Preparation and Study Resources Flashcards

Which Kubernetes component logs should a candidate check first when troubleshooting a node that shows as NotReady?

Answer: kubelet logs on the affected node

The kubelet runs on every node and manages pod lifecycle; its logs are the first place to diagnose a NotReady node.

A CKA study plan recommends spending extra time on NetworkPolicy. Why is this topic particularly challenging?

Answer: The declarative syntax is complex and the behavior is non-obvious without a CNI that enforces it

NetworkPolicy syntax is nuanced (ingress/egress selectors, podSelector, namespaceSelector) and only works when a supporting CNI like Calico is installed.

Which command quickly shows all API resources available in a cluster, useful for referencing short names during the CKA exam?

Answer: kubectl api-resources

`kubectl api-resources` lists every resource type with its short name, API group, and whether it is namespaced.

When a study resource mentions 'static Pods', what distinguishes them from regular Pods in a CKA context?

Answer: Static Pods are defined by YAML files in a directory monitored directly by the kubelet, not the API server

Static Pods are placed in the kubelet's staticPodPath directory and managed by the kubelet directly, bypassing the scheduler and API server.

Which certification is considered the logical next step after earning the CKA for engineers who want to specialize in application deployment?

Answer: CKAD (Certified Kubernetes Application Developer)

The CKAD focuses on developing and deploying applications on Kubernetes, complementing the infrastructure focus of the CKA.

A practice test reveals a candidate struggles with PersistentVolume binding. Which study scenario best addresses this gap?

Answer: Manually creating a PV, PVC, and Pod that mounts the volume, then verifying the binding lifecycle end-to-end

Walking through the full PV→PVC→Pod lifecycle hands-on reveals how access modes, storage classes, and capacity affect binding.

Which exam time management strategy is most recommended for the CKA's 2-hour format?

Answer: Flag difficult questions, complete easier ones first, then return to flagged items

Skipping and flagging hard questions ensures you capture all easier points before spending extra time on complex tasks.
