Pass CompTIA Network+ in 30 Days: Intensive Study Plan

Passing CompTIA Network+ in 30 days requires disciplined daily study, heavy subnetting practice, and a clear understanding of all five exam domains. This guide maps every day to specific objectives so you can go from beginner-level networking knowledge to exam-ready in one month.

Is 30 Days Enough for Network+?

CompTIA Network+ contains up to 90 questions in a 90-minute window. The passing score is 720 out of 900. Unlike A+, Network+ is a single exam, which means you only need to prepare for one test—a significant advantage on a tight timeline.

The biggest challenge is the breadth of networking topics. You need to understand everything from physical cabling to cloud architectures, from subnetting to network security. Thirty days works if you already have a foundation; it is extremely tight for someone who has never configured a router or assigned an IP address.

Daily Time Breakdown

Week 1: Networking Fundamentals (Days 1-7)

The first week establishes the foundation everything else builds on. If you do not fully understand the OSI model, TCP/IP stack, and IP addressing by day seven, the rest of the plan will be much harder. Spend extra time here if needed.

• Days 1-2: OSI model (all seven layers with protocols at each), TCP/IP model, encapsulation process, network topologies (star, mesh, bus, ring, hybrid).
• Days 3-4: IP addressing—IPv4 classes, CIDR notation, subnet masks, subnetting practice (calculate network ID, broadcast address, usable hosts). Begin daily 15-minute subnetting drills.
• Days 5-6: Cables and connectors—Cat5e, Cat6, Cat6a, fiber (single-mode vs multi-mode), coaxial, T568A/B. Network devices—routers, Layer 2/3 switches, access points, bridges, modems.
• Day 7: Subnetting marathon + 50-question quiz on fundamentals. Score yourself by domain and note weak spots.

Week 2: Network Implementations (Days 8-14)

Week two covers the "how things are built" portion of the exam. Routing, switching, VLANs, and wireless are heavily tested. Expect scenario-based questions that require you to choose the right solution for a given network design problem.

• Days 8-10: Routing concepts—static vs dynamic routing, OSPF, EIGRP, BGP basics, default gateway, routing tables. Switching—VLANs, trunking (802.1Q), STP, port mirroring, PoE.
• Days 11-12: Wireless networking—802.11 standards (a/b/g/n/ac/ax/be), channels, frequencies (2.4 GHz vs 5 GHz vs 6 GHz), SSID, wireless security (WPA2-Enterprise, WPA3, RADIUS).
• Days 13-14: WAN technologies—MPLS, SD-WAN, broadband types (DSL, cable, fiber, satellite), VPN types (site-to-site, client-to-site, IPSec, SSL/TLS). Cloud networking—IaaS, PaaS, SaaS, virtual switches, east-west traffic.

Week 3: Operations & Security (Days 15-21)

Network operations and security together account for over 40% of the exam. This week covers monitoring tools, documentation practices, and the security concepts that protect enterprise networks.

• Days 15-17: Network monitoring—SNMP (v2c, v3), syslog, NetFlow, packet capture with Wireshark. Documentation—network diagrams, baseline configurations, change management, rack diagrams, cable management.
• Days 18-19: Network security—firewalls (stateful vs stateless, NGFW), IDS/IPS, ACLs, NAC, port security, DHCP snooping. Common attacks—DDoS, ARP poisoning, VLAN hopping, man-in-the-middle, DNS spoofing.
• Days 20-21: Security hardening—disabling unused ports, firmware updates, network segmentation, DMZ design. Remote access—VPN configuration, RDP, SSH, Telnet (and why to avoid it).

Week 4: Troubleshooting & Final Review (Days 22-30)

Troubleshooting is the single largest domain on Network+ at 22%. This week you will practice the systematic troubleshooting methodology CompTIA expects and take multiple full-length practice exams.

• Days 22-24: Troubleshooting methodology—identify the problem, establish a theory, test the theory, establish a plan, implement the solution, verify functionality, document findings. Command-line tools: ping, tracert/traceroute, nslookup, dig, ipconfig/ifconfig, netstat, nmap.
• Days 25-26: Full-length practice exams (90 questions, timed at 90 minutes). Review every incorrect answer. Track scores by domain to identify remaining gaps.
• Days 27-28: Deep review of weak areas. Additional subnetting practice if scoring below 90% on subnetting questions. Review port numbers and protocol acronyms.
• Days 29-30: Final practice exam. Light review of flashcards. Rest and prepare mentally for exam day.
