CKA Preparation and Study Resources 4

Question 1

Which kubeadm command is used to initialize a new Kubernetes control plane node?

Accepted Answer

kubeadm init

Answer

`kubeadm init` bootstraps a new control plane and is a core task covered in the CKA cluster installation domain.

Question 2

When studying RBAC for the CKA, which resource pair must you understand together to grant namespace-scoped permissions?

Accepted Answer

Role and RoleBinding

Answer

Role defines namespace-scoped permissions and RoleBinding attaches that Role to a subject within the same namespace.

Question 3

A study guide recommends practicing 'jsonpath output' with kubectl. Why is this skill important for the CKA?

Accepted Answer

It allows extracting specific fields from resource output for use in scripts or answers

Answer

JSONPath queries let you extract precise fields (e.g., node IP, image name) quickly, which is often needed to answer exam tasks.

Question 4

Which simulator is often recommended as a paid resource that closely mimics the real CKA exam environment?

Accepted Answer

killer.sh CKA simulator

Answer

killer.sh provides a browser-based terminal environment nearly identical to the real PSI exam interface and is bundled free with exam registration.

Question 5

What is the primary reason CKA candidates are advised to practice with vim or nano before the exam?

Accepted Answer

YAML manifests must be written and edited in a terminal text editor during the performance-based exam

Answer

Since the CKA is entirely terminal-based, candidates must edit YAML files using a terminal text editor like vim or nano.
