Cilium Certified Associate (CCA) Practice Exams 4+1

Become confident in certifying as a Cilium Certified Associate (CCA) with abundant practice exams.

Some of these practice questions are more challenging than the actual exam questions. By solving these difficult problems, you can better prepare for the real exam. This is particularly true for Network Policy (18% weight) and Architecture sections. If you can score above 75% (the passing threshold) on the mock exam, you can be confident that you will pass the actual exam. Don't worry if you get questions wrong. The strategy is to fail fast, read the explanations and reference materials to understand the concepts, then solve similar problems again to prepare for the exam in a short period of time.

This comprehensive practice exam collection contains 60 carefully crafted questions covering all essential CCA domains: Architecture (20%), Network Policy (18%), Service Mesh (16%), Network Observability (10%), Installation and Configuration (10%), Cluster Mesh (10%), eBPF (10%), and BGP and External Networking (6%). Each question includes detailed explanations for all answer choices, not just the correct one, helping you understand why certain options are wrong and reinforcing core concepts. The questions range from basic Cilium agent architecture and IPAM modes to advanced CiliumNetworkPolicy rules with toFQDNs selectors and DNS-based filtering, Hubble CLI commands for Layer 7 flow analysis, Gateway API configuration for ingress routing, and cluster mesh setup for cross-cluster service discovery. You'll encounter real-world scenarios involving eBPF datapath modes (veth vs ipvlan), policy enforcement modes (default, always, never), identity-based security model with CIDR and endpoint selectors, mTLS encryption for pod-to-pod traffic, and BGP routing for external network integration. The practice materials are based on official Cilium documentation, covering CLI usage (cilium status, connectivity test, hubble observe), Helm installation options, and networking patterns that professional Kubernetes network engineers use daily. Each mock exam follows the same format as the official CCA certification, ensuring you're familiar with question styles and time constraints before taking the actual test.
