You created two GKE clusters, prod-cluster (standard) and dev-cluster (autopilot). kubectl get nodes only shows nodes from prod-cluster. Which commands will load dev-cluster credentials and show its nodes?

The correct command is gcloud container clusters get-credentials dev-cluster. This command fetches the credentials for dev-cluster and configures kubectl to use them, making dev-cluster the current context. After this, kubectl get nodes will correctly display the nodes for dev-cluster. The other options are incorrect: gcloud container clusters update -generate-password dev-cluster is used to update cluster settings, not to get credentials or switch contexts. kubectl config set-context dev-cluster would attempt to set a context named dev-cluster but wouldn't fetch the necessary credentials, and kubectl cluster-info only shows information about the current cluster, not its nodes. kubectl config set-credentials dev-cluster is used to define user credentials, not to retrieve cluster credentials or switch the active context.
