Troubleshoot systems and networks with a structured, repeatable methodology instead of trial and error. This module prepares IT support staff, help desk technicians, and aspiring systems administrators and cloud operations engineers to diagnose network connectivity failures, DNS and name resolution problems, and latency or slow network performance. Learners practice fault isolation and root cause analysis through five steps: define, isolate, test, resolve, and document. They learn to run diagnostic tests, interpret what each test shows, locate the point where a request fails, confirm a fix, and write a clear troubleshooting runbook entry for the next person. Built for IT operations, network administration, system administration, and site reliability roles, this module develops the diagnostic skills that shorten outages and reduce downtime.

Automate Linux Tasks with Bash Scripting teaches IT professionals, system administrators, cloud operations staff, and aspiring DevOps engineers how to turn repetitive command-line work into reliable shell scripts. Learners practice Linux task automation, Bash scripting fundamentals, and error handling, including exit codes, scripts that stop at a failed step, and scripts that are safe to run again. They also learn to make unattended automation auditable by writing a dated run log that records how each run ended. Through realistic operations scenarios, stakeholder perspectives, hands-on practice, and an expert demonstration, learners build in-demand IT automation skills for systems administration, IT operations, cloud operations, log management, and backup tasks.

Automate repetitive IT work across operating systems, and keep it dependable when nobody is watching. This module covers systems administration, IT automation, and workflow automation: turning a manual chore into a script, scheduling it to run unattended at a set frequency, and confirming afterward that the work was done. You practice job scheduling, scheduled tasks, cross-platform scripting, task automation, logging, and monitoring. You also learn how triggers, run-as accounts, and script safety settings shape what an unattended job can do. The module builds a core IT operations habit: verifying automated work from the records it leaves behind, the kind of evidence that supports system reliability, troubleshooting, and audits. It suits career starters and career changers moving toward systems administrator, IT operations, and cloud operations roles.
