質問 # 43
Which component manages the allocation of per-node PodCIDRs in the cluster-scope IPAM (IP address management) mode?
正解：A
解説：
Technical explanation
In cluster-scope IPAM, the Cilium Operator allocates a PodCIDR to each node from the configured cluster- wide address pool. It records those allocations in each node's CiliumNode custom resource, specifically under spec.ipam.podCIDRs . The Cilium agent waits for this allocation during startup and then performs host-local allocation of individual pod addresses from the CIDR assigned to its node.
This division of responsibility explains why C is correct. The agent consumes its assigned range and allocates endpoint addresses locally, but it does not independently choose the cluster-wide per-node PodCIDR. The Operator coordinates those ranges to prevent nodes from receiving overlapping allocations.
Options A and D describe Kubernetes host-scope IPAM rather than Cilium cluster-scope IPAM. In Kubernetes host-scope mode, the Kubernetes controller manager assigns PodCIDRs and exposes them through spec.podCIDR or spec.podCIDRs in the standard Kubernetes Node resource. Cluster-scope mode is specifically useful when Kubernetes is not configured to perform that allocation or when Cilium should control the cluster address pool.
Therefore, the managing component and resource are the Cilium Operator and CiliumNode , respectively.

質問 # 44
What is the default policy enforcement behavior?
正解：C
解説：
Technical explanation
In Cilium's default policy-enforcement mode, an endpoint initially permits ingress and egress traffic.
Enforcement changes independently for each direction when a policy selects that endpoint. If a selecting rule contains an ingress section, the endpoint enters default-deny mode for ingress. If a selecting rule contains an egress section, it enters default-deny mode for egress. Only traffic explicitly permitted by the applicable policy rules remains allowed in the restricted direction.
This per-direction behavior is important. An ingress-only policy does not automatically restrict egress, and an egress-only policy does not automatically restrict ingress. Options A and B reverse the relationship between the rule section and the direction being enforced. Option C incorrectly states that selection places the endpoint into default-allow mode; default allow describes the endpoint's condition before it is selected by an enforcing policy.
Cilium also supports always and never enforcement modes. In always , enforcement applies even to endpoints not selected by policy. In never , policy enforcement is disabled. Policies can additionally use enableDefaultDeny for specialized visibility configurations, but those controls do not change the normal default behavior described in the question.

質問 # 45
Which one of the following statements accurately describes the identity-based network security model used by Cilium?
正解：C
解説：
Technical explanation
Cilium derives an endpoint's security identity from its security-relevant labels rather than from its current IP address. When multiple endpoints possess the same relevant label set, they receive and share the same numeric security identity. This enables policies to follow an application as pods are recreated, rescheduled, or scaled across nodes.
In Kubernetes, the Cilium agent obtains workload metadata through the Kubernetes API and associates the pod's labels with the corresponding Cilium endpoint. Identity allocation converts the relevant label set into a cluster-wide identity. Policy enforcement then matches that identity in the eBPF datapath instead of depending exclusively on short-lived pod addresses.
Option A incorrectly makes the IP address the source of identity and says that identities cannot be shared.
Option B incorrectly identifies annotations as the identity foundation. Annotations may configure behavior, but Cilium's security model is label-based. Option D is also incorrect because operators do not ordinarily assign each pod's numeric security identity manually. Identity allocation and lifecycle management are automatic.

質問 # 46
A user has set up a global service as a Kubernetes user with access to clusters in a Cilium Cluster Mesh. They notice that all traffic is going to remote backend pods. What is a possible explanation?
正解：C
解説：
Technical explanation
If a global Service has no healthy local endpoints matching its selector, every available backend can be remote. Cluster Mesh synchronizes remote service and endpoint information, allowing the local Cilium datapath to load-balance requests to backend pods in connected clusters. The absence of local endpoints therefore provides a direct explanation for the observed behavior.
If the local cluster were not part of the Cluster Mesh, its Cilium agents would not normally receive the remote endpoint state needed to route traffic through the global Service, so B does not explain successful remote-only selection. An affinity value of none is the default behavior and expresses no preference between local and remote endpoints. When both categories exist and are healthy, this permits load balancing across both; it does not require every connection to use remote backends.
Setting service.cilium.io/shared: "false" prevents the local Service's backends from being shared with remote clusters. It does not instruct the local cluster to direct all requests toward remote endpoints.
A separate possible cause, not presented among the choices, would be service.cilium.io/affinity: "remote" .
Among the supplied answers, however, A is the valid explanation.

質問 # 47
Which one of the following best describes the role Cilium provides in Kubernetes?
正解：D
解説：
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.
