The most famous certificate in the communication industry should be the Cisco CISCO certification.
One of the most important factors in whether a certification can attract a large number of
followers for a long time is the market position of the parent company where the certification is
located. As a veteran network equipment manufacturer, Cisco has long had a large market share
and status in the industry.

Everyone should be familiar with these words: CCNA, CCNP, CCIE. They represent the three main
levels of Cisco certification.

Among them, the "A" of CCNA means Associate, "joint, partner". CCNA is the most basic and widely
used part of Cisco's professional certification system, which is quite the basic requirement for
entering the industry.

The "P" of [https://www.spotoclub.com/Mastering-CCNP-Enterprise-Certification-A-Complete-Guide-9952/]CCNP is Professional[https://www.spotoclub.com/Mastering-CCNP-Enterprise-Certification-A-Complete-Guide-9952/, which means "professional ". Obtaining the CCNP certification
means that you have rich knowledge and skills, have certain experience accumulation, and belong
to a senior network engineer.

CCIE, is the best, "E" is Expert, "expert" means. For a long time, CCIE has been recognized as the
most authoritative and respected certification in the IT industry, and it is the top certification in
the global Internetworking field. Among the millions of Internet practitioners in the world, CCIE
accounts for less than 1%. CCIE has also occupied the top of the IT certification list for a long time
and is known as the IT ultimate certification. Skilled immigration is a plus. Not to mention the
salary, CCIE can reach the highest annual salary of one million yuan many years ago.

In fact, the architecture of Cisco certification is not limited to these three layers. To be precise,
Cisco certification consists of 5 levels.

Under the CCNA, there is actually a CCENT, the Cisco Certified Entry Networking Technician, which
is very simple and can almost be ignored.

On top of CCIE, there is another CCAr, Cisco Certified Architect. There is no best, only more cattle.
Cisco really took great pains.

On the CCAr line, the levels corresponding to CCNA, CCNP, and CCIE are also called separately:
CCDA, CCDP, and CCDE. D means Design. To put it bluntly, this newly opened technology tree is
designed with partial architecture. Each different grade is also divided according to different
product business directions. Such as CCNP, including routing and switching, security, voice and so
on.

The reference learning cycle corresponding to each level is as follows CCNA: It is recommended that the self-study time be 1 month, and the training institution can basically finish the lecture in 6 days.

CCNP: It is recommended that the self-study time be 2 months, and the training institution will
basically solve it within 20 days.

CCIE: It is recommended to study for half a year.

All in all, Xiao Zaojun believes that Cisco, as an old-fashioned communication equipment
manufacturer in an old capitalist country, although for some reasons, its market share in China has
declined, and the gold content of certificates has also declined, but it is still a powerful
communication company. , its certification is still higher value.
