Yes. You can start EX200 practice and flashcards free without creating an account. A free account keeps your progress, and the full bank (300+ questions) unlocks with a subscription.
They cover all 10 domains of the EX200 exam: Understand and use essential tools (14%), Operate running systems (14%), Configure local storage (14%), Create and configure file systems (10%), Deploy, configure, and maintain systems (10%), Manage basic networking (10%), Manage security (10%), Create, delete, and modify local user accounts (9%), Create simple shell scripts (5%), Manage containers (4%). Each section is weighted in the same proportion as the real exam, so nothing high-value is buried.
The EX200 exam has approximately 60 questions in 180 minutes, with a passing score of 70%. Use the practice questions to confirm you are consistently above that line before booking the real exam.
Study in short, spaced sessions: a card you have not seen for two days is worth more than a card you reread immediately. Filter by Understand and use essential tools first, then mix domains so you practise identifying the topic before recalling the definition.
They are the recall half of preparation. Pair the cards with practice questions and at least one timed practice exam — candidates who only review cards usually recognise terms but miss scenario questions.
