This course will focus on building the skills that you need to get started with the Command Line Interface (CLI). It will cover basic navigation, program installation, reading logs, and troubleshooting issues. We will also dive into network troubleshooting and common AWS scenarios that you may encounter as a Cloud Support Associate. In the first section of this course, we will focus on how to navigate in a Linux environment using only the CLI. We will explain how to create files, directories, and the commands you need to manage your system. We will also discover how to set permissions in the environment as well as edit text and configuration files. In the second section, we’ll go a bit deeper into the CLI and learn about troubleshooting tools that we have available to us. You’ll see how to test networking connectivity as well as install and configure Linux applications. The third portion of this course will focus on network troubleshooting in AWS. We’ll discover the common ports that can cause problems when setting up security groups and network access control lists (NACLs). We’ll also learn how AWS handles DNS and the steps you can take if something isn’t resolving correctly. Finally, the course concludes by covering common troubleshooting scenarios. What do you do when your Linux application keeps crashing? How about a troublesome SSH connection that isn’t working? Where do you look if your hosts are missing internet connectivity? By the end of this course, you’ll have a strong technical foundation in the skills needed to troubleshoot IT problems as a Cloud Support Associate.
