CCNA, CCNP, and CCIE are all certifications for network engineers from Cisco in the United States.

1. CCNA
CCNA is the primary certification. The CCNA certification marks the ability to install, configure, and operate a medium-sized routing and switching network, and to perform troubleshooting. Professionals who have obtained the CCNA certification have the corresponding knowledge and skills to establish connections with remote sites through the WAN, eliminate basic security threats, and understand the requirements for wireless network access. CCNA training includes (but is not limited to) the use of the following protocols: IP, EIGRP, serial line interface protocol, RIPv2, VLAN, Ethernet, and access control lists (ACL).

Second, CCNP
CCNP is an intermediate certification. CCNP professionals indicate that certified personnel have rich network knowledge. Professionals who have obtained CCNP certification can install, configure and run LAN, WAN and dial-up access services for large enterprise networks with more than 100 to 500 nodes. Starting from February 20, 2020, the CCNP exam subjects will start the new CCNP exam policy.

3. CCIE
CCIE is an expert certification. This certification is recognized as the most authoritative certification in the IT industry worldwide, and is the top certification in the global Internetworking field . In addition to the gold content, there are many differences between the CCNA, CCNP, and CCIE. The gold content determines the difficulty of taking them. CCNA has a written test and CCNP has three written tests. In addition to the written test, CCIE also A laboratory exam is required.

CCNA, CCNP, and CCIE are not compulsory advanced restrictions, so candidates can directly choose to apply for the CCIE, but the CCNP test must first obtain a CCNA certificate.

For the question of how to prepare for the exam, the difficulty of CCNA and CCNP will be slightly lower, and CCIE requires a certain amount of project experience accumulation, because the CCIE lab exam is difficult, the exam time is 8 hours in total, and the TS module time is the most 2.5H can be used, and it can be ended early. The DIAG module time is fixed at 0.5H, and the module cannot be ended early; CFG module: If TS uses 2.5H, CFG has 5H remaining.

For network engineers, it is necessary to obtain relevant certifications from Cisco. Cisco certified network engineers belong to a profession with strong technical expertise, and the shortage of qualified personnel is increasing rapidly with the popularity of the network. And the employment direction is almost unlimited, data center engineers, network security engineers, corporate network administrators, etc. With the accumulation of experience, you can become a project director, product manager, or engage in research and development. A pass allows you to stand out in employment and many other competitions. Cisco certification is a highly prestigious network skills certification in the Internet industry. Obtaining Cisco certification is undoubtedly a powerful stepping stone for entering the network industry.

Although no system is ever 100 percent protected, the ability for differentiating between typical network traffic as well as potentially harmful malware is considered crucial and provides the focus of this associate-level certification path. Also, if you wish to acquire this certification, you should gain the CCNP 300 501 SPCOR Dumps, which are being offered at the ITCertDumps.
