CNEpv study guide
CNEpv · Work through your exam, one topic at a time.
The Certified NetExpert Professional (CNE) is an independent, vendor-neutral credential for network engineers who design, operate, secure, and automate modern enterprise and cloud-connected networks. It suits professionals with hands-on experience in routing, switching, security, and monitoring who want to validate a broad, practical skill set rather than a single vendor platform. The CNEpv study guide has 6 sections and about 1,935 words.
01Network Fundamentals, Architecture, and Topologies
This domain tests how data moves from an application to the wire and how topology choices affect failure domains, latency, and policy placement. Expect encapsulation, addressing, subnetting, VLAN boundaries, and architecture patterns such as three-tier, collapsed core, spine-leaf, and hub-and-spoke.
297 words, about 1 min02Routing Protocols and Switching Technologies
This domain tests how switches build forwarding tables and how routers choose paths among connected, static, and dynamic routes. Expect VLAN trunks, STP, EtherChannel, OSPF, EIGRP, BGP, first-hop redundancy, and administrative distance.
325 words, about 2 min03Network Security, Access Control, and Threat Mitigation
This domain tests defense in depth: identity, segmentation, policy enforcement, and detection. Expect AAA, 802.1X, ACL logic, DMZ design, IPsec and TLS, PKI, common attacks, and Layer 2 protections such as DHCP snooping and dynamic ARP inspection.
325 words, about 2 min04Network Operations, Monitoring, and Troubleshooting
This domain tests whether you can operate a network with baselines, backups, time sync, and monitoring, then isolate faults methodically. Expect SNMP, syslog, flow data, packet capture, interface counters, DNS/DHCP checks, and change control.
306 words, about 2 min05Automation, Programmability, and Network Management
This domain tests how modern networks are configured, modeled, and verified programmatically. Expect SDN planes, APIs, data formats, NETCONF/YANG, RESTCONF, Ansible, Git, infrastructure as code, and model-driven telemetry.
325 words, about 2 min06Cloud, Virtualization, and Emerging Network Technologies
This domain tests how cloud and virtualization change network design, trust boundaries, and operations. Expect IaaS, PaaS, SaaS, VPC/VNet constructs, security groups versus NACLs, hybrid connectivity, SD-WAN, NFV, containers, and emerging access technologies.
