Exam Preparation Guide
Purpose of the Exam Preparation Guide
The intent of this guide is to set expectations about the content and the context of the exam and to help candidates prepare for the exam. In this guide, you will find recommended HP training courses, reference and study material to help you achieve a successful passing score.
Studies conducted by HP and Prometric show that a combination of course attendance and self-study maximizes the likelihood of passing the exam on the first attempt.
Beta Exams
What is a beta exam?
A beta exam allows us to test the integrity of the exam before we release it. After beta candidates take the exam, we analyze the results and comments to establish the passing score and improve the exam content, questions, instructions, administration procedures, and so forth.
Benefits to you
• If you pass the beta exam, your score is valid and you do not need to take the final version of the exam. Passing this exam meets one of the elective requirements for obtaining the Accredited Systems Engineer (ASE) Level 2
certification under the NonStop Systems track of the HP Certified Professional (HPCP) Program as well as a NonStop Certified System Engineer (CSE) elective requirement.
• If you are thinking about taking the exam in the near future, you may want
to take the beta exam now to review and become familiar with its content. During the beta exam, you see all the questions in the exam pool. In the final exam, you see only selected questions from the pool.
• If you do not pass the beta exam, you can become familiar with the areas where you are skilled and the areas where you need to study. You then have a better chance of passing the exam the next time.
