CCNA CONCEPT AND HARDWARES

In this post, I am going to cover the CCNA concept and objectives that is designed by CISCO for CCNA exam with supportive information. This post will take you through CCNA terms and definition, the benefits and the hardware you will encounter in the course of CCNA training programme.

In CISCO wall, there are three level of certifications

1.      The first one is the associate level. The associate level has two categories.

CCNA – Cisco certified network associate

CCDA – Cisco certified design associate.

Here there is only one exam that is involve and it last for the duration of 75mins with 45 to 55 questions given.

2.      The second level is the professional level which also has two categories

CCNP - Cisco Certified Network Professional

CCDP -   Cisco Certified Design Professional

3.      The highest level is the expert level

CCIE – Cisco Certified internetwork Expert

 Benefits of CCNA Certification

Peer validation This helps you to get good understanding as to where you are in the industry among other people that do the same kind of job. There are two reasons for doing that

First is for personal reason this helps you like I said earlier to get a better understand as to where u are and set your path in the right direction for the right carrier  and second reason is for Potential employer, in this, you differentiate yourself from the pack for a potential employer. Certification helps differentiate you from the pack because employers tends to look at distinct skill in a employees that singles them out from the crowd and certification is a sure bet.

Career Advancement. This can happen within or outside the company. Getting certified pushes you through and up in the hierarchy of a company, you will always be considered first.

The last on the list is directional study. This directs you to lay the foundation of a building before putting up a structure and then finally the roof. What I am implying here is that CCNA is the foundation in cisco networking and CCNP the structure while CCIE is the roof. When acquired in this directional order You will totally be grounded.

HARDWARE

There are three layers here in cisco hardware. The 3^rd layer / network layer is the highest level and uses routers. The routers are divided into two groups, the higher routers and Access product. In the 2^nd layer or datalink layer is switches and bridges. The switches make use of WAN (Wide Area Network) and LAN (Local Area Network). While the 1^st layer or the physical layer and also the lowest level uses cable as shown in the pictures below.
