質問 # 55
When considering changing an existing cluster's IPAM (IP address management) mode, what is the safest path?
正解：C
解説：
Technical explanation
The official IPAM documentation expressly states that the safest way to change IPAM mode is to install a fresh Kubernetes cluster using the required new IPAM configuration. A live cluster already contains allocated workload addresses, node routing state, Cilium endpoint state, service state, and potentially cloud-provider resources that depend on the active allocator. Replacing the allocator in place can invalidate these assumptions and cause persistent connectivity disruption rather than merely a short agent restart.
Updating a Kubernetes Node object does not generally convert Cilium's IPAM mode. The responsible resource and allocation behavior depend on the selected mode: Kubernetes host-scope IPAM, cluster-pool IPAM, multi-pool IPAM, CRD-backed modes, and cloud-specific allocators manage address information differently. Restarting agents after changing a configuration value likewise does not constitute a safe migration plan, because existing endpoints and routes may retain state created under the former allocator.
Cilium advises against changing the IPAM mode of an existing cluster unless a specifically documented migration procedure applies. The currently documented exception is migration from cluster-pool IPAM to multi-pool IPAM. As the question provides no such constrained scenario, D is the unambiguously safest answer.

質問 # 56
What is the issue with the following egress gateway manifest specification?
Egress gateway manifest exhibit
正解：A
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 # 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：C
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
What is the purpose of the 12 Announcements" feature?
正解：D
解説：
Technical explanation
The question's "12 Announcements" wording is a source transcription error for L2 Announcements . This feature makes Kubernetes Services visible and reachable to clients on the local Layer 2 network, particularly in on-premises, office, campus, or bare-metal environments that do not use BGP-based service advertisement.
Cilium responds to ARP requests for IPv4 Service addresses and NDP requests for IPv6 addresses. A selected node advertises the LoadBalancer IP or ExternalIP using its MAC address and receives traffic for that virtual IP. Cilium then applies its service load-balancing functionality to forward the connection to an appropriate backend. Leadership is coordinated so that one node advertises a given Service at a time, and the virtual IP can move to another eligible node after failure.
The feature is not intended to provide general Layer 2 multicast, making A incorrect. DNS service discovery is handled through Kubernetes DNS and is independent of L2 announcements, eliminating C. It also does not define Layer 2 security policies, so D is incorrect.
Thus, the purpose is external Service reachability on the local area network, exactly as described by B.

質問 # 59
Which encapsulation protocols are supported when configuring Cilium in tunnel mode?
正解：C
解説：
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.
