Linux Foundation Cilium Certified AssociateCCA 認定 Cilium-Associate 試験問題 (Q43-Q48):

質問 # 43
Which one of the following best describes the role Cilium provides in Kubernetes?

正解:C

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.

質問 # 44
This an Ingress configuration. What is the equivalent Gateway API configuration?

Question 19 source Ingress
A)

Question 19 option A
B)

Question 19 option B
C)

Question 19 option C
D)

Question 19 option D

正解:D

解説:
Technical explanation
Option B correctly represents the Ingress as a Gateway and an attached HTTPRoute . The Gateway is named cilium , uses gatewayClassName: cilium , and exposes an HTTP listener on port 80. The HTTPRoute uses parentRefs with the same Gateway name, cilium , so the route attaches to the declared listener. Its two rules preserve the original routing behavior: /details with PathPrefix targets the details Service on port 9080, while / with PathPrefix targets productpage on port 9080.
Option A declares a Gateway named cilium but attaches its route to nginx-gateway . Because the parent reference does not identify the displayed Gateway, it is not equivalent. Options C and D use kind: Route ; the correct resource kind for HTTP path routing is HTTPRoute . They also contain malformed or altered backend and matching fields. Option D changes the details backend name, while option C contains incorrect route structure and path content.
Cilium's official migration example uses the same conversion pattern: the Ingress class becomes the Gateway' s class, paths move into HTTPRoute.rules , and the route identifies its Gateway through parentRefs .
The supplied key incorrectly identifies A. The verified answer is B.

質問 # 45
The application team would like to observe egress traffic with application level information for workloads running in a Cilium based Kubernetes Cluster Which features would offer this without the need for additional tooling?

正解:A

解説:
Technical explanation
Hubble UI and Hubble CLI are Cilium's integrated interfaces for examining workload network flows. Hubble records source and destination identities, namespaces, workloads, addresses, ports, forwarding verdicts, and drop reasons. When Layer 7 visibility is configured, its flow output can also contain application-level information such as HTTP methods, URLs, response codes, latency, and DNS queries. Filters can narrow the results by source workload, namespace, destination, protocol, port, or verdict, making Hubble appropriate for investigating egress behavior.
Hubble CLI provides detailed event-oriented inspection, while Hubble UI presents flows and service dependencies graphically. Hubble Relay aggregates the per-node Hubble APIs so these clients can obtain cluster-wide visibility.
Load balancing directs traffic but is not an observability interface. Kubernetes NetworkPolicy expresses permitted communications but does not by itself display application-level flow records. Fluentd and Grafana are external logging and visualization components and would violate the requirement to avoid additional tooling.
Layer 7 information requires supported traffic to be redirected through Cilium's L7 proxy. Hubble then exposes the resulting application-layer flow events through the built-in CLI or UI, making D the complete answer.

質問 # 46
Please review the output of cilium status below and answer the question that follows. Please note, the output has been modified for accessibility purposes.

Question 2 cilium status exhibit
Assume the cluster is healthy. What is correct about the ci 1 ium status command output above?

正解:A

解説:
Technical explanation
The status output shows Envoy DaemonSet: disabled (using embedded mode) . In embedded mode, Cilium starts Envoy as a separate process inside the Cilium agent pod when a feature requiring Layer 7 processing- such as an L7 network policy, protocol visibility, Ingress, or Gateway API-is used. This is precisely the behavior described in option B.
The remaining choices contradict the exhibit. The Cilium DaemonSet has a desired count of three, which ordinarily indicates three schedulable nodes running Cilium, not four. Hubble Relay: OK means the aggregation component is healthy. Hubble Relay connects to the Hubble instances associated with Cilium agents and presents a multi-node API to clients such as Hubble CLI and Hubble UI. Finally, ClusterMesh:
disabled rules out the claim that the installation is currently configured for Cilium Cluster Mesh service discovery and cross-cluster load balancing.
Cilium can alternatively run Envoy through the independently life-cycled cilium-envoy DaemonSet. That is not the deployment displayed here because the DaemonSet is explicitly disabled and embedded mode is reported.

質問 # 47
In which use case can the Cilium Service Mesh exclusively utilize eBPF without requiring a proxy such as Envoy?

正解:D

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.
