Linux Foundation Kubernetes and Cloud Native Associate 認定 KCNA 試験問題 (Q33-Q38):

質問 # 33
You are monitoring a Kubernetes cluster using Prometheus. You notice a significant spike in CPUusage on a specific pod. To investigate further, you want to collect metrics related to individual processes running within that pod. Which Prometheus query can effectively achieve this?

正解：A

解説：
The query •process_cpu_seconds_total{pod="", container="", process=""Y is designed to retrieve CPU usage metrics for specific processes running within a container. The other options are not focused on individual process metrics.


質問 # 34
What can you use to add new resource types to your cluster?

正解：D

解説：

質問 # 35
Which of the following is NOT a Kubernetes component?

正解：B

解説：
Docker is not a Kubernetes component.


質問 # 36
What is the purpose of the kube-proxy?

正解：D

解説：
The correct answer is B: kube-proxy maintains network rules on nodes. kube-proxy is a node component that implements part of the Kubernetes Service abstraction. It watches the Kubernetes API for Service and EndpointSlice/Endpoints changes, and then programs the node's dataplane rules (commonly iptables or IPVS
, depending on configuration) so that traffic sent to a Service virtual IP and port is correctly forwarded to one of the backing Pod endpoints.
This is how Kubernetes provides stable Service addresses even though Pod IPs are ephemeral. When Pods scale up/down or are replaced during a rollout, endpoints change; kube-proxy updates the node rules accordingly. From the perspective of a client, the Service name and ClusterIP remain stable, while the actual backend endpoints are load-distributed.
Option A is a tempting phrasing but incomplete: load distribution is an outcome of the forwarding rules, but kube-proxy's primary role is maintaining the network forwarding rules that make Services work. Option C is incorrect because internet connectivity depends on cluster networking, routing, NAT, and often CNI configuration-not kube-proxy's job description. Option D is incorrect because DNS is typically handled by CoreDNS; kube-proxy does not "maintain DNS rules." Operationally, kube-proxy failures often manifest as Service connectivity issues: Pod-to-Service traffic fails, ClusterIP routing breaks, NodePort behavior becomes inconsistent, or endpoints aren't updated correctly.
Modern Kubernetes environments sometimes replace kube-proxy with eBPF-based dataplanes, but in the classic architecture the correct statement remains: kube-proxy runs on each node and maintains the rules needed for Service traffic steering.
=========


質問 # 37
You are configuring a Kubernetes cluster for a microservices-based application. Each microservice needs its own network namespace and isolated communication. Which Kubernetes networking feature would you use to achieve this?

正解：A

解説：
NetworkPolicy is the Kubernetes feature designed for controlling network traffic between pods and external sources. It allows you to define rules to allow or deny specific network communication based on source, destination, ports, and other criteria. This helps isolate microservices and enforce network segmentation within the cluster.
