질문 # 42
Which statement about Cilium's identity-based security model is correct?
정답：D
설명：
Technical explanation
Cilium derives a workload's security identity from its security-relevant labels. Network policies then refer to workload characteristics such as application, role, environment, namespace, or service account rather than depending exclusively on transient pod IP addresses. The identity is associated with traffic in the Cilium datapath and validated when policy is enforced. This makes B the accurate description.
The identity is not limited to a single pod. Endpoints that have the same set of identity-relevant labels can share the same numeric security identity, including endpoints located on different cluster nodes. This reduces policy-map growth and allows policy to scale with logical application groups rather than with the number of pod addresses. Namespace information is normally among the labels used to derive identity, but that does not make an identity inherently "tied to a single namespace" as option A states.
Options C and D invert Cilium's design. IP addresses remain necessary for packet delivery, but they are not the primary security identifier for Cilium-managed workloads. Pods can be recreated and assigned new addresses while retaining the same relevant labels and therefore the same security intent. Decoupling identity from addressing is precisely what improves scalability and operational stability.

질문 # 43
Which statement is true about Mutual Authentication with Cilium?
정답：A
설명：
Technical explanation
SPIRE supplies workload identities as SPIFFE Verifiable Identity Documents, including X.509 key material used for mutual authentication. SPIFFE's identity model supports automatic issuance, rotation, and revocation, allowing short-lived certificates to be renewed without manually distributing static credentials.
This makes D the correct statement.
Option A reverses the documented default. Cilium's default SPIRE installation requires persistent-volume support. In-memory storage can be selected for laboratory environments by disabling server data storage, but that setting causes SPIRE data to be recreated if the server pod restarts. Option B also reverses the relationship between the projects: SPIFFE defines the identity standards and APIs, while SPIRE is a production-ready implementation of SPIFFE. Cilium's mutual-authentication integration has been validated with SPIRE.
Option C overstates the operational requirement. A SPIRE server is involved, but Cilium's Helm chart can deploy and configure the supported SPIRE server and per-node agents. Administrators may provide their own deployment, yet a completely manual installation is not mandatory.
Current documentation classifies this mutual-authentication implementation as beta and notes limitations, including incompatibility with Cluster Mesh trust domains. Those maturity constraints do not change the certificate-management behavior described in D.

질문 # 44
In which use case can the Cilium Service Mesh exclusively utilize eBPF without requiring a proxy such as Envoy?
정답：A
설명：
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.

질문 # 45
What is a correct statement related to BIG TCP, an eBPF-based feature in Cilium?
정답：D
설명：
Technical explanation
BIG TCP permits the Linux networking stack to process packets larger than the traditional approximately 64- KiB limit represented by the IP length field while the packets remain inside the host. IPv6 BIG TCP uses a temporary Hop-by-Hop header carrying the larger internal length, while IPv4 BIG TCP sets tot_len to zero and uses the socket buffer length internally. Before transmission, packets are segmented into sizes suitable for the physical network. C therefore identifies the problem BIG TCP addresses.
Option A is false because Cilium's documentation explicitly states that BIG TCP does not require network- interface MTU changes. The larger objects exist inside the software networking stack and are segmented before appearing on the wire.
Option B reverses the intended performance effect. Larger internal GSO and GRO packets reduce repeated stack traversal, lowering CPU utilization and generally improving throughput and latency. Option D is also false: Generic Segmentation Offload and Generic Receive Offload are fundamental to BIG TCP's operation.
Cilium increases their maximum sizes when BIG TCP is enabled. The source mentions TSO, but the documented mechanism is principally described through GSO and GRO.

질문 # 46
Which component manages the allocation of per-node PodCIDRs in the cluster-scope IPAM (IP address management) mode?
정답：D
설명：
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.
