최신 Kubernetes Cloud Native Associate KCNA 무료샘플문제 (Q148-Q153):

질문 # 148
You are building a cloud-native application that uses a combination of Kubernetes, Istio, and Prometheus. You want to ensure that your application's logs, metrics, and traces are correlated for easy troubleshooting. What approach would you take to achieve this correlation?

정답：A

설명：
The correct answer is B . Istio's Mixer allows you to integrate Jaeger with Istio and Prometheus. This integration enables you to enrich tracing data with relevant metrics and log information captured from Istio's traffic management capabilities. This approach provides a unified platform for correlating logs, metrics, and traces. The other options are not as effective for achieving correlation: A : This approach focuses only on logs and does not provide a way to link logs to metrics or traces. C : While Istio can capture logs, sending them to Prometheus is not an ideal solution for correlation. D : A centralized logging system like Fluentd can collect logs, but it does not inherently provide mechanisms to correlate them with metrics or traces. E : Manually correlating logs, metrics, and traces using 'kubectl logs is tedious and prone to errors, especially in a dynamic environment like Kubernetes.


질문 # 149
Explain the concept of "service discovery" in Prometheus and how it integrates with Kubernetes.

정답：B

설명：
Service discovery in Prometheus enables it to locate and collect metrics from dynamic Kubernetes environments. It automatically discovers and configures scraping targets based on Kubernetes service definitions. This simplifies the monitoring process and ensures that Prometheus stays up-to-date with changes in the Kubernetes cluster.


질문 # 150
In the Kubernetes platform, which component is responsible for running containers?

정답：A

설명：
In Kubernetes, the actual act of running containers on a node is performed by the container runtime. The kubelet instructs the runtime via CRI, and the runtime pulls images, creates containers, and manages their lifecycle. Among the options provided, CRI-O is the only container runtime, so B is correct.
It's important to be precise: the component that "runs containers" is not the control plane and not etcd. etcd (option A) stores cluster state (API objects) as the backing datastore. It never runs containers. cloud-controller-manager (option C) integrates with cloud APIs for infrastructure like load balancers and nodes. kube-controller-manager (option D) runs controllers that reconcile Kubernetes objects (Deployments, Jobs, Nodes, etc.) but does not execute containers on worker nodes.
CRI-O is a CRI implementation that is optimized for Kubernetes and typically uses an OCI runtime (like runc) under the hood to start containers. Another widely used runtime is containerd. The runtime is installed on nodes and is a prerequisite for kubelet to start Pods. When a Pod is scheduled to a node, kubelet reads the PodSpec and asks the runtime to create a "pod sandbox" and then start the container processes. Runtime behavior also includes pulling images, setting up namespaces/cgroups, and exposing logs/stdout streams back to Kubernetes tooling.
So while "the container runtime" is the most general answer, the question's option list makes CRI-O the correct selection because it is a container runtime responsible for running containers in Kubernetes.


질문 # 151
Which command lists the running containers in the current Kubernetes namespace?

정답：A

설명：
The correct answer is A: kubectl get pods. Kubernetes does not manage "containers" as standalone top-level objects; the primary schedulable unit is the Pod, and containers run inside Pods. Therefore, the practical way to list what's running in a namespace is to list the Pods in that namespace. kubectl get pods shows Pods and their readiness, status, restarts, and age-giving you the canonical view of running workloads.
If you need the container-level details (images, container names), you typically use additional commands and output formatting:
kubectl describe pod <pod> to view container specs, images, states, and events kubectl get pods -o jsonpath=... or -o wide to surface more fields kubectl get pods -o=json to inspect .spec.containers and .status.containerStatuses But among the provided options, kubectl get pods is the only real kubectl command that lists the running workload objects in the current namespace.
The other options are not valid kubectl subcommands: kubectl ls, kubectl ps, and kubectl show pods are not standard Kubernetes CLI operations. Kubernetes intentionally centers around the API resource model, so listing resources uses kubectl get <resource>. This also aligns with Kubernetes' declarative nature: you observe and manage the state via API objects, not by directly enumerating OS-level processes.
So while the question says "running containers," the Kubernetes-correct interpretation is "containers in running Pods," and the appropriate listing command in the namespace is kubectl get pods, option A.


질문 # 152
You have a Kubernetes cluster with multiple namespaces. You are running different applications in separate namespaces and want to ensure that HPAs in each namespace are not interfering with each other. Which of the following measures should you take?

정답：B,C

설명：
You need to ensure that HPAs are not competing for resources across namespaces- Resource quotas (C) limit resource consumption within each namespace, preventing HPAs from consuming resources intended for other applications. A custom controller (D) can be used to manage HPAs across multiple namespaces, coordinating scaling decisions to avoid resource contention and optimize utilization across the cluster. While options A and B might seem relevant, they are not effective solutions for preventing interference between HPAs in different namespaces. Option E is incorrect; HPAs operate within their namespaces, but resource contention can occur if not managed properly.
