AWS and Linux Troubleshooting Questions

Demonstrate the ability to diagnose and remediate operational issues across cloud resources and Linux hosts. Expect scenarios such as virtual machine connectivity problems, security group or network access control misconfiguration, identity and access management permission errors, managed database access issues, and operating system problems like file permission errors, hung processes, disk exhaustion, and network connectivity faults. Candidates should describe evidence collection from system logs, common command line diagnostics, safe remediation steps, and how to escalate or rollback changes when necessary.
