In last week’s TR Dojo episode, I showed you five netstat tricks that can help admins manage their networks and troubleshoot problems. Where you paying attention? Are you already a netstat ninja? Take this short quiz and test your knowledge.
Note: Unfortunately, our poll tool, which I use to create each pop quiz, doesn’t let me indicate a correct answer after each question. To keep from giving away the answers before everyone has a chance to test his/her knowledge, and ruining all the fun, I’ve published the answers on the second page of this blog post. I encourage everyone to answer all the questions before looking at the second page or using your favorite search engine to find the answers.
