An administrator is preparing to upgrade a cluster from v1.20 to v1.21. Before the upgrade, the administrator wants to identify all resources that are using deprecated API versions. Which kubectl command should be used to list the API versions currently in use by resources in the cluster?

`kubectl get all --all-namespaces -o json | jq '.items[].apiVersion' | sort -u`

`kubectl get --raw /apis | jq '.groups[].versions[].version'`

`kubectl api-resources --verbs=list --namespaced -o name`

A developer is updating a Deployment manifest and notices the apiVersion field is set to apps/v1beta1. Which statement about this API version is correct?

apps/v1beta1 is deprecated and was removed from Kubernetes; the current stable version is apps/v1.

apps/v1beta1 is a valid beta API version that is still actively served and will never be removed.

apps/v1beta1 is a valid alpha API version that can be used in production clusters.

apps/v1beta1 is the current stable version for Deployments and will remain supported indefinitely.

An operator is troubleshooting why a `kubectl get ingresses` command returns an error about an unknown API version. The operator suspects the cluster is running an older version. Which command should the operator run to see which API versions are actually served for Ingress?
