JDMurray said: The CEH Exam Blueprint 4.0 was launched on Jan 1, 2021 as the replacement for CEH Exam Blueprint 3.0. The "312-50: Certified Ethical Hacker Exam" has 4.0 blueprint items added to it, so you can't choose between taking a 3.0 and a 4.0 exam when you register for the exam. The 312-50 exam itself has no versioning anymore and only the certification training changes by the blueprint release. This is how CompTIA, ISACA, (ISC)2, etc. have done their exams and training for years. I would suggest that you include the blueprint 4.0 items in your CEH studies.
