This Second Edition includes an introduction to IPv6, ICMPv6 and DHCPv6 analysis, updated Wireshark functionality and new trace files. This book is the Official Study Guide for the WCNA Certification (formerly known as the Wireshark Certified Network Analyst certification). Build graphs to identify and expose issues such as packet loss, receiver congestion, slow server response, network queuing and more. ![]() Learn to customize Wireshark for faster and more accurate analysis of your network traffic. This book provides insider tips and tricks to spot performance issues fast - no more finger pointing because the packets never lie! From "Death by Database" to "Troubleshooting Time Syncing," 49 case studies offer insight into performance and security situations solved with Wireshark. I practiced a few sample tests from Udemy and Chappel university which in turn boosted my confidence to clear the exam with more than 90% score! :)Įxams are available online as well as classroom-based ones.Wireshark is the world's most popular network analyzer tool with over 1 million downloads per month. Once you are ready with the preparation, online self-evaluation tests are available before taking the actual exam. But preparation helps you to refresh your high-level basics and understand more about packet communication. The exam was easy since it covered all the exam topics from the official book and prep guide. What is the level of difficulty in the exam ? Wireshark Certified Network Analyst Exam Prep Guide (Second Edition). Wireshark Network Analysis (Second Edition): The Official Wireshark Certified Network Analyst Study Guide.

There was a topic called, “TCP congestion control and Avoidance” which turned all our focus into packet communication on network. That was the time we went “BACK TO BASICS” on OSI and TCP/IP. Students were very attentive and interactive which encouraged me to provide a session with real-time examples and packet analysis. During those sessions, I interacted with the students about the basics of core networking and the latest trends in the networking world. My sincere thanks to the professors KALAISELVI T PARAMASIVAM and MAHESH for those sessions. Wireshark acts as a Language translator, which captures the encapsulated packets from the network and represents it on the OUI (Organic User Interface) with reference to the TCP/IP model.Ī few weeks back, I got an opportunity to interact with engineering students on their networking subject through guest lecture sessions. If we understand the language of packets, then the fix is almost done. Most of the time at work, we try to understand how packets are communicating, what they like, and don’t like on the network path. Network issues have to be assessed and resolved as quickly as possible for better customer experience. My core work is to break fixing the customer’s global network when there is an outage. How I got a sudden interest to pursue WCNA? If you feel that the exam is right for you, please continue.
