How CertGrid questions are reviewed
Every bank is written and maintained by our team against the vendor's current skills outline - not copied or scraped from exam content. Each question is mapped to a published concept, every answer carries an explanation covering why the right option is right and why each wrong option is wrong, and banks are re-reviewed whenever the exam changes. Individual exam pages show the date each bank was last reviewed.
Frequently asked questions
Which Linux certification should I start with?
CompTIA Linux+ and LPIC-1 are the most common entry points and are vendor-neutral. Red Hat RHCSA is the top choice if you work in a Red Hat / RHEL environment, and LFCS is the Linux Foundation equivalent.
Are these official Linux exam questions?
No. CertGrid is an independent practice platform. We do not provide real or leaked exam questions. Our questions are original and designed to help you practice the concepts, commands, and difficulty style of Linux certification exams.
Are RHCSA and LFCS not hands-on exams?
The real RHCSA and LFCS are performance-based (you complete tasks on a live system). Our questions build the command-line knowledge, configuration, and troubleshooting patterns those tasks rely on, and fully cover the knowledge-based Linux+ and LPIC exams.
Can I practice for free?
Yes. Free users get 20 practice questions per day from a fixed sample question pool for each exam, with basic explanations. Pro unlocks the full question bank, complete explanations, and timed mock exams across every Linux bank.
Do Linux certifications expire?
CompTIA Linux+ is valid for three years like other CompTIA certifications, RHCSA is valid for three years, and LPIC-1 and LPIC-2 are valid for five years before you need to recertify.
How much do Linux certification exams cost?
CompTIA Linux+ is around $260 USD, RHCSA is around $500 USD for the standalone exam, and each LPIC exam (two are required for LPIC-1) is roughly $200 USD depending on region.
