53. Frage
Which question does Hubble provide the information to answer?
Antwort: B
Begründung:
Technical explanation
Hubble provides network and security flow observability derived from Cilium's datapath. Its flow records include source and destination workloads, namespaces, identities, ports, protocols, forwarding verdicts, and drop reasons. Hubble can therefore identify services or workloads whose connections were rejected by network policy. The Hubble CLI supports filtering by verdict, such as --verdict DROPPED , and official examples show events labeled Policy denied DROPPED . These capabilities directly answer the question posed in option D.
Option B, which is marked as correct in the supplied bank, is not supported by the stated functionality.
Hubble may expose network-layer or supported application-layer metadata, including DNS and HTTP information when Layer 7 visibility is configured, but it is not a database query profiler and cannot determine which internal SQL statement ran longest merely from ordinary Hubble flows. Similarly, CPU utilization is a workload-resource metric normally obtained through Kubernetes metrics, Prometheus, or another monitoring system. Cilium BGP configuration is examined through Cilium configuration and BGP status commands rather than inferred from Hubble network flows.
The supplied answer key should therefore be corrected from B to D.

54. Frage
You are managing two Kubernetes clusters, labeled as Cluster A and Cluster B, both of which have Cilium installed. You want to mesh Cluster A and Cluster B together The following characteristics define these clusters:
# Both clusters are configured In encapsulation mode.
# The PodCIDR ranges differ: Cluster A uses 192.168.0.0723, while Cluster B uses 192.168.2.0/24.
# There is IP connectivity between the nodes in all clusters using their respective InternallP addresses.
# The network infrastructure between the clusters enables inter-cluster communication.
# Cluster A runs Kubernetes version 1.28, and Cluster B runs Kubernetes version 1.27.
# Cilium versions also differ, with Cluster A using version 1.14 and Cluster B using version 1.13.
# Both clusters share the same cluster name and cluster ID.
# The Cilium certificate authority differs between Cluster A and Cluster B.
Is it possible to create a cluster mesh given the conditions?
Antwort: C
Begründung:
Technical explanation
A Cluster Mesh can be created after assigning each cluster a unique name and numeric cluster ID. Cilium uses the cluster ID when constructing Cluster Mesh security identities, so duplicate values cannot safely identify endpoints from different clusters. The name must likewise be unique. These values can be changed after installation, although all existing workloads must then be restarted so their security identities are regenerated.
The other listed conditions are compatible. Both clusters use the same encapsulation datapath mode, their PodCIDRs are intended to be non-overlapping, and the nodes possess the required inter-cluster connectivity.
Different Kubernetes patch or minor versions do not inherently prevent Cluster Mesh. Cilium versions may differ by one minor release, so versions 1.14 and 1.13 satisfy the documented compatibility rule.
Different certificate authorities are not an irreversible blocker under current documentation. Every cluster must trust certificates presented by the others. Operators may use a shared root CA or configure a CA bundle containing all trusted CA certificates. Consequently, B is too absolute. C is also false because changing the cluster identity is possible, subject to workload restarts. D is unnecessary because a one-minor Cilium difference is supported.
The source's option A is truncated, but its intended corrective action is technically accurate.

55. Frage
In which use case can the Cilium Service Mesh exclusively utilize eBPF without requiring a proxy such as Envoy?
Antwort: B
Begründung:
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.

56. Frage
You need to expose an application over HTTPS on your Cilium-managed Kubernetes cluster The security team has specifically asked for traffic to be encrypted all the way from the external clients to the Service.
Which option should you use?
Antwort: D
Begründung:
Technical explanation
The requirement is that traffic remain encrypted all the way from the external client to the backend Service .
Therefore, TLS must not terminate at the Cilium Gateway/Envoy proxy .
With TLS Passthrough , Cilium forwards the encrypted TLS stream to the backend without decrypting the application traffic. Envoy can inspect the TLS ClientHello/SNI sufficiently to select the appropriate backend, but the TLS session itself continues to the Service. Cilium specifically supports TLS passthrough with the Gateway API TLSRoute resource .
By contrast, TLS Terminate + HTTPRoute decrypts the connection at the Gateway. Although a separate encrypted connection to the backend can be configured in some architectures, that is not the same as preserving the original end-to-end TLS session requested here. Cilium's HTTPS Gateway examples use TLS termination when the Gateway itself handles the certificate.

57. Frage
Which component manages the allocation of per-node PodCIDRs in the cluster-scope IPAM (IP address management) mode?
Antwort: D
Begründung:
Technical explanation
In cluster-scope IPAM, the Cilium Operator allocates a PodCIDR to each node from the configured cluster- wide address pool. It records those allocations in each node's CiliumNode custom resource, specifically under spec.ipam.podCIDRs . The Cilium agent waits for this allocation during startup and then performs host-local allocation of individual pod addresses from the CIDR assigned to its node.
This division of responsibility explains why C is correct. The agent consumes its assigned range and allocates endpoint addresses locally, but it does not independently choose the cluster-wide per-node PodCIDR. The Operator coordinates those ranges to prevent nodes from receiving overlapping allocations.
Options A and D describe Kubernetes host-scope IPAM rather than Cilium cluster-scope IPAM. In Kubernetes host-scope mode, the Kubernetes controller manager assigns PodCIDRs and exposes them through spec.podCIDR or spec.podCIDRs in the standard Kubernetes Node resource. Cluster-scope mode is specifically useful when Kubernetes is not configured to perform that allocation or when Cilium should control the cluster address pool.
Therefore, the managing component and resource are the Cilium Operator and CiliumNode , respectively.
