Failed CCNA because of Subnetting?

Occasionally we get an email at Internetwork Training HQ that reads something like this...

"I just failed my ccna exam today. I'm weak at subnetting and these questions cost me the exam! Can you help??"


Our advice is, don't walk into the CCNA exam without being prepared! Subnetting is a vital skill to the network engineer and you WILL be tested on it, so make sure you understand how to subnet before you take your CCNA exam.

You need to be able to solve subnetting problems quickly under test conditions, that means no calculators or subnetting tools!

If you are struggling with subnetting, we have a great subnetting eBook that you can purchase. It comes included with our popular CCNA cheat sheet, and has plenty of examples to help you learn.

CCENT Video Training Boot Camp

We offer an online CCNA video course that contains all the training and exam preparation materials you need to study for the CCNA exam, however some students prefer to take the two exam pathway to gain their CCNA certification. This involves studying and passing the ICND1 and ICND2 exams. When you pass the ICND1 exam you become CCENT certified, this allows you to study for the ICND2 exam which will make you CCNA certified.

While our CCNA Bootcamp is designed to train you up to the CCNA level you can also use it to train for the ICND1 (CCENT) and ICND2 exams, enroll in the course and watch the appropriate videos of our course below.

Why a Career in Networking?

Here at Internetwork Training HQ, We often get asked why students should pursue a career in networking?

If you are a technology-minded individual who enjoys using computers and the internet, you will probably find networking a rewarding career choice.

Networking is a vital tool in information technology, without it we would not be able to connect devices together to share and communicate, we also would not have the internet! This would be like computing was in the 1970's and 1980's!

There are many jobs you can do with a networking certification such as the Cisco CCNA, many of which may also lead to management or other senior roles in IT should you be interested later in your career.

Once you get into networking and have a few years experience you can then specialize in an area of networking, such as VoIP, security or wireless, this will give you more sought after skills that will earn you higher incomes in the marketplace.

To see the variety of jobs you can do with a CCNA certification, plus the kinds of salaries for jobs in your local area please check out our CCNA job board.
