more work? Exams test your learning and are also the most critical. You need to adjust your status. Be confident in the exam and never give up on the last question. You will definitely encounter something you are not familiar with or even have never been familiar with during the exam. Don't be nervous. Because you do not want to get a full score, it is important to test every question you know. If you have made a mistake on the question you know beca

Theoretical learningproblem 1 : How does the switch work? By learning the computer MAC address of each interface, it realizes the data communication of each computer, and the routing table of the router is similar, the switch is realized by the Mac-port mapping table.problem 2 : Two layer switch, three layer switch, router difference? Two-layer switch: For switching, LAN, WAN switching onlyLayer Three switch: Also known as the routing switch, with the

After three years of work in the network field, I personally think that learning Cisco network is basically equivalent to mastering the network. It is determined that ccna, ccnp, and CCIE (routing and switching) are adopted starting from routing and switching ). First, let'

result is in vain. Is that true for friends? After so long time, I finally felt that. Learning really requires a goal and a positioning. I will make a small Report on the process and progress of learning Cisco. I hope to help you learn more. At school, even if you are learning a computer, you can just learn it. This

BGP is a path vector routing protocol, which is to exchange routing information between autonomous systems in order to discover the most efficient way to access data somewhere on the Internet. How do I choose the best path for routing?
