There are five types of CCIE certificates: 1. Route switching (RS) route switching CCIE.

2. Service Provider (SP) Telecom Operator CCIE

3. Safety CCIE

4.CCIE voice

5.StorageNetworking stores CCIEIPv6 routing exchange CCIE authentication content.

Introduction to certification:

CCIE certification qualification in the field of routing and switching means that network personnel have expert knowledge in different LAN and WAN interfaces and networking of various routers and switches.

Experts in the field of RS can solve complex connection problems and use technical solutions to improve bandwidth, shorten response time, maximize performance, strengthen security and support global applications.

Candidates should be able to install, configure and maintain LAN, WAN and dial-up access services.

Ccie exam fee?

First of all, the cost:

1, CCIE Qualification Examination (i.e. written examination, 2.5 hours) Examination fee: USD 450;

2.CCIE experimental examination fee (laboratory, 8-hour configuration): 1.600 USD, Beijing test center 1.900 USD, and mobile test center1.900 USD.

Second, the specific process:

1, the last course from NA to IE in the training class or self-taught course system, with the deepening of learning, the understanding of the network will gradually deepen, and the network concept and model established in the mind will not take detours under the guidance of teachers. If you have strong understanding, self-learning ability and equipment, you can learn by yourself.

Read several reference books carefully. Formal learning can form a whole concept system in your mind, which is equivalent to setting up a skeleton, but the detailed content still depends on your own reading.

3. Taking the CCIE CCIE written test is divided into two steps. You must pass the written test before you are qualified to take part in the experiment. The written test can be conducted at the test sites of Prometric or VUE test centers in major cities of China. You can call for advice.

4, do a lot of experiments CCIE exam is called the most demanding exam, because it requires candidates to have strong practical ability. Therefore, a lot of experiments are needed.

5. Take the CCIELab exam within 18 months after passing the written test. Overdue, the written test results are invalid. After passing the written test, Cisco will send a confirmation letter within ten days so that you can make an appointment for CCIELab test.

CCIECCXPCCNA which is widely used?

Cisco certified was introduced by Cisco, a well-known network manufacturer. Cisco certified is an international authoritative certification in the field of Internet.

Let's talk about CCNA first CCNA certification (CCNA- Cisco Network Installation and Support Certification Assistant) is the most elementary certification in the whole cisco certified system, and it is also a necessary condition for obtaining CCNP certification, CCDP certification and CCSP certification (CCIP certification and CCIE certification are not mandatory, in other words, you can directly take CCIE or CCIP without taking CCNA), so it is the most basic certificate of CCNA. Because (CCNA certification belongs to the entry certification of Cisco after-sales engineer certification system)

For CCDA, CCDA certification (cisco certified Design Engineer) means having basic or preliminary knowledge of designing Cisco network infrastructure. You can understand it as the same as CCNA (but personally think CCNA is better). For CCDP, CCDP certification means mastering or being familiar with network design knowledge. Network professionals who have obtained CCDP certification can design routing and switching networks including local area network, wide area network and dial-up access services, and adopt modular design method to ensure that the whole solution meets business and technical requirements and has high availability. (CCNA must be passed before taking CCNP) For CCNP, CCNP certification (cisco certified network professional) means that Certification staff has rich network knowledge. Professionals with CCNP certification can install, configure and operate LAN, WAN and dial-up access services for large enterprise networks with more than 100 to 500 nodes. (To get CCNP, you must go through CCNA first) For CCIE；; CCIE Cisco Certified Network Expert Program (CCIEProgram) has set professional standards for network technology and has been widely recognized by the industry. CCIE certification is considered as the best proof of professional network technical knowledge and rich work experience. You can pass the exam directly, which is the most difficult.
