LFCS: LFCS Knowledge Companion
Build the Linux knowledge behind LFCS hands-on administration
$79 practice exams are gatekeeping. Mine are $9 because it should be. Written by someone who works in cloud and AI at Microsoft NZ — for people like us.
I just passed with a 777 (Yes, Seriously). This video helped me tremendously.

Frequently Asked Questions
How long is the LFCS exam?
The official LFCS exam is 120 minutes long. This bank is untimed revision material, so it does not reproduce that time pressure. Follow official exam guidance and practise the published skills hands-on.
What are the prerequisites for LFCS?
Prerequisites for LFCS: None. Our explanations are detailed, but this revision material does not replace hands-on practice or any official preparation requirements.
Is the LFCS Knowledge Companion MCQ learning companion worth it?
Read this first — The official LFCS exam is a two-hour hands-on command-line assessment. This product contains multiple-choice learning questions only, not a hands-on lab or exam simulator. Scores do not assess practical skill or predict an LFCS result. Twenty questions are free; full access is $9 for one year. No official exam, course, simulator access, voucher, logo, badge or endorsement is included. With that in mind, our 250-question bank includes two study modes (Study, and Flashcards with spaced repetition), detailed explanations for every answer, adaptive question selection, and progress tracking across all 5 domains. 20 practice questions are free with no account needed. Full access is $9 for 1 year.
How do I prepare for the official LFCS assessment?
Start with Study Mode for instant feedback and concept learning. This bank is untimed revision material rather than a simulation of the real exam. Practise the published skills in the relevant tools and follow official preparation requirements. Use Flashcards with spaced repetition to retain key facts long-term. Track your results on attempted questions across the domains. These scores do not assess practical skills or predict an exam result.
How does purchasing work?
Click "Unlock $9" above → pay securely via Stripe → all 250 questions unlock straight away in that browser. Your licence key is shown on screen and emailed to you from noreply@aguidetocloud.com — you only need to enter it on another device or browser. No account needed. Each cert is purchased separately at $9 for 1 year of access.
Can I use my purchase on multiple devices?
Yes. Your licence key (e.g. GD-XXXX-XXXX-XXXX) works on up to 3 devices — phone, tablet, laptop, desktop. On each new device, go to the practice page and enter your key.
Do I have to enter my licence key every time I visit?
No. You enter your key once per browser and it's remembered on that device until your 1-year access expires — so on your usual device you just open the page and start. You'd only re-enter it if you clear your browser data or switch browsers. Tip: avoid private/incognito windows, since they forget the key when they close.
What if I lose my licence key?
Your key is in the licence key email from noreply@aguidetocloud.com, with a subject starting "Your licence key for" — a separate email from the Stripe payment receipt. Check your inbox (and spam folder). If you can't find it, email aguidetocloud@gmail.com and we'll look it up.
