IT certification of sentiment: the certificate and ability in the end who is more important?
Certification is very important? Some say: “That, of course, is not how to prove their level of certification?” Others say: “not necessarily the actual capacity of the most important.”
Both answers are probably right, but incomplete. On this topic, I would talk about according to their own learning experiences and understanding of the views of the certification, for your reference:
1, the certificate of true and false
Broadly speaking, at this stage of employment, the certificate is still important, the certificate is the ability to abstract reflection of the learning process and results proved that without the certificate, you can not prove that! Maybe you really are strong, no matter how good you say , others my heart I will not see you too, Just think, one holding a high school graduation certificate and a master’s degree candidates graduate student to work with a technology-based, others more fancy Who? certificate must exist a certain historical period , we can not deny the importance of the certificate, as the same as university diplomas issued by the State Education Commission.
Certification is narrow, such as network technologies such as professional certification such as MCSE, CCIE, CCNP, etc., we must be clear what brought about such a certification, what? From the firm’s point of view, is undoubtedly of interest to maximize the introduction of Networking Academy, training, certification bodies, the most basic intention of these strategies is to simply promote the visibility of their products and expand market size, when they come out from the university college students who served as XX in the XX business office, business, once there is demand, his first thought was XX vendor network products (of course, rule out other external factors, complete departure from the individual’s original idea), he became the most powerful factory sales. Up from a personal point of view is that no doubt would like to improve their technical level, while increasing income to improve their living conditions for themselves to find a satisfactory job! Revenue base, naturally do not have to say much more. However, our technology is to improve it? On the surface, yes! You say that CCIE and CCNA, which enhanced technical capabilities? Needless to say: CCIE! But the CCIE network technology is really an expert? I see not, especially now, the examination of water I do not have to say, we all know. As long as the network technology have a certain interest in the same time, the people will be willing to spend IE! Our company had a brother, I took the test three times, only narrowly passed, it took two to three thousand dollars, even more unfortunately, are getting the dream of a certificate of employment on the road is not so bon voyage. The most important thing is do not forget, we are on the application of network technology, not development, is to put other people’s ideas by practical application of the physical environment go! You heard, driving F-22 pilots flying specialists? Maybe he is the future, but as long to open the aircraft, there is no person that he is an expert. Most people who go into space called the astronauts. Designed by others a knock on the side of the command to re-engineer, at most, to know the structure and forwarding packets principle one could call specialists? Some far-fetched. Cisco 642-436
At the same time, the network application is from a single business model to a multi-business model to expand, has just passed Routing & Switching CCIE’s brother
Brother, do you understand speech? Do you understand the media? Do you understand safe? You know Unix, Linux, Oracle do? Do not know!, But users have such a demand, how should I do? Learn 呀. Do not think they have been practicing to the highest state of network technology, we need to learn many things in too much.
2, capacity is the most important
On this topic, I can give an example to explain that in 2000 I passed the HCSE, but to get the certificate the first 6 days, I went to do a special CISCO systems integrator, to work the first day, to the company’s bench has not yet firmly secured, the boss sent me sent to a company, said it was exactly one item, very anxious to be resolved quickly. I am also a person to go. Really, really do not mind the end of that time, the heart speak, is over, not even familiar with the products, no chance! That’s no way Yeah, bite the bullet and boarded the plane.
Who knows to which see, I dumbfounded, almost no paralysis continues, routers, switches, self-suffice it to say, there are seven sets PIX firewall, a lot of wireless AP, IP phone, what is there … …. Do not say these things I’ve seen have not even heard of hearing. How to do this time? Tell customers that I Gaobu Ding? Called the boss that I learned just routing switching, the other could not find? Can you? Can not. So what do, do it! I have a little calm and a bit and become a deep breath and began to examine the user the current network conditions, ask customer demand, which know the trouble is still behind the demand of customers is simply too much: the headquarters and other Division through firewalls VPN, through the GRE tunnel using the OSPF routing protocol to achieve dynamic routing at the same time to enable IPsec to encrypt data, wireless AP on the division of VLAN, IP phones and PSTN interworking … … I Kuangyun!
I carefully write notes to the existing network equipment configuration Copy down the new device model, name written down. Back to the hotel looked just write something really very complicated, finally sorted out the structured. But time is pressing, I can not neglect, drill into the interconnect line, crazy look for materials, to find documents, in conjunction with their theoretical knowledge, sorting out the project implementation plan! Behind the things that is not to say, the natural hardships and difficulty, in the not solve the problem, I always sky nonsense, but always saved the day. Half a month later, the project finally completed! Customer satisfaction survey form filled out is: very satisfied. Acceptance of course, no problem (of course also have my Huyou effort, ha ha), but I have physically and mentally exhausted, I am thin. To get acceptance in the report, I was lying in bed in the hotel a myriad of thoughts: I have the certification exam brought me what? An easy? No, just a learning opportunity.
Said here, some would say: If you do not have the certificate, others do not give you the opportunity to learn! Yes, but it is also precisely that question: the certificate is only recruited to work in your work the moment, other times worthless! certification exam that manufacturers not important, it is important you do not really understand the technology, can solve the problem.
Today I have learned a lot of things other than certification. In addition, the network technology is moving towards international standardization, each device manufacturers must comply with these standards! So for us to seriously study the technology is the most important of these standards, rather than blindly pursuing the vendor certification .
For access to a manufacturer-certified engineers, you can not exclude other manufacturers of equipment, for example, you are xx-certified engineer, if you are CISCO network equipment such as a world-class manufacturing things will not use, would not be too sorry it? If you are a CISCO certified engineer, much less supercilious.
Another point worthy of our attention has been the proliferation of network technology certification, many college graduates have gotten into the certified tide of years, is bound to result in supply exceeding demand in one day, so many people crowded into a corridor go rush of a share, then we have a value? So, I advise those brothers and sisters in computer science, network technology, certification of other professional people that there should be considered a shortcut, but not necessarily for you, and should strengthen the basic knowledge of learning, improve thinking, such as learning the language as far as possible to engage in the development, can not go to test, what kind of certification is needed. The pressure of employment, a positive hit our generation, those who wanted to test certification exam has not yet, or are being test, and ask you to consider carefully, certification, after he was in the end give you what?

From the basic requirements of view: CCNA study time is short
The most people, CCNA involved in the foundation of network knowledge and equipment, but also the support of CISCO equipment, learning cycle in about 1-3 months or so
MCSE daily use more approachable, and can be achieved most of its stand-alone certification exam requirements, the learning cycle of seven subjects for at least 3-6 months.
From the learning costs of view: CCNA low-cost
CCNA only involves an examination, the examination fee at 20 dollars, if the self-study, then, together with books and teaching materials cost no more than 30 U.S. dollars;
While there are seven exams MCSE, optical examination fees in respect of 45 U.S. dollars.
From the direction of view of employment: CCNA are highly specialized
CCNA employment direction system integration, network installation and maintenance and so on debugging.
MCSE suitable positions, there are system administrators, network administrators, and so on.
From the work content perspective: CCNA required hands-on capacity
CCNA is a simple CISCO based network equipment debugging and knowledge;
MCSE is for the Windows environment, network, system management, configuration, maintenance;
The general public, we recommend students for certification in terms of need, you can choose CCNA, time is short, quick, cost-effective.
