Linux Intro — Knowledge Check
You covered kernel vs distro vs shell, Ubuntu vs Kali vs Parrot (including why Kali is not a daily driver), and the FHS map from / through /etc and /var/log. These ten APPLY scenarios test judgment on a real box — not vocabulary flashcards. Choose the best defensive or lab move.
Knowledge Check
APPLY: You SSH into a lab VM you own. A teammate asks you to "just chmod 777 / so the GUI file manager stops complaining." What should you do?
Multiple choice
Knowledge Check
APPLY: A news site is down. You want "real Linux practice" and start scanning the site from your Kali VM. Best assessment?
Multiple choice
Knowledge Check
APPLY: After cat /etc/os-release you see Ubuntu 24.04 LTS. You need Nmap for a weekend CTF on a throwaway VM. Sensible plan?
Multiple choice
Knowledge Check
APPLY: An intern says "the kernel is Kali, the distro is bash, and the shell is apt." Which correction is accurate?
Multiple choice
Knowledge Check
APPLY: You need to leave a lab notes folder that survives reboot and is obviously yours. Where?
Multiple choice
Knowledge Check
APPLY: True or False: Android phones using a Linux kernel means installing Kali on a VM is unnecessary because you already "have Linux" in your pocket for server administration.
True or False
Knowledge Check
APPLY: A web service on your VM started serving the wrong page after a teammate "tweaked SSH and nginx." You also want timestamps of restarts. Where do you look first?
Multiple choice
Knowledge Check
APPLY: You are in /home/sam/downloads. You type cat os-release and get "No such file." The file you wanted is the system distro file. What went wrong?
Multiple choice
Knowledge Check
APPLY: True or False: Because Kali, Ubuntu, and Parrot are Debian-family, a beginner should treat Kali as the default daily OS "since apt is the same."
True or False
Knowledge Check
APPLY: During IR on a Linux box you own in lab, you find a weird binary in /tmp and a new file under /opt. What is the most accurate first read of those locations?
