質問 # 54
You are tasked to install Cilium and enable transparent encryption in a cluster in which the following conditions applies:
# Internal cluster traffic is IPv6-only
# The current cluster is running on 5001 nodes
# The cluster is planned to connect to another cluster which has 5001 nodes through Cluster Mesh What are your recommendations regarding transparent encryption?
正解:B
解説:
Technical explanation
A is a supported recommendation: Cilium's WireGuard implementation provides transparent encryption between Cilium-managed endpoints, works with Cluster Mesh, and distributes node public keys to remote clusters through clustermesh-apiserver . All participating clusters must enable WireGuard, and inter-cluster firewalls must permit UDP port 51871. IPv6-only pod traffic does not inherently disqualify WireGuard.
However, this question is no longer uniquely answerable from current Cilium documentation. Current IPsec documentation supports IPv6 pod-to-pod connectivity and sets its cluster or Cluster Mesh limit at more than
65,535 nodes. The described mesh contains 10,002 nodes, so option B is also technically supportable under the stated facts. The older distinction apparently assumed by the supplied key is no longer sufficient to exclude IPsec.
Options C and D are definitively false. Ten thousand and two nodes remain below the documented IPsec ceiling, and transparent encryption is not restricted to IPv4. WireGuard may still be selected for its automatic per-node key-pair distribution and simpler Cluster Mesh integration, but workload performance, kernel support, firewall rules, key-management requirements, and operational testing should inform a production recommendation.

What is true about Layer 7 protocol visibility in Cilium?
正解:D
解説:
Technical explanation
Layer 7 protocol visibility redirects traffic matching the relevant L7 rules to Cilium's node-local proxy, which is Envoy. Envoy parses supported application protocols and supplies the resulting request or response metadata to Cilium's observability pipeline. Therefore, C correctly identifies the architectural consequence of enabling this visibility.
The feature requires L7 proxy support and an appropriate CiliumNetworkPolicy containing Layer 7 rules. A standard Kubernetes NetworkPolicy is limited to Layer 3 and Layer 4 concepts and cannot express Cilium's HTTP, DNS, or generic application-protocol rules, so B is incorrect.
A is also incorrect. DNS policy and visibility are commonly applied to pod egress queries, and Cilium's model is not restricted to ingress-only DNS visibility. D overstates protocol coverage. Cilium supports defined L7 parsers and policy types-most prominently HTTP, DNS, Kafka, and supported generic Envoy- based protocols-but it does not promise arbitrary visibility for every application protocol. SSH, Telnet, and FTP cannot simply be assumed to receive native semantic parsing.
An operational caveat is that L7 visibility rules also affect policy enforcement: they are not merely passive packet logging instructions.

質問 # 56
Which statement about Cilium's identity-based security model is correct?
正解:A
解説:
Technical explanation
Cilium derives a workload's security identity from its security-relevant labels. Network policies then refer to workload characteristics such as application, role, environment, namespace, or service account rather than depending exclusively on transient pod IP addresses. The identity is associated with traffic in the Cilium datapath and validated when policy is enforced. This makes B the accurate description.
The identity is not limited to a single pod. Endpoints that have the same set of identity-relevant labels can share the same numeric security identity, including endpoints located on different cluster nodes. This reduces policy-map growth and allows policy to scale with logical application groups rather than with the number of pod addresses. Namespace information is normally among the labels used to derive identity, but that does not make an identity inherently "tied to a single namespace" as option A states.
Options C and D invert Cilium's design. IP addresses remain necessary for packet delivery, but they are not the primary security identifier for Cilium-managed workloads. Pods can be recreated and assigned new addresses while retaining the same relevant labels and therefore the same security intent. Decoupling identity from addressing is precisely what improves scalability and operational stability.

質問 # 57
What is correct about the Kubernetes Host Scope IP Address Management (IPAM) mode?
正解:C
解説:
Technical explanation
Kubernetes host-scope IPAM can be used with both Cilium tunnel routing and native direct routing. The IPAM mechanism determines how each node receives and locally allocates pod addresses; it does not inherently require a particular packet-forwarding model. The current IPAM feature matrix explicitly marks both tunnel routing and direct routing as supported for Kubernetes host-scope mode.
In this mode, Kubernetes allocates a PodCIDR to each node and publishes it through the standard v1.Node resource, normally in spec.podCIDR or spec.podCIDRs . The Cilium agent waits for the relevant range and allocates individual pod addresses from that node-specific CIDR. The correct configuration is ipam:
kubernetes or the Helm equivalent ipam.mode=kubernetes , not ipam: crd ; therefore, C is false.
The documented feature matrix does not provide multiple CIDRs per cluster or multiple CIDRs per node for this mode, eliminating A and B. Multi-pool IPAM is the Cilium mode designed for allocating per-node CIDRs from multiple configurable pools.
Because Kubernetes host-scope IPAM supports either overlay tunneling or direct routing while the other statements contradict its capabilities or configuration, D is correct.

質問 # 58
When using Cilium with the kube-proxy replacement enabled, which underlying technology is effectively replaced with eBPF?
正解:B
解説:
Technical explanation
Kubernetes kube-proxy conventionally implements Service translation and load balancing through either iptables or IPVS. With Cilium's kube-proxy replacement enabled, eBPF programs and maps perform Kubernetes Service handling directly in the kernel, including ClusterIP, NodePort, LoadBalancer, ExternalIP, and related service translation functions. C is therefore correct.
The replacement can operate at socket hooks and packet-processing hooks. Service and backend information is stored in eBPF maps, allowing the datapath to select backends and perform address translation without traversing the kube-proxy-generated iptables or IPVS rules normally used for Kubernetes Services.
BGP is not replaced. Cilium's BGP Control Plane is a separate feature used to advertise routes and service addresses to external routers. Routing itself is also not eliminated; Cilium can implement and accelerate routing decisions with eBPF, but packets still require a valid forwarding model. firewalld is a host firewall- management service and is not the underlying Kubernetes Service implementation replaced by kube-proxy replacement.
Relevant installations must satisfy the kernel and device requirements for Cilium's eBPF service load- balancer functionality.
