Cisco 300-420: What? And How?

Exam 300-420 is suitable for system administrators, network engineers, and networking design engineers. All in all, there are several knowledge areas that you need to have a deep understanding of in order to pass such a test successfully. Thus, you should be familiar with the following:

  • Building simple LANs and basic network fundamentals.
  • Routing & switching basics;
  • Basic IP addressing and subnets;
  • Fundamental wireless networking notions as well as terms;

The most important information to look for after knowing that you qualify for such an exam is the skills measured. Generally, it is usually stated clearly through the topics covered. For this test, the main objectives are network services, advanced enterprise networks, automation, advanced addressing and routing solutions, network services, as well as WAN for enterprise networks. The exam format is another detail that you need to know about. Overall, there will be 60 multiple-choice questions, which you should complete within 90 minutes. You will certainly be able to answer all of them and get more than 825 points if you prepare wisely. Therefore, consider going for the official training and other prep resources, such as study guides, videos, and sample questions. To sit for this test, you need to pay $300 for the voucher. Also, please note that you can take it in English or Japanese. After you pass 300-420, you will get one of the Specialist certificates and the CCNP Enterprise if you take the Cisco 350-401 as well.

There are a number of ways to follow this process. You can do so by taking the necessary exams or completing education activities. What is more, you can also do a combination of both.
