Linux Foundation Kubernetes and Cloud Native Associate 認定 KCNA 試験問題 (Q291-Q296):

質問 # 291
There are three Nodes in a cluster, and want to run exactly one replica of a Pod on each Node. Pre-fer to automatically create a replica on any new Nodes when they are added. Which Kubernetes re-source should you use?

A. ReplicaSet
B. StatefulSet
C. DaemonSet
D. NodeSet
E. Deployment

正解：C

解説：
https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/
A DaemonSet runs replicas on all (or just some) Nodes in the cluster.

質問 # 292
Continuous delivery is ______.

A. Manually deploying the code
B. Automatically deploying code to [container or server] environment
C. Coding, Building and Testing the code

正解：B

質問 # 293
Manual reclamation policy of a PVC resource is known as:

A. Delete
B. Retain
C. claimRef
D. Recycle

正解：B

質問 # 294
Which of the following scenarios would benefit the most from a service mesh architecture?

A. Tens of distributed applications running in multiple clusters, each one providing multiple services.
B. Thousands of distributed applications running in a single cluster, each one providing multiple services.
C. A few applications with hundreds of Pod replicas running in multiple clusters, each one providing multiple services.
D. Thousands of distributed applications running in multiple clusters, each one providing multiple services.

正解：D

解説：
A service mesh is most valuable when service-to-service communication becomes complex at large scale-many services, many teams, and often multiple clusters. That's why D is the best fit: thousands of distributed applications across multiple clusters. In that scenario, the operational burden of securing, observing, and controlling east-west traffic grows dramatically. A service mesh (e.g., Istio, Linkerd) addresses this by introducing a dedicated networking layer (usually sidecar proxies such as Envoy) that standardizes capabilities across services without requiring each application to implement them consistently.
The common "mesh" value-adds are: mTLS for service identity and encryption, fine-grained traffic policy (retries, timeouts, circuit breaking), traffic shifting (canary, mirroring), and consistent telemetry (metrics, traces, access logs). Those features become increasingly beneficial as the number of services and cross-service calls rises, and as you add multi-cluster routing, failover, and policy management across environments. With thousands of applications, inconsistent libraries and configurations become a reliability and security risk; the mesh centralizes and standardizes these behaviors.
In smaller environments (A or C), you can often meet requirements with simpler approaches: Kubernetes Services, Ingress/Gateway, basic mTLS at the edge, and application-level libraries. A single large cluster (B) can still benefit from a mesh, but adding multiple clusters increases complexity: traffic management across clusters, identity trust domains, global observability correlation, and consistent policy enforcement. That's where mesh architectures typically justify their additional overhead (extra proxies, control plane components, operational complexity).
So, the "most benefit" scenario is the largest, most distributed footprint-D.

質問 # 295
The Container Runtime Interface (CRI) defines the protocol for the communication between:

A. The kubelet and the container runtime.
B. The container runtime and the image registry.
C. The container runtime and etcd.
D. The kube-apiserver and the kubelet.

正解：A
