NEW QUESTION # 22
Why is the iptables implementation of kube-proxy less scalable than eBPF?
Answer: D
Explanation:
Technical explanation
B expresses the principal scalability distinction intended by the question. In kube-proxy's iptables mode, Kubernetes Services and endpoints are represented by chains of netfilter rules. As the number of Services and backends grows, rule creation, synchronization, and packet traversal can involve increasingly large rule sets.
Matching through those chains is generally described as having linear scaling characteristics.
Cilium's kube-proxy replacement stores service and backend state in eBPF maps. Hash-map lookups allow the datapath to locate service entries without sequentially scanning a rule for every Service, providing effectively constant-time lookup behavior for the relevant map operations. This makes the approach better suited to large and frequently changing Kubernetes environments.
Option A is false because iptables and netfilter also operate within the Linux kernel. Option C is false because kube-proxy's iptables implementation supports IPv6 when the surrounding Kubernetes and host configuration supports it. Option D does not explain kube-proxy's primary scaling limitation and introduces an unrelated SmartNIC/XDP claim.
The constant-time description is a useful architectural simplification; total performance still depends on map sizing, backend selection, connection tracking, and kernel behavior.

NEW QUESTION # 23
Which component is embedded in the Cilium Agent and retrieves eBPF-based visibility from Cilium?
Answer: B
Explanation:
Technical explanation
The Hubble Server is embedded in each Cilium agent and consumes the eBPF-derived visibility data produced on that node. It exposes gRPC services through which clients can retrieve flow events, node and namespace information, server status, and related observability data. Embedding the server in the agent enables high-performance collection with comparatively low overhead.
Hubble Relay has a different role. It is a standalone component that discovers and connects to the Hubble Server instances running across the cluster. Relay aggregates their individual APIs to provide multi-node or cluster-wide visibility to clients such as the Hubble CLI and Hubble UI. It is therefore not the component embedded in the agent.
The Cilium CNI plugin is invoked when Kubernetes creates or removes pods and asks the local agent to configure their networking and datapath. The Cilium Operator performs cluster-wide management duties such as selected IPAM and shared-state operations. Neither component is responsible for exposing eBPF flow visibility.
This server-relay distinction is central to understanding Hubble's distributed architecture: Server provides node-local visibility, while Relay combines multiple servers into a cluster-wide view.

NEW QUESTION # 24
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?
Answer: C
Explanation:
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.

NEW QUESTION # 25
What is NOT a valid description of the sidecar-based model?
Answer: A
Explanation:
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.

NEW QUESTION # 26
Which one of the following best describes the role Cilium provides in Kubernetes?
Answer: B
Explanation:
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.
