Not once, not twice but as many times as i want. 400-051 practice tests give me the opportunity to rewrite the exams unlimited attempts. I clear the doubts i have and also succeed in the CCIE Collaboration Written Exam certification exam today. I score very good as much as 935 marks at first attempt. I will continue giving mock tests now because i find it very good.
Unlimited attempts for 2 months
