Can you pass the written test by watching CCNA video? Before answering this question, first of all, we know that CCNA is the most basic certification in Cisco certification. At the end of February this year, Cisco certification system was reformed, and CCNA began to combine nine directions. Candidates do not need to choose the direction, just take a 200-301 exam CCNA, which is based on the latest network technology, software development skills and positions, covers a wide range of basic knowledge of the IT profession. It can be said that obtaining CCNA certification is the first step to prepare for it technology career.

Back to "can I pass the written test by watching CCNA video?" This is the problem. In fact, the difficulty of CCNA is not big. Although there are a lot of test contents, they are all basic contents, so it's not difficult to pass the written test by watching the CCNA video. But here's another question. Do you know what video you're going to watch? Is the video you are watching updated? Is it reliable? If you find unreliable video resources, you may make yourself do a lot of useless work.

In fact, after understanding what CCNA needs to learn, you can also find videos targeted. You need to learn the knowledge and skills of installing, configuring and operating small and medium-sized networks, lay the foundation for network, security and automation, master the basic knowledge of network access, IP connection, IP service, security, automation and programmability.

The content of CCNA includes but is not limited to identifying the components of computer network and describing their basic characteristics, and describing Ethernet as TCP/IP network access layer, and describes the operation of the switch, installing the switch and performing the initial configuration, and describes TCP / IP Internet layer, IPv4, its addressing scheme and subnet division, explains host to host communication between switches and routers, identifies and solves common switching network problems and common problems related to IPv4 addressing, describes main functions and addresses of IPv6, configures and verifies basic IPv6 connection, describes static routing operation, advantages and limitations, and explains dynamic routing protocol It also describes the components and terms of open shortest path first (OSPF), the purpose of layer 3 redundancy protocol, the basic concepts of Wan and VPN, the operation of access control list (ACL) and its application in the network, the configuration of Internet access using dynamic host configuration protocol (DHCP) client, and the network address forwarding on Cisco router This paper introduces the concepts of network programmability and software defined network (SDN), and intelligent network management solutions, such as Cisco DNA center? Software defined access (sd-access) and software defined wide area network (sd-wan).

In fact, watching the CCNA video is more likely to pass the written test.

Can I take the CCNP certificate directly? As we all know, Cisco certification is divided into three levels. Some candidates who took the Cisco certificate asked me whether I can take the CCNP directly instead of taking the CCNA. Next, I will analyze whether I can take the CCNP directly.

CCNP certification overview

In fact, CCNP (Cisco Certified Network Professional) - Cisco Certified Network senior engineer. Routing and switching authentication helps identify network engineers' ability to design, implement, validate, troubleshoot and collaborate with other network experts on advanced network security, voice, wireless and video solutions for local area networks and wide area networks. For those who have at least one year working experience in network, and are ready to improve the skills and independent working ability of complex network solutions, CCNP routing and switching authentication is very suitable.

Candidates who have obtained CCNP routing and switching certification prove that they have the necessary skills for enterprise positions such as network engineer, network support engineer, system engineer or network technician. The knowledge of routing and switching protocols in this authentication will provide you with a persistent knowledge base suitable for today's physical networks and future virtualized networks.

[Cisco certification system is divided into the following certification levels from low to high]
CCNA (Cisco network technology assistant engineer certification) → CCNP (Cisco network senior engineer certification) → CCIE (Cisco Internet expert certification).

Due to CCNAAs a basic level of certification, gold content will be relatively low, so many candidates will want to directly test CCNP. At present, however, Cisco stipulates that it must pass the CCNA exam before taking the CCNP exam (and the CCNA certificate cannot be expired). So candidates can not directly test CCNP, candidates need to first pass the CCNA and then CCNP test.

If you want to get the CCNP, you need to apply for the CCNA certification examination first, and then take the CCNP examination within three years after passing the CCNA. Why three years? Because the validity period of CCNA is three years. If more than three years, you need to carry out the re certification of CCNA, that is, take another CCNA certification, and then take the CCNP examination.

As for re certification, no matter which level of certificate is valid, CCNP certification is valid for three years. In case of re certification, you must pass any one of the three subjects in the CCNP grade examination within the validity period of the certificate, or pass the existing CCIE written examination.

As an international well-known network equipment manufacturer, Cisco certification enjoys a certain popularity in the world, among which CCNA and CCNP are the most popular network certification. There are mainly the following:
Cisco Certified Network Association (CCNA)
Cisco Certified Network Professional (CCNP)
Cisco Certified Design Association (CCDA)
Cisco certified design professional CCDP
Cisco Certified Internet expert (CCIE)

CCIE certification is the highest one in Cisco certification system, which is more difficult and requires higher qualification.

Go deep into Cisco certification objects
the overall architecture of Cisco after-sales engineer certification system is pyramid shaped. From the bottom of the tower to the top of the tower, it is divided into three layers: CCNA (Cisco Certified Network Support Engineer), CCNP (Cisco Certified Senior Network Support Engineer) and CCIE (Cisco Certified Internet expert), as shown in the figure:

Cisco after-sales engineer certification system has three layers: CCNA (Cisco Certified Network Support Engineer), CCNP (Cisco Certified Senior Network Support Engineer) and CCIE (Cisco Certified Internet expert)
The first floor at the bottom of the tower is CCNA, which is called Cisco Certified Network Support Engineer or Cisco Certified primary networkEngineers, as can be seen from the figure, are the lowest level of Cisco certification. Their learning contents pay more attention to the popularization of basic knowledge of network, and they do not have high requirements for students' basic knowledge of computer specialty. Therefore, their certification and training objects are mainly focused on the following points:

-College students who are about to graduate and want to work in network and communication engineering
-Network and communication professionals with low education background
-Junior technical personnel engaged in network and communication industry (such as network administrators -of small and medium-sized enterprises)

For the second layer, CCNP has gone deep into the high-level network, such as advanced routing, Multilayer exchange these are the key contents of CCNP learning and application. Therefore, there will be corresponding higher requirements for the quality of personnel participating in the certification. First of all, in terms of qualification, the acquisition of CCNP certificate must be based on the CCNA certificate. Before participating in the CCNP certification examination, you must have the CCNA certificate to register, Most of the content in CCNP learning is based on CCNA. That is to say, when learning CCNP, many basic conceptual things (such as VLAN, routing protocol, network structure, etc.) explained in CCNA will be directly applied, However, it will not be introduced.

The authentication objects of CCNP mainly focus on:
1. System integrators and network integrators
2. Large and medium-sized network administrators
3. ISP(Internet service provider)
4. Network designer of large and medium-sized enterprises

CCIE, as the highest level certification in Cisco certification, does not need CCNA, CCNP certificate as the basis, but the technical requirements are very high, because the technology and application of CCIE has penetrated into the core part of the world network, it will not be limited to a small network application. The target groups of certification are mainly focused on
1. Backbone network design and analysts
2. Large scale system and network integrators
3. Cisco gold and silver agents
4. Key technical personnel related to telecom department
