質問 # 20
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 # 21
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 # 22
Which command is used to enable logging at the debug log level of Cilium agents7
正解：D
解説：
Technical explanation
cilium config set debug true follows the supported Cilium CLI configuration syntax and sets the debug configuration key to true . The cilium config set command accepts a key/value pair and, by default, restarts the Cilium pods so that the changed configuration is applied. The Cilium configuration documentation defines debug as the setting that enables full debug mode. This increases agent logging verbosity and causes eBPF programs to emit additional visibility events for diagnostic use.
Options A, B, and D do not match documented Cilium CLI command structures. There is no cilium log level
--set=debug command in the Cilium CLI hierarchy, and neither cilium logging.level=debug nor cilium logging debug is valid configuration syntax. A Helm-managed installation may also enable debugging through the chart value debug.enabled=true , but that does not make any of the alternative commands correct.
Debug mode should be enabled deliberately because it increases log volume and may generate additional datapath visibility information. After troubleshooting, operators should normally restore the previous setting to avoid unnecessary operational overhead.
The supplied answer key incorrectly identifies B. The verified answer is C.

質問 # 23 
Cilium status exhibit
Based on the cilium status output above, what is correct about the Cilium deployment?
For accessibility, the output of the command has been edited.
正解：B
解説：
Technical explanation
The status output reports Operator: OK , followed by Deployment cilium-operator Desired: 1, Ready: 1/1, Available: 1/1 . This establishes that the Cilium Operator is deployed and healthy, making B the intended answer. Cilium uses Kubernetes CustomResourceDefinitions as its default mechanism for storing and propagating cluster state, while the operator performs cluster-wide duties that should be handled once centrally rather than independently on every node.
Option A is contradicted by the exhibit: both hubble-ui and hubble-relay appear as ready deployments and running containers. Option C is incorrect because the resource is explicitly identified as a Deployment ; the cilium agents, by contrast, are shown as a DaemonSet . Option D incorrectly treats the displayed desired replica count as a permanent restriction. A desired count of one describes this installation's current configuration, not a universal maximum.
The exhibit also shows embedded Envoy mode and three healthy Cilium agent instances, but neither detail changes the operator conclusion.

質問 # 24
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.
