A pod is being evicted from a node due to memory pressure. The team wants to prevent this from happening again. They have already set memory requests and limits on the pod. What else should they consider?

Increase the memory limit on the pod to give it more memory.

Set a memory request higher than the limit.

Remove the memory limit to allow the pod to use more memory.

Check if the node has enough allocatable memory and consider adding more nodes or reducing the number of pods on the node.

A team deploys a batch processing pod that occasionally spikes in CPU usage. They set a CPU request of 500m and a limit of 1 CPU. During a spike, the pod exceeds its limit. What is the immediate consequence?

The pod is terminated and restarted by the kubelet.

The pod is evicted from the node.

The pod is marked as failed and a new pod is created.

The container's CPU usage is throttled to the limit.

What happens when a container exceeds its memory limit in Kubernetes?

The pod is evicted from the node

The container is terminated by the kernel

The container is restarted automatically

The container is throttled and runs slower

Part of the Container Orchestration domain, which accounts for 28% of the KCNA exam. Linux Foundation does not publish an official question count, but from its 90-minute exam (~35–60 total, ~10–17 in this domain), expect 5–9 from this objective — we provide 25 practice questions to prepare you well beyond it.
