최신 Kubernetes Cloud Native Associate KCNA 무료샘플문제 (Q12-Q17):

질문 # 12
What kind of limitation cgroups allows?

A. Accounting
B. Resource limiting
C. Prioritization
D. Control
E. Server cpu and memory
F. None of the options

정답：A,B,C,D

질문 # 13
A Pod was created that shows the ErrImagePull status. What is most the cause of the error?

A. The container image needs to run using hostNetwork.
B. The container image cannot be downloaded.
C. Kube-scheduler cannot find a node to execute the Pod.
D. Kubelet is not running properly on the node.

정답：B

설명：
ErrImagePull indicates that the kubelet attempted to pull the container image but failed, typically due to an incorrect image name, missing repository access, or authentication issues preventing the image from being downloaded.

질문 # 14
Which of the following statements is correct concerning Open Policy Agent (OPA)?

A. It cannot be used outside Kubernetes.
B. Policies can only be tested when published.
C. The policies must be written in Python language.
D. Kubernetes can use it to validate requests and apply policies.

정답：D

설명：
Open Policy Agent (OPA) is a general-purpose policy engine used to define and enforce policy across different systems. In Kubernetes, OPA is commonly integrated through admission control (often via Gatekeeper or custom admission webhooks) to validate and/or mutate requests before they are persisted in the cluster. This makes B correct: Kubernetes can use OPA to validate API requests and apply policy decisions.
Kubernetes' admission chain is where policy enforcement naturally fits. When a user or controller submits a request (for example, to create a Pod), the API server can call external admission webhooks. Those webhooks can evaluate the request against policy-such as "no privileged containers," "images must come from approved registries," "labels must include cost-center," or "Ingress must enforce TLS." OPA's policy language (Rego) allows expressing these rules in a declarative form, and the decision ("allow/deny" and sometimes patches) is returned to the API server. This enforces governance consistently and centrally.
Option A is incorrect because OPA policies are written in Rego, not Python. Option C is incorrect because policies can be tested locally and in CI pipelines before deployment; in fact, testability is a key advantage. Option D is incorrect because OPA is designed to be platform-agnostic-it can be used with APIs, microservices, CI/CD pipelines, service meshes, and infrastructure tools, not only Kubernetes.
From a Kubernetes fundamentals view, OPA complements RBAC: RBAC answers "who can do what to which resources," while OPA-style admission policies answer "even if you can create this resource, does it meet our organizational rules?" Together they help implement defense in depth: authentication + authorization + policy admission + runtime security controls. That is why OPA is widely used to enforce security and compliance requirements in Kubernetes environments.

질문 # 15
You have a microservice that relies on a separate authentication service. You want to implement fine-grained authorization using Istio based on request attributes like user roles or specific headers. What Istio feature would you use?

A. Istio's 'Telemetry' feature
B. Istio's 'RequestAuthentication' feature
C. Istio's 'ServiceEntry' feature
D. Istio's 'TrafficManagement' feature
E. Istio's 'AuthorizationPolicy' feature

정답：E

설명：
Istio's AuthonzationPolicy feature allows you to define granular authorization rules based on request attributes, including headers, user identities, and other context. This enables you to control access to microservices based on specific conditions. Option A is for authentication, not authorization. Option C is for traffic management. Option D is for telemetry. Option E is for service discovery and configuration.

질문 # 16
If a Pod was waiting for container images to download on the scheduled node, what state would it be in?

A. Pending
B. Failed
C. Unknown
D. Succeeded

정답：A

설명：
If a Pod is waiting for its container images to be pulled to the node, it remains in the Pending phase, so D is correct. Kubernetes Pod "phase" is a high-level summary of where the Pod is in its lifecycle. Pending means the Pod has been accepted by the cluster but one or more of its containers has not started yet. That can occur because the Pod is waiting to be scheduled, waiting on volume attachment/mount, or-very commonly- waiting for the container runtime to pull the image.
When image pulling is the blocker, kubectl describe pod <name> usually shows events like "Pulling image
..." and "Successfully pulled image ..." or failures like ImagePullBackOff/ErrImagePull. Even if the node has been assigned (scheduler has set spec.nodeName), the Pod can still be Pending while kubelet and the runtime perform preparation steps.
Why the other phases don't apply:
* Succeeded is for run-to-completion Pods that have finished successfully (typical for Jobs).
* Failed means the Pod terminated and at least one container terminated in failure (and won't be restarted, depending on restartPolicy).
* Unknown is used when the node can't be contacted and the Pod's state can't be reliably determined (rare in healthy clusters).
A subtle but important Kubernetes detail: status "Waiting" reasons like ImagePullBackOff are container states inside .status.containerStatuses, while the Pod phase can still be Pending. So, "waiting for images to download" maps to Pod Pending, with container waiting reasons providing the deeper diagnosis.
Therefore, the verified correct answer is D: Pending.
