How to become CCNA certified?

You can become CCNA certified in two ways:

1. by passing  the CCNA 200-125 CCNA exam ($325).
2. by passing the ICND1 100-105 exam and ICND2 200-105 (165 $ each).

The CCNA 200-125 exam covers the topics from both ICND exams.

If you pass the ICND1 exam, you will receive a certification called CCENT (Cisco Certified Entry Networking Technician).


The CCNA 200-125 exam consists of 60-70 questions. The ICND exams have 45-55 questions. The highest score you can achieve on either exam is 1000. The minimum passing score is somewhere around 830.

Where to take the exam?

To take the CCNA exam you have to schedule a test appointment through Pearson VUE, an electronic testing company. Pearson VUE has many authorized testing centers throughout the world and you can locate a test center in your vicinity.

The exams are available in English and Japanese and lasts for 90 minutes, unless you aren’t a native speaker of any of these two languages. If that is the case, you will get a 30 minutes time extension. After finishing the test you will immediately get the results. Cisco provides just the basic information about your score, so you can’t be sure which questions you got right or wrong!

Preparing for the exam

There are several ways in which you can prepare yourself for the exam:

  • attending a CCENT or CCNA course – Cisco courses are offered by various educational companies and institutions. You can use this online tool to locate an academy in your vicinity. These courses usually lasts a couple of months and include a lot of hands-on activities. Prices vary depending on your location, but the courses can be quite costly (up to $1000).
  • self-study with textbooks and online courses – another popular way to prepare a CCENT exam is by self-studying. There are lots of high-quality resources online and tools such as GNS3 or Packet Tracer that enable you to study without actually buying expensive equipment. Of couse, this website is one of these high-quality online resources :-). Many people use website like Ebay or Amazon to find CCNA kits that will enable them to work on real equipment.
  • concentrated boot camps – intensive, week-long live classes that cover months of materials in just five days. Not recommened for beginners.


You don’t need to attend a course academy in order to take the CCENT or CCNA exam.
