질문 # 50
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?
정답：B
설명：
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.

질문 # 51
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?
정답：B
설명：
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.

Which Cilium command should you execute to gather network-related troubleshooting information from your Kubernetes cluster?
정답：A
질문 # 53
We observed Hubble output:
Question 7 Hubble flow exhibit
Explain what may have happened:
정답：D
설명：
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.

질문 # 54
As a Kubernetes user, you have deployed the following Cilium Network Policy:
Cilium Layer 7 network policy exhibit
The network policy is not having any effect. What Is the Issue?
정답：C
설명：
Technical explanation
The policy attaches an HTTP Layer 7 rule to port 80 but omits protocol: TCP from the associated ports entry.
HTTP policy is layered on a Layer 4 TCP rule, and the documented Cilium form explicitly identifies TCP before specifying the HTTP method and path. D therefore identifies the configuration defect intended by the question.
The cross-namespace source selection is valid. The policy resides in namespace back and selects backend pods there. Its fromEndpoints selector explicitly includes k8s:io.kubernetes.pod.namespace: blog , allowing it to select matching app-frontend endpoints in that other namespace. Option A is consequently not an error.
The k8s: source prefix in k8s:app.kubernetes.io/name is also valid Cilium label syntax and identifies the Kubernetes label source, making B false. Port 80 may be used in a Cilium policy; the privileged-port restriction concerns which processes may bind low-numbered ports under operating-system permissions, not whether a network policy can reference them.
The corrected port entry should contain port: "80" together with protocol: TCP .
