NEW QUESTION # 27
What is the correct statement about the masquerading feature?
Answer: A
Explanation:
Technical explanation
Masquerading performs source network address translation for qualifying traffic that leaves the cluster.
Because pod addresses are often private and not routable by the external network, Cilium replaces the pod's source address with an address belonging to the egress node. Return traffic can then reach that node, which reverses the translation and delivers the response to the originating pod. B correctly summarizes this behavior.
Masquerading is a form of SNAT, not DNAT. DNAT modifies the destination address, commonly to direct incoming traffic toward another endpoint, so C is incorrect.
Cilium documents its eBPF-based masquerading implementation as the more efficient implementation. The iptables version is the legacy alternative, making A false. Conversely, eBPF masquerading depends on appropriate kernel eBPF capabilities and Cilium's BPF NodePort functionality. It cannot be assumed to work on every kernel version, so D is false. The legacy iptables implementation is the mode documented as broadly working across kernel versions.
Cilium can exclude natively routable CIDRs from masquerading, and administrators may configure separate IPv4 and IPv6 masquerading behavior.

NEW QUESTION # 28
In which use case can the Cilium Service Mesh exclusively utilize eBPF without requiring a proxy such as Envoy?
Answer: B
Explanation:
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.

NEW QUESTION # 29
Which encapsulation protocols are supported when configuring Cilium in tunnel mode?
Answer: A
Explanation:
Technical explanation
Cilium tunnel mode supports VXLAN and Geneve encapsulation. In this routing model, Cilium nodes form an overlay mesh, and traffic exchanged between nodes is carried inside UDP-encapsulated packets. VXLAN is the default tunnel protocol and normally uses UDP port 8472. Geneve is the alternative and normally uses UDP port 6081. Operators select the protocol through the tunnel-protocol configuration setting, whose documented values are vxlan and geneve .
Encapsulation reduces the requirements placed on the underlying network. The underlay only needs to provide IP connectivity between the Kubernetes nodes and permit the selected UDP tunnel port. It does not need to learn or route individual PodCIDRs. Cilium also uses the tunnel metadata to carry information such as the source security identity, avoiding an additional identity lookup on the receiving node.
MPLS, OTV, STT, and EVPN are not supported values for Cilium's tunnel-protocol setting. EVPN may be used in broader data-center network designs, and MPLS is a carrier-routing technology, but neither is a Cilium overlay encapsulation choice. Therefore, B is the only supported pair.

NEW QUESTION # 30
Which one of the following best describes the role Cilium provides in Kubernetes?
Answer: C
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.

NEW QUESTION # 31
Which one of the following commands will correctly display show the Cilium configuration?
Answer: C
Explanation:
Technical explanation
cilium config view is the Cilium CLI command used to display the current Cilium configuration. It reads the configuration associated with the selected Kubernetes context, Cilium namespace, and Helm release. The command belongs to the cilium config command group, which manages installation configuration.
Option B reverses the expected command structure and does not correspond to a documented Cilium CLI operation. Option D resembles command syntax used on traditional network appliances but is not part of the Cilium CLI. Option C is both textually corrupted and conceptually inaccurate: Cilium configuration is not generally exposed through a cluster-wide resource named ciliumconfig.cilium.io . Runtime settings are commonly represented through the Cilium ConfigMap and Helm release values, while specialized resources such as CiliumNodeConfig apply targeted per-node configuration.
The wording "display show" is a source-bank editing defect but does not affect the answer. Administrators should also distinguish the external cilium management CLI from cilium-dbg , which runs with or communicates with the node-local Cilium agent and provides detailed datapath and agent diagnostics.
