Preparation and Study Resources Flashcards

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

Answer: kubeadm init

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

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

Answer: Role and RoleBinding

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

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

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

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

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

Answer: killer.sh CKA simulator

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

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

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

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

Which kubectl explain subcommand feature helps candidates quickly look up API field definitions without leaving the terminal?

Answer: kubectl explain --recursive

`kubectl explain --recursive` prints the full field tree of any Kubernetes resource, useful when you can't remember a spec field.

How many attempts are included in the CKA exam registration fee if a candidate fails on the first try?

Answer: One free retake

The CKA registration includes one free retake if the candidate does not pass on the first attempt.
