CKA YAML Configuration 3

Question 1

In a Kubernetes StatefulSet YAML, which field under `volumeClaimTemplates` defines the storage size requested per pod?

Accepted Answer

resources.requests.storage

Answer

The `resources.requests.storage` field inside `volumeClaimTemplates[].spec` specifies how much storage each StatefulSet pod requests.

Question 2

Which YAML structure correctly defines a Kubernetes Service that exposes port 80 externally and targets port 8080 on pods?

Accepted Answer

ports: [{port: 80, targetPort: 8080}]

Answer

A Service spec uses `port` for the Service's exposed port and `targetPort` for the container port it forwards traffic to.

Question 3

What does the `imagePullPolicy: Never` field in a container spec instruct Kubernetes to do?

Accepted Answer

Never pull the image; use only locally cached images

Answer

`imagePullPolicy: Never` tells the kubelet to never pull from a registry, failing if the image is not already present locally on the node.

Question 4

In a Kubernetes YAML, which field in a container spec maps a host path to a container path?

Accepted Answer

volumeMounts[].mountPath paired with a volumes[] hostPath entry

Answer

A `hostPath` volume is declared in `spec.volumes[]` and mounted into a container via `spec.containers[].volumeMounts[]` with a `mountPath`.

Question 5

What is the purpose of the `terminationMessagePath` field in a Kubernetes container spec?

Accepted Answer

Path where the container writes its termination reason message

Answer

Kubernetes reads `terminationMessagePath` (default `/dev/termination-log`) to surface the container's exit reason in Pod status.
