The CompTIA CloudNetX Certification Exam (CNX-001) validates your ability to design, secure, operate, and troubleshoot modern cloud-based network infrastructure. This exam is ideal for network professionals transitioning to cloud environments or expanding their expertise within the CompTIA CloudNetX path. This page provides a clear roadmap of exam topics, question formats, and preparation strategies to help you study efficiently and build confidence before test day.
Use this topic map to guide your study for CompTIA CNX-001 (CompTIA CloudNetX Certification Exam) within the CompTIA CloudNetX path.
The CompTIA CloudNetX Certification Exam uses multiple question types to assess both foundational knowledge and applied decision-making in real-world cloud network scenarios.
Questions progress in difficulty, rewarding deeper understanding and hands-on experience with cloud network operations.
Effective preparation aligns your study schedule with the five core domains, builds practical experience through labs, and reinforces weak areas with targeted practice. A structured, weekly approach helps you retain concepts and apply them under exam-like conditions.

Network Architecture Design and Network Security typically represent the largest portion of the exam, reflecting their importance in real-world cloud deployments. However, all five domains are tested, so balanced preparation across all topics is essential for a strong score.
Architecture decisions (domain 1.0) directly influence security requirements (2.0), operational monitoring strategies (3.0), and troubleshooting approaches (4.0 and 5.0). For example, choosing a multi-region design affects how you implement firewalls, monitor latency, and diagnose cross-region connectivity failures. Understanding these relationships helps you answer scenario questions more effectively.
At least 2-3 years of network administration experience, with some exposure to cloud platforms (AWS, Azure, or GCP), is recommended. Hands-on labs in network design, firewall configuration, and cloud console navigation are invaluable; prioritize labs that simulate real failover events and security incident response.
Many candidates rush through scenario questions without fully reading the context, leading to incorrect decisions. Others neglect Hardware and Network Troubleshooting (domain 5.0) during study, assuming it is less important. Additionally, failing to connect architecture decisions to operational and security outcomes costs points on integrated questions.
Spend 60% of your time on a full-length timed practice test to identify remaining gaps, then use 40% to review explanations and revisit weak domains. Avoid learning new material in the final days; instead, reinforce core concepts and practice pacing to ensure you can complete all questions within the time limit.
SIMULATION
A network administrator needs to resolve connectivity issues in a hybrid cloud setup. Workstations and VMs are not able to access Application A. Workstations are able to access Server B.
INSTRUCTIONS
Click on workstations, VMs, firewalls, and NSGs to troubleshoot and gather information. Type help in the terminal to view a list of available commands.
Select the appropriate device(s) requiring remediation and identify the associated issue(s).
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Firewalls VPN tunnel down
The IPsec tunnel between on-prem Firewall 1 and cloud Firewall 2 (ipip0/ipip2) is down, so no traffic can traverse to the cloud.
Application NSG Misconfigured rule
There's a ''block'' rule for 10.3.9.0/24 192.2.1.0/24, preventing legitimate on-prem clients from reaching Application A.
A network architect must ensure only certain departments can access specific resources while on premises. Those same users cannot be allowed to access those resources once they have left campus. Which of the following would ensure access is provided according to these requirements?
By defining an IP-based geofence around the on-premises network addresses where those resources reside, you ensure that only users connecting from inside the campus IP ranges can reach them. As soon as the same users leave that network (and thus fall outside the geofenced IP block), access is automatically denied.
An administrator logged in to a cloud account on a shared machine but forgot to log out after the session ended. Which of the following types of security threats does this action pose?
By leaving an active session open on a shared machine, an attacker with access to that machine can intercept or hijack the administrator's session tokens or credentials - classic on-path behavior - allowing them to impersonate the admin without needing elevated exploits.
A network engineer is installing new switches in the data center to replace existing infrastructure. The previous network hardware had administrative interfaces that were plugged into the existing network along with all other server hardware on the same subnet. Which of the following should the engineer do to better secure these administrative interfaces?
Segregating management interfaces onto their own dedicated network ensures that administrative access is isolated from general user and server traffic, greatly reducing the attack surface and preventing lateral movement if the production network is compromised.
A cloud engineer is planning to build VMs in a public cloud environment for a cloud migration. A cloud security policy restricts access to the console for new VM builds. The engineer wants to replicate the settings for each of the VMs to ensure the network settings are preconfigured. Which of the following is the best deployment method?
Using an Infrastructure-as-Code template lets you define and version all VM configurations, including network settings, in code that's automatically applied during deployment, eliminating the need for console changes and ensuring consistency across each build.
