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.

Technical explanation

C is not a valid description. A service-mesh sidecar externalizes networking functions into a proxy container running beside the application; it does not force the instrumentation logic into the application’s source code. In fact, a core service-mesh objective is to provide connectivity, security, traffic management, and observability transparently without requiring application-code changes.

The operational concerns in the other choices are characteristic of sidecar implementations. A proxy must be injected into each workload pod, increasing container count and potentially affecting pod initialization, resource consumption, ordering, and readiness. Adding a sidecar to an existing pod template normally requires the pods to be recreated because Kubernetes cannot dynamically add a new container to an already-running pod.

Traffic interception also directs application traffic through the sidecar proxy and its network namespace paths, adding network-stack traversal and proxy-processing overhead. Cilium’s service-mesh design can instead use node-level Envoy proxies together with eBPF traffic redirection, avoiding one proxy container in every application pod. This preserves transparent application behavior while reducing the per-workload operational burden.
