Exam Snapshot: The Numbers You Must Memorize

- Format: Online, remotely proctored, multiple-choice, delivered through PSI Bridge.
- Length: 60 questions in 90 minutes - that's an average of 90 seconds per question.
- Passing score: 75%, meaning you need roughly 45 of 60 questions correct.
- Price: $250 for the exam only, which includes 12 months of exam eligibility and one retake.
- Prerequisites: None. Anyone can register and sit the exam.
- Validity: 2 years, renewed by retaking and passing LFCA before it expires.

Domain Breakdown at a Glance
LFCA is built from six domains, and they are not weighted equally. Knowing the weighting tells you exactly where to spend your limited study hours.
| Domain | Weight | Approx. Questions |
|---|---|---|
| Domain 1: Linux Fundamentals | 16% | ~10 |
| Domain 2: System Administration Fundamentals | 30% | ~18 |
| Domain 3: Cloud Computing Fundamentals | 18% | ~11 |
| Domain 4: Security Fundamentals | 14% | ~8 |
| Domain 5: DevOps Fundamentals | 12% | ~7 |
| Domain 6: IT Project Management Fundamentals | 10% | ~6 |
Notice that System Administration Fundamentals alone accounts for nearly a third of the exam - more than the bottom three domains combined. That single fact should shape your entire review schedule. For a full walkthrough of every subtopic inside each domain, the LFCA Exam Domains 2026: Complete Guide to All 6 Content Areas is the companion resource to this cheat sheet.
What Each Domain Actually Tests
Domain 1: Linux Fundamentals (16%)
Covers the command line, file systems, permissions, and basic shell usage that underpin every other domain.
- File and directory permissions (read/write/execute, ownership)
- Common command-line utilities for navigation and file manipulation
- Package management basics and process concepts
Domain 2: System Administration Fundamentals (30%)
The largest domain by far. Expect broad coverage of day-to-day admin tasks across servers, networking, and storage.
- User and group management, storage and disk basics
- Networking fundamentals: IP addressing, DNS, ports, troubleshooting concepts
- Service and process management, logging, and backups
Domain 3: Cloud Computing Fundamentals (18%)
Focuses on cloud service models, virtualization, and containers rather than any single vendor's console.
- IaaS, PaaS, SaaS distinctions and typical use cases
- Virtual machines vs. containers, and why organizations choose each
- Core cloud concepts: scalability, elasticity, shared responsibility
Domain 4: Security Fundamentals (14%)
Tests baseline security literacy - not deep penetration testing skills.
- Authentication vs. authorization, encryption basics
- Common threat types and mitigation concepts
- Security best practices for accounts, networks, and data
Domain 5: DevOps Fundamentals (12%)
Covers the culture and tooling of continuous delivery at a conceptual level.
- CI/CD pipeline concepts and version control basics
- Automation and infrastructure-as-code principles
- Monitoring and feedback loop concepts
Domain 6: IT Project Management Fundamentals (10%)
The smallest domain, but not one to skip - it tests project lifecycle and methodology vocabulary.
- Agile vs. waterfall concepts
- Roles, responsibilities, and communication in IT projects
- Risk, scope, and change management basics
Key Takeaway
Rank your review time to match domain weight: heaviest focus on Domain 2, then Domain 3, then a balanced pass through Domains 1, 4, 5, and 6. Don't spend equal hours on a 10% domain and a 30% domain.
Question Format and On-Screen Behavior
LFCA uses straightforward multiple-choice questions - there are no performance-based labs or command-line simulations. Every question is delivered and answered inside the PSI Bridge remote proctoring interface, so it's worth understanding the format before exam day rather than during it.
- All 60 questions are multiple-choice with a single correct answer per item.
- You can typically flag questions and return to them within the 90-minute window.
- Because it's remotely proctored, you'll need a private space, valid ID, and a working webcam - plan logistics in advance.
If you're still deciding whether the exam's difficulty matches your current knowledge level, How Hard Is the LFCA Exam? Complete Difficulty Guide 2026 walks through what makes certain questions tricky. And if you want data-informed expectations rather than guesswork, LFCA Pass Rate 2026: What the Data Shows covers what's publicly known about outcomes.
Registration, Fees, and Eligibility Windows
The registration mechanics are simple, but the details matter for planning your study timeline.
- Cost: $250 covers the exam attempt plus one retake if needed - no bundled courseware.
- Eligibility window: 12 months from purchase to schedule and sit your exam (and use the retake if applicable).
- No prerequisites: You do not need prior certifications, coursework, or verified work experience to register.
- Renewal: Certification is valid for 2 years; renewing simply means retaking and passing LFCA again before the expiration date.
For anyone comparing eligibility requirements against other IT certifications, LFCA Requirements 2026: Eligibility, Prerequisites & How to Qualify confirms there's no formal gatekeeping - which is part of why LFCA is often recommended as an entry point. To lock in your target test date around work or school commitments, check LFCA Exam Dates 2026: Testing Windows, Deadlines & Scheduling for how the scheduling windows function with PSI Bridge.
Final-Week Review Plan by Domain
If you're in the last stretch before test day, don't restart a generic study plan - triage by domain weight instead. This short timeline assumes you've already done foundational learning and are now in pure review mode.
System Administration Fundamentals (30%)
- Drill user/group management, networking basics, and service management until they're automatic
- Re-read any weak notes on backups, logging, and storage concepts
Cloud Computing Fundamentals (18%)
- Review service model differences (IaaS/PaaS/SaaS) and container vs. VM tradeoffs
Linux Fundamentals (16%) + Security Fundamentals (14%)
- Refresh command-line concepts and permission models
- Review authentication/authorization and encryption basics
DevOps (12%) + Project Management (10%)
- Skim CI/CD and automation concepts
- Review Agile vs. waterfall vocabulary and project roles
Full Practice Run + Rest
- Take a full-length timed practice test to confirm 90-second-per-question pacing
- Light review only; avoid cramming new material the night before
This condensed plan works best as a final review layer on top of a longer study cycle. For the complete multi-week preparation strategy, including how to sequence learning before you reach review mode, see the LFCA Study Guide 2026: How to Pass on Your First Attempt. You can also run timed practice questions modeled on the real domain weighting over at the practice test platform to confirm your pacing before exam day.
Who Hires LFCA Holders
LFCA is positioned as a foundational, vendor-neutral credential rather than a specialist certification, which shapes who values it. It's commonly used by:
- Career-changers moving into IT support, helpdesk, or junior sysadmin roles
- Students and bootcamp graduates who need a recognized credential without prior work experience
- Non-technical staff (project coordinators, technical sales, support) who need working literacy across Linux, cloud, security, and DevOps concepts
- Hiring managers screening entry-level applicants who want proof of baseline technical vocabulary
For a realistic look at how this credential translates into job listings and pay expectations, LFCA Jobs and LFCA Salary Guide 2026: Complete Earnings Analysis cover the practical outcomes. If you're still weighing whether it's worth the $250 and study time relative to alternatives, Is the LFCA Certification Worth It? Complete ROI Analysis 2026 lays out the tradeoffs directly.
