Episode 1 — How Linux+ (XK0-006) tests you: domains, PBQs, pacing
Linux+ (XK0-006) evaluates whether you can translate concepts into admin decisions under time pressure, not whether you can recite trivia. This episode frames the exam...
Episode 2 — Audio-only study method: recall loops, pause-and-answer drills, exam-day mindset
This episode teaches an audio-first study system built for Linux+ outcomes: rapid recall, command intent recognition, and decision-making under constraints. Instead of...
Episode 3 — Boot flow story: bootloader → kernel → initrd/initramfs → userspace
Linux+ expects you to understand the boot process as a sequence of responsibilities, where each stage hands off control to the next. This episode walks the boot flow a...
Episode 4 — Boot configs and kernel parameters: what they change and why it breaks
Kernel parameters and boot configuration are exam-relevant because they sit at the boundary between “system won’t start” and “system starts but behaves wrong.” This ep...
Episode 5 — PXE boot in plain English: where it fits and what can fail
PXE boot is tested on Linux+ because it’s a clean example of network-based provisioning that relies on multiple services working in the right order. This episode expla...
Episode 6 — FHS tour: why where things live matters on exam questions
The Filesystem Hierarchy Standard (FHS) shows up on Linux+ because “where” is often the clue to “what,” especially when questions compress a scenario into a few paths ...
Episode 7 — Distros and packages: RPM-based vs dpkg-based thinking
Linux+ tests distribution awareness because real environments are mixed, and exam questions may describe commands, file locations, or package behaviors without naming ...
Episode 8 — Architectures and GUI stack: x86_64 vs AArch64, X vs Wayland, licensing basics
Architectures and desktop stacks are exam-relevant because they influence compatibility, performance expectations, and troubleshooting direction. This episode clarifie...
Episode 9 — Kernel modules: what they are, when they load, how to reason about them
Kernel modules matter on Linux+ because they explain how Linux supports diverse hardware and features without baking everything permanently into the kernel image. This...
Episode 10 — Hardware discovery mindset: CPU, memory, devices, and what looks wrong
Linux+ expects you to reason about hardware through the lens of symptoms and system reports, not through brand-specific knowledge. This episode teaches a hardware disc...
Episode 11 — initrd tools and custom hardware contexts: embedded and GPU use cases
Linux+ includes initrd/initramfs concepts because early boot is where “it worked yesterday” becomes “it can’t find root” after a kernel, driver, or storage change. Thi...
Episode 12 — Storage mental model: block devices → partitions → filesystem → mount
Storage questions on Linux+ are easier when you treat storage as a layered model rather than a pile of commands. This episode builds the foundational chain: block devi...
Episode 13 — Partitioning decisions: MBR vs GPT, growth, identifiers, verification
Partitioning shows up on Linux+ because it blends design choices with operational consequences, and the exam likes to test whether you understand the tradeoffs rather ...
Episode 14 — Filesystems in practice: ext4 vs xfs vs btrfs vs tmpfs, when and why
Linux+ tests filesystem knowledge because different filesystems imply different behaviors under load, different recovery options, and different best practices for grow...
Episode 15 — LVM part 1: PV, VG, LV concepts and why LVM exists
Logical Volume Manager (LVM) is a recurring Linux+ topic because it represents modern storage management: flexible allocation, online growth, and abstraction that make...
Episode 16 — LVM part 2: grow, extend, resize safely, and common failure patterns
Linux+ expects you to understand that “making storage bigger” is usually a sequence across layers, and LVM is where that sequence is most visible. This episode focuses...
Episode 17 — RAID basics for Linux+: what it protects, what it doesn’t, status thinking
RAID is tested on Linux+ because it’s a classic reliability topic that can be misunderstood in dangerous ways. This episode clarifies what RAID is for: combining disks...
Episode 18 — Mounting mastery: fstab, transient mounts, and avoiding boot-time surprises
Mounting is an essential Linux+ skill because Linux presents storage through the directory tree, and mounting mistakes are a common cause of boot failures and data con...
Episode 19 — Mount options that matter: security and stability tradeoffs
Linux+ questions often use mount options as the subtle detail that explains why a system is secure, fragile, fast, or failing. This episode introduces mount options as...
Episode 20 — Network mounts overview: NFS vs SMB/Samba and what symptoms look like
Network mounts are on Linux+ because they test whether you can reason about shared storage as a service dependency, not just a directory. This episode explains NFS and...
