The CompTIA Network+ N10-009 exam introduces automation and cloud networking as core domains, reflecting how real-world networks are built and operated today. If you are preparing for this exam, you need to understand what changed and how to study efficiently. This guide breaks down the new automation and cloud content, shows practical examples, and offers a focused study plan to pass on your first attempt. Automation is no longer optional—it is a required skill for network engineers. Cloud networking knowledge is essential for hybrid environments. Security practices now integrate with cloud and automation. This exam tests these modern realities.
Exam Overview
The N10-009 exam tests your ability to design, configure, manage, and troubleshoot wired and wireless networks. It includes performance-based questions alongside multiple-choice items. According to CompTIA, the exam has approximately 90 questions with a time limit of 90 minutes. The passing score is 720 on a scale of 100-900. The domains are: Networking Concepts (23%), Implementation (19%), Operations (18%), Security (20%), and Troubleshooting (20%) CompTIA.
What makes N10-009 different is its increased focus on modern network environments, including cloud and automation. CompTIA states this version covers more extensive discussion of factors related to physical network implementations and modern network environments CompTIA.
Performance-based questions require you to perform tasks in a simulated environment. You might need to configure a router, troubleshoot a connectivity issue, or analyze a network diagram. These questions test practical skills, not just theoretical knowledge. They often take more time, so manage your time wisely during the exam.
Multiple-choice questions test your understanding of concepts, protocols, and best practices. Read each question carefully and look for keywords such as “best,” “most,” or “first.” Use the process of elimination to narrow down choices. Some questions may have multiple correct answers, so read all options before selecting.
Security is a major domain, covering 20% of the exam. You need to understand network hardening, firewalls, VPNs, and secure access practices. Security questions often present a scenario and ask which solution best addresses the risk. Be prepared to analyze security policies and identify vulnerabilities.
Automation Changes
Automation is no longer optional—it is a required skill for network engineers. The N10-009 exam expects you to understand basic scripting concepts, configuration management tools, and how automation applies to network operations. This aligns with industry trends where network automation reduces manual errors and speeds up deployments. Employers now expect network engineers to have some automation skills. This exam reflects that demand.
You should be familiar with the fundamentals of Python or other scripting languages used in network automation. The exam does not require you to write complex scripts, but you must recognize syntax and understand how scripts interact with network devices. For example, a question might ask which Python library is commonly used to connect to network devices via SSH—paramiko is a standard answer. Netmiko is another popular library built on top of paramiko that simplifies network automation tasks.
Configuration management tools such as Ansible are also in scope. You should know what Ansible is, how it uses playbooks, and why it is agentless. A typical exam question could describe a scenario where you need to push the same configuration to 50 switches and ask which tool fits best. Ansible would be the correct choice because it uses SSH and does not require agents on the target devices. Ansible uses YAML for playbooks, which are easy to read and write. You should understand the basic structure of a playbook, including tasks, modules, and hosts.
Other automation tools may appear on the exam, including Puppet and Chef. These tools use agents and are more common in server environments, but you should know they exist and their basic differences. Compare them to Ansible, which is agentless. A question might ask which tool uses a master-agent architecture—Puppet or Chef would be correct. Understanding these differences helps you choose the right tool for the job.
Additionally, you must understand the concept of Infrastructure as Code (IaC) and how tools like Terraform or CloudFormation are used to provision network resources in cloud environments. The exam may test your ability to identify which tool is appropriate for automating cloud infrastructure deployment. Terraform is provider-agnostic, while CloudFormation is AWS-specific. You should know the difference and when to use each. IaC treats infrastructure like software, enabling version control, repeatability, and scalability.
Cloud Networking
Cloud networking is now a major component of Network+. You need to understand how networks are structured in public cloud providers such as AWS, Azure, and Google Cloud. This includes virtual private clouds (VPCs), subnets, routing, and network security groups. Cloud networking differs from traditional on-premises networking in several ways. It is software-defined, highly scalable, and often uses different terminology. However, the underlying principles of IP addressing, routing, and security remain the same.
In AWS, you should know what a VPC is, how subnets work, and the purpose of route tables and internet gateways. A VPC is a virtual network dedicated to your AWS account. It is isolated from other virtual networks in the AWS Cloud. You can launch AWS resources, such as EC2 instances, into your VPC. Subnets segment a VPC into multiple networks. Route tables determine where network traffic is directed. Internet gateways allow communication between instances in your VPC and the internet.
For Azure, understand Azure Virtual Network, subnets, and network security groups. An Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. VNet enables many types of Azure resources, such as Azure VMs, to securely communicate with each other, the internet, and on-premises networks. Subnets segment VNet into smaller networks. Network Security Groups (NSGs) filter network traffic to and from Azure resources.
For Google Cloud, learn about VPC networks, subnets, and firewall rules. A VPC network is a virtual version of a physical network, implemented in Google Cloud. Subnets partition a VPC network into ranges of IP addresses. Firewall rules control traffic to and from instances. Google Cloud uses hierarchical firewall policies, allowing you to define rules at the organization or folder level.
The exam may present a diagram and ask which component allows resources in a VPC to communicate with the internet—an internet gateway is the answer. Or it might ask which service controls inbound and outbound traffic at the subnet level—network security groups or firewall rules are correct.
Hybrid cloud networking is also relevant. You should understand how to connect on-premises networks to cloud environments using VPN tunnels or direct connect services. A question might ask which service provides a dedicated, private connection between your data center and AWS—AWS Direct Connect is the correct choice. Azure ExpressRoute provides a similar service for Azure. Google Cloud Interconnect connects your on-premises network to Google’s network.
Furthermore, you must be comfortable with cloud-native networking services such as load balancers, NAT gateways, and CDN. These services are tested at a conceptual level—you need to know what they do and when to use them, not necessarily how to configure every parameter. Load balancers distribute traffic across multiple targets. NAT gateways allow instances in a private subnet to connect to services outside your VPC but prevent unsolicited connections. CDNs cache content at edge locations to reduce latency.
What’s New vs. N10-008
Comparing N10-009 with its predecessor N10-008 reveals several important changes. CompTIA officially notes that N10-009 provides more extensive coverage of modern network environments and physical network implementations CompTIA. This means the exam is more aligned with current industry practices and technologies.
Automation and scripting are new or expanded topics. While N10-008 touched on automation, N10-009 makes it explicit, requiring familiarity with tools and basic scripting concepts. You will encounter questions about configuration management, scripting libraries, and Infrastructure as Code. This reflects the growing importance of automation in network operations. Networks are too complex to manage manually, and automation skills are now essential.
Cloud networking is also more prominent. In N10-008, cloud was a smaller portion; now, it is integrated across multiple domains, especially in implementation and security. You need to understand cloud networking concepts, services, and hybrid connectivity. The exam may include scenarios where you must design a cloud network or troubleshoot connectivity issues between on-premises and cloud resources.
Security has been updated to include modern threats and mitigation techniques relevant to cloud and automated environments. For example, you need to understand how to secure API calls, implement zero-trust concepts, and use cloud-native security services. The exam also places more emphasis on network hardening and compliance. Zero-trust is a security model that assumes no implicit trust. Every access request is verified, regardless of where it originates.
Professor Messer’s breakdown highlights that N10-009 removes some legacy topics and adds newer ones such as SD-WAN, wireless security improvements, and updated routing protocols Professor Messer. SD-WAN is a software-defined approach to managing wide-area networks. It improves performance and reduces costs by intelligently routing traffic across multiple connections. Wireless security now includes WPA3, the latest Wi-Fi security protocol. Routing protocols updates reflect current industry usage.
Legacy topics that may receive less attention include older technologies that are fading from use. For example, Token Ring and FDDI are unlikely to appear. This shift allows the exam to focus on relevant, up-to-date content. Always check the official exam objectives for the most accurate information on what is covered.
Study Plan for 2026
To pass N10-009 in 2026, follow a structured study plan that balances theory with hands-on practice. Here is an 8-week roadmap:
Week 1-2: Networking Fundamentals & OSI Model
Review IP addressing, subnetting, OSI and TCP/IP models. Ensure you can subnet quickly and identify which OSI layer a given protocol operates at. Use practice questions to reinforce these basics. Subnetting is a critical skill. Practice converting between decimal and binary. Understand the differences between Class A, B, and C networks. Learn about CIDR notation and how it simplifies IP address allocation.
The OSI model has seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer has a specific function. For example, the Network layer handles logical addressing and routing, while the Transport layer ensures reliable data delivery. The TCP/IP model has four layers: Network Access, Internet, Transport, and Application. Know how these models relate to each other.
Week 3: Routing & Switching
Study static and dynamic routing (RIP, OSPF, EIGRP basics), VLANs, STP, and switching concepts. Set up a lab using GNS3 or Packet Tracer to configure VLANs and verify routing tables. Routing determines how data packets move across networks. Static routing is manually configured, while dynamic routing protocols automatically learn routes.
VLANs segment a broadcast domain. They improve security and performance by isolating traffic. Spanning Tree Protocol (STP) prevents loops in switched networks. Understand how STP elects a root bridge and blocks redundant paths. Switching operates at Layer 2 and uses MAC addresses to forward frames.
Week 4: Wireless & Physical Network
Learn Wi-Fi standards (802.11a/b/g/n/ac/ax), channels, security (WPA3), and antenna types. Understand cabling standards (Cat6, fiber) and installation best practices. Wi-Fi standards define speed, frequency, and range. 802.11ax, also known as Wi-Fi 6, offers higher throughput and better performance in dense environments.
Wireless security has evolved from WEP to WPA, WPA2, and now WPA3. WPA3 provides stronger encryption and protection against offline attacks. Channels determine which frequency band Wi-Fi uses. Avoid overlapping channels to reduce interference. Antenna types include omnidirectional, which radiates in all directions, and directional, which focuses signal in a specific direction.
Physical cabling includes twisted-pair copper and fiber optic. Cat6 is common for gigabit Ethernet. Fiber supports higher speeds and longer distances. Proper installation ensures performance and reliability. Follow best practices for cable management, labeling, and testing.
Week 5: Cloud Networking
Create free-tier accounts on AWS and Azure. Build a VPC with subnets, configure route tables, and deploy a simple web server. Practice connecting to instances via SSH. This hands-on experience will cement cloud concepts. Building a cloud network from scratch gives you practical skills that cannot be gained from reading alone.
Deploying a web server involves several steps: creating a VPC, adding subnets, configuring security groups, launching an instance, and connecting to it. Each step tests your understanding of cloud networking components. Use the cloud provider’s documentation to guide you through the process.
Week 6: Automation & Scripting
Write a simple Python script using paramiko to log into a device and run a command. Learn basic Ansible playbook syntax. You don’t need to become a developer, but you should be able to read and understand scripts. Automation saves time and reduces errors. Even a basic script can automate repetitive tasks.
Start with a simple script that logs into a router and displays the running configuration. Then try a script that changes a configuration. For Ansible, create a playbook that configures a VLAN on multiple switches. Practice reading YAML and understanding how tasks are executed.
Week 7: Security & Troubleshooting
Focus on network hardening, firewalls, VPNs, and troubleshooting methodologies. Use practice exams to identify weak areas. Security is a broad topic, so prioritize the most common threats and mitigations. Learn how to configure firewall rules, set up a site-to-site VPN, and implement access control lists.
Troubleshooting requires a systematic approach. Use the OSI model to isolate problems. Start at Layer 1 and work up. Check physical connections, then move to data link, network, and so on. Practice with lab scenarios to build your troubleshooting skills.
Week 8: Review & Practice Exams
Take multiple full-length practice exams. Review every question you missed. Time yourself to build exam endurance. Practice exams simulate the real test environment. They help you manage time and identify knowledge gaps. Reviewing missed questions is more valuable than getting them right. Understand why your answer was wrong and why the correct answer is right.

Final Tips
On exam day, read each question carefully. Look for keywords such as “best,” “most,” or “first.” If you encounter performance-based questions, stay calm—they are often simulations where you must configure or troubleshoot a network scenario. Use the process of elimination and manage your time wisely.
Do not spend too much time on a single question. If you are unsure, mark it and move on. You can return to it later if time permits. Performance-based questions often take longer, so budget your time accordingly. Remember, you have 90 minutes for approximately 90 questions. This averages one minute per question, but performance-based items may require more time.
Get a good night’s sleep before the exam. Arrive early to the testing center or ensure your remote testing environment is ready. Bring two forms of identification if testing at a center. For remote testing, check your equipment and internet connection beforehand to avoid technical issues.
Remember, N10-009 tests modern networking skills. Automation and cloud are not just add-ons—they are integral to the exam. By studying these topics and practicing with real labs, you will be well-prepared to pass and advance your networking career.
