CCA Exam Preparation — Cilium Certified Associate
Cilium and eBPF demystified: next-generation Kubernetes networking, from NetworkPolicies to Hubble, all the way to the CCA exam.
Objectives
- Pass the CCA multiple-choice exam
- Explain what eBPF concretely changes for Kubernetes networking
- Write L3/L4 and L7 network policies with Cilium
- Observe flows in real time with Hubble
Audience
Network, platform, and SRE engineers curious about what replaces iptables in modern clusters.
Prerequisites
- Hands-on Kubernetes experience, including its networking objects (Services, NetworkPolicies)
- IP networking notions: routing, L3/L4/L7 layers
Program
Cilium architecture
- eBPF: principle and benefits
- Agent, datapath, and identities
- Installation and deployment modes
Network policies
- Kubernetes NetworkPolicies vs CiliumNetworkPolicies
- L7 rules: HTTP, DNS
- Reasoning in identities rather than IP addresses
Observability with Hubble
- Flows, service map, and CLI
- Diagnosing a refused connection
Service mesh, cluster mesh, and mock exam
- Load balancing and kube-proxy replacement
- Connecting multiple clusters
- Annotated mock multiple-choice test
