How to find which process is using a specific port? How to troubleshoot high CPU usage on Linux? How to find your machine’s IP address from terminal? Explain crontab and write a cron job to run every 5 minutes. How to search for a string in multiple files? App deployed but not accessible – how to check if service is running and listening? How to kill all processes running for a particular application? Explain a Kubernetes deployment file. AWS questions on Security Groups, IAM, EC2, S3, EKS. Tell me about yourself. What is DevOps?
