CCNA Certification Training

Subnetting is one of the most important network lessons. It is especially important for entry level network engineers. Network engineers learn this lesson and how to calculate subnet mask at the beginning of many different certification paths. For Cisco CCNA Certification, Huawei HCIA , Nokia NRS I and Juniper JNICIA, it is very important and key lesson. So, network engineers need to know some special parts of subnetting. To overcome this, network admins use subnetting cheat sheet . Subnetting cheat sheet includes almost all necessary information for this calculation.   To practice on this lesson, there are different questions. In such questions, basically an IP address is given with a subnet mask and the usable ip addresses are calculated. Sometimes the required ip addresses can be host ip addresses and sometimes it is broadcast ip address or network addresses. Whatever it is, if you learn how to solve a subnetting question, then you will successfully achieve it. During this...

 There are different lessons in Cisco CCNA Certification. Network engineers need to learn these lessons and pass CCNA 200-301 exam. To do this, after learning each CCNA lesson, they should practice with different questions and answers with a CCNA practice test.  In this article, we will talk about key four lessons of Cisco CCNA certification. These lessons are the foundation lessons of Cisco CCNA certification.  OSI Model OSI Reference model is one of the most important beginner lessons of an entry level network certification. This model summarizes the network concepts and protocols. We can understand the level of networking with OSI model. There are seven layers in OSI model. These are: • Application Layer • Presentation Layer • Session Layer • Transport Layer • Network Layer • Data-Link Layer • Physical Layer You learn the protocols of each layer and the concepts of this layers. For example, in physical layer, you learn network cabling. Basically, osi mode...
