A pod has been in Pending state for several minutes. The cluster has three nodes, each with 2 CPU and 4 GiB memory. The pod requests 3 CPU and 2 GiB memory. No taints or affinity rules are configured. What is the most likely reason the pod is not scheduling?

The nodes are tainted with a taint that the pod does not tolerate.

The pod's CPU request exceeds the available CPU on any node.

The pod's memory request exceeds the available memory on any node.

In the Kubernetes scheduling process, what is the purpose of the filtering phase?

To rank the remaining nodes and pick the one with the highest score

To add labels to nodes that match the pod's requirements

To bind the pod to the first node that passes all checks

To eliminate nodes that cannot run the pod due to constraints like resources or taints

A cluster has nodes with labels `disktype=ssd` and `disktype=hdd`. A workload requires fast storage, so it should be scheduled on SSD nodes. However, if no SSD node is available, it is acceptable to run on HDD nodes. Which node affinity rule should be used?

`preferredDuringSchedulingIgnoredDuringExecution` for `disktype=ssd`

A toleration for a taint on HDD nodes

`nodeSelector: {disktype: ssd}`

`requiredDuringSchedulingIgnoredDuringExecution` for `disktype=ssd`

What is a common use case for manually scheduling a pod with nodeName?

To place a pod on a specific node for testing or troubleshooting

To ensure the pod runs on a node with a specific GPU

To run a system daemon on every node

To spread pods evenly across nodes

Part of the Kubernetes Fundamentals domain, which accounts for 44% of the KCNA exam. Linux Foundation does not publish an official question count, but from its 90-minute exam (~35–60 total, ~15–26 in this domain), expect 3–4 from this objective — we provide 31 practice questions to prepare you well beyond it.
