you choose the narrowest change that solves the problem.
- Solve mixed scenarios on a live system: In twenty-five minutes you solve and verify a permission, a service, a storage and a script scenario on a live system.
