In Cisco Certification, CCNA is the primary technical certification in network. After passing CCNA, it means that you have already started in network. There will also be certain advantages in employment interview, because CCNA Certification indicates that the holder has the basic knowledge and operating skills in the network. Therefore, it is necessary to pass CCNA Certification if you want to engage in relevant work. But how can I quickly pass CCNA Certification Exam?
Step 1: familiarize yourself with the study guide
The original textbook of CCNA is in English. At the beginning of reading, for students without foundation, it may totally make no sense. At this time, perseverance is required. Read the parts that are easily understood first, and then you may understand the rest slowly after reading it for 3 times or more.
Step 2: learning focus
1. Network foundation
The most important thing to learn CCNA is to master the network foundation, because other routing protocols may not be used for a long time, and only the basic knowledge of the network will be remembered for a lifetime. The definitions of the 7-layer model and the 3-layer model of the network and the relationship between them should be kept in mind, because this is an easy question to ask during the interview.
2. Routing protocol
In CCNA routing protocol, the configuration methods of RIP, EIGRP, OSPF and other three types of routing protocols are introduced. To be honest, if you are not engaged in large-scale computer room or participate in large-scale network construction or maintenance, these knowledge may not be used for a lifetime, but these knowledge is the foundation for large-scale network construction, so you should master it carefully.
3. Experiment The experiments of CCNA are relatively simple (compared with the later experiments of CCNP, they will be more complicated), so you can easily master them through an experimental guide and
simulator. Note that more experiments must be done, and the routing configuration commands must be memorized, so that the commands can be input line by line without thinking when touching the keyboard. Because in actual work, the time reserved for network maintenance is usually very short, and routing configuration needs to be carried out in a very short time, so it requires deep skills.
4. TCP / IP protocol and sub-net division
The understanding of TCP / IP protocol is also very important. This part of the content is inseparable from daily life. For example, commonly used routers, switches, servers, etc. have corresponding positions in the protocol. In terms of fault handling, TCP / IP protocol can quickly help define the problem.
The sub-net division may be difficult for beginners to master. There will be corresponding problem-solving skills in the textbook. If you master the skills and practice more, you can still firmly master them. Moreover, it is very useful to learn the sub-net division. If you do maintenance work in the computer room, you need to assign IP network segments to customers, and you need to practice the sub-net division almost every day.
Step 3: Examination
Domestic examinee are best at the examination. On the premise that the CCNA examination has a question bank, most students can easily pass the examination. Because the question bank is in English, it may be necessary to look up the dictionary when learning the question bank for the first few times. When you memorize the question bank, you can take the exam. I believe you will get high scores.
Although there are only three simple steps, the middle step really needs a lot of thought. After all, we must study hard and there is no other way to reach the goal in one step. So study hard and make progress every day~
