질문 # 13
Which one of the following best describes the role Cilium provides in Kubernetes?
정답：D
설명：
Technical explanation
Cilium functions as a Kubernetes Container Network Interface implementation. When Kubernetes creates or removes a pod sandbox, the container runtime invokes the configured CNI plugin. Cilium establishes the pod' s network connectivity, connects the workload to the node's networking environment, allocates or obtains an address through the configured IPAM mode, and coordinates the endpoint with the Cilium agent. Its eBPF datapath then supplies routing, service load balancing, policy enforcement, and network visibility.
Cilium provides substantially more functionality than the minimum CNI contract, but those additional capabilities do not change its primary Kubernetes networking role. Hubble supplies integrated network observability, yet Cilium is not merely a container-metrics monitor. Resource utilization such as CPU and memory is normally handled through Kubernetes metrics and monitoring systems.
Cilium is also not a Container Storage Interface. CSI drivers manage storage volumes, attachment, mounting, and lifecycle operations, which are unrelated to Cilium's primary responsibilities. Nor is Cilium simply a pod- operation logging mechanism. It can emit datapath events and diagnostic logs, but those are supporting capabilities.
Accordingly, D provides the correct architectural classification for Cilium in a Kubernetes cluster.

질문 # 14
If you are required to block ingress traffic from external IPs for all pods in your cluster, which of the following network policies would be the best fit?
정답：A
설명：
Technical explanation
A cluster-wide requirement is best implemented with CiliumClusterwideNetworkPolicy , whose correct resource spelling is CiliumClusterwideNetworkPolicy . Unlike a namespaced CiliumNetworkPolicy , this Cilium CRD is non-namespaced and can select endpoints across the entire cluster.
To deny external ingress for every Cilium-managed pod, a cluster-wide policy can use an empty endpointSelector and an ingressDeny rule selecting the world entity. Cilium defines world as network endpoints outside the cluster. An alternative allow-list construction can permit only the cluster entity, thereby excluding external sources, but an explicit deny rule usually communicates the requirement more directly.
A standard Kubernetes NetworkPolicy and a CiliumNetworkPolicy are namespaced, requiring repeated resources in every applicable namespace. CiliumGlobalPolicy is not a valid Cilium resource type. Although the option capitalizes "Wide" differently from the actual kind, D unmistakably identifies the intended cluster- scoped policy.

질문 # 15
What is correct about this Cilium Network Policy?
Question 21 Cilium Network Policy exhibit
정답：A
설명：
Technical explanation
The intended policy selects every Cilium-managed endpoint in the namespace where the CiliumNetworkPolicy is created because endpointSelector: {} is empty. The manifest does not specify metadata.namespace ; if it is applied normally in the default namespace, the selected endpoints are therefore all pods in default , not pods across every namespace. The egress destination selector identifies pods in kube- system carrying k8s-app: kube-dns , while matchPattern: "*" allows all DNS query names handled by the DNS rule. This supports the intended answer A.
There is, however, a material defect in the exhibit: toPorts is a list in the Cilium policy schema, but the image shows rules directly beneath toPorts without a preceding list marker. The official form is toPorts: , followed by - ports: and rules: within that list item. Port 53 and its protocol should also be stated explicitly. Exactly as displayed, the manifest should not be treated as a valid deployable policy.
The question should be corrected before examination use. Once the missing list item and port definition are restored, A accurately describes its scope and effect.

질문 # 16
What is NOT a valid description of the sidecar-based model?
정답：D
설명：
Technical explanation
C is not a valid description. A service-mesh sidecar externalizes networking functions into a proxy container running beside the application; it does not force the instrumentation logic into the application's source code.
In fact, a core service-mesh objective is to provide connectivity, security, traffic management, and observability transparently without requiring application-code changes.
The operational concerns in the other choices are characteristic of sidecar implementations. A proxy must be injected into each workload pod, increasing container count and potentially affecting pod initialization, resource consumption, ordering, and readiness. Adding a sidecar to an existing pod template normally requires the pods to be recreated because Kubernetes cannot dynamically add a new container to an already- running pod.
Traffic interception also directs application traffic through the sidecar proxy and its network namespace paths, adding network-stack traversal and proxy-processing overhead. Cilium's service-mesh design can instead use node-level Envoy proxies together with eBPF traffic redirection, avoiding one proxy container in every application pod. This preserves transparent application behavior while reducing the per-workload operational burden.

질문 # 17
Which Cilium configuration is recommended to help identify the correct configuration of network policies without interrupting workload communications?
정답：B
설명：
Technical explanation
Policy Audit Mode allows administrators to evaluate the consequences of network policies before enforcing their deny decisions. Traffic that would ordinarily be rejected remains permitted, while Cilium records an audit verdict. These verdicts can be examined with Cilium monitoring tools and used to identify legitimate communications that are missing from the proposed policies.
This is especially valuable when introducing host policies or default-deny controls into an existing environment. An incomplete policy might otherwise block access to the Kubernetes API, node-management interfaces, DNS, monitoring systems, or other operational dependencies. The recommended workflow is to enable audit mode, observe traffic and policy verdicts, adjust the rules, confirm that all required communications receive allow verdicts, and then disable audit mode to begin enforcement.
DNS enforcement mode and HTTP audit mode are not the general Cilium configuration requested. "Policy enforcement mode" describes whether policies are normally enforced, but it does not provide the non- disruptive learning behavior in the question.
Audit mode should be treated as a temporary validation mechanism because it does not actually block disallowed traffic and does not persist across every agent-restart scenario.
