About the exam:
The CompTIA Network+ exam includes up to 90 multiple choice questions. You will have 90 minutes to complete the exam and must achieve a score of 720 to pass.
Your CompTIA Network+ certification is good for three years from the day of your exam.
You can participate in a number of activities and training programs, including higher certifications, to renew your CompTIA A+ certification. Collect at least 20 Continuing Education Units (CEUs) in three years, upload them to your certification account, and A+ will automatically renew.
