質問 # 10
Which question does Hubble provide the information to answer?
正解：A
解説：
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:
正解：A
解説：
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.

質問 # 12
What is true about WireGuard encryption on Cilium?
正解：B
解説：
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.

質問 # 13
What does this Egress Gateway policy achieve?
Cilium Egress Gateway policy exhibit
正解：B
解説：
Cilium's official documentation confirms that a CiliumEgressGatewayPolicy selects traffic originating from matching pods , routes traffic destined for the configured destinationCIDRs through the selected egress gateway node, and SNATs that traffic using the configured egressIP.
質問 # 14
What is correct about the Kubernetes Host Scope IP Address Management (IPAM) mode?
正解：D
解説：
Technical explanation
Kubernetes host-scope IPAM can be used with both Cilium tunnel routing and native direct routing. The IPAM mechanism determines how each node receives and locally allocates pod addresses; it does not inherently require a particular packet-forwarding model. The current IPAM feature matrix explicitly marks both tunnel routing and direct routing as supported for Kubernetes host-scope mode.
In this mode, Kubernetes allocates a PodCIDR to each node and publishes it through the standard v1.Node resource, normally in spec.podCIDR or spec.podCIDRs . The Cilium agent waits for the relevant range and allocates individual pod addresses from that node-specific CIDR. The correct configuration is ipam:
kubernetes or the Helm equivalent ipam.mode=kubernetes , not ipam: crd ; therefore, C is false.
The documented feature matrix does not provide multiple CIDRs per cluster or multiple CIDRs per node for this mode, eliminating A and B. Multi-pool IPAM is the Cilium mode designed for allocating per-node CIDRs from multiple configurable pools.
Because Kubernetes host-scope IPAM supports either overlay tunneling or direct routing while the other statements contradict its capabilities or configuration, D is correct.
