Among the definitions provided for the entities host, remote-node, cluster, and all, which description is accurate in the context of Cilium network policy?

• A. The all entity corresponds to all endpoints outside of the cluster. Allowing to all Is identical to allowing to CIDR 0.0.0.0/0.
• B. The host entity Includes the local host. This also includes all containers running in host networking mode on the local host.
• C. The remote-node entity represents endpoints not managed by Cilium. Unmanaged endpoints are considered part of the cluster and are included in the cluster entity.
• D. The cluster entity represents the kube-apiserver in a Kubernetes cluster. This entity represents both deployments of the kube-apiserver: within the cluster and outside of the cluster

Which Cilium command should you execute to gather network-related troubleshooting information from your Kubernetes cluster?

• A. cilium sysduwp
• B. cilium status --verbose
• C. cilium bugtool
• D. cilium debuginfo

Cilium status exhibit
Based on the cilium status output above, what is correct about the Cilium deployment?
For accessibility, the output of the command has been edited.

• A. The component responsible for registering the CRDs used by Cilium is healthy.
• B. The operator has been deployed as a DaemonSet.
• C. Only a single operator replica can be deployed on the cluster.
• D. Observability of network flows via a graphical user interface has yet to be enabled for this particular cluster

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?

• A. No, Cilium certificate authority must be the same to deploy a cluster mesh. You cannot change that after installation
• B. No. cluster name and cluster ID must be different. You cannot change that after installation.
• C. Yes, but you need to upgrade cilium version of Cluster B
• D. Yes. but you need to change the cluster name and cluster ID before

If you are required to block ingress traffic from external IPs for all pods in your cluster, which of the following network policies would be the best fit?

• A. CiliumClusterWideNetworkPolicy
• B. NetworkPolicy
• C. CiliumGlobalPolicy
• D. CiliumNetworkPolicy
