질문 # 61
Which question does Hubble provide the information to answer?
정답：B
설명：
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.

We observed Hubble output:
Question 7 Hubble flow exhibit
Explain what may have happened:
정답：A
설명：
Technical explanation
The exhibit records connections originating from default/test and directed to default/test2 , eliminating B and C because those choices reverse the initiating workload. For destination port 80, the flow shows the TCP three-way handshake-SYN, SYN-ACK, and ACK-followed by bidirectional packets with ACK/PSH flags and an orderly FIN exchange. This is the pattern of a successfully established request and response, so the first curl operation succeeded.
The later connection targets port 8080. Hubble records a SYN from test followed by an ACK, RST response from test2 . A reset returned immediately after the connection attempt indicates that the destination rejected or could not accept the connection, commonly because no process was listening on that port. It is not shown as a policy drop; both entries carry the FORWARDED verdict. Thus the network delivered the packets, but the TCP connection itself failed.
Option D is the only choice matching a successful request from test to port 80 and a failed request from test to port 8080. Its displayed IP strings contain source-document transcription defects, but its workload direction, ports, and outcomes match the exhibit.

질문 # 63
Which component, when available, is able to handle IPAM requests?
정답：D
설명：
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.

질문 # 64
What is a correct statement related to BIG TCP, an eBPF-based feature in Cilium?
정답：B
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 # 65
What is true about WireGuard encryption on Cilium?
정답：C
설명：
Technical explanation
B is the best answer, with two qualifications. First, "pop-to-pod" is evidently a source typo for "pod-to-pod." Second, default WireGuard mode encrypts traffic between Cilium-managed pods on different nodes; node-to- node, pod-to-node, and node-to-pod coverage requires enabling the additional encryption.
nodeEncryption=true mode.
Cilium creates WireGuard peers per node, not per pod. Each Cilium agent generates a node key pair, advertises the public key through its CiliumNode resource, and forms secure tunnels with other known nodes.
This makes D incorrect. Same-node packets do not traverse a WireGuard tunnel because encryption cannot protect them from an observer already able to inspect raw traffic on that host, so A reverses the documented behavior.
C also reverses the encapsulation sequence. In tunnel-routing mode, pod traffic is first encapsulated for the VXLAN or Geneve overlay and is then encapsulated by WireGuard. The result is double encapsulation, with WireGuard protecting the overlay packet while it crosses the network between nodes.
Thus, B describes WireGuard's supported traffic coverage most closely, but exam candidates should remember the separate node-encryption configuration requirement.
