CKA Preparation and Study Resources 5

Question 1

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

Accepted Answer

kubelet logs on the affected node

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

kubectl api-resources

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

CKAD (Certified Kubernetes Application Developer)

Answer

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