Comptia Network+ Practice Tests - N10-009 Certification

The CompTIA Network+ N10-009 exam is designed to validate the skills and knowledge necessary to configure, manage, and troubleshoot networks in a professional environment. Here are the primary domains and topics covered in the exam:

---

1. Networking Fundamentals (24%)

• Network Concepts:
  • Compare and contrast the Open Systems Interconnection (OSI) and Transmission Control Protocol/Internet Protocol (TCP/IP) models.
  • Understand key network protocols such as IP, TCP, UDP, ICMP, and ARP.
• Networking Hardware:
  • Types of network devices: switches, routers, access points, firewalls, etc.
  • Cable types: copper (UTP/STP) and fiber (single-mode/multi-mode).
• Networking Concepts:
  • IP addressing (IPv4 and IPv6).
  • Subnetting, CIDR (Classless Inter-Domain Routing), and address allocation.
  • Network topologies: star, mesh, hybrid, etc.

---

2. Network Implementations (19%)

• Routing and Switching:
  • Compare routing protocols (e.g., OSPF, RIP, BGP).
  • VLANs (Virtual Local Area Networks) and inter-VLAN routing.
• Wireless Networking:
  • Wireless standards (802.11 a/b/g/n/ac/ax).
  • Configure and secure wireless networks (SSID, encryption, WPA3, etc.).
• WAN Technologies:
  • Internet connection types: DSL, cable, fiber, satellite.
  • VPN and tunneling protocols.

---

3. Network Operations (16%)

• Monitoring and Management:
  • Network monitoring tools: SNMP, Syslog, NetFlow.
  • Configure and review logs for performance metrics and security.
• Business Continuity:
  • Backup and recovery plans.
  • Implement disaster recovery measures.
• Policies and Procedures:
  • IT documentation, diagrams, and standard operating procedures (SOPs).

---

4. Network Security (19%)

• Network Vulnerabilities:
  • Common vulnerabilities and risks (phishing, DoS/DDoS attacks).
• Security Devices:
  • Firewalls, IDS/IPS, proxies, VPN concentrators.
• Access Control:
  • Authentication methods (e.g., RADIUS, TACACS+).
  • Secure wireless access: MAC filtering, 802.1X.
• Network Hardening:
  • Security best practices: updating firmware, disabling unused ports.

---

5. Network Troubleshooting (22%)

• Tools and Techniques:
  • Command-line tools: ping, traceroute, ipconfig, nslookup, etc.
  • Network diagnostic tools: Wireshark, Netstat, and Nmap.
• Troubleshooting Methodologies:
  • Identify and resolve common network issues: connectivity, performance, and security.
• Performance Optimization:
  • Traffic shaping, QoS, and load balancing.
• Device Configuration:
  • Identify and rectify misconfigurations in network devices.
