Linux Foundation Kubernetes and Cloud Native Associate 認定 KCNA 試験問題 (Q44-Q49):

質問 # 44

  • D. Create images, scale, and manage the health of containers.

正解：A


質問 # 45
What is the role of the ingressClassName field in a Kubernetes Ingress resource?

  • A. It defines the type of protocol (HTTP or HTTPS) that the Ingress Controller should process.
  • B. It specifies the backend Service used by the Ingress Controller to route external requests.
  • C. It determines how routing rules are prioritized when multiple Ingress objects are applied.
  • D. It indicates which Ingress Controller should implement the rules defined in the Ingress resource.

正解：D

解説：
The ingressClassName field in a Kubernetes Ingress resource is used to explicitly specify which Ingress Controller is responsible for processing and enforcing the rules defined in that Ingress. This makes option D the correct answer.
In Kubernetes clusters, it is common to have multiple Ingress Controllers running at the same time. For example, a cluster might run an NGINX Ingress Controller, a cloud-provider-specific controller, and an internal-only controller simultaneously. Without a clear mechanism to select which controller should handle a given Ingress resource, multiple controllers could attempt to process the same rules, leading to conflicts or undefined behavior.
The ingressClassName field solves this problem by referencing an IngressClass object. The IngressClass defines the controller implementation (via the controller field), and the Ingress resource uses ingressClassName to declare which class-and therefore which controller-should act on it. This creates a clean and explicit binding between an Ingress and its controller.
Option A is incorrect because protocol handling (HTTP vs HTTPS) is defined through TLS configuration and service ports, not by ingressClassName. Option B is incorrect because backend Services are defined in the rules and backend sections of the Ingress specification. Option C is incorrect because routing priority is determined by path matching rules and controller-specific logic, not by ingressClassName.
Historically, annotations were used to select Ingress Controllers, but ingressClassName is now the recommended and standardized approach. It improves clarity, portability, and compatibility across different Kubernetes distributions and controllers.
In summary, the primary purpose of ingressClassName is to indicate which Ingress Controller should implement the routing rules for a given Ingress resource, making Option D the correct and verified answer.


質問 # 46
What feature must a CNI support to control specific traffic flows for workloads running in Kubernetes?

  • A. IP Address Management
  • B. Network Policies
  • C. Pod Security Policy
  • D. Border Gateway Protocol

正解：B

解説：
To control which workloads can communicate with which other workloads in Kubernetes, you use NetworkPolicy resources-but enforcement depends on the cluster's networking implementation. Therefore, for traffic-flow control, the CNI/plugin must support Network Policies, making D correct.
Kubernetes defines the NetworkPolicy API as a declarative way to specify allowed ingress and egress traffic based on selectors (Pod labels, namespaces, IP blocks) and ports/protocols. However, Kubernetes itself does not enforce NetworkPolicy rules; enforcement is provided by the network plugin (or associated dataplane components). If your CNI does not implement NetworkPolicy, the objects may exist in the API but have no effect-Pods will communicate freely by default.
Option B (IP Address Management) is often part of CNI responsibilities, but IPAM is about assigning addresses, not enforcing L3/L4 security policy. Option A (BGP) is used by some CNIs to advertise routes (for example, in certain Calico deployments), but BGP is not the general requirement for policy enforcement.
Option C (Pod Security Policy) is a deprecated/removed Kubernetes admission feature related to Pod security settings, not network flow control.
From a Kubernetes security standpoint, NetworkPolicies are a key tool for implementing least privilege at the network layer-limiting lateral movement, reducing blast radius, and segmenting environments. But they only work when the chosen CNI supports them. Thus, the correct answer is D: Network Policies.
=========


質問 # 47
You need to deploy a pod that requires access to a specific GPU device. How can you ensure that
the pod is scheduled on a node with the required GPU?

  • A. Use the 'tolerations' field to tolerate the 'GPU' taint.
  • B. Use the 'nodeSelector' field to target nodes with the 'gpu' label.
  • C. Use the 'podAffinity' field to group pods with GPU requirements together.
  • D. Use the 'affinity' field to prefer nodes with the 'GPU* label.
  • E. Use the 'resources' field to specify the GPU requirements in the container's definition.

正解：E

解説：
You can use both the •nodeselector• and •resources' fields to achieve this: 'nodeselector•: Targets nodes with a label indicating the presence of GPUs (e.g., •gpu: true). •resources': Specify the GPU resource requirements within the container's definition. This provides a more precise way to request specific GPUs and their capabilities. While •tolerations' and 'affinity' can be used for other scheduling needs, they are not directly designed for GPU resource allocation.


質問 # 48
What edge and service proxy tool is designed to be integrated with cloud native applications?

  • A. Envoy
  • B. CoreDNS
  • C. CNI
  • D. gRPC

正解：A

解説：
The correct answer is D: Envoy. Envoy is a high-performance edge and service proxy designed for cloud-native environments. It is commonly used as the data plane in service meshes and modern API gateways because it provides consistent traffic management, observability, and security features across microservices without requiring every application to implement those capabilities directly.
Envoy operates at Layer 7 (application-aware) and supports protocols like HTTP/1.1, HTTP/2, gRPC, and more. It can handle routing, load balancing, retries, timeouts, circuit breaking, rate limiting, TLS termination, and mutual TLS (mTLS). Envoy also emits rich telemetry (metrics, access logs, tracing) that integrates well with cloud-native observability stacks.
Why the other options are incorrect:
CoreDNS (A) provides DNS-based service discovery within Kubernetes; it is not an edge/service proxy.
CNI (B) is a specification and plugin ecosystem for container networking (Pod networking), not a proxy.
gRPC (C) is an RPC protocol/framework used by applications; it's not a proxy tool. (Envoy can proxy gRPC traffic, but gRPC itself isn't the proxy.) In Kubernetes architectures, Envoy often appears in two places: (1) at the edge as part of an ingress/gateway layer, and (2) sidecar proxies alongside Pods in a service mesh (like Istio) to standardize service-to-service communication controls and telemetry. This is why it is described as "designed to be integrated with cloud native applications": it's purpose-built for dynamic service discovery, resilient routing, and operational visibility in distributed systems.
So the verified correct choice is D (Envoy).
