                                        質問 # 21
                                        Which of these observability features is NOT supported by Hubble?

                                        正解:A

                                        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 # 22
                                        A Kubernetes cluster is not currently running Cilium as a CNI, but the user would like to benefit from Hubbies observability capabilities on your cluster. Which one of the following options is NOT possible?

                                        正解:B

                                        解説:
                                        Technical explanation
                                        Hubble is Cilium's integrated observability layer and consumes flow events produced by Cilium's eBPF datapath and embedded Hubble servers. The Hubble CLI is only a client; downloading its binary does not install a standalone datapath or create flow data on a cluster that lacks Cilium. Option B is therefore the operation that is not possible.
                                        The other approaches represent recognized Cilium deployment or migration models. A direct migration can replace the CNI configuration and recycle workloads or nodes, although a naive cluster-wide transition can disrupt connectivity. CNI chaining allows Cilium to operate with another CNI: the existing plugin continues to provide basic connectivity and IP address management, while Cilium attaches eBPF programs to the created interfaces to provide visibility, policy, and other functions. Cilium also documents migration through dual overlays. In that model, the old and new networks coexist temporarily, nodes are moved in a controlled sequence, and workloads attached to either overlay retain connectivity when the documented addressing and routing requirements are met.
                                        The supplied bank incorrectly marks A. The verified answer is B because Hubble requires Cilium-managed observability data.

                                        質問 # 23
                                        You are creating a Cilium network policy for pods with the label app: frontend . The policy should allow all pods with that label to communicate with destinations inside 192.168.e.e/24 and using TCP on port 8888.
                                        For example:
                                        # Traffic to 192.168.9.23:8888 should be allowed
                                        # Traffic to 192.168.10.5:8888 should be denied.
                                        # Traffic to 192.168.9.12:5606 should be denied.
                                        Which of the following policies is correct?
                                        A)

                                        Option A
                                        B)

                                        Option B
                                        C)

                                        Option C
                                        D)

                                        Option D

                                        正解:C

                                        解説:
                                        Technical explanation
                                        Option C has the correct Cilium policy structure. It selects pods labeled app: frontend , creates an egress rule with a valid CIDR entry, and combines that destination constraint with toPorts , port 8888 , and protocol TCP
                                        . Because the CIDR and port restriction are in the same egress rule, traffic must meet both conditions.
                                        Option A uses an unsupported address-range structure with from and to fields rather than CIDR notation.
                                        Option B initially resembles the correct form but contains an additional malformed ports item at the egress- rule level. Option D uses unsupported action: allow and action: deny fields inside toPorts ; Cilium allow and deny behavior is expressed through policy sections such as egress and egressDeny , not per-port action properties.
                                        The item is nevertheless defective. The prose and examples indicate 192.168.9.0/24 , while all displayed CIDR-based options specify 192.168.0.0/24 ; the source text itself shows the corrupted 192.168.e.e/24 . If
                                        192.168.9.0/24 is authoritative, none of the exhibits permits the stated example. The supplied key B is structurally incorrect under the displayed manifests.

                                        When considering changing an existing cluster's IPAM (IP address management) mode, what is the safest path?

                                        正解:A

                                        解説:
                                        Technical explanation
                                        The official IPAM documentation expressly states that the safest way to change IPAM mode is to install a fresh Kubernetes cluster using the required new IPAM configuration. A live cluster already contains allocated workload addresses, node routing state, Cilium endpoint state, service state, and potentially cloud-provider resources that depend on the active allocator. Replacing the allocator in place can invalidate these assumptions and cause persistent connectivity disruption rather than merely a short agent restart.
                                        Updating a Kubernetes Node object does not generally convert Cilium's IPAM mode. The responsible resource and allocation behavior depend on the selected mode: Kubernetes host-scope IPAM, cluster-pool IPAM, multi-pool IPAM, CRD-backed modes, and cloud-specific allocators manage address information differently. Restarting agents after changing a configuration value likewise does not constitute a safe migration plan, because existing endpoints and routes may retain state created under the former allocator.
                                        Cilium advises against changing the IPAM mode of an existing cluster unless a specifically documented migration procedure applies. The currently documented exception is migration from cluster-pool IPAM to multi-pool IPAM. As the question provides no such constrained scenario, D is the unambiguously safest answer.

                                        What are the differences between Ingress and Gateway API?

                                        正解:A

                                        解説:
                                        Technical explanation
                                        Ingress provides a comparatively simple API for exposing HTTP and HTTPS applications through host- and path-based routing. Gateway API is a broader, extensible family of resources that separates infrastructure configuration from application routing. Resources such as GatewayClass , Gateway , HTTPRoute , GRPCRoute , TLSRoute , TCPRoute , and UDPRoute model listeners, routes, protocols, ownership, and attachment relationships explicitly.
                                        Gateway API was designed around operational roles. An infrastructure provider can manage the GatewayClass , a cluster operator can provision a Gateway , and an application team can own a route attached to that Gateway. This offers clearer delegation than the single Ingress resource and supports protocols and traffic-management functions beyond the original Ingress model.
                                        The two APIs are not simply different names for identical functionality, so A is false. Option C is also inaccurate because Cilium's implementations of both Ingress and Gateway API integrate with its eBPF datapath and Envoy; Ingress is not inherently an iptables-only implementation. Option D incorrectly limits Gateway API to internal routing. It can expose internet-facing applications through generated LoadBalancer or NodePort Services or through host-network listeners.
