As a former code farmer, Xiaoshuo is one. I often meet some students who want to do research. They say they want to work in the computer industry. Do you want to do research? Are testimonials useful?
In my opinion, there are really too many certificates in the computer industry, but not many are really useful. Today I will talk to you about two or three things about computer certificates. Which certificates are recommended to take, and which ones do not need to waste time to take the test. After reading this article, you will be enlightened . It doesn't matter if you don't understand it now, save it first, maybe your children will use it in the future.
1. National computer grade certificate
This is not too necessary to test ah brothers. Although the name is very big, it is also undertaken by the Ministry of Education. But I personally prefer that the grade certificate is still given to non-computer majors.
Especially the first-level certificate and the second-level certificate are almost at the level of junior high school students. The third-level certificate and the fourth-level certificate are available for those who are interested, but the gold content is really average. For enterprises, basically no one has recognized this. For fresh graduates, enterprises can use the third-level or fourth-level certificates to know that you did not waste time during your studies, which is almost the role.
Essentially, you can only comfort yourself with "something is better than nothing" . Therefore, if you prepare for the national computer grade certificate, the time you invest can hardly be exchanged for the return, so it is not necessary. Of course, for non-computer majors, it is a choice to learn some computer professional knowledge by taking a second-level certificate. After all, the content is very basic and simple, and it is still very feasible as an enlightenment study for non-computer majors.
2. Computer technology and software [professional technical qualification examination] (commonly known as soft examination)
The soft test is undertaken by the Ministry of Industry and Information Technology, so it is relatively professional. At present, domestic public institutions and state-owned enterprises all recognize this certificate when evaluating and hiring professional titles. Of course, having this certificate only means that you have a chance to be hired, and the specifics also depend on the ratio of the number of units. But no, you can't get hired.
I suggest that students who are interested in developing into public institutions or state-owned enterprises can take a soft test title certificate when they have time. I personally recommend taking the intermediate level directly, because the difficulty of the intermediate level is moderate , and when you have an intermediate level certificate, the unit can hire you as an intermediate level or a primary level. It's equivalent to taking an exam directly. My brother took the intermediate exam himself, and he prepared for about a month.
The official textbooks are really thick and have a lot of content, but in fact there are only a few key points, just do more real questions over the years to sort out the ideas and memorize the key points . In fact, the intermediate level covers a lot of relevant certificates, and there are many types. You can choose according to your interests.
Let me show you what my brother’s mid-level professional title certificate looks like. At present, my brother is also hired as an engineer (intermediate professional title) in his work unit. At present, there is no plan to take the senior professional title test, after all, it will not be used for a long time.
One thing to mention, the [system integration project management engineer] my brother took the exam will involve some bidding content, minimum engineering quantity calculation problems, and of course some computer knowledge questions, etc. I personally think that this certificate will not be too difficult for non-professional candidates . If you are a student majoring in network or communication, it is recommended to take the intermediate title of [Network Engineer]. Try to match up with your major.
It is recommended to choose one in the middle class. At present, the recruitment of public institutions in some areas even directly restricts graduate students in computer science or obtains intermediate professional titles in computer science . So it is quite meaningful to take the intermediate test, but it is completely unnecessary to take the primary test, which is really a waste of time.

3. Red Hat Certification
Students who are interested in Linux and want to develop in this area in the future are highly recommended to take the [Red Hat Certification]. This certification is recognized globally. I think the main reason is related to their examination methods. Red Hat certification is mainly to examine practical ability . It can be clearly said that if you are not familiar with the operation, it is more difficult to pass the exam. Due to its strong practicality and high degree of fit with enterprises, Red Hat certification is recognized by many enterprises.
Red Hat certification is divided into three levels, Red Hat Certified Technician (RHCSA, equivalent to junior), [Red Hat Certified Engineer] (RHCE, equivalent to intermediate) and Red Hat Certified Architect (RHCA, equivalent to advanced).
If you want to find a Linux-related job, you can't just pass the primary RHCSA exam. Those commands are too simple and basic. According to the current job market situation, a mid-level RHCE is a must. As for the overall difficulty of RHCA, it needs more systematic and in-depth research and learning to win. Therefore, I personally suggest targeting RHCE .
We all know that the courses in universities now generally contain some old content, and there are basically few schools that specialize in Linux courses. Therefore, most students who learn Linux are basically self-taught, so students with strong self-learning ability need not be mentioned. But for many students with average self-learning ability, I think listening to online classes is more helpful. Of course, I think the self-study difficulty of Red Hat certification will be slightly lower than that of Huawei certification. But students who like to listen to the teacher's lecture summary are also recommended to listen to the class.
Some students may ask what courses to watch, I recommend one that I have heard and feels good. Students who are interested in Red Hat certification suggest to click the link below. Through courses and practical training, it can help you learn and understand Linux-related knowledge more quickly. It is much better than memorizing by rote. The course content includes find and grep commands, tar archive and compression, adhoc usage and host list, command and shell command push, playbook syntax and structure, small script examples and shooting errors, setup indicators and debug debugging, vault data file encryption, etc.
4. Huawei certification
If you plan to rely on the network in the future, the gold content of Huawei certification is very good . Domestic recognition of Huawei certification is also very high. The positions that match the certificate are mainly network engineers, [system integration engineers] or system [operation and maintenance engineers].
Huawei certification is mainly divided into three levels, [hcia], hcip, hcie, the official explanation is as follows:
HCIA : Huawei Certified ICT Associate (Huawei Certified ICT Engineer)
HCIP : Huawei Certified ICT Professional (Huawei Certified ICT Senior Engineer)
HCIE : Huawei Certified ICT Expert (Huawei Certified ICT Expert)
In fact, in terms of levels, hcia is equivalent to the elementary level we mentioned earlier, hcip is equivalent to intermediate level, and hcie is advanced level. It is really useless to get a hcia to find a job in a company now. However, HCIE is relatively difficult, and it is not suitable as the choice for the initial research, and the price is also expensive. Therefore, I suggest that students who are interested in taking the Huawei certification test take a mid-level hcip. After the hcip is obtained, as the knowledge system becomes more complete, whether to improve themselves at work, or to sprint for hcie, such Route planning is more reasonable.
Relatively speaking, I think that Huawei certification is network-related knowledge after all, and its self-study is more difficult than the Linux knowledge of Red Hat certification. Red Hat certification is a practical type. As long as you actually do it in the learning process, it will often be more profound. However, Huawei certification is still recommended to study in lectures, because some knowledge is still abstract.
Some students who want to know about Huawei certification suggest poking this to take a look at the online class. It is really much more efficient to learn with a teacher than to read a book by yourself. Students who are interested in the Internet can click over to find out.
5. [Cisco Certification]
Cisco certification is also very valuable, mainly for students in the network direction. The difference from Huawei certification lies in the product. However, it is worth mentioning that the universality of Cisco certification in China is not as good as that of Huawei certification, and its main job market is still mainly abroad. Therefore, students who are interested in the direction of network engineers can choose Huawei certification or Cisco certification according to their future employment plans.
Cisco certification has CCNA, CCDA, CCNP, CCDP, CCSP, CCIP, CCVP, CCIE (also divided into routing and switching; voice; storage network; security; telecom operators) and other different levels, different content, different directions Among the various certifications, CCNA, CCNP, and routing and switching CCIE are the most commonly used and the social demand is relatively large.
Cisco Certified Internetwork Expert Cisco Certified Internetwork Expert is regarded as the top CCIE certification in the global Internetworking field. This certification mainly provides engineers with the professional knowledge needed to control Cisco equipment in today's rapidly changing network environment.
At present, there are mainly three types of CCNA, CCNP, and CCIE that are in relatively large demand. The three categories correspond to the elementary, intermediate, and advanced levels we mentioned many times before. Although the official name is expert level, in fact it is advanced in analogy to the past.
Then there is no doubt that Brother Na's recommendation must be to go directly to the intermediate level. Because the difficulty of the CCNA exam is too basic, it is not very necessary for computer science students. Of course, for students with relatively weak foundations, I think it is also a good thing to take the CCNA test to consolidate their knowledge. For self-study, CCNA can usually be won in about half a month to a month.
CCNP has a higher gold content, and it is also a certificate that companies are willing to look at when recruiting network engineers. The learning intensity is about 1 to 2 months. If you go to the training class, you have to listen to the class for more than half a month, and do the real questions before the exam, and the probability of passing will be quite high.
And CCIE is the most difficult test, if you don't have certain work experience and in-depth understanding of professional knowledge, it is more difficult to pass the test. And this kind of advanced certificate, even if you pass the test as an inexperienced person, the company cannot reuse it for you. The job of the Internet still needs to accumulate knowledge and experience in the work. So in general, it is not recommended to spend a lot of time on CCIE, and it is more recommended to take the CCNP test.
If you sign up for Cisco certification, you can find out about it at the local test center. With some training courses, it will not be too difficult to learn.
Due to time and space constraints, I will talk about these first this time, and I will add other content in the future. Welcome to like and bookmark for future use .
