"I can't imagine what this job would be like if I were unable to access online resources when I encounter an issue that is new or with which I am not familiar. I've made it a point to identify key resources I can use for this purpose, learn how to use them, and bookmark them so they are easy to reach. Some of the key ones I work with for this purpose include GitHub, Coursera, and Reddit. I also use the vendors' websites and subscribe to several different user forums in which other systems engineers post solutions to issues they've encountered."
