CloudNetX study guide
CloudNetX · Work through your exam, one topic at a time.
CloudNetX is a CompTIA certification, exam series code CNX-001, version V1, launched February 18, 2025. It validates the ability to design and implement secure, scalable networking solutions in hybrid environments, with emphasis on security design, network monitoring, performance optimization, and advanced troubleshooting, including hands-on skills such as Zero Trust implementation. The CloudNetX study guide has 4 sections and about 1,774 words.
01Network Architecture Design
Network architecture design tests whether you can turn application and business requirements into a hybrid cloud topology that is addressable, reachable, resilient and affordable. Questions rarely ask for a definition; they hand you constraints - number of virtual networks, regions, on-premises sites, latency targets, inspection requirements - and expect one defensible design with the trade-offs stated.
465 words, about 2 min02Network Security
Network security here is about controlling path, identity and inspection in environments where the perimeter is a set of policy attachments rather than a firewall at the building edge. Scenarios typically ask you to choose between security groups and network ACLs, decide where TLS inspection belongs, or justify a private endpoint over an internet-facing endpoint with an IP allowlist.
442 words, about 2 min03Network Operations, Monitoring, and Performance
This domain covers how you know the network is healthy, how you prove it with data, and how you keep latency, throughput and cost inside their targets. Questions present an SLO miss, a cost spike or a quota warning and ask which telemetry you would use and what you would change.
431 words, about 2 min04Network Troubleshooting
Troubleshooting asks you to move from symptom to cause with a repeatable method, in a system where you may not own every hop. Expect scenarios with intermittent failures, one-directional traffic, breakage immediately after a change, and performance that degrades only under load.
