Answer options:
A.
gcloud compute instances tail-serial-port-output [NODE_NAME]
B.
kubectl describe pod [POD_NAME]
C.
kubectl logs [POD_NAME]
D.
gcloud container logs read [POD_NAME]
How to approach this question
Identify the Kubernetes command used for viewing application logs.
Full Answer
C.kubectl logs [POD_NAME]✓ Correct
The `kubectl logs` command is used to print the logs (stdout and stderr) from a container in a pod. This is the primary way to troubleshoot application crashes or errors within Kubernetes.
Common mistakes
Using `kubectl describe`. While useful for troubleshooting why a pod won't start (e.g., ImagePullBackOff), it does not show the application's internal logs.
