質問 # 54
Which component, when available, is able to handle IPAM requests?
正解：B
解説：
Technical explanation
The Cilium Operator handles IP address management responsibilities in IPAM modes that require cluster- wide or cloud-integrated allocation. Current documentation identifies the operator as responsible for IPAM in Azure IPAM, AWS ENI, and cluster-scope mode. Cloud-specific operators populate the appropriate allocation information in CiliumNode resources, after which node-local agents allocate addresses to endpoints from the available ranges.
The phrase "when available" is important because responsibilities vary by IPAM mode. Under Kubernetes host-scope IPAM, Kubernetes allocates each node's PodCIDR, and the Cilium agent consumes that range from the Kubernetes Node object. Nevertheless, among the supplied components, the operator is the component specifically associated with centralized IPAM requests and allocation management.
The Cilium agent implements each node's datapath and endpoint lifecycle but is not the general cluster-wide IPAM answer intended here. Cilium API Server is not the documented allocation component. The misspelled Cilium CNIPIugin refers to the CNI plugin, which requests networking setup when a pod is created but does not replace the operator's IPAM responsibilities.

質問 # 55
What is the issue with the following egress gateway manifest specification?
Egress gateway manifest exhibit
正解：B
解説：
Technical explanation
The manifest specifies both interface: net1 and egressIP: 10.3.4.5 in the same egressGateway configuration.
These properties are mutually exclusive. Cilium ignores an Egress Gateway policy containing both, so A correctly identifies the defect.
When interface is supplied, Cilium uses the selected interface and chooses its first suitable IPv4 and IPv6 addresses as the SNAT addresses. When egressIP is supplied, that address must already be assigned to a network device on the chosen gateway node; Cilium determines the corresponding interface through a route lookup. Administrators may also omit both fields, causing Cilium to select the default-route interface and its addresses.
Option B is incorrect because matchLabels can contain multiple label key-value pairs, as the exhibit does with app: blog and component: backend . Option C is false because the egress address need not be publicly routable; private addresses are valid when routing and upstream network design support them. Option D is false because Cilium does not restrict gateway interfaces to names beginning with eth .

質問 # 56
A Kubernetes cluster is not currently running Cilium as a CNI, but the user would like to benefit from Hubbies observability capabilities on your cluster. Which one of the following options is NOT possible?
正解：B
解説：
Technical explanation
Hubble is Cilium's integrated observability layer and consumes flow events produced by Cilium's eBPF datapath and embedded Hubble servers. The Hubble CLI is only a client; downloading its binary does not install a standalone datapath or create flow data on a cluster that lacks Cilium. Option B is therefore the operation that is not possible.
The other approaches represent recognized Cilium deployment or migration models. A direct migration can replace the CNI configuration and recycle workloads or nodes, although a naive cluster-wide transition can disrupt connectivity. CNI chaining allows Cilium to operate with another CNI: the existing plugin continues to provide basic connectivity and IP address management, while Cilium attaches eBPF programs to the created interfaces to provide visibility, policy, and other functions. Cilium also documents migration through dual overlays. In that model, the old and new networks coexist temporarily, nodes are moved in a controlled sequence, and workloads attached to either overlay retain connectivity when the documented addressing and routing requirements are met.
The supplied bank incorrectly marks A. The verified answer is B because Hubble requires Cilium-managed observability data.

質問 # 57
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?
正解：D
解説：
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.

質問 # 58
Why is the iptables implementation of kube-proxy less scalable than eBPF?
正解：B
解説：
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.
