質問 # 61
Which component, when available, is able to handle IPAM requests?
正解：A
解説：
Technical explanation
The Cilium Operator handles IP address management responsibilities in IPAM modes that require cluster- wide or cloud-integrated allocation. Current documentation identifies the operator as responsible for IPAM in Azure IPAM, AWS ENI, and cluster-scope mode. Cloud-specific operators populate the appropriate allocation information in CiliumNode resources, after which node-local agents allocate addresses to endpoints from the available ranges.
The phrase "when available" is important because responsibilities vary by IPAM mode. Under Kubernetes host-scope IPAM, Kubernetes allocates each node's PodCIDR, and the Cilium agent consumes that range from the Kubernetes Node object. Nevertheless, among the supplied components, the operator is the component specifically associated with centralized IPAM requests and allocation management.
The Cilium agent implements each node's datapath and endpoint lifecycle but is not the general cluster-wide IPAM answer intended here. Cilium API Server is not the documented allocation component. The misspelled Cilium CNIPIugin refers to the CNI plugin, which requests networking setup when a pod is created but does not replace the operator's IPAM responsibilities.

質問 # 62
In which use case can the Cilium Service Mesh exclusively utilize eBPF without requiring a proxy such as Envoy?
正解：B
解説：
Technical explanation
Cilium can implement Layer 3 and Layer 4 forwarding exclusively through its eBPF datapath. IP, TCP, and UDP traffic can be routed, load-balanced, filtered, and redirected through eBPF programs attached to Linux networking hooks. These operations depend on network-layer addresses, protocols, ports, identities, and connection state; they do not require application-protocol parsing by a userspace proxy.
Application-layer operations are different. Cilium's official Service Mesh architecture uses a proxy such as Envoy to parse HTTP, gRPC, and DNS when Layer 7 policy, observability, or traffic management requires understanding individual requests. The eBPF datapath transparently redirects selected traffic to the node-local proxy and retains identity context, while Envoy performs the protocol-aware operation.
Kafka parsing is also an application-layer activity rather than ordinary Layer 3 or Layer 4 forwarding.
Moreover, current Cilium releases removed the former Envoy Go extension mechanism used for Kafka and generic proxylib rules, further reinforcing that it is not an eBPF-only forwarding case.
Therefore, D accurately identifies the scenario in which the Service Mesh datapath can remain entirely in the kernel without requiring Envoy.

質問 # 63
Which Cilium command should you execute to gather network-related troubleshooting information from your Kubernetes cluster?
正解：D
質問 # 64
Which proxy does Cilium use to enforce HTTP and other Layer 7 (L7) policies specified in network policies for the cluster?
正解：A
解説：
Technical explanation
Cilium uses Envoy as its userspace Layer 7 proxy. When a Cilium policy contains HTTP or another supported application-layer rule, Cilium's eBPF datapath identifies matching traffic and redirects it to a node-local Envoy instance. Envoy evaluates the application-layer attributes-such as HTTP method, path, or headers- against the generated policy configuration and then forwards or rejects the request.
The proxy can operate in embedded mode as a separate process inside the Cilium agent pod or as the independently life-cycled cilium-envoy DaemonSet. Both deployment forms use Cilium's optimized Envoy distribution and custom policy-enforcement filters. Communication between the agent and Envoy uses local UNIX-domain sockets for configuration, access logs, and administrative operations.
HAProxy is a capable general-purpose load balancer, but it is not Cilium's L7 policy proxy. Squid primarily serves forward and caching proxy use cases. linkerd2-proxy belongs to the Linkerd service mesh and is not used by Cilium for network-policy enforcement. Consequently, only D identifies the proxy integrated into Cilium's L7 datapath.

質問 # 65
When using Cilium with the kube-proxy replacement enabled, which underlying technology is effectively replaced with eBPF?
正解：A
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.
