The exam typically consists of 125 questions, with a 4-hour time limit. Answers are scored automatically, and the minimum passing score is set at 70%. Candidates who achieve the passing score are awarded the CEH credential and receive a digital badge and a printed certificate.
Prerequisites and Eligibility
EC-Council specifies three primary paths to eligibility: self-study, instructor-led training, and formal education. Self-study candidates must complete a minimum of 20 hours of training, which includes an approved CEH prep course and a 20-hour lab experience. Instructor-led candidates receive a structured training program that typically spans 28 hours, with additional lab time. Formal education candidates may qualify if they hold a relevant bachelor’s or master’s degree and can provide proof of experience or coursework that aligns with CEH content.
Preparation and Training
Official Training Resources
EC-Council offers a suite of official training materials, including e-learning modules, instructor-led courses, and laboratory environments. The labs provide virtual machines and network topologies that simulate real-world attack scenarios, allowing candidates to practice skills such as vulnerability scanning, exploitation, and post-exploitation techniques. These resources are regularly updated to incorporate new vulnerabilities, tools, and defensive strategies.
Third-Party Study Materials
Numerous independent publishers produce CEH study guides, practice exams, and video tutorials. These materials often supplement official resources by offering alternative explanations, case studies, and additional practice questions. Candidates frequently use a combination of official and third-party resources to gain a broader perspective and reinforce learning.
