Administration, API Objects, Labels and Namespaces
Associate-level administration tests Kubernetes API objects, YAML intent, labels, selectors, namespaces, access boundaries, and object lifecycle vocabulary.
How to study for Kubernetes and Cloud Native Associate
Treat each question as a foundation check: identify the Kubernetes primitive, connect it to the cloud native pattern, then choose the least surprising operational behavior.
Core concepts
Concept 1
Kubernetes objects combine API identity and metadata with a desired spec and controller-reported status.
Exam cue: Identify whether the request is get, list, watch, create, update, patch, delete, or a subresource action.
Concept 2
Labels drive selection, annotations hold non-identifying metadata, and Namespaces scope namespaced resources and policy.
Exam cue: Check resource kind, Namespace, labels, selector, and current context before acting.
Concept 3
kubectl is an API client; safe administration preserves declarative source, previews changes, and follows authorization boundaries.
Exam cue: For configuration, distinguish ConfigMap, Secret, manifest field, and client kubeconfig.
Risk pitfalls and guardrails
Parsing human-oriented tables in automation when structured JSON is available.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Assuming read permission implies update or delete permission on the same resource.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Making lasting production edits outside the reviewed declarative source of truth.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Declarative Object
A declarative object records desired state so Kubernetes controllers can reconcile behavior.
Manifest
A manifest describes Kubernetes resources in YAML or JSON for creation or update.
Label
A label is key-value metadata used to organize and select Kubernetes objects.
Selector
A selector matches labels so controllers, Services, and policies can target objects.
Annotation
An annotation stores non-identifying metadata used by tools, controllers, or humans.
Resource Quota
A ResourceQuota limits aggregate resource usage within a namespace.
Kubectl
kubectl is the common command-line client for reading and changing Kubernetes API objects.
Object Lifecycle
Object lifecycle means create, inspect, update, scale, replace, delete, and verify resources.
ConfigMap
A ConfigMap separates non-secret configuration from the container image and workload template.
ServiceAccount
A ServiceAccount gives a Pod a namespaced workload identity for Kubernetes API access.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
