A pod named 'batch-job' is running a data-processing script. The script writes a report to /tmp/report.csv inside the container. The pod is about to be deleted, and you need to retrieve this file to your local machine for analysis. Which command copies the file out of the container?

kubectl exec batch-job -- cat /tmp/report.csv > report.csv

kubectl attach batch-job > report.csv

kubectl logs batch-job > report.csv

kubectl cp batch-job:/tmp/report.csv ./report.csv

A developer needs to see the recent events and conditions for a service named `web-frontend`. Which command provides this detailed information?

kubectl events service web-frontend

kubectl describe service web-frontend

kubectl get service web-frontend

kubectl logs service web-frontend

A pod named 'app' runs an interactive CLI tool that requires user input. You need to interact with this tool to test a specific command sequence. The pod has a single container. Which command provides an interactive session with the container's main process?

kubectl exec -it app -- /bin/sh

kubectl port-forward pod/app 8080:8080

A pod named 'etl' has a container that writes a large output file to /data/output.csv. The pod is scheduled to be deleted in 5 minutes. You need to retrieve the file, but you also want to verify its integrity by checking its size before copying. Which approach is most efficient?

kubectl exec etl -- ls -l /data/output.csv && kubectl cp etl:/data/output.csv ./output.csv

kubectl cp etl:/data/output.csv ./output.csv && kubectl exec etl -- ls -l /data/output.csv

kubectl logs etl | grep output.csv

kubectl describe pod etl | grep output.csv
