Linux was born in 199 1 year1October, and has a history of more than 20 years. Linux is a set of free full-featured UNIX software. The following are my answers to the frequently asked questions of Red Hat certified engineers. Welcome for your reference!

What impact does the release of Red Hat Enterprise Linux 3 have on the certified engineer course of Red Hat and other courses provided by Red Hat Company?

With the release of Red Hat enterprise Linux 3, Red Hat and its training partners will begin to use it for training courses and certification examinations of Red Hat, but it will be carried out step by step in different places and at different times. From June 5438+February 1, 2003, all Red Hat certified engineer courses in the United States will begin to use Red Hat Linux.

Is the red hat registered engineer operation exam an open-book exam?

No, the red hat registered engineer operation exam is a closed-book exam. Candidates are not allowed to bring any notes or reference materials except the materials distributed with the red hat operating system in the red hat exam. Most standardized exams (including most IT certification exams) are closed-book exams.

I heard that the Red Hat registered engineer exam is based on practical ability. What is the basis? Based on practical operation ability? What about certification or exams?

The examinations for certified engineers and certified technicians of Red Hat are mainly based on practical operation ability, which is mainly manifested in the following two aspects: First, we examine the true ability of candidates, who need to successfully complete all installation, configuration, troubleshooting and maintenance tasks. These tasks are similar to those that a system administrator must complete. Secondly, we will objectively and testably evaluate the ability of candidates to complete these tasks by evaluating whether the system executes the instructions according to the regulations.

Why did Red Hat decide to take the Red Hat Certified Engineer and Red Hat Certified Technician exams based on the actual operation ability?

There is only one good reason why we design the certification of Red Hat certified engineer as an examination based on practical operation ability: quality. We hope that the certification of Red Hat Certified Engineer is a serious and important certification qualification examination, which can examine candidates' practical skills and be a way far better than other operating system certifications in measuring candidates' real ability. When we launched the certification of Red Hat Certified Technician on June 5438+ 10, 2003, the goal was the same, and we felt that the Red Hat Certified Engineer had proved the value of this method to people.

Linux professionals need a kind of certification that they admire, and they know it is hard to come by. When recruiting Red Hat certified engineers or technicians, company bosses need to have enough confidence in them and believe that they have the skills and qualifications needed to complete key tasks by managing the Red Hat system. Consulting companies, VAR and distributors who employ Red Hat certified engineers and technicians can better serve their customers. At the same time, Red Hat certified engineers themselves will be more confident and achieve greater success when implementing Linux system for customers or companies.

What's the difference between a red hat certified technician and a red hat certified engineer?

Red hat certified technicians have the technician level skills needed to install, connect, configure and manage the new Red Hat system in the existing work network. He/she can manage the core system of all systems, whether it is workstations, servers, network devices or other types of systems. Red Hat certification engineer not only has these skills that a red hat certification technician should have, but also can provide network services and security configuration for servers running the red hat operating system.

For more detailed information about the skills of Red Hat Certified Engineers and Red Hat Certified Technicians, please refer to our Red Hat Certified Engineers Program website and exam guide.

Since the certification of red hat certified engineer includes the skills that red hat certified technician should master, can red hat certified engineer be certified by red hat certified technician if he fails the exam?

Of course it's possible. When taking the red hat certified engineer exam, the skills of the red hat certified technician are only part of the content of the red hat certified engineer. If you don't have the skills of Red Hat Certified Technician, you can't pass the Red Hat Certified Engineer exam, because the Red Hat Certified Engineer must be able to handle all the work that the Red Hat Certified Technician can handle, or even more. For Red Hat certified technician, he/she must master certain skills. Without these skills, it is impossible to pass the Red Hat Certified Technician or Red Hat Certified Engineer exam. For certified red hat engineers, there are other skills that must be mastered. If he/she doesn't have these skills, he/she will never be qualified as a certified red hat engineer. If the candidates who take the certification examination of Red Hat Certified Engineer do not have the skills that Red Hat Certified Engineer should have, but fully prove that they have the skills that Red Hat Certified Engineer should have in the examination, they can be certified as Red Hat Certified Technicians.

What are the contents of the red hat registered engineer exam? What must I do to pass the red hat certified engineer exam?

With the launch of Red Hat Enterprise Linux 3, the structure of Red Hat Certified Engineer Examination has changed accordingly. At present, the Red Hat Registered Engineer Examination consists of two parts:

Part I: Troubleshooting and System Maintenance (2.5 hours)

Part II: Installation and Configuration (3 hours)

In order to obtain the certification of Red Hat Certified Engineer, all candidates must complete all necessary troubleshooting and system maintenance problems. In the first part, each candidate must get at least 80 points, and at the same time, in the installation and configuration part, the projects related to Red Hat certified engineers and Red Hat certified technicians must get at least 70 points.

In the exam of Red Hat Linux 9 and before, the exam structure of Red Hat Certified Engineer is as follows:

Part I: Troubleshooting (2.5 hours)

Part II: Multiple Choice (1 hour)

Part III: Installation and Configuration (2.5 hours)

In the Red Hat version 5.2 ~ 7.3 exam, to pass the Red Hat Certified Engineer exam, the average score of the candidates in three parts needs to reach 80 points, and the score in each part should not be less than 50 points. In the version 8.0 and version 9 exams, candidates should not only meet the above requirements, but also complete all required troubleshooting problems, and in the installation and configuration part, the projects related to Red Hat certified technicians and Red Hat certified engineers should get at least 70 points.

Why did Red Hat remove multiple-choice questions in the examination of Red Hat Enterprise Linux 3 and higher?

Red Hat Company has held the Red Hat Registered Engineer Examination for nearly five years. After so many years of examination, we found that according to the actual performance, it may be better to use the time required for candidates to answer multiple-choice questions to complete the task. According to the analysis of statistical data, the results also show that the part based on practical operation ability in the exam is much more effective than the multiple-choice part.

Why does Red Hat still keep multiple-choice questions in the Red Hat Linux 9 exam still held in some places?

Red hat certification is closely related to the operating system passed by candidates. If the multiple-choice part in the Red Hat Linux 9 exam is removed, it will lead to the situation that some 9th edition certificate winners need different conditions to obtain the same certification as others.

Why have the certification requirements changed in versions 7.3 ~ 8.0?

Since version 8.0, the certification requirements have been adjusted. This is to prepare for the certification of Red Hat certification technicians to be launched within a few months after the release of the Linux version of Red Hat. After re-adjustment, the Red Hat Certified Engineer Examination conducted a more comprehensive assessment of a wider range of skills. In order to ensure that candidates who have passed the certification of Red Hat Certified Engineer can fully prove that they have network services and security skills related to qualification certificates, we need to add new requirements. These new requirements are the difference between certified technicians and certified engineers.

Does Red Hat Company have statistics on the certification operation examination of Red Hat certified engineers?

From 1999 to 1, Red Hat Company and its certified training partners have provided thousands of candidates with the Red Hat Certified Engineer Examination in a unified and equivalent way in training classes around the world.

Within three weeks after the release of each new retail version (*** 10 version: 5.2, 6.0, 6.2, 7.0, 7.01,7.2, 7.3, 8.0, 9), Red Hat Company can complete the Red Hat Certified Engineer.

The average failure rate of Red Hat Certified Engineer certification has been fluctuating from 42% to 37% every quarter since it was first introduced.

Among the candidates who failed the certification, more than 75% scored very high in the multiple-choice part (above 85 points). This fact fully proves that although candidates can get high marks in multiple-choice questions, it is still difficult to perform real basic system management tasks-server setup and/or debugging and troubleshooting.

When will the exam results be announced?

We will send you the test results of Red Hat certified engineers by email within 3 working days in the United States, but only if you provide accurate contact information. Unfortunately, some mail servers mistake these messages for spam and filter them into spam boxes. Candidates who have not received the test results within 3 working days in the United States should go to www.redhat.com/training/certification/comments.html. through the website.

Please don't ask or expect your red hat certified engineer to make a test report form and inform you of the test results informally on the day of the test. They are not allowed to issue informal notices.

When can I get the certificate?

For your convenience, we will issue you an electronic certificate, which will be attached directly to your notification email.

Why doesn't Red Hat issue a paper certificate?

E-cert has several advantages. First of all, you can send a certificate while processing the results, so that candidates who receive the certificate can use it immediately. Secondly, the holder can print multiple electronic certificates, which is convenient for families and companies to use. Third, e-cert is easier to be replaced at a faster speed. And they are often more economical and effective, which will undoubtedly bring great benefits to users.

More importantly, neither paper certificate nor electronic certificate is the most valuable evidence provided by Red Hat. Verified by www.redhat.com/training/certification/verify/ website is a different response of Red Hat. Anyone can make a paper certificate with a computer and an appropriate drawing program. Having a' unique certificate number' that can be verified by a certification body (here refers to Red Hat) is very authoritative, reliable and of unlimited value.

How often can I take the Red Hat Certified Engineer exam again?

You can take or re-take the Red Hat Certified Engineer exam according to your own wishes. You must retake all the Red Hat Certified Engineer exams. No parts are given.

Can Red Hat Certified Engineer take the exam by rote?

You can't. Red hat advises you not to recite. The red hat certification engineer exam is very different from most IT certification exams. You may be able to memorize the multiple-choice exam, but it is impossible to pass the test based on actual operation ability and in the actual system. Unless? Bad memory? In this case, it means gaining real experience and actual combat time.

How to teach yourself to take the red hat registered engineer exam? Are there any books recommended by Red Hat or self-study books and CDs on the market at present?

Red Hat has not approved or authorized any organization to publish any specific examination series for Red Hat certified engineers or launch any related self-study programs. We don't have any suggestions for such books or projects, because we don't have time to evaluate or measure their effects, and we won't agree to anything until we determine their effects. Red Hat Company provides RHCE exam preparation guide for those who decide to prepare for the exam themselves. This is a very general guide, not a comprehensive or thorough self-study plan. Only suitable for people who have a deep knowledge of user and system management.

Does Red Hat have any suggestions on how to prepare for the certification examination of Red Hat certified engineers?

For students who are interested in actively preparing for the exam of Red Hat Registered Engineer and Registered Technician, Red Hat Company puts forward the following suggestions: 1) Participating in advanced practical training specially designed for the skills examined in the exam should be similar to the courses provided by Red Hat Company; 2) Get practical experience about Linux system management; 3) Before deciding to take the exam, make sure that you have the necessary network skills.

Both Red Hat certified engineers and Red Hat certified technicians are examining candidates' professional system management ability, which can not be obtained by training alone. Therefore, in addition to participating in advanced practical training, you should also have practical experience, preferably work experience. Good training is an important factor for success, but other factors depend on individuals.

No matter which way you prepare for the exam, we recommend that you use our exam guide instead of third-party materials or other second-hand materials to study and contact. The red hat exam guide is an authoritative guide to introduce the content of the red hat exam.

How long is the validity period of Red Hat certified engineer certification?

Although the research shows that Red Hat certified engineers who specialize in their own specialties will improve their skills simultaneously with the release of the new version of Red Hat Linux operating system technology, for Red Hat companies, a principle must be adhered to, which can determine whether the certificate of a Red Hat certified engineer or technician is valid. Therefore, the certification service provided by the certification center for all Red Hat certification engineers will always include which version of the certificate has been obtained and whether the certificate is still valid or no longer valid.

Now, the validity period of all Red Hat certified engineers and technicians has been formally linked to the specific version of enterprise products that have been launched through commercial channels at the time of certification. At the same time, this version will remain valid until Red Hat Company launches an important version of enterprise products. The certification certificate of Red Hat Enterprise Linux 3 will be regarded as valid certification before Red Hat Enterprise Linux 5 goes online.

The certified engineer certificate of Red Hat Linux 7.3 or earlier will be regarded as a valid certificate before the launch of Red Hat Enterprise Linux 4. All certified engineers and technicians certified by Red Hat Linux 8.0 and 9 are valid before the launch of Red Hat Linux 5. You can continue to verify the validity of the certificate of Red Hat Certified Engineer through the certification center.

With the launch of Red Hat Enterprise Linux 3, what impact has it had on the certification of Red Hat Linux?

Because all the certificates certified by Red Hat Linux are closely related to a specific version of Red Hat enterprise Linux, the above principles are still valid.

What are the benefits of passing the red hat certification?

We interviewed and investigated the certified engineers of Red Hat independently. The survey results confirmed our long-standing understanding that the certification based on practical operation ability is more meaningful to confirm Certification staff's working ability. Compared with other types of certification, the certification of Red Hat certified engineer has been given a higher status. Whether for individuals, companies or managers, this certification has many benefits:

Confidence and ability: Red Hat certified engineers have more information about their skills and are better at building and managing Linux servers. In this way, their work quality and professional skills have been greatly improved, their work performance in the company is better, they can accept more challenging tasks, and they will also be recognized by everyone.

Occupation: The interviewed Red Hat certified engineers also told us that within three months after being certified by Red Hat certified engineers, they got one or more of the following opportunities: a new job, salary increase, promotion, assignment of more responsibilities, being appointed as a team leader or management position, and improving their status and/or reputation among employees.

Income: A recent independent survey conducted by computer dealer news and certification magazine shows that engineers who pass the red hat certification can get higher wages. For more information about these surveys, please click the salary survey link.

What benefits does Red Hat Company provide directly to Red Hat certified engineers? How long will these benefits last?

Red Hat Certification Center provides verification services for all red hat certification engineers. The certified red hat engineer or his company or customer can verify whether this person has really passed the certification and the accurate version of the exam he has passed by inputting a 15-digit code of the certified red hat engineer. We will provide this service for a long time. If the certified version of Red Hat Certified Engineer is no longer valid, the verification record will be displayed? No longer valid? . Red Hat certified engineers also enjoy the privilege of directly accessing the RHCE connection website. On this website, Red Hat certified engineers can get preferential quotations, discounts and benefits, as well as technical updates and resource access. Access to RHCE connection and its services is a value-added service provided by Red Hat Company, which has its own discretion.

At present, the principle of accessing RHCE connection is that only red certified engineers with valid certificates can access the website. Other benefits of Red Hat Certified Engineer certification (such as the cooperation plan between Red Hat and your company) may require you to obtain the latest major version of Red Hat Certified Engineer certification, or may require you to obtain certification more frequently than the personal principles in Red Hat Global Training Service Plan. This is to ensure that Red Hat's cooperative companies can adopt higher practical standards. Of course, it depends on whether you or your company can keep up with the qualification requirements of these projects. ;
