Beta Exam HP1-764

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.

NonStop Guardian Architecture – Level 2

Timeframe

The exam (and administration time) takes approximately 4 hours or less. This estimate does not include the time needed to take the survey, which averages ten
to 15 minutes.

About the Beta Exam

This exam contains approximately 187 questions, which you are required to answer. During the beta test phase, candidates are expected to answer ALL items within the exam item pool. This is a closed book exam. No reference materials are allowed.

A passing score is based on analysis of beta exam results. You will receive your final score after analysis of the beta exam is complete.

Tutorial

Before you begin the exam, you can take a tutorial to familiarize yourself with the details of taking online Prometric exams. If you have not taken an online
Prometric exam, you are encouraged to take this tutorial. It will help you take the exam more efficiently. Time for taking the tutorial (approximately 10 to 15
minutes) is not counted against the time you have to take the exam.

Survey and Comments on the Exam

Before the taking the exam, you will see survey questions. The survey has been designed to assist the exam development team in accurately profiling test results and in improving future exams. Your honest responses will assist the exam team
in properly tailoring this exam to the appropriate target audience.

After you have completed the exam, you can make comments on the exam questions including their accuracy and appropriateness to audience.

Note that one to five years’ experience or more is highly recommended for ASE certification. “Hands on” experience with the NonStop S-series system is essential.

Exam Details

NonStop Guardian Architecture is a beta exam. This means that you will see all the questions in the exam pool. During the final “live” exam, you will see only those items that remain after the beta test.

You will receive a score report with your results after beta testing is complete
which you can use to identify areas of strength and learn about areas to improve upon for the live exam.

Please allow 3-5 months, after you have taken the beta exam, to receive your score report.

If you do not pass the beta exam, refer to your percentages for each core competency shown on your score sheet. Use these results to guide you in areas where you need to study or review more than other competencies.
