Answer options:
A.
Enable cluster autoscaling on the node pool.
B.
Enable Horizontal Pod Autoscaling (HPA).
C.
Manually resize the node pool to add more nodes.
D.
Restart the pending pods.
E.
Change the Service type to LoadBalancer.
How to approach this question
Identify the mechanisms for adding compute capacity (nodes) to a GKE cluster.
Full Answer
Enable cluster autoscaling on the node pool.
Manually resize the node pool to add more nodes.
Pods remain in the `Pending` state when the Kubernetes scheduler cannot find a node with enough available CPU or memory to run them. To fix this, you must add more compute capacity. You can do this manually by resizing the node pool (`gcloud container clusters resize`), or automatically by enabling the Cluster Autoscaler, which watches for pending pods and provisions new nodes.
Common mistakes
Selecting Horizontal Pod Autoscaler (HPA), which scales pods, not nodes.
