Exam Overview
The CompTIA Network+ N10-008 exam is designed to test your knowledge across five domains. These domains cover everything from basic networking concepts to more advanced topics like security and troubleshooting. Here’s how the exam is structured:
1. Networking Fundamentals – 24%
2. Network Implementations – 19%
3. Network Operations – 16%
4. Network Security – 19%
5. Network Troubleshooting – 22%
The exam consists of 90 questions, which are a mix of multiple-choice and performance-based questions, with a time limit of 90 minutes. A passing score is 720 out of 900. Ideally, you should have 9-12 months of hands-on experience working in a junior network administrator or network support role before taking the exam.
Domain 1: Networking Fundamentals (24%)
The first domain of the CompTIA Network+ N10-008 Exam is Networking Fundamentals, which makes up 24% of the exam content. This domain covers the foundational concepts of networking, including the OSI model, network topologies, IP addressing, and common protocols.
Key Topics to Focus On:
-
OSI Model: You need to understand the seven layers of the OSI model (Physical, Data Link, Network, Transport, Session, Presentation, and Application). Each layer plays a vital role in how data is transmitted across a network.
-
IP Addressing: Be sure to know how to configure both IPv4 and IPv6 addresses, including subnetting, CIDR notation, and the differences between public and private IP addresses.
-
Cables and Connectors: Study the types of cables (e.g., twisted pair, coaxial, fiber) and connectors used in networks. Understanding the specifications, such as Cat5e, Cat6, and fiber optic standards, is crucial.
-
Common Ports and Protocols: Get familiar with protocols like HTTP, HTTPS, DNS, DHCP, and FTP. You’ll also need to know the common port numbers associated with these protocols (e.g., 80 for HTTP, 443 for HTTPS, 53 for DNS).
Study Tip: Take the time to memorize the OSI model and practice configuring IP addressing schemes. CompTIA Network+ Practice Tests can help you assess your knowledge of these foundational concepts, giving you a good sense of where you stand before the actual exam.
Domain 2: Network Implementations (19%)
In this domain, you’ll need to demonstrate your ability to configure and deploy networks. This section makes up 19% of the exam and covers everything from network devices to wireless configurations.
Key Topics to Focus On:
Networking Devices: Learn how to configure and manage essential devices like switches, routers, access points, and firewalls. You’ll also need to know the differences between Layer 2 and Layer 3 switches, as well as how to configure VLANs and trunking.
Routing Technologies: Study the difference between static and dynamic routing protocols. You’ll encounter protocols like RIP, OSPF, BGP, and EIGRP, each with its unique strengths and use cases.
Ethernet Switching: Understand how Ethernet standards work, including features like port aggregation, power over Ethernet (PoE), link aggregation, and spanning tree protocol. VLAN configurations are also critical in this domain.
Wireless Standards: Familiarize yourself with the 802.11 wireless standards, including Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax). You’ll also need to understand channel bonding, frequency ranges (2.4 GHz vs. 5 GHz), and encryption standards for wireless networks.
Study Tip: For this domain, hands-on experience is key. Practice setting up VLANs, configuring routers and switches, and experimenting with different wireless settings. Use network simulators or real lab equipment if possible to reinforce these concepts.
Domain 3: Network Operations (16%)
Network Operations covers the ongoing tasks needed to monitor, manage, and ensure the availability of networks. This domain accounts for 16% of the exam and focuses on performance metrics, logs, and documentation.
Key Topics to Focus On:
Monitoring and Performance Metrics: Learn how to monitor network performance using metrics like latency, jitter, bandwidth, and packet loss. You’ll also need to know how to use tools like SNMP for monitoring devices and logs.
Network Documentation: Understand the importance of documentation in network operations. This includes creating logical and physical network diagrams, as well as documentation for device configurations, IP addressing schemes, and network policies.
Business Continuity and Disaster Recovery: Be familiar with backup strategies, high availability solutions, and disaster recovery plans. Concepts like redundancy, load balancing, and mean time to recovery (MTTR) will appear in this domain.
Study Tip: Practice using network monitoring tools like Wireshark and NetFlow analyzers to get a feel for network performance management. You should also get comfortable with reviewing logs and understanding their impact on network operations.
Domain 4: Network Security (19%)
With the growing emphasis on cybersecurity, Network Security plays a significant role in the CompTIA Network+ exam. This domain represents 19% of the exam content and focuses on securing networks through best practices and technologies.
Key Topics to Focus On:
Authentication Methods: Know the various methods of authentication, including RADIUS, TACACS+, multifactor authentication (MFA), and single sign-on (SSO). You should also be familiar with 802.1X and network access control (NAC).
Firewall and VPN Configuration: Study how to configure firewalls, access control lists (ACLs), and VPNs. Be familiar with site-to-site VPNs, remote access VPNs, and the security implications of using them.
Common Attacks and Mitigations: You’ll need to understand different types of attacks, such as man-in-the-middle, denial-of-service (DoS), phishing, and SQL injection. Know how to mitigate these attacks using techniques like encryption, segmentation, and patch management.
Study Tip: Use this Practice Tests to evaluate your understanding of network security principles. Additionally, create test environments where you can configure firewalls, VPNs, and access controls to get hands-on experience with these technologies.
Domain 5: Network Troubleshooting (22%)
Network Troubleshooting is the second-largest domain, covering 22% of the exam. It’s focused on identifying and resolving common network issues.
Key Topics to Focus On:
Troubleshooting Methodology: Learn the steps involved in network troubleshooting: identifying the problem, establishing a theory, testing the theory, implementing a solution, and documenting findings.
Common Network Issues: Be prepared to troubleshoot issues related to cabling (e.g., attenuation, interference), IP configuration problems (e.g., incorrect gateway or subnet mask), and hardware failures (e.g., bad NICs or routers).
Network Tools and Commands: Master tools like ping, traceroute, netstat, and tcpdump. You should also know how to use a cable tester, multimeter, and Wi-Fi analyzer to diagnose connectivity problems.
Study Tip: The best way to improve your troubleshooting skills is by solving real problems. Work through network scenarios where you troubleshoot common issues. Use lab environments or simulators to practice with the different tools available.
