Q20. Please review the output of cilium status below and answer the question that follows. Please note, the output has been modified for accessibility purposes.

Question 2 cilium status exhibit
Assume the cluster is healthy. What is correct about the ci 1 ium status command output above?

The Kubernetes cluster where Cilium has been deployed should consist of four nodes.

When specific Cilium features require Layer 7 processing, the Cilium agent starts an Envoy proxy as a separate process within the Cilium agent pod.

The component that allows you to query multiple Hubble instances simultaneously and aggregate the results is unhealthy.

Cilium has been installed and configured in a multi-cluster deployment model to provide load balancing and service discovery.

Q21. Which of the following best describes how eBPF is used within Cilium9

Cilium utilizes eBPF to gather real-time insights Into network traffic, Including data on latency, bandwidth, and data flows between services. This data Is exposed through a user interface and can be used for network troubleshooting and optimization.

Cilium uses eBPF to provide a reliable and scalable DNS infrastructure for Kubernetes clusters, enabling seamless communication between services and facilitating service discovery within the cluster

Cilium is a security-related project that utilizes eBPF for real-time network security analysis. It employs eBPF to detect and respond to network security threats by inspecting network traffic.

Cilium leverages eBPF to enforce network security policies at the kernel level. Security rules are translated into eBPF programs that are attached to kernel network hooks, allowing packet filtering based on these rules.

Q22. What are the differences between Ingress and Gateway API?

Ingress and Gateway API serve the same purpose, but they are Just different names for the same Kubernetes resource. Ingress is used in older Kubernetes versions, while Gateway API is the updated version for modern clusters, but the underlying functionality is identical.

Ingress primarily targets exposing HTTP applications with a simple, declarative syntax. Gateway API exposes a more general API for proxying that can be used for more protocols than just HTTP, and models more infrastructure components to provide better deployment and management options for cluster operators.

Cilium offers seamless integration with the Gateway API, enhancing Kubernetes networking and security through advanced features powered by eBPF. This integration provides a robust solution for network management. In contrast, Ingress relies on IPtables for its functionality.

Gateway API is primarily used for internal cluster routing, while Ingress is exclusively for external traffic management. Gateway API does not support routing for internet-exposed services, whereas Ingress is specifically designed for that purpose.

Q23. What is true about Layer 7 protocol visibility in Cilium?

DNS visibility in available in the ingress direction only.

It can be enabled by deploying a standard Kubernetes network policy.

It results in traffic being proxied through an Envoy instance.

It supports any Layer 7 protocols, including SSH, Telnet and FTP.

Q24. A Kubernetes cluster is not currently running Cilium as a CNI, but the user would like to benefit from Hubbies observability capabilities on your cluster. Which one of the following options is NOT possible?

Migrating to Cilium and Hubble by reconfiguring /etc/cni/net .6/ to point to Cilium and restarting the nodes, accepting an outage.

Install Hubble on the cluster without Cilium. Hubble can be deployed in a standalone model by downloading and installing the Hubble binary

Install Cilium and Hubble on top of the cluster in a CNI chaining model, without disrupting the existing CNI.

Migrating to Cilium and Hubble on a node-by-node basis, without requiring a complete cluster outage, by using Dual Overlays.

Q25. How does Cilium primarily improve security in Kubernetes clusters?

By using API Gateway configurations.

By securing and encrypting database data.

By providing backup solutions for persistent volumes.

By implementing network policies at multiple OSI model layers.

Q26. You are tasked to install Cilium and enable transparent encryption in a cluster in which the following conditions applies:
# Internal cluster traffic is IPv6-only
# The current cluster is running on 5001 nodes
# The cluster is planned to connect to another cluster which has 5001 nodes through Cluster Mesh What are your recommendations regarding transparent encryption?

Enable the wireguard transparent encryption.

Enable the IPSec transparent encryption.

Clusters have too many nodes for transparent encryption.

Transparent encryption requires an IPv4-only network.

Q27. a requirement to achieve service discovery and load balancing across clusters with Cluster Mesh?

Each cluster must be in the same geographical location.

All clusters must run the same distribution and version of Kubernetes.

All clusters must run the same version of Cilium.

Each cluster must be configured with a unique cluster ID.

Q28. 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?

Yes. but you need to change the cluster name and cluster ID before

No, Cilium certificate authority must be the same to deploy a cluster mesh. You cannot change that after installation

No. cluster name and cluster ID must be different. You cannot change that after installation.

Yes, but you need to upgrade cilium version of Cluster B

Q29. The Cilium Agent is deployed as part of the Cilium installation. What of the following is true about the Cilium Agent?

Cilium Agent registers the Custom Resource Definitions that Cilium uses.

Cilium Agent creates the CiliumEndpoint objects for each pod in the cluster.

Cilium Agent manages IP addresses for LoadBalancer type services (if LB IPAM is used).

Cilium Agent synchronizes Kubernetes nodes information to the shared KVStore.

Q30. Which one of the following Cilium Network Policies follow the correct syntax?
A)

Question 17 option A

Option B

Option C

Option D

Q31. Which question does Hubble provide the information to answer?

What is the configuration of Cilium B6P?

Which container database query ran the longest?

Which containers have the highest CPU utilization?

Which services had connections blocked due to network policy?

Q32. What is true about WireGuard encryption on Cilium?

Packets are encrypted when they are destined to the same node from which they were sent. This is to ensure confidentiality of traffic within the node.

It provides encryption for node-to-node, pod-to-node, node-to-pod, and pop-to-pod traffic as long as the pods are on different nodes.

When running in the tunneling mode, pod-to-pod traffic will be sent over the WireGuard tunnel before being transmitted over the overlay tunnel.

When WireGuard is enabled in Cilium, each pod will establish a secure WireGuard tunnel between it and all other known pods in the cluster.

Q33. Which one of the following service mesh features and use cases is natively supported by Cilium?

AP| request limiting

API authorization

Layer 7 Load Balancing of gRPC

Fault injection, such as injection of delay

Q34. Which encapsulation protocols are supported when configuring Cilium in tunnel mode?

MPLS and Geneve

VXLAN and Geneve

OTV and STT

EVPN and VXLAN

Q35. Which Cilium command should you execute to gather network-related troubleshooting information from your Kubernetes cluster?

cilium debuginfo

cilium status –verbose

cilium bugtool

cilium sysduwp

Q36.

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.

Observability of network flows via a graphical user interface has yet to be enabled for this particular cluster

The component responsible for registering the CRDs used by Cilium is healthy.

The operator has been deployed as a DaemonSet.

Only a single operator replica can be deployed on the cluster.
