                                        質問 # 45
                                        Which of these observability features is NOT supported by Hubble?

                                        • A. Hubble Is able to filter flows based on a given Kubernetes node name.
                                        • B. Hubble is able to filter traffic based on the network policy verdict.
                                        • C. Hubble is able to observe by HTTP Status code (like "404" or "200").
                                        • D. Hubble Is able to provide Layer 7 visibility In eBPF, without the need for a proxy.

                                        正解:D

                                        解説:
                                        Technical explanation
                                        Hubble does not obtain Layer 7 protocol visibility exclusively through eBPF without a proxy. By default, Cilium's datapath exposes Layer 3 and Layer 4 flow information. To produce supported application-layer events, traffic is selected through an L7 Cilium policy and redirected to the node-local Envoy proxy. Envoy parses the application protocol and forwards access-log information that Cilium and Hubble expose as Layer
                                        7 flow events.
                                        The other capabilities are supported. Hubble flow records contain the observing node, and the CLI provides node-based filtering. HTTP-aware flows can contain response status codes, enabling inspection or filtering for results such as 200 and 404. Hubble also records forwarding verdicts and drop reasons. Operators can filter for DROPPED traffic and distinguish policy-denied connections from forwarded traffic and other failure conditions.
                                        This separation is fundamental to Cilium's architecture: eBPF provides efficient kernel-level forwarding, security enforcement, and L3/L4 observability, while Envoy supplies protocol parsing when request-level context is required. The integration remains transparent to applications, but the proxy is still present in the traffic path for Layer 7 visibility.
                                        Therefore, B describes the unsupported mechanism and is the correct answer.

                                        質問 # 46
                                        When using Cilium with the kube-proxy replacement enabled, which underlying technology is effectively replaced with eBPF?

                                        • A. Routing
                                        • B. BGP
                                        • C. firewalld
                                        • D. Iptables/IPVS

                                        正解:D

                                        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.

                                        We observed Hubble output:

                                        Question 7 Hubble flow exhibit
                                        Explain what may have happened:

                                        • A. On test pod (default namespace), someone launched commands: curl 16.244.0.191 #Output: Succeeded curl ie.244.0.191:8080 #Output: Failed
                                        • B. On test2 pod (default namespace), someone launched commands:
                                          curl 16.244.0.143 #Output: Failed curl 10.244.0.143:8080 #Output: Succeeded
                                        • C. On test pod (default namespace), someone launched commands:
                                          curl 19.244.0.191 #Output: Failed
                                          curl 16.244.0.191:8680 #Output: Succeeded
                                        • D. On test2 pod (default namespace), someone launched commands:
                                          curl 10.244.0.143 #Output: Succeeded curl 10.244.0.143:8080 #Output: Failed

                                        正解:A

                                        解説:
                                        Technical explanation
                                        The exhibit records connections originating from default/test and directed to default/test2 , eliminating B and C because those choices reverse the initiating workload. For destination port 80, the flow shows the TCP three-way handshake-SYN, SYN-ACK, and ACK-followed by bidirectional packets with ACK/PSH flags and an orderly FIN exchange. This is the pattern of a successfully established request and response, so the first curl operation succeeded.
                                        The later connection targets port 8080. Hubble records a SYN from test followed by an ACK, RST response from test2 . A reset returned immediately after the connection attempt indicates that the destination rejected or could not accept the connection, commonly because no process was listening on that port. It is not shown as a policy drop; both entries carry the FORWARDED verdict. Thus the network delivered the packets, but the TCP connection itself failed.
                                        Option D is the only choice matching a successful request from test to port 80 and a failed request from test to port 8080. Its displayed IP strings contain source-document transcription defects, but its workload direction, ports, and outcomes match the exhibit.

                                        質問 # 48
                                        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?

                                        • A. NetworkPolicy
                                        • B. CiliumNetworkPolicy
                                        • C. CiliumClusterWideNetworkPolicy
                                        • D. CiliumGlobalPolicy

                                        正解:C

                                        解説:
                                        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.

                                        Which one of the following commands will correctly display show the Cilium configuration?

                                        • A. cilium config view
                                        • B. cilium show run
                                        • C. cilium show config
                                        • D. kubectl describe ciliumconfig.ciliu # .io

                                        正解:A

                                        解説:
                                        Technical explanation
                                        cilium config view is the Cilium CLI command used to display the current Cilium configuration. It reads the configuration associated with the selected Kubernetes context, Cilium namespace, and Helm release. The command belongs to the cilium config command group, which manages installation configuration.
                                        Option B reverses the expected command structure and does not correspond to a documented Cilium CLI operation. Option D resembles command syntax used on traditional network appliances but is not part of the Cilium CLI. Option C is both textually corrupted and conceptually inaccurate: Cilium configuration is not generally exposed through a cluster-wide resource named ciliumconfig.cilium.io . Runtime settings are commonly represented through the Cilium ConfigMap and Helm release values, while specialized resources such as CiliumNodeConfig apply targeted per-node configuration.
                                        The wording "display show" is a source-bank editing defect but does not affect the answer. Administrators should also distinguish the external cilium management CLI from cilium-dbg , which runs with or communicates with the node-local Cilium agent and provides detailed datapath and agent diagnostics.
