最新的 Kubernetes Cloud Native Associate KCNA 免費考試真題 (Q231-Q236):

問題 #231
What standard does kubelet use to communicate with the container runtime?

A. CRI-O
B. Container Runtime Interface (CRI)
C. ContainerD
D. Service Mesh Interface (SMI)

答案：B

解題說明：
kubelet can communicate with any runtime that supports the CRI standard.

問題 #232
Explain the difference between a Deployment and a StatefulSet in Kubernetes.

A. Deployments are used for managing the lifecycle of a single Pod, while StatefulSets manage multiple Pods.
B. Deployments are responsible for scheduling Pods, while StatefulSets manage the lifecycle of Services.
C. Deployments are used for stateless applications, while StatefulSets are used for stateful applications that require persistent storage and unique identities.
D. Deployments are used for deploying and managing stateless applications, while StatefulSets are used for deploying and managing stateful applications.
E. Deployments handle rolling updates, while StatefulSets only support manual updates.

答案：C,D

解題說明：
Deployments are used for deploying and managing stateless applications, while StatefulSets are used for deploying and managing stateful applications. Deployments are ideal for applications where the state of each Pod is not important, while StatefulSets are designed for applications that require persistent storage, unique network identities, and ordered scaling.

問題 #233
You have configured Prometheus to scrape metrics from a Kubernetes cluster, but you notice that some pods are not being scraped. You suspect that the Prometheus server might be experiencing resource constraints. How can you troubleshoot this issue?

A. Examine the Prometheus server's CPU and memory usage to identify any resource bottlenecks.
B. Use the Prometheus •status/targets• endpoint to see which targets are currently being scraped and any errors encountered.
C. Check the Prometheus logs for any errors related to scraping or resource limitations.
D. Verify the Prometheus server's configuration and ensure that the scraping interval and target labels are correct.
E. All of the above

答案：A,B,C,D,E

解題說明：
All of the mentioned options are valuable for troubleshooting scraping issues caused by resource constraints. Checking logs, monitoring server resource usage, reviewing configuration, and using the 'status/targetS endpoint provide comprehensive insights into the problem. By investigating these aspects, you can pinpoint the root cause and take appropriate actions to resolve the issue.

問題 #234
Which of the following is a recommended security habit in Kubernetes?

A. Run the containers as the user with group ID 0 (root) and any user ID.
B. Allow privilege escalation from within a container as the default option.
C. Run the containers as the user with user ID 0 (root) and any group ID.
D. Disallow privilege escalation from within a container as the default option.

答案：D

解題說明：
The correct answer is B. A widely recommended Kubernetes security best practice is to disallow privilege escalation inside containers by default. In Kubernetes Pod/Container security context, this is represented by allowPrivilegeEscalation: false. This setting prevents a process from gaining more privileges than its parent process-commonly via setuid/setgid binaries or other privilege-escalation mechanisms. Disallowing privilege escalation reduces the blast radius of a compromised container and aligns with least-privilege principles.
Options A and C are explicitly unsafe because they encourage running as root (UID 0 and/or GID 0). Running containers as root increases risk: if an attacker breaks out of the application process or exploits kernel/runtime vulnerabilities, having root inside the container can make privilege escalation and lateral movement easier. Modern Kubernetes security guidance strongly favors running as non-root (runAsNonRoot: true, explicit runAsUser), dropping Linux capabilities, using read-only root filesystems, and applying restrictive seccomp/AppArmor/SELinux profiles where possible.
Option D is the opposite of best practice. Allowing privilege escalation by default increases the attack surface and violates the idea of secure defaults.
Operationally, this habit is often enforced via admission controls and policies (e.g., Pod Security Admission in "restricted" mode, or policy engines like OPA Gatekeeper/Kyverno). It's also important for compliance: many security baselines require containers to run as non-root and to prevent privilege escalation.
So, the recommended security habit among the choices is clearly B: Disallow privilege escalation.

問題 #235
What is a DaemonSet?

A. It's a type of workload that needs to be run periodically on a given schedule.
B. It's a type of workload that provides guarantees about ordering, uniqueness, and identity of a set of Pods.
C. It's a type of workload responsible for maintaining a stable set of replica Pods running in any node.
D. It's a type of workload that ensures a specific set of nodes run a copy of a Pod.

答案：D
