Since a CCNA 640-802 exam mainly covers routing technologies, it’s important to know the specific routing protocols and fundamental routing concepts particularly RIPv2. Understand how routing protocols such as EIGRP and OSPF fit into the network design and Cisco network architecture in general.

2. How well do you understand the OSI model?

You should have clear understanding of the seven layers of the OSI model and their relationship to one another. You should also know the flow the data throughout the network and model as well as identify where the network software and equipment operate in the layers and how they fit in the model.
