Examination content and process
Among all kinds of international technical certification systems, RHCE (RED HAT Certified Engineer) certification introduced by Red Hat Company is its biggest difference and value, which emphasizes the performance-based testing method that the examinee actually does during the test, and carries out installation, configuration, debugging, setting up various network environments and practical operation ability tests in full accordance with all kinds of network services really needed on Red Hat LINUX platform.
The whole process of taking the RHCE exam is about six hours, of which about one hour is used to answer technical multiple-choice questions, and the rest time is concentrated on the strength test done by the candidates themselves. Each unit exam is closed, and candidates are forbidden to take notes and copy questions and answers. The topics are all live performances, and candidates must know how to plan, judge and propose solutions in order to pass the exam.
The RHCE certification exam lasts for 6 hours and takes candidates one day. The exam is divided into three parts, including:
1, debugging test); Involving 2 to 4 questions; The examination lasts for 2.5 hours (full mark 100), and its purpose is to test the comprehensive technical ability of candidates.
2. Multiple-choice questions consist of 40 to 50 technical questions, with a duration of 1 hour (full mark 100).
3. The server installation and network service setting test is also a comprehensive technical ability test, lasting 2.5 hours (full mark 100).
In order to pass the exam, candidates must get an average of 80 points in all three parts of the exam, and the score in any part cannot be lower than 50 points. The exam is only held in the Red Hat Certification Training Center, and the price in 2008 was $750. The United States and Canada have established 2 1 training centers. China, Beijing, Shanghai, Guangzhou and Chengdu have also established officially authorized training centers.
Examination fee (latest price in 2009): training+examination fee: 6800 yuan (including original textbooks and examination fee)
The value and employment field of RHCE certificate
RHCE certification is a certification with high gold content in linux industry, which is suitable for Internet architects, security architects, operation and maintenance architects, system integration architects, system engineers, pre-sales engineers and other employment fields.
Analysis of occupational characteristics:
There are obviously fewer managers or developers on Linux platform than on Windows platform, but the demand for Linux technical talents is beyond people's imagination, both at home and abroad. On the one hand, as the IT industry is developing in the direction of Internet and data center, enterprises are seeking to build the whole enterprise informatization foundation on Linux platform. For example, Google had 2 million Linux servers in 2005 alone, and even giants like Microsoft are seeking to acquire Yahoo to maintain the advantages in the new Internet era. In the past two years, Microsoft made its appearance at the global Linuxworld Conference, showing the shock that Linux has brought to the industry.
On the other hand, because the Linux platform is too difficult to get started, it doesn't take a long time to hone or have no professional guidance, and the progress is very slow. The proportion of finished products is much lower than that of talents on Windows platform, especially architects with advanced skills who can provide industry solutions. It is even rarer. At present, many so-called Linux talents just taste some common services under Linux, and illegally use a lot of open source software resources, without being tempered by various technologies in the whole open source industry chain. Many internet companies are still relatively backward in the application of Linux and open source because of the quality of personnel. And even fewer technicians are familiar with UNIX/Linux system and Oracle database.
Demand and present situation of industry talents
At the critical period of domestic Linux development, the bottleneck effect becomes more and more obvious. We are embarrassed to find that professionals in Linux, especially those in localization, are far less than those in Windows-both in quantity and quality.
Regarding the challenge faced by Linux in China, Academician Ni Guangnan once pointed out that talent is everything. With more and better Linux developers, it will promote the popularization of Linux in China. On the contrary, if most developers only know Windows, it will be difficult for Linux to develop.
The application level of Linux in former China still lags behind that in developed countries, mainly because there are not many people familiar with Linux in China, the applications developed on Linux are not rich, and the contribution of Chinese people to Linux is still very small.
With the increasing popularity of Linux in China, the demand for Linux talents in enterprises will continue to heat up, and the performance at the level will be more abundant. For example, in system-level database, message management, Web application, desktop office, embedded development and so on. Linux-related talents can also get 20-30% more salary than Windows-related talents.
The above statement can be verified on the well-known domestic recruitment website www.51job.com. Taking this website as an example, in the recruitment of IT talents in Beijing, two keywords "Windows" and "Linux" were respectively typed. In all the recruitment information in the country, we can see that the demand for talents with the keyword "Windows" is10/34, and the demand for talents with the keyword "Linux" is 1 100. (
