最新的 Kubernetes Cloud Native Associate KCNA 免費考試真題 (Q174-Q179):

問題 #174
Which of the following systems is NOT compatible with the CRI runtime interface standard?
(Typo corrected: "CRI-0" # "CRI-O")

答案：D

解題說明：
Kubernetes uses the Container Runtime Interface (CRI) to support pluggable container runtimes. The kubelet talks to a CRI-compatible runtime via gRPC, and that runtime is responsible for pulling images and running containers. In this context, containerd and CRI-O are CRI-compatible container runtimes (or runtime stacks) used widely with Kubernetes, and dockershim historically served as a compatibility layer that allowed kubelet to talk to Docker Engine as if it were CRI (before dockershim was removed from kubelet in newer Kubernetes versions). That leaves systemd as the correct "NOT compatible with CRI" answer, so C is correct.
systemd is an init system and service manager for Linux. While it can be involved in how services (like kubelet) are started and managed on the host, it is not a container runtime implementing CRI. It does not provide CRI gRPC endpoints for kubelet, nor does it manage containers in the CRI sense.
The deeper Kubernetes concept here is separation of responsibilities: kubelet is responsible for Pod lifecycle at the node level, but it delegates "run containers" to a runtime via CRI. Runtimes like containerd and CRI-O implement that contract; Kubernetes can swap them without changing kubelet logic. Historically, dockershim translated kubelet's CRI calls into Docker Engine calls. Even though dockershim is no longer part of kubelet, it was still "CRI-adjacent" in purpose and often treated as compatible in older curricula.
Therefore, among the provided options, systemd is the only one that is clearly not a CRI-compatible runtime system, making C correct.

問題 #175
A site reliability engineer needs to temporarily prevent new Pods from being scheduled on node-2 while keeping the existing workloads running without disruption. Which kubectl command should be used?

答案：B

解題說明：
In Kubernetes, node maintenance and availability are common operational tasks, and the platform provides specific commands to control how the scheduler places Pods on nodes. When the requirement is to temporarily prevent new Pods from being scheduled on a node without affecting the currently running Pods
, the correct approach is to cordon the node.
The command kubectl cordon node-2 marks the node as unschedulable. This means the Kubernetes scheduler will no longer place any new Pods onto that node. Importantly, cordoning a node does not evict, restart, or interrupt existing Pods. All workloads already running on the node continue operating normally. This makes cordoning ideal for scenarios such as diagnostics, monitoring, or preparing for future maintenance while ensuring zero workload disruption.
Option B, kubectl delete node-2, is incorrect because deleting a node removes it entirely from the cluster. This action would cause Pods running on that node to be terminated and rescheduled elsewhere, resulting in disruption-exactly what the question specifies must be avoided.
Option C, kubectl drain node-2, is also incorrect in this context. Draining a node safely evicts Pods (except for certain exclusions like DaemonSets) and reschedules them onto other nodes. While drain is useful for maintenance and upgrades, it does not keep existing workloads running on the node, making it unsuitable here.
Option D, kubectl pause deployment, applies only to Deployments and merely pauses rollout updates. It does not affect node-level scheduling behavior and has no impact on where Pods are placed by the scheduler.
Therefore, the correct and verified answer is Option A: kubectl cordon node-2, which aligns with Kubernetes operational best practices and official documentation for non-disruptive node management.


問題 #176
You are using a Kubernetes admission controller to enforce security policies. Which of the following admission controller configurations is MOST appropriate for preventing pods from running with the "-privileged" flag?

答案：C

解題說明：
Option E is the most appropriate configuration for preventing pods from running with the '-privileged' flag. This configuration defines a ValidatingAdmissionPolicy named 'privileged-pod-policy' that specifically targets pod creation operations ('CREATE'). It checks the 'securityContext' field of the pod spec and ensures that the 'privileged' field is set to 'false". By enforcing this rule, the admission controller will block any attempt to create pods with the privileged" flag, enhancing the security of your Kubernetes cluster.


問題 #177
You are using Prometheus to monitor your Kubernetes cluster. You notice that several pods are
experiencing high memory usage. You want to investigate further to determine which containers within these pods are consuming the most memory. How can you effectively use Prometheus to identify these memory-intensive containers?

答案：C,D

解題說明：
Both options B and D provide effective solutions for identifying memory-intensive containers. Option B allows you to directly analyze the 'kube_pod_container_status_memory_usage_bytes• metric, which provides the actual memory usage of each container within the pod. Option D suggests filtering Prometheus queries by container name and sorting by memory usage, enabling you to easily pinpoint containers with the highest memory consumption. While option A provides information about requested memory limits, it doesn't directly reflect the actual memory usage. Options C and E are not directly relevant to identifying memory-intensive containers.


問題 #178
What are the initial namespaces that Kubernetes starts with?

答案：A

解題說明：
Kubernetes creates a set of namespaces by default when a cluster is initialized. The standard initial namespaces are default, kube-system, kube-public, and kube-node-lease, making A correct.
* default is the namespace where resources are created if you don't specify another namespace. Many quick-start examples deploy here, though production environments typically use dedicated namespaces per app/team.
* kube-system contains objects created and managed by Kubernetes system components (control plane add-ons, system Pods, controllers, DNS components, etc.). It's a critical namespace, and access is typically restricted.
* kube-public is readable by all users (including unauthenticated users in some configurations) and is intended for public cluster information, though it's used sparingly in many environments.
* kube-node-lease holds Lease objects used for node heartbeats. This improves scalability by reducing load on etcd compared to older heartbeat mechanisms and helps the control plane track node liveness efficiently.
The incorrect options contain non-standard namespace names like "system," "kube-main," or "kube-primary," and "kube-default" is not a real default namespace. Kubernetes' built-in namespace set is well-documented and consistent with typical cluster bootstraps.
Understanding these namespaces matters operationally: system workloads and controllers often live in kube- system, and many troubleshooting steps involve inspecting Pods and events there. Meanwhile, kube-node- lease is key to node health tracking, and default is the catch-all if you forget to specify -n.
So, the verified answer is A: default, kube-system, kube-public, kube-node-lease.
