دانلود کتاب 101 آزمایشگاه Wireshark WCNA

There are so many IT career paths to choose from, network administration, security, wireless engineer, DevOps, service provider, data center, helpdesk, design, to name just a few. One common thread which joins them all is the requirement to understand how IP traffic crosses your network. Capturing traffic is often referred to as sniffing. It’s a vital skill for any network engineer because it allows you to:

• Baseline your network
• Troubleshoot faults
• Quickly find the root cause of issues
• Detect network attacks
• Find protocol issues with DHCP, DNS, HTTP, Email, and more
• Troubleshoot voice, video, and wireless issues

Being able to capture traffic will help you quickly find the root cause of issues so you can either resolve them yourself or present your findings to customers or managers. You will often be asked to sniff network traffic as part of your day-to-day job. Wireshark is the premier network sniffing tool available on the market. Passing the Wireshark Certified Network Analyst exam will make you stand out from your colleagues because it proves you have advanced troubleshooting skills and a deep understanding of TCP/IP. 101 Labs—Wireshark WCNA will give you a solid foundation and help you prepare for and pass the exam. Please use these labs as a starting point. We add suggestions to the end of most of the labs, so please make your own labs up and explore every menu item, graph, and packet type you can. We presume you already have a good understanding of TCP/IP. If you need to improve your knowledge, then please read a good quality CompTIA Network+ book, check out our video course for the Network+ on howtonetwork.com and also please read our 101 Labs—CompTIA Network+ book which will be a great complement to this one. We also teach Wireshark from scratch on www.howtonetwork.com .
