Of all the questions we receive, the most frequent is “What separates ExSim-Max practice exams from others on the market?” In a word, quality. Our content developers have been writing practice exams for over 20 years, and they bring that knowledge and experience to each product. An ExSim-Max product typically includes three separate exams. The content on each exam is carefully balanced to give you the appropriate coverage appropriate to the individual topic proportions. Every item consists of a question, answer, and a detailed explanation. Those explanations are invaluable. Each explains not only why the correct answer is correct, but why the incorrect answers are wrong. And each question is backed up with relevant sources and our Curriculum where available.

** Aug 24, 2017 11:20:34 AM / by [Andrew Messier](https://blog.boson.com/author/andrew-messier) posted in [ICMP Port Numbers](https://blog.boson.com/topic/icmp-port-numbers)

[** 2 Comments](https://blog.boson.com/icmp-port-numbers#comments-listing)

Various application layer protocols listen on specific ports. For example, when you want to visit a website, the HTTP request that exits your computer is destined for TCP port 80 on the remote server. The source port on your computer is an arbitrary ephemeral port. The request is processed on the server, and data returns to your computer destined to the previous source port where your web browser (probably Chrome) is ready and waiting.

With CiscoLive 2017 quickly approaching, I'm looking ahead and reviewing my notes from last year. One question we frequently receive throughout the conference is, "What makes NetSim different than ____?" or, "I have real equipment, so why would I use NetSim?" We enjoy answering this question because people normally walk away with a better understanding of our product and plan to use it for themselves or for their students. My goal is not to knock the other options, because there are a lot of great resources out there. Instead I aim to be as informative as possible to help you make a smart buying choice.
