Q42. Which of the following best describes the role of the Cilium Operator in a Kubernetes cluster?

It manages BPF program compilation and loading.

It performs cluster-wide tasks such as global IP address management.

It acts as a gateway for external traffic into the cluster.

It handles the enforcement of network policies within each node.

Q43. Which of the following are common use cases for a service mesh?
(Choose Two)

Automated service discovery and load balancing

Centralized management of network policies

Offloading SSL processing from application pods

Managing stateful applications

Q44. What challenges does Cilium Cluster Mesh address in a multi-cluster setup?
(Choose Two)

Managing consistent security policies across clusters

Integrating clusters with different network topologies

Ensuring high availability of services across clusters

Reducing operational overhead in multi-cluster management

Q45. What are the key features of Cilium’s application-aware policies in a service mesh?
(Choose Two)

They allow enforcement based on HTTP methods.

They require external load balancers.

They operate independently of Kubernetes labels.

They support filtering based on application-level data.

Q46. What distinguishes eBPF-based platforms from IPtables-based platforms regarding security policy enforcement?
(Choose Two)

eBPF can update security policies without restarting applications

eBPF supports complex, stateful rules that are difficult with IPtables

IPtables require manual intervention for each policy update

IPtables provide better visibility into encrypted traffic

Q47. What benefits does the Gateway API offer over traditional Ingress in a service mesh architecture?

Higher performance and reduced latency

Simplified routing logic

Increased routing flexibility

Compatibility with non-Kubernetes environments

Q48. Which capabilities should you expect when using Hubble from the command line?
(Choose Two)

Direct editing of network security policies

Retrieving historical network traffic data

Generating real-time alerts based on observed activities

Observing live network flows and metadata

Q49. Which functionalities are enabled by eBPF in Cilium?
(Choose Two)

Direct manipulation of network packets in the kernel

Centralized management of Kubernetes nodes

Stateful firewall capabilities at the kernel level

Automated IP address assignment in Kubernetes

Q50. Which of the following Cilium CLI commands are used to monitor the status of Cilium within the cluster?
(Choose Two)

cilium status

cilium monitor

cilium check

cilium inspect

Q51. Cilium’s Policy Rule Structure allows for which of the following features?

Strict enforcement based only on network ports

Defining rules that apply to specific DNS names

Policies that automatically expire after a set duration

Rules that can only be applied within the same namespace

Q52. What is the role of the cilium preflight command?

It checks system requirements before installing Cilium.

It prepares Kubernetes nodes for Cilium installation.

It cleans up any previous Cilium installation.

It initiates the installation of Cilium.

Q53. How does eBPF enhance network observability in Cilium?

By using external tools to monitor traffic

Through deep packet inspection at the kernel level

By logging all network events to a central database

eBPF does not enhance observability directly

Q54. What distinguishes a sidecar-based architecture from a sidecarless one in the context of a service mesh?

Sidecar-based architecture requires more memory allocation.

Sidecarless architecture has better support for multi-cloud environments.

Sidecar-based architecture involves deploying a proxy alongside each service instance.

Sidecarless architecture depends on external hardware for service communication.

Q55. How does encrypting traffic in transit with Cilium enhance security in a service mesh environment?

It prevents unauthorized data access from within the cluster

It secures data against external threats only

It enables compliance with external audit requirements

It replaces the need for application-level encryption

Q56. What is the benefit of using sidecarless architecture in a service mesh managed by Cilium?

Reduced latency and overhead

Easier configuration of network policies

Simplified monitoring of service interactions

Enhanced logging capabilities
