A pod is in a `CrashLoopBackOff` state. The engineer wants to see the logs from the previous container instance to understand why it crashed. Which command should they use?

kubectl exec -it pod/my-pod -- /bin/sh

kubectl logs pod/my-pod --previous

An application needs to read a configuration file that contains both sensitive and non-sensitive settings. The team wants to mount this as a volume in the pod. What is the best practice for managing this configuration?

Create a single ConfigMap containing all settings and mount it as a volume

Create a ConfigMap for non-sensitive settings and a Secret for sensitive settings, then mount both as separate volumes
