26. An application image runs in multiple environments, with each environment using different certificates and ports.

Is this a way to provision configuration to containers at runtime? Solution: Provision a Docker config object for each environment.

27. During development of an application meant to be orchestrated by Kubernetes, you want to mount the /data directory on your laptop into a container.

Will this strategy successfully accomplish this? Solution: Add a volume to the pod that sets hostPath.path: /data, and then mount this volume into the pod's containers as desired.

28. During development of an application meant to be orchestrated by Kubernetes, you want to mount the /data directory on your laptop into a container. Will this strategy successfully accomplish this? Solution: Create a PersistentVolume with storageciass: "" and hostPath: /data, and a persistentVolumeClaim requesting this PV.
