You are troubleshooting a performance issue in a namespace called 'prod'. Users report that a specific application is slow. You need to gather initial diagnostic information. Select all commands that would be useful for this initial triage.

kubectl events -n prod --types=Warning

A pod named 'app' has a single container that writes structured logs to stdout. You need to see only the lines containing 'ERROR' from the last hour to quickly triage issues. Which command achieves this?

kubectl exec app -- grep ERROR /var/log/app.log

kubectl logs app -f | grep ERROR

kubectl logs app --since=1h | grep ERROR

kubectl logs app --tail=100 | grep ERROR

Your cluster has 5 nodes. You need to identify if any node is approaching its memory limit to plan for scaling. Which command shows the memory usage of all nodes in a summary table?

kubectl top pods --sort-by=memory
