A pod remains in Pending state. What is a common reason for this?

The pod has a nodeSelector that matches no nodes

The pod's container image is too large

The pod has too many containers

The pod's restart policy is set to Never

What happens if a container exceeds its memory limit?

The pod is rescheduled to another node

The container may be terminated by the kernel (OOM kill)

The limit is automatically increased

A pod is stuck in Pending. The cluster has two nodes: Node A has 1 CPU and 2 GiB memory, Node B has 2 CPU and 4 GiB memory. The pod requests 1 CPU and 3 GiB memory. The pod also has a nodeSelector for `disktype=ssd`, and only Node A has that label. What is the most likely reason the pod is Pending?

The scheduler is not configured to use nodeSelector.

The pod's CPU request exceeds the CPU available on Node A.

The pod has a taint that Node A cannot tolerate.

The pod's memory request exceeds the memory available on Node A, which is the only node matching the nodeSelector.
